React后台管理系统-ajax请求封装

Posted 2020-11-20 giser123

1.新建文件夹 util , 在util里边新建 mm.jsx文件

2.使用jquery里边的ajax发送请求，回调用promise,返回一个promise对象

1. request(param){
2.         return new Promise((resolve, reject) => {
3.             $.ajax({
4.                 type : param.type || ‘get‘,
5.                 url : param.url || ‘‘,
6.                 dataType : param.dataType || ‘json‘,
7.                 data : param.data || null,
8.                 success : res => {
9.                     // 数据请求成功
10.                     if(0 === res.status){
11.                         typeof resolve === ‘function‘ && resolve(res.data, res.msg);
12.                     }
13.                     // 没有登录状态，强制登录
14.                     else if(10 === res.status){
15.                         this.doLogin();
16.                     }
17.                     else{
18.                         typeof reject === ‘function‘ && reject(res.msg || res.data);
19.                     }
20.                 },
21.                 error : err => {
22.                     typeof reject === ‘function‘ && reject(err.statusText);
23.                 }
24.             });
25.         });
26.     }

3.页面引入

1. const _mm = new MUtil();

4.使用，传入参数

1. // 首页数据统计
2.    getHomeCount(){
3.        return _mm.request({
4.            url: ‘/manage/statistic/base_count.do‘
5.        });
6.    }
