axios常用拦截器配置

import axios from "axios";//axios引入
import { Message } from "element-ui";//message组件引入
import router from "../router";//路由

// 创建axios实例
const service = axios.create({
  baseURL: ‘http://ip:port‘, //IP+端口
  // baseURL: process.env.VUE_APP_BASE_API, // url = base url + request url  多环境开发推荐
  // withCredentials: true, // send cookies when cross-domain requests
  timeout: 5000 // request 超时
});

// request拦截器
service.interceptors.request.use(
  (config) => {
    // do something before request is sent

    //   // let each request carry token
    //   // [‘X-Token‘] is a custom headers key
    //   // please modify it according to the actual situation
    //   config.headers[‘X-Token‘] = getToken()
    // }
    //添加token请求头
