spring boot +vue + axios session不一致问题的解决方案

前段配置

main.js 的配置

import axios from 'axios' axios.defaults.withCredentials = true

后端的配置

添加过滤器

- response.setHeader("Access-Control-Allow-Credentials","true"); 必须设置为true

@Component public class CorsFilter implements Filter { @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletResponse response = (HttpServletResponse) res; response.setHeader("Access-Control-Allow-Origin", "http://localhost:8080"); response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE"); response.setHeader("Access-Control-Max-Age", "3600"); response.setHeader("Access-Control-Allow-Headers", "Content-type"); response.setHeader("Access-Control-Allow-Credentials","true"); System.out.println("*********************************过滤器被使用**************************"); chain.doFilter(req, res); } }
