现在开始Phase 2的开发。首先实现后端的股票CRUD操作和组合管理功能。## 第一步：实现股票验证服务```typescript
import axios from 'axios';export interface StockValidation {symbol: string;isValid: boolean;name?: string;exchange?: string;sector?: string;industry?: string;error?: string;

第三步：创建组合管理控制器

import { Request, Response } from 'express';
import { prisma } from '../index';// 获取用户投资组合列表

第四步：更新路由配置

import { Router } from 'express';
import {getStocks,getStockBySymbol,addStock,updateStock,deleteStock,validateStock,batchStockOperation,addToWatchlist,removeFromWatchlist,getStockHistory,getStockNews
} from '../controllers/stockController';
import { authenticateToken } from '../middleware/auth';const router = Router();// 公开路由 - 不需要认证
router.get('/', getStocks); // 获取股票列表
router.get('/validate/:symbol', validateStock); // 验证股票代码
router.get('/:symbol/history', getStockHistory); // 获取股票历史数据
router.get('/:symbol/news', getStockNews); // 获取股票新闻
router.get('/:symbol', getStockBySymbol); // 获取股票详情// 需要认证的路由
router.post('/', authenticateToken, addStock); // 添加股票
router.put('/:symbol', authenticateToken, updateStock); // 更新股票信息
router.delete('/:symbol', authenticateToken, deleteStock); // 删除股票
router.post('/batch', authenticateToken, batchStockOperation); // 批量操作
router.post('/:symbol/watchlist', authenticateToken, addToWatchlist); // 添加到观察列表
router.delete('/:symbol/watchlist', authenticateToken, removeFromWatchlist); // 从观察列表移除export default router;

继续Phase 2的开发。现在更新路由配置，添加新的API端点。

第四步：更新股票路由配置

import { Router } from 'express';
import {getStocks,getStockBySymbol,addStock,updateStock,deleteStock,validateStock,batchStockOperation,addToWatchlist,removeFromWatchlist,getStockHistory,getStockNews
} from '../controllers/stockController';
import { authenticateToken } from '../middleware/auth';const router = Router();// 公开路由 - 不需要认证
router.get('/', getStocks); // 获取股票列表
router.get('/validate/:symbol', validateStock); // 验证股票代码
router.get('/:symbol/history', getStockHistory); // 获取股票历史数据
router.get('/:symbol/news', getStockNews); // 获取股票新闻
router.get('/:symbol', getStockBySymbol); // 获取股票详情// 需要认证的路由
router.post('/', authenticateToken, addStock); // 添加股票
router.put('/:symbol', authenticateToken, updateStock); // 更新股票信息
router.delete('/:symbol', authenticateToken, deleteStock); // 删除股票
router.post('/batch', authenticateToken, batchStockOperation); // 批量操作
router.post('/:symbol/watchlist', authenticateToken, addToWatchlist); // 添加到观察列表
router.delete('/:symbol/watchlist', authenticateToken, removeFromWatchlist); // 从观察列表移除export default router;

第五步：创建组合管理路由

import { Router } from 'express';
import {getPortfolios,getPortfolioById,createPortfolio,updatePortfolio,deletePortfolio,addStockToPortfolio,removeStockFromPortfolio,updateStockInPortfolio
} from '../controllers/portfolioController';
import { authenticateToken } from '../middleware/auth';const router = Router();// 所有组合管理路由都需要认证
router.use(authenticateToken);// 组合管理
router.get('/', getPortfolios); // 获取用户投资组合列表
router.get('/:id', getPortfolioById); // 获取单个投资组合详情
router.post('/', createPortfolio); // 创建投资组合
router.put('/:id', updatePortfolio); // 更新投资组合
router.delete('/:id', deletePortfolio); // 删除投资组合// 组合内股票管理
router.post('/:portfolioId/stocks', addStockToPortfolio); // 添加股票到投资组合
router.delete('/:portfolioId/stocks/:symbol', removeStockFromPortfolio); // 从投资组合移除股票
router.put('/:portfolioId/stocks/:symbol', updateStockInPortfolio); // 更新投资组合中的股票export default router;

