└─────────────────────────────────────────────────┘

3.2 后端架构设计

采用清洁架构(Onion Architecture)原则：

1. 核心领域层：包含业务实体和核心业务逻辑
2. 应用服务层：协调领域对象完成用例
3. 接口适配层：包含Web API、身份验证等
4. 基础设施层：实现持久化、外部服务等

3.3 前端架构设计

采用模块化、组件化设计：

1. 核心模块：基础配置、工具函数、全局样式
2. 业务模块：按功能划分的独立模块
3. 共享组件：可复用的UI组件
4. 状态管理：集中式状态管理
5. 路由系统：基于权限的动态路由

3.4 微服务考虑

虽然初始版本采用单体架构，但设计上为未来微服务化预留扩展点：

1. 使用清晰的接口定义服务边界
2. 避免紧耦合的跨服务调用
3. 每个模块有独立的数据上下文
4. 使用事件驱动架构减少直接依赖

4. 后端.NET核心设计

5.2 核心模块实现

5.2.1 API服务封装

// src/api/http.ts
import axios, { AxiosInstance, AxiosRequestConfig, AxiosResponse } from 'axios';
import { useAuthStore } from '@/stores/auth';const http: AxiosInstance = axios.create({baseURL: import.meta.env.VITE_API_BASE_URL,timeout: 10000,
});// 请求拦截器
http.interceptors.request.use((config: AxiosRequestConfig) => {const authStore = useAuthStore();if (authStore.token) {config.headers = config.headers || {};config.headers['Authorization'] = `Bearer ${authStore.token}`;}return config;
});// 响应拦截器
http.interceptors.response.use((response: AxiosResponse) => {return response.data;},(error) => {if (error.response?.status === 401) {const authStore = useAuthStore();authStore.logout();window.location.href = '/login';}const message = error.response?.data?.message || error.message;console.error('API Error:', message);return Promise.reject(error);}
);export default http;// src/api/user.ts
import http from './http';export interface User {id: number;username: string;email: string;roles: string[];
}export const getUser = (id: number): Promise<User> => {return http.get(`/users/${id}`);
};export const getUsers = (params: any): Promise<PaginatedResult<User>> => {return http.get('/users', { params });
};export const createUser = (data: any): Promise<User> => {return http.post('/users', data);
};// 其他API函数...

5.2.2 状态管理(Pinia)

// src/stores/auth.ts
import { defineStore } from 'pinia';
import { login, logout, getUserInfo } from '@/api/auth';
import { User } from '@/api/user';interface AuthState {token: string | null;user: User | null;
}export const useAuthStore = defineStore('auth', {state: (): AuthState => ({token: localStorage.getItem('token'),user: null,}),getters: {isAuthenticated: (state) => !!state.token,roles: (state) => state.user?.roles || [],},actions: {async login(credentials: { username: string; password: string }) {const { token } = await login(credentials);this.token = token;localStorage.setItem('token', token);await this.fetchUser();},async fetchUser() {if (this.token) {this.user = await getUserInfo();}},async logout() {await logout();this.token = null;this.user = null;localStorage.removeItem('token');},},
});

5.2.3 路由配置

// src/router/index.ts
import { createRouter, createWebHistory, RouteRecordRaw } from 'vue-router';
import { useAuthStore } from '@/stores/auth';const routes: RouteRecordRaw[] = [{path: '/',component: () => import('@/layouts/MainLayout.vue'),meta: { requiresAuth: true },children: [{path: '',name: 'Dashboard',component: () => import('@/views/dashboard/DashboardView.vue'),},{path: 'users',name: 'Users',component: () => import('@/views/system/user/UserList.vue'),meta: { permission: 'users.view' },},// 其他路由...],},{path: '/login',name: 'Login',component: () => import('@/views/auth/LoginView.vue'),meta: { guestOnly: true },},
];const router = createRouter({history: createWebHistory(),routes,
});router.beforeEach(async (to, from, next) => {const authStore = useAuthStore();// 如果路由需要认证但用户未登录if (to.meta.requiresAuth && !authStore.isAuthenticated) {return next({ name: 'Login', query: { redirect: to.fullPath } });}// 如果路由仅允许游客访问但用户已登录if (to.meta.guestOnly && authStore.isAuthenticated) {return next({ name: 'Dashboard' });}// 检查权限if (to.meta.permission) {const hasPermission = await authStore.checkPermission(to.meta.permission);if (!hasPermission) {return next({ name: 'Forbidden' });}}next();
});export default router;

5.2.4 权限指令

// src/directives/permission.ts
import { Directive } from 'vue';
import { useAuthStore } from '@/stores/auth';export const permissionDirective: Directive = {mounted(el, binding) {const authStore = useAuthStore();const { value } = binding;if (value) {const hasPermission = authStore.roles.some(role => {return role.permissions.some(permission => permission.code === value);});if (!hasPermission) {el.parentNode?.removeChild(el);}}},
};// 在main.ts中注册
import { permissionDirective } from '@/directives/permission';app.directive('permission', permissionDirective);// 使用示例
<button v-permission="'users.create'">创建用户</button>

6. 数据库设计

6.1 核心表结构

6.1.1 用户表(Users)

