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": {
   "^/": "/"
  }
 }
}