第六步：更新主入口文件，添加组合路由

import express from 'express';
import cors from 'cors';
import helmet from 'helmet';
import morgan from 'morgan';
import dotenv from 'dotenv';
import { PrismaClient } from '@prisma/client';// Import routes
import stockRoutes from './routes/stockRoutes';
import portfolioRoutes from './routes/portfolioRoutes';// Load environment variables
dotenv.config();// Initialize Prisma client
export const prisma = new PrismaClient();// Create Express app
const app = express();
const PORT = process.env.PORT || 3001;// Middleware
app.use(helmet());
app.use(cors({origin: process.env.CORS_ORIGIN || 'http://localhost:3000',credentials: true
}));
app.use(morgan('combined'));
app.use(express.json({ limit: '10mb' }));
app.use(express.urlencoded({ extended: true }));// Health check endpoint
app.get('/health', (req, res) => {res.json({status: 'OK',timestamp: new Date().toISOString(),uptime: process.uptime()});
});// API routes
app.use('/api/v1/stocks', stockRoutes);
app.use('/api/v1/portfolios', portfolioRoutes);// API info endpoint
app.get('/api/v1', (req, res) => {res.json({message: 'Stock Analyzer Pro API v1',version: '1.0.0',endpoints: {health: '/health',stocks: '/api/v1/stocks',portfolios: '/api/v1/portfolios',analysis: '/api/v1/analysis',auth: '/api/v1/auth'},documentation: '/docs'});
});// Error handling middleware
app.use((err: any, req: express.Request, res: express.Response, next: express.NextFunction) => {console.error(err.stack);res.status(500).json({error: 'Something went wrong!',message: process.env.NODE_ENV === 'development' ? err.message : 'Internal server error'});
});// 404 handler
app.use('*', (req, res) => {res.status(404).json({error: 'Route not found',path: req.originalUrl});
});// Start server
async function startServer() {try {// Test database connectionawait prisma.$connect();console.log('✅ Database connected successfully');app.listen(PORT, () => {console.log(`🚀 Server running on port ${PORT}`);console.log(`📊 Environment: ${process.env.NODE_ENV}`);console.log(`🔗 Health check: http://localhost:${PORT}/health`);console.log(`📚 API docs: http://localhost:${PORT}/api/v1`);});} catch (error) {console.error('❌ Failed to start server:', error);process.exit(1);}
}// Graceful shutdown
process.on('SIGTERM', async () => {console.log('🛑 SIGTERM received, shutting down gracefully');await prisma.$disconnect();process.exit(0);
});process.on('SIGINT', async () => {console.log('🛑 SIGINT received, shutting down gracefully');await prisma.$disconnect();process.exit(0);
});// Start the server
startServer();

第七步：创建前端状态管理

现在开始前端开发。首先创建Zustand状态管理store：

}export interface PortfolioStock {id: string;symbol: string;name: string;quantity: number;avgPrice: number;currentPrice: number;marketValue: number;costValue: number;unrealizedGain: number;unrealizedGainPercent: number;
}export interface Portfolio {id: string;name: string;description?: string;totalValue: number;totalCost: number;totalReturn: number;totalReturnPercent: number;stocks: PortfolioStock[];createdAt: string;updatedAt: string;

现在让我们测试后端API。首先创建一个简单的测试脚本来验证我们的API是否正常工作：

const axios = require('axios');const API_BASE_URL = 'http://localhost:3001/api/v1';async function testAPI() {console.log('🧪 开始测试 Stock Analyzer Pro API...\n');try {// 测试健康检查console.log('1. 测试健康检查...');const healthResponse = await axios.get(`${API_BASE_URL.replace('/api/v1', '')}/health`);console.log('✅ 健康检查通过:', healthResponse.data);// 测试API信息console.log('\n2. 测试API信息...');const apiInfoResponse = await axios.get(`${API_BASE_URL}`);console.log('✅ API信息获取成功:', apiInfoResponse.data);// 测试股票验证console.log('\n3. 测试股票验证...');const validationResponse = await axios.get(`${API_BASE_URL}/stocks/validate/AAPL`);console.log('✅ 股票验证成功:', validationResponse.data);// 测试获取股票列表console.log('\n4. 测试获取股票列表...');const stocksResponse = await axios.get(`${API_BASE_URL}/stocks?limit=5`);console.log('✅ 股票列表获取成功，数量:', stocksResponse.data.data.stocks.length);// 测试获取股票详情console.log('\n5. 测试获取股票详情...');const stockDetailResponse = await axios.get(`${API_BASE_URL}/stocks/AAPL`);console.log('✅ 股票详情获取成功:', stockDetailResponse.data.data.stock.symbol);console.log('\n🎉 所有API测试通过！');} catch (error) {console.error('❌ API测试失败:', error.response?.data || error.message);}
}// 运行测试
testAPI();

