关于withCredentials与状态码204

The value of the ‘Access-Control-Allow-Origin’ header in the response must not be the wildcard ‘*’ when the request’s credentials mode is ‘include’. Origin ‘’ is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

http状态码变成产生204，前端报这个错误，解决方案有两个：
1.把withCredentials设置为false，不允许cookie
2.配置withCredentials=true, 后端需配置Access-Control-Allow-Credentials，Access-Control-Allow-Origin不能为*, 必须是地址