CREATE TABLE Users (Id INT PRIMARY KEY IDENTITY(1,1),Username NVARCHAR(50) NOT NULL,Email NVARCHAR(100) NOT NULL,PasswordHash NVARCHAR(255) NOT NULL,PhoneNumber NVARCHAR(20),IsActive BIT NOT NULL DEFAULT 1,LastLoginTime DATETIME,CreatedAt DATETIME NOT NULL DEFAULT GETDATE(),UpdatedAt DATETIME NOT NULL DEFAULT GETDATE(),CreatedBy INT,UpdatedBy INT,CONSTRAINT UQ_Users_Username UNIQUE (Username),CONSTRAINT UQ_Users_Email UNIQUE (Email)
);

6.1.2 角色表(Roles)

CREATE TABLE Roles (Id INT PRIMARY KEY IDENTITY(1,1),Name NVARCHAR(50) NOT NULL,Description NVARCHAR(255),IsSystem BIT NOT NULL DEFAULT 0,CreatedAt DATETIME NOT NULL DEFAULT GETDATE(),UpdatedAt DATETIME NOT NULL DEFAULT GETDATE(),CONSTRAINT UQ_Roles_Name UNIQUE (Name)
);

6.1.3 权限表(Permissions)

CREATE TABLE Permissions (Id INT PRIMARY KEY IDENTITY(1,1),Name NVARCHAR(50) NOT NULL,Code NVARCHAR(50) NOT NULL,Module NVARCHAR(50) NOT NULL,Description NVARCHAR(255),CreatedAt DATETIME NOT NULL DEFAULT GETDATE(),CONSTRAINT UQ_Permissions_Code UNIQUE (Code)
);

6.1.4 用户角色关联表(UserRoles)

CREATE TABLE UserRoles (UserId INT NOT NULL,RoleId INT NOT NULL,CreatedAt DATETIME NOT NULL DEFAULT GETDATE(),PRIMARY KEY (UserId, RoleId),FOREIGN KEY (UserId) REFERENCES Users(Id) ON DELETE CASCADE,FOREIGN KEY (RoleId) REFERENCES Roles(Id) ON DELETE CASCADE
);

6.1.5 角色权限关联表(RolePermissions)

CREATE TABLE RolePermissions (RoleId INT NOT NULL,PermissionId INT NOT NULL,CreatedAt DATETIME NOT NULL DEFAULT GETDATE(),PRIMARY KEY (RoleId, PermissionId),FOREIGN KEY (RoleId) REFERENCES Roles(Id) ON DELETE CASCADE,FOREIGN KEY (PermissionId) REFERENCES Permissions(Id) ON DELETE CASCADE
);

6.1.6 系统日志表(SystemLogs)

);

6.2 索引设计

-- 用户表索引
CREATE INDEX IX_Users_Email ON Users(Email);
CREATE INDEX IX_Users_PhoneNumber ON Users(PhoneNumber);
CREATE INDEX IX_Users_IsActive ON Users(IsActive);-- 日志表索引
CREATE INDEX IX_SystemLogs_Level ON SystemLogs(Level);
CREATE INDEX IX_SystemLogs_UserId ON SystemLogs(UserId);
CREATE INDEX IX_SystemLogs_CreatedAt ON SystemLogs(CreatedAt);
CREATE INDEX IX_SystemLogs_RequestPath ON SystemLogs(RequestPath);

6.3 数据初始化脚本

-- 初始化超级管理员角色
INSERT INTO Roles (Name, Description, IsSystem)
VALUES ('SuperAdmin', '超级管理员', 1);-- 初始化基本权限
INSERT INTO Permissions (Name, Code, Module, Description)
VALUES 
('用户管理-查看', 'users.view', 'system', '查看用户列表和详情'),
('用户管理-创建', 'users.create', 'system', '创建新用户'),
('用户管理-编辑', 'users.update', 'system', '编辑用户信息'),
('用户管理-删除', 'users.delete', 'system', '删除用户'),
('角色管理-查看', 'roles.view', 'system', '查看角色列表和详情'),
('角色管理-创建', 'roles.create', 'system', '创建新角色'),
('角色管理-编辑', 'roles.update', 'system', '编辑角色信息'),
('角色管理-删除', 'roles.delete', 'system', '删除角色');-- 为超级管理员角色分配所有权限
INSERT INTO RolePermissions (RoleId, PermissionId)
SELECT r.Id, p.Id
FROM Roles r
CROSS JOIN Permissions p
WHERE r.Name = 'SuperAdmin';-- 初始化超级管理员用户
DECLARE @adminId INT;
INSERT INTO Users (Username, Email, PasswordHash, IsActive)
VALUES ('admin', 'admin@example.com', '$2a$11$WrL5JZ6U3n7GkGKjZ8bVf.3dQY9wLmN1JfzXcVvV6yKt5rHs3s4XW', 1);SET @adminId = SCOPE_IDENTITY();-- 分配超级管理员角色
INSERT INTO UserRoles (UserId, RoleId)
VALUES (@adminId, (SELECT Id FROM Roles WHERE Name = 'SuperAdmin'));

7. API设计规范

7.1 RESTful API设计原则

1. 资源命名：

   • 使用名词复数形式表示资源
   • 例如：/users, /roles, /permissions

2. HTTP方法：

   • GET：获取资源
   • POST：创建资源
   • PUT：完整更新资源
   • PATCH：部分更新资源
   • DELETE：删除资源

3. 端点示例：

   GET    /users          - 获取用户列表
   POST   /users          - 创建新用户
   GET    /users/{id}     - 获取指定用户
   PUT    /users/{id}     - 更新指定用户
   DELETE /users/{id}     - 删除指定用户
   GET    /users/{id}/roles - 获取用户的角色
   

