前端开发提效工具——用户自定义代码片段
做开发总是会有大量的代码要写，但是有时候某些代码是非常基础但是很多，我们就可以把这一部分整合起来，使用一个很简短的关键字来快速唤出。
如何新建这样的代码段？
1.在VSCode当中找到Snippets，然后点击
2.之后会弹出一个框，选择New Global Snippets file
3.弹出一个小框，你在这里书写该自定义代码片段的名称，记得复制下来
4.然后进入具体的文件，就像下面这样
默认模板如下：
{// Place your global snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope // is left empty or omitted, the snippet gets applied to all languages. The prefix is what is // used to trigger the snippet and the body will be expanded and inserted. Possible variables are: // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. // Placeholders with the same ids are connected.// Example:// "Print to console": {// "scope": "javascript,typescript",// "prefix": "log",// "body": [// "console.log('$1');",// "$2"// ],// "description": "Log output to console"// }

自定义axios拦截器并封装
{ // 代码片段的名称，这个名称会显示在代码片段列表中 "axiost": { "prefix": "axiost", // 触发代码片段的关键字 "body": [ "import axios, { AxiosInstance, InternalAxiosRequestConfig } from 'axios';", "", "const creatAxios = (config?: InternalAxiosRequestConfig) => {", "\tconsole.log('打印配置信息', import.meta.env);", "\tconst instance: AxiosInstance = axios.create({", "\t\tbaseURL: import.meta.env.VITE_API_BASE_URL,", "\t\ttimeout: import.meta.env.VITE_TIMEOUT,", "\t\twithCredentials: true, // default-false 跨域请求是否需要凭证", "\t\theaders: {", "\t\t\t'Content-Type': 'application/json',", "\t\t\tAccept: 'application/json',", "\t\t},", "\t\t...config,", "\t});", "", "\t// 重写请求拦截器规则", "\tinstance.interceptors.request.use(", "\t\t(config: InternalAxiosRequestConfig) => {", "\t\t\t// 在发送请求之前做些什么", "\t\t\tconsole.log('在发送请求之前做些什么呢？');", "\t\t\treturn config;", "\t\t},", "\t\t(error: any) => {", "\t\t\t// 对请求错误做些什么", "\t\t\tconsole.log('对请求错误做些什么呢？');", "\t\t\treturn Promise.reject(error);", "\t\t},", "\t);", "", "\t// 重写响应拦截器规则", "\tinstance.interceptors.response.use(", "\t\t(response: any) => {", "\t\t\t// 对响应数据做点什么", "\t\t\tconsole.log('对响应数据做点什么呢？', response.data.msg);", "\t\t\tif (response.data.code !== 200) {", "\t\t\t\tconsole.error(response.data.msg);", "\t\t\t} else {", "\t\t\t\tconsole.log(response.data.msg);", "\t\t\t}", "\t\t\treturn response;", "\t\t},", "\t\t(error: any) => {", "\t\t\t// 对响应错误做点什么", "\t\t\tconsole.log('对响应错误做点什么呢？', error);", "\t\t\treturn Promise.reject(error);", "\t\t},", "\t);", "", "\treturn instance;", "};" ], "description": "快速生成一个创建Axios实例的函数" }
}在html引入echarts
{// Place your global snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope // is left empty or omitted, the snippet gets applied to all languages. The prefix is what is // used to trigger the snippet and the body will be expanded and inserted. Possible variables are: // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. // Placeholders with the same ids are connected.// Example:"echartsUrl": {"scope": "javascript,typescript,html","prefix": "echartsUrl","body": ["<script src=\"https://cdn.jsdelivr.net/npm/echarts/dist/echarts.min.js\"></script>"],"description": "Log output to console"}
}html板子（这个其实你输入感叹号也可以实现）
{ // 这里是文件的全局描述，不是必须的，但有助于理解 "HTML Templates": { // 定义一个前缀，当在HTML文件中输入此前缀并按下Tab时，将展开此片段 "Print to console": { "prefix": "htmlt", // 描述（可选） "description": "Log output to console", // 片段内容 "body": [ "<!DOCTYPE html>", "<html lang=\"en\">", "<head>", " <meta charset=\"UTF-8\">", " <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">", " <title>Document</title>", "</head>", "<body>", " <h1>Hello, World!</h1>", " <!-- Your HTML content goes here -->", "</body>", "</html>" ] } }
}html表的模板
{// Place your global snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope // is left empty or omitted, the snippet gets applied to all languages.

}最后想说的
代码片段只是提效的手段，作为程序员应该发挥想象力。我这里只是抛砖引玉，介绍一下我的提效方式，你完全可以根据自身特点利用这个功能来做自己的片段！！！
