c# - HttpClient 不在 CookieContainer 中存储 cookie

Question

我正在使用 VS2010 +.NET 4.0 + System.Net.Http(来自 Nuget) .

由于我无法理解的原因，我在 HttpResponseMessage 中收到的 session cookie 不会自动保存在 HttpClient CookieContainer 中。这是我的代码的样子:

CookieContainer cookies = new CookieContainer();
HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = cookies;
HttpClient client = new HttpClient(handler);

Uri site = new Uri("https://www.mywebsite.com");
var response1 = client.SendAsync(new HttpRequestMessage(HttpMethod.Get,site)).Result;

我可以在响应 header 中看到以下内容:

Set-Cookie: JSESSIONID=FC8110E434C2C6DAB78B4E335024A639; Path=/member; Secure

但是我的 cookie 容器仍然是空的...为什么？

使用这段代码从响应中检索 cookie:

/// <summary>
/// Read web cookies
/// </summary>
public static CookieContainer ReadCookies(this HttpResponseMessage response)
{
    var pageUri = response.RequestMessage.RequestUri;

    var cookieContainer = new CookieContainer();
    IEnumerable<string> cookies;
    if (response.Headers.TryGetValues("set-cookie", out cookies))
    {
        foreach (var c in cookies)
        {
            cookieContainer.SetCookies(pageUri, c);
        }
    }

    return cookieContainer;
}
