1. 配置响应拦截器

import axios from 'axios';const myAxios = axios.create({baseURL: 'http://localhost:8080/api/',
});myAxios.defaults.withCredentials = true;// 请求拦截器
myAxios.interceptors.request.use(function (config) {// Do something before request is sentconsole.log("发送请求啦...");return config;
}, function (error) {// Do something with request errorreturn Promise.reject(error);
});// 响应拦截器
myAxios.interceptors.response.use(function (response) {// Do something with response dataconsole.log("接收到请求啦...");return response.data;
}, function (error) {// Do something with response errorreturn Promise.reject(error);
});export default myAxios;

2. 强制跳转到登录页面

• 有些页面只允许用户登录后查看
• 未登录用户没有权限，后端返回 40100
• 前端接收到 40100 则跳转到登录页面，要求用户进行登录

// 响应拦截器
myAxios.interceptors.response.use(function (response) {// Do something with response dataconsole.log("接收到请求啦...");// 未登录，强制跳转到登录页if (response?.data?.code === 40100) {const redirectUrl = window.location.href;window.location.href = `/user/login?redirect${redirectUrl}`;}return response.data;
}, function (error) {// Do something with response errorreturn Promise.reject(error);
});export default myAxios;

3. 登录成功跳转到登录之前的页面

• 记录当前页面，拼接到 url 的 redirect 后面

• 登录成功，取出 redirect，重定向到 redirect

// 提交登录表单信息
const onSubmit = async (values) => {const res = await myAxios.post('/user/login', {userAccount: userAccount.value,userPassword: userPassword.value,})console.log(res, "用户登录");if (res.code === 0 && res.data) {// 返回到之前的页面const redirectUrl = route.query?.redirect as string ?? '/';window.location.href=redirectUrl;} else {Toast.fail("登录失败");}
};