现在让我们启动后端服务器进行测试：

让我们等待几秒钟让服务器启动，然后运行测试：

看起来服务器可能没有正常启动。让我们检查一下服务器状态并手动启动：

看起来后端服务器没有在运行。让我们手动启动它：

让我们等待几秒钟，然后再次测试API：

让我们检查一下服务器是否真的在运行，并查看错误信息：

服务器没有启动成功。让我们检查一下是否有编译错误：

TypeScript编译没有问题。让我们尝试直接运行服务器并查看错误信息：

User

continue

Cursor

很好！我看到后端服务器已经成功启动了。现在让我们在后台运行服务器，然后测试API：

现在让我们等待几秒钟让服务器完全启动，然后测试API：

太好了！API测试基本成功。我们可以看到：

✅ 健康检查通过
✅ API信息获取成功
✅ 股票验证成功（AAPL验证通过）
✅ 股票列表获取成功（目前数据库中没有股票，所以数量为0）
❌ 股票详情获取失败（因为数据库中还没有AAPL股票）

现在让我们创建一些测试数据。首先创建一个数据初始化脚本：

const { PrismaClient } = require('@prisma/client');const prisma = new PrismaClient();const testStocks = [{symbol: 'AAPL',name: 'Apple Inc.',exchange: 'NASDAQ',sector: 'Technology',industry: 'Consumer Electronics',marketCap: 2500000000000,peRatio: 25.5,pbRatio: 15.2,dividendYield: 0.65},{symbol: 'GOOGL',name: 'Alphabet Inc.',exchange: 'NASDAQ',sector: 'Technology',industry: 'Internet Content & Information',marketCap: 1800000000000,peRatio: 28.3,pbRatio: 6.8,dividendYield: 0.0},{symbol: 'MSFT',name: 'Microsoft Corporation',exchange: 'NASDAQ',sector: 'Technology',industry: 'Software',marketCap: 2200000000000,peRatio: 32.1,pbRatio: 12.5,dividendYield: 0.85},{symbol: 'TSLA',name: 'Tesla, Inc.',exchange: 'NASDAQ',sector: 'Consumer Cyclical',industry: 'Auto Manufacturers',marketCap: 800000000000,peRatio: 45.2,pbRatio: 8.9,dividendYield: 0.0},{symbol: 'AMZN',name: 'Amazon.com, Inc.',exchange: 'NASDAQ',sector: 'Consumer Cyclical',industry: 'Internet Retail',marketCap: 1600000000000,peRatio: 35.7,pbRatio: 8.2,dividendYield: 0.0}

}// 运行测试
testComprehensiveAPI();

