这是设置cookie的代码：

public HttpResponseMessage LogIn(UserLoginVM user)
{
    // Do login stuff

    var cookie = new CookieHeaderValue("STUPID-COOKIE","12345");
    cookie.Domain = Request.RequestUri.Host;
    cookie.Path = "/";
    cookie.HttpOnly = true;

    // Get user's profile

    HttpResponseMessage res = Request.CreateResponse<UserProfileVM>(HttpStatusCode.OK,profile);
    res.Headers.AddCookies(new CookieHeaderValue[] { cookie });

    return res;
}

服务器的响应如下：

HTTP/1.1 200 OK
Cache-Control: no-cache
Pragma: no-cache
Content-Type: application/json; charset=utf-8
Expires: -1

请注意以下标题：

Set-Cookie: STUPID-COOKIE=12345; domain=localhost; path=/; httponly

但是,当我在Chrome中的“资源”标签中的“Cookie”下,没有设置任何内容.此外,当我向服务器发送请求时,标题中没有cookie.

这是读取cookie的代码：

CookieHeaderValue cookie = Request.Headers.GetCookies("STUPID-COOKIE").FirstOrDefault();

cookie变量始终为null.

我的应用程序在http://localhost:53998上运行,身份验证服务在http://localhost:60858上运行

我的Chrome版本是40.0.2214.111.

编辑：这似乎与Chrome不具体.这对FireFox(v35)也不起作用. GIF：http://i.imgur.com/ZewnEtc.gif
