2、vue.config.js 代理配置


devServer: {
 
 //跨域
 
 port: 9528, // 端口号
 
 open: true, //配置自动启动浏览器
 
 proxy: {
 
  // 配置跨域处理 可以设置多个
 
  '^/api': {
 
  target: 'https://www.weixinyue.cn',
 
  changeOrigin: true,
 
  pathRewrite: {
 
   '^/api': '' // 规定请求地址以什么作为开头
 
  },
 
  logLevel:'debug'
 
   
 
  },
 
  '^/test': {
 
  target: 'https://www.weixinyue.cn',
 
  changeOrigin: true,
 
  pathRewrite: {
 
   '^/test': '' // 规定请求地址以什么作为开头
 
  },
 
  logLevel:'debug'
 
   
 
  },
 
  '^/pro': {
 
  target: 'https://www.weixinyue.cn',
 
  changeOrigin: true,
 
  pathRewrite: {
 
   '^/pro': '' // 规定请求地址以什么作为开头
 
  },
 
  logLevel:'debug'
 
   
 
  }
 
 }
 
 }



3、package.json 配置　


"scripts": {
 
 "dev": "npm run serve",
 
 "serve": "vue-cli-service serve --mode development",
 
 "test": "vue-cli-service serve --mode test",
 
 "pro": "vue-cli-service serve --mode production",
 
 "build": "vue-cli-service build",
 
 "lint": "vue-cli-service lint"
 
 },


4、.eslintrc.js 配置


module.exports = {
 
 root: true,
 
 env: {
 
 node: true
 
 },
 
 extends: [
 
 'plugin:vue/essential'
 
 // '@vue/standard'
 
 ],
 
 parserOptions: {
 
 parser: 'babel-eslint'
 
 },
 
 rules: {
 
 'no-console': process.env.NODE_ENV === 'production' "color: #ff0000">本章节总结：


讲述基于vue/cli，项目的基础搭建。
1、跨域配置
2、axios请求封装
3、eslint配置
4、环境dev,test，pro（开发，测试，线上），run自动调用对应的接口（proxy多代理配置）
