详解vue axios二次封装

这段时间告诉项目需要，用到了vue。

刚开始搭框架的时候用的是vue-resource后面看到官方推荐axios就换过来了 顺便封装了一下

定义公共参数与引入组件：

import axios from \'axios\'
import qs from \'qs\'
 
axios.interceptors.request.use(config => {
  //显示loading
 return config
}, error => {
 return Promise.reject(error)
})
 
 
axios.interceptors.response.use(response => {
 return response
}, error => {
 return Promise.resolve(error.response)
})
 
function errorState(response) {
  //隐藏loading
 console.log(response)
 // 如果http状态码正常，则直接返回数据
 if (response && (response.status === 200 || response.status === 304 || response.status === 400)) {
  return response
   // 如果不需要除了data之外的数据，可以直接 return response.data
 }else{
  Vue.prototype.$msg.alert.show({
      title: \'提示\',
      content: \'网络异常\'
  })
 }
 
}
 
function successState(res) {
  //隐藏loading
 //统一判断后端返回的错误码
 if(res.data.errCode == \'000002\'){
    Vue.prototype.$msg.alert.show({
      title: \'提示\',
      content: res.data.errDesc||\'网络异常\',
      onShow () {
      },
      onHide () {
       console.log(\'确定\')
      }
    })
 }else if(res.data.errCode != \'000002\'&&res.data.errCode != \'000000\') {
   Vue.prototype.$msg.alert.show({
      title: \'提示\',
      content: res.data.errDesc||\'网络异常\',
      onShow () {
 
      },
      onHide () {
       console.log(\'确定\')
      }
    })
 }
}
const httpServer = (opts, data) => {
 
  let Public = { //公共参数
   \'srAppid\': \"\"
  }
 
  let httpDefaultOpts = { //http默认配置
     method:opts.method,
     baseURL,
     url: opts.url,
     timeout: 10000,
     params:Object.assign(Public, data),
     data:qs.stringify(Object.assign(Public, data)),
     headers: opts.method==\'get\'?{
      \'X-Requested-With\': \'XMLHttpRequest\',
      \"Accept\": \"application/json\",
      \"Content-Type\": \"application/json; charset=UTF-8\"
     }:{
      \'X-Requested-With\': \'XMLHttpRequest\',
      \'Content-Type\': \'application/x-www-form-urlencoded; charset=UTF-8\'
     }
  }
 
  if(opts.method==\'get\'){
   delete httpDefaultOpts.data
  }else{
   delete httpDefaultOpts.params
  }
  
  let promise = new Promise(function(resolve, reject) {
   axios(httpDefaultOpts).then(
    (res) => {
     successState(res)
     resolve(res)
    }
   ).catch(
    (response) => {
     errorState(response)
     reject(response)
    }
   )
 
  })
 return promise
}
 
export default httpServer

封装理由：

1、可以和后端商量好错误码在这统一提示统一处理，省去不必要的麻烦

2、如果做接口全报文加解密都可以在此处理

接口统一归类：

const serviceModule = {
 getLocation: {
  url: \' service/location/transfor\',
  method: \'get\'
 }
}
const ApiSetting = {...serviceModule }
 
export default ApiSetting

归类好处:

1、后期接口升级或者接口名更改便于维护

http调用：

<script>
import http from \"../../lib/http.js\";
import ApiSetting from \"../../lib/ApiSetting.js\";
export default {
 created: function() {
  http(ApiSetting.getLocation,{\"srChannel\": \"h5\",})
  .then((res)=>{
   console.log(res)
  },(error)=>{
   console.log(error)	
  })
  },
 methods: {
 
 }
}
</script>
