详解vue+axios给开发环境和生产环境配置不同的接口地址

//检查某个文件是否存在try { fs.statSync(path.join(__dirname, '../proxy/' + templatedir + '.json')) //如果可以执行到这里那么就表示存在了 console.log(124) proxyTable = require('../proxy/' + templatedir + '.json')} catch (e) { //捕获异常'}module.exports = { dev: {  // Paths  assetsSubDirectory: 'static',  assetsPublicPath: '/',  proxyTable: proxyTable,  // Various Dev Server settings  host: 'localhost', // can be overwritten by process.env.HOST  index: templatedir,  port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined}

{ "/": {  "target": "", // 被请求的地址  "changeOrigin": true,  "pathRewrite": {   "^/": "/"  } }}
