react（axios）拦截器的简单配置

import React from ‘react’;
import axios from ‘axios’;
import {BrowserRouter as Router} from ‘react-router-dom’
import {baseLocalUrl} from ‘…/server’
import qs from ‘qs’

// 添加一个请求的拦截
axios.interceptors.request.use((config) => {
//1抓取本地token，携带在请求头里
let user = window.localStorage.getItem(‘user’);
user = user ? qs.parse(user) : ‘’;
config.headers={‘token’: user.token}

//显示loading…

return config;//2返回请求

}, function(error) {
// 请求错误时做点事
return Promise.reject(error);
});

//添加一个响应拦截
axios.interceptors.response.use(function(response) {
console.log(‘响应拦截’,response);

let router=new Router();
//token过期: 返回值2,当前路由不是login时跳转
if (response.data.err === 2 && !router.history.location.pathname.includes(’/login’)) {
console.log(‘token 失败 跳转到login’,router);
window.location.href=baseLocalUrl+’/login?path=’+router.history.location.pathname

/*router.history.push({  //hash 模式可以，history模式有问题
  pathname: '/login',
  search: "path="+router.history.location.pathname
})*/

}
return response;

}, function(error) {

return Promise.reject(error);
});

React.axios = axios;//axios绑到对象包上
React.Component.prototype.axios = axios; // axios绑定到Component类的原型 组件|this.axios
window.axios = axios; //× 希望全局使用axios , 使用webpack 来配置
export default axios;
