vue axios 给生产环境和发布环境配置不同的接口地址(推荐)

// 配置API接口地址 var root = process.env.API // 引用axios var axios = require('axios') // 自定义判断元素类型JS function toType (obj) {  return ({}).toString.call(obj).match(//s([a-zA-Z]+)/)[1].toLowerCase() } // 参数过滤函数 function filterNull (o) {  for (var key in o) {  if (o[key] === null) {   delete o[key]  }  if (toType(o[key]) === 'string') {   o[key] = o[key].trim()  } else if (toType(o[key]) === 'object') {   o[key] = filterNull(o[key])  } else if (toType(o[key]) === 'array') {   o[key] = filterNull(o[key])  }  }  return o } function apiAxios (method, url, params, success, failure) {  if (params) {  params = filterNull(params)  }  axios({  method: method,  url: url,  data: method === 'POST' ? params : null,  params: method === 'GET' ? params : null,  baseURL: root,  withCredentials: false  })  .then(function (res) {  console.log(res);  return;  if (res.data.success === true) {   if (success) {   success(res.data)   }  } else {   if (failure) {   failure(res.data)   } else {   window.alert('error: ' + JSON.stringify(res.data))   }  }  })  .catch(function (err) {  let res = err.response  if (err) {   window.alert('api error, HTTP CODE: ' + res.status)   return  }  }) } // 返回在vue模板中的调用接口 export default {  get: function (url, params, success, failure) {  return apiAxios('GET', url, params, success, failure)  },  post: function (url, params, success, failure) {  return apiAxios('POST', url, params, success, failure)  } } 

export default {   created(){   this.$http.post('Web/test',null, res => {   console.log(res)   })  } }
