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>
