axios带有请求拦截器,避免在每个请求里面加loading重复操作,可以封装进去,在请求开始时加载loading层,请求结束关闭,loading层用vux的loading加载
axios.js
import axios from 'axios' import Vue from 'vue' // 超时时间 axios.defaults.timeout = 15000; // axios.defaults.withCredentials=true; // http请求拦截器 axios.interceptors.request.use(config => { Vue.$vux.loading.show({ text: 'Loading' }) return config }, error => { setTimeout(() => { Vue.$vux.loading.hide(); Vue.$vux.toast.text('加载超时', 'middle') },3000) return Promise.reject(error) }) // http响应拦截器 axios.interceptors.response.use(data => {// 响应成功关闭loading Vue.$vux.loading.hide() return data }, error => { setTimeout(() => { Vue.$vux.loading.hide() Vue.$vux.toast.text('请求失败', 'middle') },1000) return Promise.reject(error) }) export default axios;
封装get和post方法 axios.service.js
import axios from './axios'; class myAxios{ getUrl(url){ return `${__ce.baseURL}${url}`; // 打包时用这个 __ce.baseURL // return `/api${url}`; // 防止跨域,开发环境用这个代理 }; //公共ajax; postServer(opt) { let data = {}; if (opt.data) { data = opt.data; } axios.post(opt.url, data).then((response) => { console.log(response); if(!response.data.status){ return; } if (opt.onSuccess) { opt.onSuccess(response); } }).catch(error => { if (opt.onFailed) { opt.onFailed(error); } }); } // get 请求 getServer(opt) { let data = {}; if (opt.data) { data = opt.data; } axios.get(opt.url, {params: data}).then((response) => { if (opt.onSuccess) { opt.onSuccess(response); } }).catch(error => { if (opt.onFailed) { opt.onFailed(error); } }); } setData(opt) { let data = {}; if (opt.data) { data = opt.data; } return data; } } export default myAxios;
封装方法~
import myAxios from './axios.service' const myAxiosMethods = new myAxios(); class RecordServer{ // 查询订单 -- post方法 sendMiceIndentSearchServer(opt){ const data = myAxiosMethods.setData(opt); const url = myAxiosMethods.getUrl('/search');// 这里的/search是后端给的接口地址 myAxiosMethods.postServer({url, data, onSuccess: opt.onSuccess, onFailed: opt.onFailed}); } export default RecordServer;
在页面中使用
const recordSever = new RecordServer()
methods:{ _sendSearchServer(){ // 在需要的地方调用这个方法 recordServer.sendSearchServer({ data: this.params, // params是这个接口需要传递给后台的参数 onSuccess: (res) => { console.log(res) }, onFailed: (err) => { console.log(err) } }) } }