7.2 请求与响应规范

7.2.1 请求头

Authorization: Bearer {token}
Content-Type: application/json
Accept: application/json

7.2.2 查询参数

• 分页：?page=1&size=10
• 排序：?sort=name,asc&sort=createdAt,desc
• 过滤：?name=admin&status=1

7.2.3 响应格式

成功响应：

{"data": {"id": 1,"username": "admin","email": "admin@example.com"},"message": "操作成功","success": true
}

分页响应：

{"data": {"items": [{"id": 1,"username": "admin"}],"total": 1,"page": 1,"size": 10},"message": "操作成功","success": true
}

错误响应：

{"error": {"code": "ValidationError","message": "请求参数无效","details": {"username": ["用户名不能为空"],"email": ["邮箱格式不正确"]}},"success": false
}

7.3 版本控制

在URL中包含API版本：

/api/v1/users
/api/v2/users

7.4 数据格式

1. 日期时间：ISO 8601格式 "2023-05-20T12:34:56Z"
2. 枚举：使用字符串值而非数字
3. 布尔值：使用 true/false
4. 空值：使用 null

7.5 错误代码

HTTP状态码	错误代码	描述
400	BadRequest	请求参数无效
401	Unauthorized	未认证或token过期
403	Forbidden	无权限访问
404	NotFound	资源不存在
409	Conflict	资源冲突
500	InternalServerError	服务器内部错误

8. 认证与授权方案

8.1 认证流程

1. 登录：

   • 用户提交用户名和密码
   • 服务器验证凭证
   • 生成JWT token返回给客户端

2. 访问API：

   • 客户端在请求头中添加 Authorization: Bearer {token}
   • 服务器验证token有效性
   • 允许或拒绝请求

8.2 JWT实现

// JWT服务实现
public class JwtService : IJwtService
{private readonly JwtSettings _jwtSettings;public JwtService(IOptions<JwtSettings> jwtSettings){_jwtSettings = jwtSettings.Value;}public string GenerateToken(User user){var claims = new[]{new Claim(JwtRegisteredClaimNames.Sub, user.Id.ToString()),new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString()),new Claim(JwtRegisteredClaimNames.UniqueName, user.Username),new Claim(ClaimTypes.Email, user.Email),new Claim("permissions", JsonSerializer.Serialize(user.Permissions))};var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_jwtSettings.Secret));var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);var token = new JwtSecurityToken(issuer: _jwtSettings.Issuer,audience: _jwtSettings.Audience,claims: claims,expires: DateTime.UtcNow.AddMinutes(_jwtSettings.ExpiryMinutes),signingCredentials: creds);return new JwtSecurityTokenHandler().WriteToken(token);}public int? ValidateToken(string token){if (string.IsNullOrEmpty(token))return null;var tokenHandler = new JwtSecurityTokenHandler();var key = Encoding.UTF8.GetBytes(_jwtSettings.Secret);try{tokenHandler.ValidateToken(token, new TokenValidationParameters{ValidateIssuerSigningKey = true,IssuerSigningKey = new SymmetricSecurityKey(key),ValidateIssuer = true,ValidIssuer = _jwtSettings.Issuer,ValidateAudience = true,ValidAudience = _jwtSettings.Audience,ValidateLifetime = true,ClockSkew = TimeSpan.Zero}, out var validatedToken);var jwtToken = (JwtSecurityToken)validatedToken;var userId = int.Parse(jwtToken.Claims.First(x => x.Type == "sub").Value);return userId;}catch{return null;}}
}

8.3 授权策略

// 权限策略注册
services.AddAuthorization(options =>
{// 基于角色的策略options.AddPolicy("AdminOnly", policy => policy.RequireRole("Admin"));// 基于声明的策略options.AddPolicy("ManageUsers", policy => policy.RequireClaim("permission", "users.manage"));// 自定义需求策略options.AddPolicy("Over18", policy =>policy.Requirements.Add(new MinimumAgeRequirement(18)));
});// 自定义授权处理器
public class PermissionAuthorizationHandler : AuthorizationHandler<PermissionRequirement>
{protected override Task HandleRequirementAsync(AuthorizationHandlerContext context,PermissionRequirement requirement){if (context.User.HasClaim(c => c.Type == "permissions" && c.Value.Contains(requirement.Permission))){context.Succeed(requirement);}return Task.CompletedTask;}
}// 控制器中使用
[Authorize(Policy = "ManageUsers")]
public class UsersController : ControllerBase
{// ...
}

