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。
