Question

我在WPF中有一个应用程序，我使用HttpWebRequest在第三方网站发布登录，HttpWebRequest.GetResponse运行良好，我得到了我需要的正确的cookie。

正常运行的代码是：

var cookies = new CookieContainer();
string postData = "login-passaporte=email@yahoo.com.br&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();

然后，当我尝试使用HttpClient将此代码移植到Windows 8商店应用程序时，我的代码不会返回正确记录的cookie（上面的代码上有9个cookie，下面只有1个cookie，使用时会得到相同的cookie）用户名或密码无效）

var cookies = new CookieContainer();

string postData = "login-passaporte=email@yahoo.com.br&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);

在我看来，HttpClient.PostAsync没有向页面发送正确的信息，但我几乎尝试了所有我知道的东西，但却无法弄清楚它是什么。

PS。：此用户名和密码只是测试的工作帐户。

看起来我忘了将Content-Type传递给我的HttpContent。

要修复我的代码，我只需要在StringContent构造函数中添加另一个参数。

HttpContent content = new StringContent(postData, UTF8Encoding.UTF8, "application/x-www-form-urlencoded");

HttpClient与HttpWebRequest没有相同的CookieContainer
