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) 
  }) 
 } 
}
