本文介绍了一个Vue项目的配置文件，详细解释了如何通过设置代理表来实现本地开发环境与线上环境的域名一致，以便进行跨域请求。同时给出了具体的配置代码示例。

本来我是不想写的，但为了加深印象还是写一写吧。

./config/index.js

module.exports = {
  dev: {

    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {
        '/api': {  //使用"/api"来代替"http://charon-satellite.com" 
            target: 'http://xxx.charon-satellite.com', //源地址 
            secure: false,  // 如果是https接口，需要配置这个参数
            changeOrigin: true, //改变源 
            pathRewrite: { 
              '^/api': '' //路径重写 
            } 
        } 
    },

    // Various Dev Server settings
    host: 'localhost', // can be overwritten by process.env.HOST
    port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
    autoOpenBrowser: false,
    errorOverlay: true,
    notifyOnErrors: true,
    poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-

    
    /**
     * Source Maps
     */

    // https://webpack.js.org/configuration/devtool/#development
    devtool: 'cheap-module-eval-source-map',

    // If you have problems debugging vue-files in devtools,
    // set this to false - it *may* help
    // https://vue-loader.vuejs.org/en/options.html#cachebusting
    cacheBusting: true,

    cssSourceMap: true
  },

  build: {
    // Template for index.html
    index: path.resolve(__dirname, '../dist/index.html'),

    // Paths
    assetsRoot: path.resolve(__dirname, '../dist'),
    assetsSubDirectory: 'static',
    assetsPublicPath: './',

    /**
     * Source Maps
     */

    productionSourceMap: true,
    // https://webpack.js.org/configuration/devtool/#production
    devtool: '#source-map',

    // Gzip off by default as many popular static hosts such as
    // Surge or Netlify already gzip all static assets for you.
    // Before setting to `true`, make sure to:
    // npm install --save-dev compression-webpack-plugin
    productionGzip: false,
    productionGzipExtensions: ['js', 'css'],

    // Run the build command with an extra argument to
    // View the bundle analyzer report after build finishes:
    // `npm run build --report`
    // Set to `true` or `false` to always turn it on or off
    bundleAnalyzerReport: process.env.npm_config_report
  }
}

./api.js (管理接口的JS文件)

...
// export const base = 'http://xxx.charon-satellite.com'; // 线上
export const base = '/api';  // 本地
export const qs = require('qs')

// public
export const login = base + '/xxx/xxx/dologin'; // 登录
...

原理：简单的说就是利用了vue所用的node.js服务器环境，建立代理服务器，使本地的域名与线上域名相同。
