Set-Cookie头不设置cookie跨域。 Cookie未保存

Question

我正在尝试执行跨域请求。看起来所有的标题都可以。但是cookie没有设置，我不知道为什么。这可能是因为401服务器状态（无法访问更改服务器）还是因为请求是从http到https服务器？

这些是标头：

Request URL:https://domain/current-user 
Request Method:GET 
Status Code:401 Unauthorized

尝试在该请求设置withCredentials，例如

var xhr = new XMLHttpRequest(); 
xhr.withCredentials = true;