8.4 刷新令牌机制

public class TokenService : ITokenService
{public async Task<AuthenticateResponse> AuthenticateAsync(User user, string ipAddress){var jwtToken = GenerateJwtToken(user);var refreshToken = GenerateRefreshToken(ipAddress);user.RefreshTokens.Add(refreshToken);await _context.SaveChangesAsync();return new AuthenticateResponse(user, jwtToken, refreshToken.Token);}public async Task<AuthenticateResponse> RefreshTokenAsync(string token, string ipAddress){var user = await _context.Users.Include(u => u.RefreshTokens).FirstOrDefaultAsync(u => u.RefreshTokens.Any(t => t.Token == token));if (user == null)throw new AppException("无效的刷新令牌");var refreshToken = user.RefreshTokens.Single(x => x.Token == token);if (!refreshToken.IsActive)throw new AppException("无效的刷新令牌");// 替换旧刷新令牌var newRefreshToken = GenerateRefreshToken(ipAddress);refreshToken.Revoked = DateTime.UtcNow;refreshToken.RevokedByIp = ipAddress;refreshToken.ReplacedByToken = newRefreshToken.Token;user.RefreshTokens.Add(newRefreshToken);await _context.SaveChangesAsync();var jwtToken = GenerateJwtToken(user);return new AuthenticateResponse(user, jwtToken, newRefreshToken.Token);}public async Task RevokeTokenAsync(string token, string ipAddress){var user = await _context.Users.Include(u => u.RefreshTokens).FirstOrDefaultAsync(u => u.RefreshTokens.Any(t => t.Token == token));if (user == null)throw new AppException("无效的刷新令牌");var refreshToken = user.RefreshTokens.Single(x => x.Token == token);if (!refreshToken.IsActive)throw new AppException("无效的刷新令牌");refreshToken.Revoked = DateTime.UtcNow;refreshToken.RevokedByIp = ipAddress;await _context.SaveChangesAsync();}private RefreshToken GenerateRefreshToken(string ipAddress){return new RefreshToken{Token = RandomTokenString(),Expires = DateTime.UtcNow.AddDays(7),Created = DateTime.UtcNow,CreatedByIp = ipAddress};}private string RandomTokenString(){using var rngCryptoServiceProvider = new RNGCryptoServiceProvider();var randomBytes = new byte[40];rngCryptoServiceProvider.GetBytes(randomBytes);return BitConverter.ToString(randomBytes).Replace("-", "");}
}

9. 异常处理与日志系统

9.1 异常处理策略

9.1.1 自定义异常体系

// 基础异常类
public class AppException : Exception
{public AppException() { }public AppException(string message) : base(message) { }public AppException(string message, Exception inner) : base(message, inner) { }
}// 业务异常
public class BusinessException : AppException
{public string Code { get; }public BusinessException(string code, string message) : base(message){Code = code;}
}// 验证异常
public class ValidationException : AppException
{public IDictionary<string, string[]> Errors { get; }public ValidationException() : base("一个或多个验证失败"){Errors = new Dictionary<string, string[]>();}public ValidationException(IDictionary<string, string[]> errors) : this(){Errors = errors;}
}// 未授权异常
public class UnauthorizedException : AppException
{public UnauthorizedException(string message) : base(message) { }
}// 未找到异常
public class NotFoundException : AppException
{public NotFoundException(string name, object key) : base($"实体 \"{name}\" ({key}) 未找到") { }
}

9.1.2 全局异常处理

// 异常中间件
public class ExceptionMiddleware
{private readonly RequestDelegate _next;private readonly ILogger<ExceptionMiddleware> _logger;public ExceptionMiddleware(RequestDelegate next, ILogger<ExceptionMiddleware> logger){_next = next;_logger = logger;}public async Task InvokeAsync(HttpContext context){try{await _next(context);}catch (Exception ex){_logger.LogError(ex, "An unhandled exception has occurred");await HandleExceptionAsync(context, ex);}}private static Task HandleExceptionAsync(HttpContext context, Exception exception){context.Response.ContentType = "application/json";var statusCode = exception switch{ValidationException => StatusCodes.Status400BadRequest,NotFoundException => StatusCodes.Status404NotFound,UnauthorizedException => StatusCodes.Status401Unauthorized,BusinessException => StatusCodes.Status400BadRequest,_ => StatusCodes.Status500InternalServerError};context.Response.StatusCode = statusCode;var response = new{status = statusCode,message = exception.Message,details = exception is ValidationException validationException ? validationException.Errors : null,code = exception is BusinessException businessException? businessException.Code: null};return context.Response.WriteAsync(JsonSerializer.Serialize(response));}
}

9.2 日志系统设计

9.2.1 日志配置

// 使用Serilog配置
Log.Logger = new LoggerConfiguration().MinimumLevel.Information().MinimumLevel.Override("Microsoft", LogEventLevel.Warning).MinimumLevel.Override("Microsoft.Hosting.Lifetime", LogEventLevel.Information).MinimumLevel.Override("System", LogEventLevel.Warning).Enrich.FromLogContext().WriteTo.Console().WriteTo.File(path: "Logs/log-.txt",rollingInterval: RollingInterval.Day,retainedFileCountLimit: 7,shared: true).WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri("http://localhost:9200")){AutoRegisterTemplate = true,IndexFormat = "fastproduction-{0:yyyy.MM}"}).CreateLogger();// 在Program.cs中
builder.Host.UseSerilog();

9.2.2 结构化日志

// 控制器中使用结构化日志
[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{private readonly ILogger<WeatherForecastController> _logger;public WeatherForecastController(ILogger<WeatherForecastController> logger){_logger = logger;}[HttpGet]public IEnumerable<WeatherForecast> Get(){_logger.LogInformation("Getting weather forecast with {Count} items", 5);try{// 业务逻辑}catch (Exception ex){_logger.LogError(ex, "Failed to get weather forecast");throw;}}
}

