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 sent
    console.log("发送请求啦...");
    return config;
}, function (error) {
    // Do something with request error
    return Promise.reject(error);
});

// 响应拦截器
myAxios.interceptors.response.use(function (response) {
    // Do something with response data
    console.log("接收到请求啦...");
    return response.data;
}, function (error) {
    // Do something with response error
    return 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 data
    console.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 error
    return 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");
  }
};
