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>
