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>