9.2.3 请求日志中间件

public class RequestLoggingMiddleware
{private readonly RequestDelegate _next;private readonly ILogger<RequestLoggingMiddleware> _logger;public RequestLoggingMiddleware(RequestDelegate next, ILogger<RequestLoggingMiddleware> logger){_next = next;_logger = logger;}public async Task Invoke(HttpContext context){var startTime = DateTime.UtcNow;try{await _next(context);var elapsedMs = (DateTime.UtcNow - startTime).TotalMilliseconds;_logger.LogInformation("Request {Method} {Path} completed in {Elapsed}ms with {StatusCode}",context.Request.Method,context.Request.Path,elapsedMs,context.Response.StatusCode);}catch (Exception ex){var elapsedMs = (DateTime.UtcNow - startTime).TotalMilliseconds;_logger.LogError(ex,"Request {Method} {Path} failed in {Elapsed}ms",context.Request.Method,context.Request.Path,elapsedMs);throw;}}
}

10. 性能优化策略

10.1 数据库优化

10.1.1 查询优化

// 避免N+1查询问题
// 错误方式 - 会导致N+1查询
var users = await _context.Users.ToListAsync();
foreach (var user in users)
{var roles = await _context.Roles.Where(r => r.UserRoles.Any(ur => ur.UserId == user.Id)).ToListAsync();
}// 正确方式 - 使用Include预先加载
var usersWithRoles = await _context.Users.Include(u => u.UserRoles).ThenInclude(ur => ur.Role).ToListAsync();// 使用投影只选择需要的字段
var userDtos = await _context.Users.Where(u => u.IsActive).Select(u => new UserDto{Id = u.Id,Username = u.Username,Email = u.Email}).ToListAsync();

10.1.2 索引优化

-- 为常用查询条件添加索引
CREATE INDEX IX_Users_IsActive ON Users(IsActive);
CREATE INDEX IX_Users_Email ON Users(Email);-- 复合索引
CREATE INDEX IX_Orders_CustomerId_Status ON Orders(CustomerId, Status);

10.1.3 批量操作

// 批量插入
var newUsers = new List<User>();
for (int i = 0; i < 1000; i++)
{newUsers.Add(new User { /* ... */ });
}await _context.BulkInsertAsync(newUsers);// 批量更新
await _context.Users.Where(u => u.LastLoginTime < DateTime.Now.AddYears(-1)).BatchUpdateAsync(u => new User { IsActive = false });// 批量删除
await _context.Users.Where(u => !u.IsActive && u.CreatedAt < DateTime.Now.AddYears(-2)).BatchDeleteAsync();

10.2 缓存策略

10.2.1 多级缓存

// 缓存服务实现
public class CacheService : ICacheService
{private readonly IMemoryCache _memoryCache;private readonly IDistributedCache _distributedCache;public CacheService(IMemoryCache memoryCache,IDistributedCache distributedCache){_memoryCache = memoryCache;_distributedCache = distributedCache;}public async Task<T> GetOrCreateAsync<T>(string key,Func<Task<T>> factory,TimeSpan? memoryCacheExpiration = null,TimeSpan? distributedCacheExpiration = null,CancellationToken cancellationToken = default){// 首先尝试从内存缓存获取if (_memoryCache.TryGetValue(key, out T memoryValue)){return memoryValue;}// 然后尝试从分布式缓存获取var distributedValue = await _distributedCache.GetStringAsync(key, cancellationToken);if (distributedValue != null){var value = JsonSerializer.Deserialize<T>(distributedValue);// 存入内存缓存_memoryCache.Set(key, value, memoryCacheExpiration ?? TimeSpan.FromMinutes(5));return value;}// 如果缓存中都没有，则调用工厂方法获取数据var result = await factory();// 存入分布式缓存await _distributedCache.SetStringAsync(key,JsonSerializer.Serialize(result),new DistributedCacheEntryOptions{AbsoluteExpirationRelativeToNow = distributedCacheExpiration ?? TimeSpan.FromHours(1)},cancellationToken);// 存入内存缓存_memoryCache.Set(key, result, memoryCacheExpiration ?? TimeSpan.FromMinutes(5));return result;}
}

10.2.2 缓存失效策略

// 缓存失效装饰器
public class CachedUserService : IUserService
{private readonly IUserService _inner;private readonly ICacheService _cache;public CachedUserService(IUserService inner, ICacheService cache){_inner = inner;_cache = cache;}public async Task<UserDto> GetByIdAsync(int id){var cacheKey = $"user:{id}";return await _cache.GetOrCreateAsync(cacheKey, () => _inner.GetByIdAsync(id));}public async Task UpdateAsync(int id, UpdateUserDto userDto){await _inner.UpdateAsync(id, userDto);// 更新后使缓存失效var cacheKey = $"user:{id}";await _cache.RemoveAsync(cacheKey);}
}

10.3 响应压缩

// 在Program.cs中配置响应压缩
builder.Services.AddResponseCompression(options =>
{options.Providers.Add<BrotliCompressionProvider>();options.Providers.Add<GzipCompressionProvider>();options.MimeTypes = ResponseCompressionDefaults.MimeTypes.Concat(new[]{"application/json","text/json","text/plain","application/javascript","text/css","text/html","application/xml","text/xml"});
});app.UseResponseCompression();

10.4 异步编程

// 控制器中使用异步方法
[HttpGet("{id}")]
public async Task<ActionResult<UserDto>> GetUser(int id)
{var user = await _userService.GetByIdAsync(id);if (user == null){return NotFound();}return Ok(user);
}// 服务层异步方法
public async Task<UserDto> GetByIdAsync(int id)
{var user = await _repository.GetByIdAsync(id);if (user == null){throw new NotFoundException(nameof(User), id);}return _mapper.Map<UserDto>(user);
}