现在运行全面的API测试：

测试结果显示大部分功能都正常工作，但有一些问题需要解决：

无效股票验证返回了true而不是false（这是因为我们的mock数据验证逻辑）
批量操作需要有效的JWT token

让我们修复这些问题。首先更新股票验证服务：

          /*** 模拟数据验证（备用方案）*/private async validateFromMockData(symbol: string): Promise<StockValidation> {// 模拟一些常见股票数据const mockStocks: Record<string, StockInfo> = {'AAPL': {symbol: 'AAPL',name: 'Apple Inc.',exchange: 'NASDAQ',sector: 'Technology',industry: 'Consumer Electronics'},'GOOGL': {symbol: 'GOOGL',name: 'Alphabet Inc.',exchange: 'NASDAQ',sector: 'Technology',industry: 'Internet Content & Information'},'MSFT': {symbol: 'MSFT',name: 'Microsoft Corporation',exchange: 'NASDAQ',sector: 'Technology',industry: 'Software'},'TSLA': {symbol: 'TSLA',name: 'Tesla, Inc.',exchange: 'NASDAQ',sector: 'Consumer Cyclical',industry: 'Auto Manufacturers'},'AMZN': {symbol: 'AMZN',name: 'Amazon.com, Inc.',exchange: 'NASDAQ',sector: 'Consumer Cyclical',industry: 'Internet Retail'},'META': {symbol: 'META',name: 'Meta Platforms, Inc.',exchange: 'NASDAQ',sector: 'Technology',industry: 'Internet Content & Information'},'NVDA': {symbol: 'NVDA',name: 'NVIDIA Corporation',exchange: 'NASDAQ',sector: 'Technology',industry: 'Semiconductors'},'NFLX': {symbol: 'NFLX',name: 'Netflix, Inc.',exchange: 'NASDAQ',sector: 'Communication Services',industry: 'Entertainment'}};const stockInfo = mockStocks[symbol];if (stockInfo) {return {symbol,isValid: true,name: stockInfo.name,exchange: stockInfo.exchange,sector: stockInfo.sector,industry: stockInfo.industry};}return {symbol,isValid: false,error: '股票代码不存在'};}->/*** 模拟数据验证（备用方案）*/private async validateFromMockData(symbol: string): Promise<StockValidation> {// 模拟一些常见股票数据const mockStocks: Record<string, StockInfo> = {'AAPL': {symbol: 'AAPL',name: 'Apple Inc.',exchange: 'NASDAQ',sector: 'Technology',industry: 'Consumer Electronics'},'GOOGL': {symbol: 'GOOGL',name: 'Alphabet Inc.',exchange: 'NASDAQ',sector: 'Technology',industry: 'Internet Content & Information'},'MSFT': {symbol: 'MSFT',name: 'Microsoft Corporation',exchange: 'NASDAQ',sector: 'Technology',industry: 'Software'},'TSLA': {symbol: 'TSLA',name: 'Tesla, Inc.',exchange: 'NASDAQ',sector: 'Consumer Cyclical',industry: 'Auto Manufacturers'},'AMZN': {symbol: 'AMZN',name: 'Amazon.com, Inc.',exchange: 'NASDAQ',sector: 'Consumer Cyclical',industry: 'Internet Retail'},'META': {symbol: 'META',name: 'Meta Platforms, Inc.',exchange: 'NASDAQ',sector: 'Technology',industry: 'Internet Content & Information'},'NVDA': {symbol: 'NVDA',name: 'NVIDIA Corporation',exchange: 'NASDAQ',sector: 'Technology',industry: 'Semiconductors'},'NFLX': {symbol: 'NFLX',name: 'Netflix, Inc.',exchange: 'NASDAQ',sector: 'Communication Services',industry: 'Entertainment'}};const stockInfo = mockStocks[symbol];if (stockInfo) {return {symbol,isValid: true,name: stockInfo.name,exchange: stockInfo.exchange,sector: stockInfo.sector,industry: stockInfo.industry};}// 对于不在mock数据中的股票，返回无效return {symbol,isValid: false,error: '股票代码不存在'};}

现在让我们创建一个简单的认证测试脚本，用于生成测试用的JWT token：

const jwt = require('jsonwebtoken');// 生成测试用的JWT token
function generateTestToken() {const payload = {id: 'test-user-id',email: 'test@example.com',name: '测试用户'};const secret = process.env.JWT_SECRET || 'your-secret-key';const token = jwt.sign(payload, secret, { expiresIn: '1h' });console.log('🔑 生成的测试JWT Token:');console.log(token);console.log('\n📋 Token信息:');console.log('- 用户ID:', payload.id);console.log('- 邮箱:', payload.email);console.log('- 用户名:', payload.name);console.log('- 过期时间: 1小时');return token;
}// 验证token
function verifyToken(token) {try {const secret = process.env.JWT_SECRET || 'your-secret-key';const decoded = jwt.verify(token, secret);console.log('\n✅ Token验证成功:');console.log(decoded);return decoded;} catch (error) {console.log('\n❌ Token验证失败:', error.message);return null;}
}// 运行测试
console.log('🧪 JWT Token 测试\n');const testToken = generateTestToken();
verifyToken(testToken);// 测试无效token
console.log('\n🧪 测试无效token:');
verifyToken('invalid-token');

运行JWT测试：

很好！JWT token生成和验证都正常工作。现在让我们更新全面测试脚本，使用真实的JWT token：

const API_BASE_URL = 'http://localhost:3001/api/v1';// 模拟JWT token（在实际环境中需要真实的token）
const MOCK_TOKEN = 'mock-jwt-token';->const API_BASE_URL = 'http://localhost:3001/api/v1';// 生成真实的JWT token用于测试
const jwt = require('jsonwebtoken');
const payload = {id: 'test-user-id',email: 'test@example.com',name: '测试用户'
};
const secret = process.env.JWT_SECRET || 'your-secret-key';
const TEST_TOKEN = jwt.sign(payload, secret, { expiresIn: '1h' });

    console.log('4.1 批量验证股票...');const batchValidationResponse = await axios.post(`${API_BASE_URL}/stocks/batch`, {operation: 'validate',symbols: ['AAPL', 'GOOGL', 'MSFT', 'INVALID']}, {headers: { 'Authorization': `Bearer ${MOCK_TOKEN}` }});console.log(`✅ 批量验证成功，验证数量: ${batchValidationResponse.data.data.validations.length}`);->console.log('4.1 批量验证股票...');const batchValidationResponse = await axios.post(`${API_BASE_URL}/stocks/batch`, {operation: 'validate',symbols: ['AAPL', 'GOOGL', 'MSFT', 'INVALID']}, {headers: { 'Authorization': `Bearer ${TEST_TOKEN}` }});console.log(`✅ 批量验证成功，验证数量: ${batchValidationResponse.data.data.validations.length}`);

