關於withCredentials與狀態碼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狀態碼變成產生204，前端報這個錯誤，解決方案有兩個：
1.把withCredentials設置爲false，不允許cookie
2.配置withCredentials=true, 後端需配置Access-Control-Allow-Credentials，Access-Control-Allow-Origin不能爲*, 必須是地址
