前端配置
axios默认发送请求是不携带cookie的，所以需要加上下面这句 axios.defaults.withCredentials = true;
import axios from 'axios';
axios.defaults.withCredentials = true; // 允许携带cookie
// 创建axios实例
const service = axios.create({
baseURL: process.env.VUE_APP_API_SERVER_ADDRESS,
timeout: Config.timeout, // 请求超时时间
});后端允许跨域处理配置(Springboot2.x 如果是1.x，翻一翻我其他的文章。)
Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: http://localhost:8080 //这里不能用*，需要动态设置为请求头中的地址
