webpack配置代理,解决跨域

在config文件夹中的index.js文件配置

主要是这句话

proxyTable: { //本地测试接口      '/': {         target: 'http://xx.xx.xx.xx',         changeOrigin: true,         secure: false     } },

示例代码：

module.exports = {  dev: {     // Paths    assetsSubDirectory: 'static',    assetsPublicPath: '/',    proxyTable: { //本地测试接口      '/': {         target: 'http://xx.xx.xx.xx',         changeOrigin: true,         secure: false       }     },     // 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  }}

vue跨域问题,修改代理后仍404

首先确认安装了axios，安装方法：cnpm install axios -S或者不用镜像npm install axios

dev: {undefined

// PathsassetsSubDirectory: 'static',assetsPublicPath: '/',proxyTable: {  '/api': {    target: 'http://40.73.37.92:8090/',//设置你调用的接口域名和端口号 别忘了加http    changeOrigin: true,    pathRewrite: {      '^/api': ''//这里理解成用'/api'代替target里面的地址，后面组件中我们掉接口时直接用api代替 比如我要调用'http://40.00.100.100:3002/user/add'，直接写'/api/user/add'即可    }  }},
