axios 实现 无感刷新方案

import axios from "axios";
import { refreshToken } from "../api/index"; //刷新token的api
let isRefreshToken = false; //是否正在进行刷新token
let requestList = []; // 请求队列const request = axios.create({baseURL: "/api",timeout: 10000,
});// 请求拦截器
request.interceptors.request.use((config) => {let headerToken = localStorage.getItem("acc_token");// 设置请求头config.headers.Authorization = `Bearer ${headerToken}`;return config;},(error) => {// 请求错误时做些事return Promise.reject(error);}
);// 响应拦截器
request.interceptors.response.use(async (response) => {// 401 代表token过期，需要刷新tokenif (response.data.code == 401) {// 这里可以加入判断，判断 refreshToken 也过期了，直接 router.push 回登录页// if () {// router.push('/login')// }if (!isRefreshToken) {isRefreshToken = true;let res = await refreshToken(); // 刷新 token 的接口isRefreshToken = false;localStorage.setItem("acc_token", res.data.accToken);//   重发请求队列请求requestList.forEach((callback) => {callback();});requestList = [];let currentRequest = await request(response.config);return currentRequest;} else {// 将并发的请求，通过回调函数暂存起来，当token 刷新之后，在进行请求return new Promise((resolve) => {requestList.push(() => {resolve(request(response.config));});});}}return response;},(error) => {return Promise.reject(error);}
);export default request;