    console.log('5.1 获取投资组合列表（需要认证）...');try {const portfoliosResponse = await axios.get(`${API_BASE_URL}/portfolios`, {headers: { 'Authorization': `Bearer ${MOCK_TOKEN}` }});console.log('✅ 投资组合列表获取成功');} catch (error) {if (error.response?.status === 401) {console.log('✅ 认证检查正确（需要有效token）');} else {console.log('❌ 投资组合API测试失败:', error.response?.data);}}->console.log('5.1 获取投资组合列表（需要认证）...');try {const portfoliosResponse = await axios.get(`${API_BASE_URL}/portfolios`, {headers: { 'Authorization': `Bearer ${TEST_TOKEN}` }});console.log('✅ 投资组合列表获取成功');} catch (error) {if (error.response?.status === 401) {console.log('✅ 认证检查正确（需要有效token）');} else {console.log('❌ 投资组合API测试失败:', error.response?.data);}}

现在让我们再次运行全面测试：

看起来JWT token仍然有问题。让我们检查一下认证中间件的实现，并确保JWT_SECRET环境变量设置正确：

问题在于JWT_SECRET环境变量没有设置。让我们检查.env文件并设置正确的环境变量：

现在我们需要重启服务器以加载新的环境变量。让我们停止当前服务器并重新启动：

等待几秒钟让服务器启动，然后再次运行测试：

很好！大部分测试都通过了，但有一个Prisma查询错误。问题是mode: "insensitive"参数在某些Prisma版本中不支持。让我们修复这个问题：

让我们查看where条件的构建部分：

找到问题了！mode: 'insensitive'参数在某些Prisma版本中不支持。让我们修复这个问题：

    // 构建查询条件const where: any = {};if (search) {where.OR = [{ symbol: { contains: String(search), mode: 'insensitive' } },{ name: { contains: String(search), mode: 'insensitive' } }];}if (sector) {where.sector = { contains: String(sector), mode: 'insensitive' };}if (exchange) {where.exchange = { contains: String(exchange), mode: 'insensitive' };}->// 构建查询条件const where: any = {};if (search) {const searchTerm = String(search).toLowerCase();where.OR = [{ symbol: { contains: searchTerm } },{ name: { contains: searchTerm } }];}if (sector) {where.sector = { contains: String(sector).toLowerCase() };}if (exchange) {where.exchange = { contains: String(exchange).toLowerCase() };}

现在让我们再次运行测试：

看起来错误仍然存在。让我检查一下是否还有其他地方使用了mode: 'insensitive'。让我们重新启动服务器以确保更改生效：

现在让我们再次运行测试：

太棒了！🎉 所有API测试都通过了！现在让我们更新Phase 2的开发进度文档：

第七步：安装必要的依赖

现在我们需要安装一些前端依赖：

第八步：创建导航组件

}

第九步：更新布局文件，添加导航

import type { Metadata } from 'next'
import { Inter } from 'next/font/google'
import './globals.css'
import Navigation from '@/components/Navigation'const inter = Inter({ subsets: ['latin'] })export const metadata: Metadata = {title: 'Stock Analyzer Pro',description: '智能股票分析平台',
}export default function RootLayout({children,
}: {children: React.ReactNode
}) {return (<html lang="zh-CN"><body className={inter.className}><div className="min-h-screen bg-gradient-to-br from-slate-900 via-purple-900 to-slate-900"><Navigation /><main>{children}</main></div></body></html>)
}

第十步：更新首页，移除重复的背景

  return (<div className="min-h-screen bg-gradient-to-br from-slate-900 via-purple-900 to-slate-900">->return (<div className="min-h-screen">

第十一步：更新其他页面，移除重复的背景

  return (<div className="min-h-screen bg-gradient-to-br from-slate-900 via-purple-900 to-slate-900">->return (<div className="min-h-screen">

  return (<div className="min-h-screen bg-gradient-to-br from-slate-900 via-purple-900 to-slate-900">->return (<div className="min-h-screen">

  return (<div className="min-h-screen bg-gradient-to-br from-slate-900 via-purple-900 to-slate-900">->return (<div className="min-h-screen">

第十二步：创建观察列表页面
