我想使用HttpOnlycookie，我在 Java 中设置如下：
...
Cookie accessTokenCookie = new Cookie("token", userToken);
accessTokenCookie.setHttpOnly(true);
accessTokenCookie.setSecure(true);
accessTokenCookie.setPath("/");
response.addCookie(accessTokenCookie);
Cookie refreshTokenCookie = new Cookie("refreshToken", refreshToken);
refreshTokenCookie.setHttpOnly(true);
refreshTokenCookie.setSecure(true);
refreshTokenCookie.setPath("/");
response.addCookie(refreshTokenCookie);
...
我得到了带有 cookie 的客户端响应，但是当我发送下一个请求时，我的请求中没有 cookie。也许我错过了一些东西，但据我所知，HttpOnly浏览器必须在每个到达定义路径的请求（JavaScript 无权访问这些 cookie）时将这些 cookie 发送回。
我有以下请求标头：
Accept:application/json, text/plain, */*
Accept-Encoding:gzip, deflate, br
Accept-Language:en-US,en;q=0.8,hu;q=0.6,ro;q=0.4,fr;q=0.2,de;q=0.2

X-Requested-With:XMLHttpRequest
以及以下响应标头：
Access-Control-Allow-Credentials:true
Access-Control-Allow-Origin:http://localhost:4200
Access-Control-Expose-Headers:Access-Control-Allow-Origin, Content-Type, Date, Link, Server, X-Application-Context, X-Total-Count

Set-Cookie:refreshToken=eyJhb8w;Max-Age=10000;path=/;Secure;HttpOnly
Vary:Origin
同样在客户端，我withCredentials: true在 Angular2 中使用并X-Requested-With:XMLHttpRequest作为请求标头。
而且是跨域。