10.5 性能监控

// 添加Application Insights
builder.Services.AddApplicationInsightsTelemetry();// 自定义性能计数器
public class PerformanceCounterMiddleware
{private readonly RequestDelegate _next;private readonly ILogger<PerformanceCounterMiddleware> _logger;private readonly Stopwatch _stopwatch;public PerformanceCounterMiddleware(RequestDelegate next,ILogger<PerformanceCounterMiddleware> logger){_next = next;_logger = logger;_stopwatch = new Stopwatch();}public async Task InvokeAsync(HttpContext context){_stopwatch.Restart();await _next(context);_stopwatch.Stop();if (_stopwatch.ElapsedMilliseconds > 500){_logger.LogWarning("Request {Method} {Path} took {Elapsed}ms",context.Request.Method,context.Request.Path,_stopwatch.ElapsedMilliseconds);}}
}

13. 监控与运维

13.1 监控体系

13.1.1 应用性能监控(APM)

// 添加Application Insights
builder.Services.AddApplicationInsightsTelemetry(options =>
{options.ConnectionString = builder.Configuration["ApplicationInsights:ConnectionString"];options.EnableAdaptiveSampling = false;
});// 自定义遥测
public class UsersController : ControllerBase
{private readonly TelemetryClient _telemetryClient;public UsersController(TelemetryClient telemetryClient){_telemetryClient = telemetryClient;}[HttpGet("{id}")]public async Task<ActionResult<UserDto>> GetUser(int id){// 自定义事件_telemetryClient.TrackEvent("GetUser", new Dictionary<string, string>{["userId"] = id.ToString()});try{var user = await _userService.GetByIdAsync(id);// 自定义指标_telemetryClient.GetMetric("UserRetrievalTime").TrackValue(stopwatch.ElapsedMilliseconds);return Ok(user);}catch (Exception ex){// 自定义异常_telemetryClient.TrackException(ex, new Dictionary<string, string>{["userId"] = id.ToString()});throw;}}
}

13.1.2 健康检查

// 添加健康检查服务
builder.Services.AddHealthChecks().AddCheck<DatabaseHealthCheck>("database").AddRedis(builder.Configuration.GetConnectionString("Redis")).AddRabbitMQ(builder.Configuration.GetConnectionString("RabbitMQ")).AddApplicationInsightsPublisher();// 自定义健康检查
public class DatabaseHealthCheck : IHealthCheck
{private readonly AppDbContext _context;public DatabaseHealthCheck(AppDbContext context){_context = context;}public async Task<HealthCheckResult> CheckHealthAsync(HealthCheckContext context,CancellationToken cancellationToken = default){try{await _context.Database.CanConnectAsync(cancellationToken);return HealthCheckResult.Healthy();}catch (Exception ex){return HealthCheckResult.Unhealthy("Database connection failed", ex);}}
}// 在Program.cs中配置健康检查端点
app.MapHealthChecks("/health", new HealthCheckOptions
{ResponseWriter = async (context, report) =>{var result = JsonSerializer.Serialize(new{status = report.Status.ToString(),checks = report.Entries.Select(e => new{name = e.Key,status = e.Value.Status.ToString(),description = e.Value.Description,exception = e.Value.Exception?.Message})});context.Response.ContentType = "application/json";await context.Response.WriteAsync(result);}
});

13.2 日志聚合

13.2.1 ELK Stack配置

}filter {mutate {remove_field => ["@version", "host"]}
}output {elasticsearch {hosts => ["elasticsearch:9200"]index => "fastproduction-%{+YYYY.MM.dd}"}
}

13.3 告警系统

13.3.1 Prometheus + Alertmanager

# prometheus.yml
global:scrape_interval: 15sevaluation_interval: 15srule_files:- 'alert.rules'scrape_configs:- job_name: 'fastproduction'metrics_path: '/metrics'static_configs:- targets: ['backend:80', 'frontend:80']alerting:alertmanagers:- static_configs:- targets: ['alertmanager:9093']

13.4 运维工具

13.4.1 数据库迁移

// 使用EF Core迁移
dotnet ef migrations add InitialCreate
dotnet ef database update// 生产环境迁移脚本
dotnet ef migrations script --idempotent --output migrations.sql

13.4.2 维护任务

// 使用Hangfire执行后台任务
public class MaintenanceService
{private readonly AppDbContext _context;private readonly ILogger<MaintenanceService> _logger;public MaintenanceService(AppDbContext context,ILogger<MaintenanceService> logger){_context = context;_logger = logger;}[AutomaticRetry(Attempts = 3)]public async Task CleanupOldLogs(){var cutoffDate = DateTime.UtcNow.AddMonths(-3);_logger.LogInformation("Cleaning up logs older than {CutoffDate}", cutoffDate);var count = await _context.Logs.Where(l => l.CreatedAt < cutoffDate).BatchDeleteAsync();_logger.LogInformation("Deleted {Count} old log entries", count);}[AutomaticRetry(Attempts = 3)]public async Task BackupDatabase(){_logger.LogInformation("Starting database backup");// 执行备份逻辑_logger.LogInformation("Database backup completed successfully");}
}

