我在WPF中有一個應用程序，我使用HttpWebRequest在第三方網站發佈登錄，HttpWebRequest.GetResponse工作得很好，並且我得到了我需要的正確的Cookie。HttpClient得不到像HttpWebRequest一樣的CookieContainer
代碼工作正常是：
var cookies = new CookieContainer();
string postData = "[email protected]&senha-passaporte=PASS&urlRetorno=http://sportv.globo.com/site/cartola-fc/&usar-sso=true&botaoacessar=acessar";
byte[] data = new UTF8Encoding().GetBytes(postData);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://loginfree.globo.com/login/438");
request.Timeout = 100000;
request.CookieContainer = cookies;
request.Method = WebRequestMethods.Http.Post;
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)";
request.AllowWriteStreamBuffering = true;
request.ProtocolVersion = HttpVersion.Version11;
request.AllowAutoRedirect = true;
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
Stream newStream = request.GetRequestStream();
newStream.Write(data, 0, data.Length);
newStream.Close();
HttpWebResponse getResponse = (HttpWebResponse)request.GetResponse();
然後，當我試圖端口的Windows 8的商店App這段代碼，使用HttpClient的，我的代碼不返回正確的登錄的Cookie（9塊餅乾代碼以上，僅低於1點的cookie，相同的cookie，我得到的時候使用無效的用戶名或密碼）
var cookies = new CookieContainer();
string postData = "[email protected]&senha-passaporte=PASS&urlRetorno=http://sportv.globo.com/site/cartola-fc/&usar-sso=true&botaoacessar=acessar";
HttpContent content = new StringContent(postData, UTF8Encoding.UTF8);
HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = cookies;
handler.UseCookies = true;
handler.AllowAutoRedirect = true;
var client = new HttpClient(handler);
client.MaxResponseContentBufferSize = 1024 * 1024;
client.Timeout = new TimeSpan(1000000000);
client.DefaultRequestHeaders.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)");
var response = await client.PostAsync("https://loginfree.globo.com/login/438", content);
看來，我認爲該HttpClient.PostAsync沒有發出正確的信息的頁面，但我嘗試幾乎所有的東西，我知道並無法弄清楚它是什麼。
