c# - C# SslStream 不适合登录到 facebook 吗？

Question

已解决:SslStream 不会一次读取整个数据包...

---

我正在尝试使用一些准备好的数据包登录到 m.facebook.com。我用 SslStream 发送它。回复好像没问题但它不包含所需的名为 xs 的 cookie。我认为我准备的数据包有问题。但是我尝试用 Fiddler 和 SocketTest3 发送完全相同的数据包，我收到了 cookie。可能是什么问题。

我使用的代码， Conceal 了登录名和密码。

   static void Main(string[] args)
    {
        SslTcpClient.TryLogin("m.facebook.com", "m.facebook.com");
        Console.ReadKey(true);
    }

   public class SslTcpClient
    {
        private static Hashtable certificateErrors = new Hashtable();

        public static bool ValidateServerCertificate(
              object sender,
              X509Certificate certificate,
              X509Chain chain,
              SslPolicyErrors sslPolicyErrors)
        {
            if (sslPolicyErrors == SslPolicyErrors.None)
                return true;

            Console.WriteLine("Certificate error: {0}", sslPolicyErrors);

            return false;
        }
        public static void TryLogin(string machineName, string serverName)
        {
            TcpClient client = new TcpClient(machineName, 443);
            Console.WriteLine("Client connected.");
            SslStream sslStream = new SslStream(
                client.GetStream(),
                false,
                new RemoteCertificateValidationCallback(ValidateServerCertificate),
                null
                );
            try
            {
                sslStream.AuthenticateAsClient(serverName);
            }
            catch (AuthenticationException e)
            {
                Console.WriteLine("Exception: {0}", e.Message);
                if (e.InnerException != null)
                {
                    Console.WriteLine("Inner exception: {0}", e.InnerException.Message);
                }
                Console.WriteLine("Authentication failed - closing the connection.");
                client.Close();
                return;
            }
            var message = "POST https://m.facebook.com/login.php?refsrc=https%3A%2F%2Fm.facebook.com%2F&refid=8 HTTP/1.1\r\n" +

            byte[] messsage = Encoding.UTF8.GetBytes(message);
            sslStream.Write(messsage);
            sslStream.Flush();
            var buffer = new byte[10000];
            int r = sslStream.Read(buffer,0,buffer.Length);
            string serverMessage = Encoding.UTF8.GetString(buffer, 0, r);
            Console.WriteLine("Server says: {0}", serverMessage);
            client.Close();
            Console.WriteLine("Client closed.");
        }

    }

已解决:SslStream 不会一次读取整个 header 。需要调用 Double Read 方法。Facebook 可能会单独发送 header 的各个部分。