14. 开发流程与规范

14.1 Git工作流

采用Git Flow工作流：

1. 主分支(main)：稳定版本，对应生产环境
2. 开发分支(develop)：集成开发功能，对应测试环境
3. 功能分支(feature/xxx)：开发新功能
4. 修复分支(hotfix/xxx)：紧急修复生产问题
5. 发布分支(release/xxx)：准备发布版本

14.2 代码审查

1. Pull Request模板：

   ## 变更描述## 相关Issue## 测试说明## 截图(如适用)
   

2. 审查清单：

   • 代码是否符合编码规范
   • 是否有适当的单元测试
   • 是否影响现有功能
   • 是否有性能问题
   • 是否有安全风险

14.3 编码规范

14.3.1 C#编码规范

1. 命名约定：

   • 类名：PascalCase
   • 方法名：PascalCase
   • 变量名：camelCase
   • 私有字段：_camelCase
   • 常量：UPPER_CASE

2. 代码组织：

   • 使用region组织代码
   • 成员顺序：字段 > 属性 > 构造函数 > 方法

3. 最佳实践：

   • 使用async/await进行异步编程
   • 避免使用魔法字符串
   • 使用依赖注入
   • 遵循SOLID原则

14.3.2 TypeScript/Vue编码规范

1. 组件命名：

   • 单文件组件：PascalCase (UserList.vue)
   • 组件引用：PascalCase

2. 代码结构：

   <script setup lang="ts">
   // 导入顺序: Vue > 第三方库 > 本地组件 > 类型
   import { ref } from 'vue';
   import axios from 'axios';
   import UserForm from './UserForm.vue';
   import type { User } from '@/types';// 组合式API顺序: props > emits > 响应式状态 > 计算属性 > 方法 > 生命周期
   const props = defineProps<{ userId: number }>();const emit = defineEmits(['update', 'delete']);const user = ref<User | null>(null);const fullName = computed(() => {return `${user.value?.firstName} ${user.value?.lastName}`;
   });async function fetchUser() {// ...
   }onMounted(() => {fetchUser();
   });
   </script>
   

3. 最佳实践：

   • 使用Composition API
   • 为组件props定义类型
   • 避免直接操作DOM
   • 使用Pinia进行状态管理

14.4 提交消息规范

使用Conventional Commits规范：

<类型>[可选 范围]: <描述>[可选 正文][可选 脚注]

示例：

feat(users): add user deletion functionalityAdd the ability to delete users from the admin panel. Includes API endpoint, service method and UI component.Closes #123

常见类型：

• feat：新功能
• fix：错误修复
• docs：文档变更
• style：代码样式变更
• refactor：代码重构
• test：测试相关
• chore：构建或辅助工具变更

15. 安全考虑

15.1 安全防护措施

15.1.1 输入验证

// 使用FluentValidation进行复杂验证
public class CreateUserDtoValidator : AbstractValidator<CreateUserDto>
{public CreateUserDtoValidator(){RuleFor(x => x.Username).NotEmpty().WithMessage("用户名不能为空").Length(3, 20).WithMessage("用户名长度必须在3到20个字符之间").Matches("^[a-zA-Z0-9_]+$").WithMessage("用户名只能包含字母、数字和下划线");RuleFor(x => x.Email).NotEmpty().WithMessage("邮箱不能为空").EmailAddress().WithMessage("邮箱格式不正确");RuleFor(x => x.Password).NotEmpty().WithMessage("密码不能为空").MinimumLength(8).WithMessage("密码长度至少8个字符").Matches("[A-Z]").WithMessage("密码必须包含至少一个大写字母").Matches("[a-z]").WithMessage("密码必须包含至少一个小写字母").Matches("[0-9]").WithMessage("密码必须包含至少一个数字");}
}// 在控制器中使用
[HttpPost]
public async Task<ActionResult<UserDto>> CreateUser([FromBody] CreateUserDto dto)
{var validationResult = await _validator.ValidateAsync(dto);if (!validationResult.IsValid){throw new ValidationException(validationResult.ToDictionary());}// 处理逻辑...
}

15.1.2 输出编码

// 在Razor视图中自动编码输出
<p>@Model.UserInput</p>// 对于需要原始HTML的情况
<p>@Html.Raw(Model.TrustedHtml)</p>

15.1.3 CSRF防护

// 在Program.cs中配置
builder.Services.AddAntiforgery(options =>
{options.HeaderName = "X-CSRF-TOKEN";options.Cookie.SecurePolicy = CookieSecurePolicy.Always;
});// 在控制器中使用
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult UpdateProfile(ProfileViewModel model)
{// ...
}

15.2 安全头配置

// 添加安全中间件
app.Use(async (context, next) =>
{// 设置安全相关的HTTP头context.Response.Headers.Add("X-Content-Type-Options", "nosniff");context.Response.Headers.Add("X-Frame-Options", "DENY");context.Response.Headers.Add("X-XSS-Protection", "1; mode=block");context.Response.Headers.Add("Referrer-Policy", "no-referrer");context.Response.Headers.Add("Content-Security-Policy", "default-src 'self'; script-src 'self' 'unsafe-inline' cdn.example.com; style-src 'self' 'unsafe-inline'; img-src 'self' data:;");await next();
});

