http请求的代码如下:
import axios from ‘axios‘ import { Message} from ‘element-ui‘ import store from ‘../store‘ //vuex import { getToken } from ‘@/utils/auth‘ //token // 创建axios实例 const service = axios.create({ //baseURL: "https://www.cnblogs.com", // api的base_url timeout: 5000 // 请求超时时间 }) //http request 拦截器 service.interceptors.request.use( config => { config.headers = { ‘Content-Type‘:‘application/x-www-form-urlencoded‘, ‘X-Token‘:getToken() } if(store.state.neddloding==0){ //等于0打开loading store.commit(‘gbfullscreenLoading‘) } store.commit(‘show‘)//每开始一次请求neddloding加一 console.log(store.state.neddloding) return config; }, error => { return Promise.reject(err); } ); //响应拦截器即异常处理 service.interceptors.response.use(response => { console.log(response) //store.commit(‘gbfullscreenLoadinga‘) //hide() return response }, err => { if (err && err.response) { switch (err.response.status) { case 400: //console.log(‘错误请求‘) Message({message: ‘错误请求‘, type: ‘error‘}); break; case 401: console.log(‘未授权,请重新登录‘) break; case 403: console.log(‘拒绝访问‘) break; case 404: console.log(‘请求错误,未找到该资源‘) break; case 405: console.log(‘请求方法未允许‘) break; case 408: console.log(‘请求超时‘) break; case 500: console.log(‘服务器端出错‘) break; case 501: console.log(‘网络未实现‘) break; case 502: console.log(‘网络错误‘) break; case 503: console.log(‘服务不可用‘) break; case 504: console.log(‘网络超时‘) break; case 505: console.log(‘http版本不支持该请求‘) break; default: console.log(`连接错误${err.response.status}`) } } else { console.log(‘连接到服务器失败‘) } return Promise.resolve(err.response) }) var that=this; function fromdata(type, url, data) { return new Promise((reslove, reject) => { service({ method: type, url: url, data: data //java后台用qs转 }) .then(res => { // store.commit(‘UPDATE_LOADING‘, false); //隐藏loading //这里可以添加指定对应状态码的处理方式,比如登陆过期,res.data.code === ‘6666‘ 路由跳转到login if(res.data.code==0){ reslove(res); console.log(store.state.neddloding) store.commit(‘hide‘) //每完成一次请求减一 if(store.state.neddloding==0){ //等于0关闭loding console.log(store.state.neddloding) store.commit(‘gbfullscreenLoadinga‘) } }else{ console.log(res.data.message) console.log(res) Message({message: ‘错误请求‘, type: ‘error‘}); } }) .catch(err => { //store.commit(‘UPDATE_LOADING‘, false); //隐藏loading reject(err.message); Message({message: ‘错误请求‘, type: ‘error‘}); //Message.error(e.message); }); }); } export default fromdata
store代码
import Vue from ‘vue‘ import Vuex from ‘vuex‘ Vue.use(Vuex) var state={ fullscreenLoading:true,//设置loading是否显示 neddloding:0//根据是否为0来判断是否关闭loading } var mutations={ gbfullscreenLoading(state){ state.fullscreenLoading=true;//loading显示 }, gbfullscreenLoadinga(state){ state.fullscreenLoading=false;//loading关闭 }, show(state){//每请求一次加一 state.neddloding++ }, hide(state){//每完成请求一次减一 state.neddloding-- } } export default new Vuex.Store({ state, mutations })
app.vue中设置loading
<template> <div id="app" v-loading.fullscreen.lock="fullscreenLoading"> <router-view></router-view> </div> </template> <script> export default { computed:{ fullscreenLoading(){ return this.$store.state.fullscreenLoading } } } </script>