15.3 安全审计

15.3.1 依赖安全检查

# 检查NuGet包漏洞
dotnet list package --vulnerable# 检查npm包漏洞
npm audit

15.3.2 静态代码分析

使用SonarQube进行静态代码分析：

# .github/workflows/sonarcloud.yml
name: SonarCloud Scanon:push:branches: [ main ]pull_request:types: [ opened, synchronize, reopened ]jobs:build:runs-on: ubuntu-lateststeps:- uses: actions/checkout@v2with:fetch-depth: 0- name: Setup .NETuses: actions/setup-dotnet@v1with:dotnet-version: '7.0.x'- name: Install SonarCloud scannerrun: dotnet tool install --global dotnet-sonarscanner- name: SonarCloud Scanrun: |dotnet sonarscanner begin /k:"your-project-key" /d:sonar.login="${{ secrets.SONAR_TOKEN }}" /d:sonar.host.url="https://sonarcloud.io"dotnet builddotnet sonarscanner end /d:sonar.login="${{ secrets.SONAR_TOKEN }}"

16. 扩展性设计

16.1 插件系统设计

// 插件接口定义
public interface IPlugin
{string Name { get; }string Version { get; }void Initialize(IServiceCollection services);void Configure(IApplicationBuilder app);
}// 插件管理器
public class PluginManager
{private readonly List<IPlugin> _plugins = new();public void LoadPlugins(string pluginsPath){foreach (var file in Directory.GetFiles(pluginsPath, "*.dll")){var assembly = Assembly.LoadFrom(file);foreach (var type in assembly.GetTypes().Where(t => typeof(IPlugin).IsAssignableFrom(t) && !t.IsAbstract)){if (Activator.CreateInstance(type) is IPlugin plugin){_plugins.Add(plugin);}}}}public void InitializePlugins(IServiceCollection services){foreach (var plugin in _plugins){plugin.Initialize(services);}}public void ConfigurePlugins(IApplicationBuilder app){foreach (var plugin in _plugins){plugin.Configure(app);}}
}// 示例插件
public class ReportingPlugin : IPlugin
{public string Name => "Reporting Plugin";public string Version => "1.0";public void Initialize(IServiceCollection services){services.AddScoped<IReportService, ReportService>();}public void Configure(IApplicationBuilder app){app.Map("/reporting", builder =>{builder.UseEndpoints(endpoints =>{endpoints.MapControllers();});});}
}

16.2 模块化设计

16.2.1 模块定义

public interface IModule
{IServiceCollection RegisterModule(IServiceCollection services);IEndpointRouteBuilder MapEndpoints(IEndpointRouteBuilder endpoints);
}public static class ModuleExtensions
{public static IServiceCollection AddModules(this IServiceCollection services){var modules = DiscoverModules();foreach (var module in modules){module.RegisterModule(services);}return services;}public static WebApplication MapModules(this WebApplication app){var modules = DiscoverModules();foreach (var module in modules){module.MapEndpoints(app);}return app;}private static IEnumerable<IModule> DiscoverModules(){return typeof(IModule).Assembly.GetTypes().Where(p => p.IsClass && p.IsAssignableTo(typeof(IModule))).Select(Activator.CreateInstance).Cast<IModule>();}
}

16.2.2 用户模块示例

public class UserModule : IModule
{public IServiceCollection RegisterModule(IServiceCollection services){services.AddScoped<IUserService, UserService>();services.AddScoped<IUserRepository, UserRepository>();return services;}public IEndpointRouteBuilder MapEndpoints(IEndpointRouteBuilder endpoints){endpoints.MapGet("/api/users", async (IUserService userService) =>{var users = await userService.GetAllAsync();return Results.Ok(users);});// 其他端点...return endpoints;}
}

16.3 动态功能开关

// 功能标志服务
public interface IFeatureService
{bool IsEnabled(string feature);Task SetFeatureStateAsync(string feature, bool enabled);
}// 基于数据库的实现
public class DatabaseFeatureService : IFeatureService
{private readonly AppDbContext _context;public DatabaseFeatureService(AppDbContext context){_context = context;}public bool IsEnabled(string feature){return _context.FeatureFlags.FirstOrDefault(f => f.Name == feature)?.IsEnabled ?? false;}public async Task SetFeatureStateAsync(string feature, bool enabled){var flag = await _context.FeatureFlags.FirstOrDefaultAsync(f => f.Name == feature);if (flag == null){flag = new FeatureFlag { Name = feature };_context.FeatureFlags.Add(flag);}flag.IsEnabled = enabled;await _context.SaveChangesAsync();}
}// 使用特性标记
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)]
public class FeatureFlagAttribute : Attribute
{public string Feature { get; }public FeatureFlagAttribute(string feature){Feature = feature;}
}// 特性过滤器
public class FeatureFlagFilter : IAsyncActionFilter
{private readonly IFeatureService _featureService;public FeatureFlagFilter(IFeatureService featureService){_featureService = featureService;}public async Task OnActionExecutionAsync(ActionExecutingContext context,ActionExecutionDelegate next){var featureAttributes = context.ActionDescriptor.EndpointMetadata.OfType<FeatureFlagAttribute>().ToList();if (featureAttributes.Any()){foreach (var attr in featureAttributes){if (!_featureService.IsEnabled(attr.Feature)){context.Result = new NotFoundResult();return;}}}await next();}
}// 在控制器中使用
[FeatureFlag("new-user-interface")]
[HttpGet("new-ui")]
public IActionResult NewUserInterface()
{return View();
}
