我試圖連接到使用TCP套接字在WCF代碼遠程外部服務器 我的WCF服務是具有使用套接字連接代碼到客戶端外部服務器。 該代碼發送到外部服務器的請求,並接收服務器響應發送或接收數據的請求被禁止,因爲套接字未連接
int byteCount = 0;
Socket m_socClient;
try
{
string query = "My Request String";
m_socClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
System.Net.IPAddress remoteIPAddress = System.Net.IPAddress.Parse("127:0:0:0");
System.Net.IPEndPoint remoteEndPoint = new System.Net.IPEndPoint(remoteIPAddress, 1234);
EVCommon.Log("COnnecting to" + IPSelected + Port);
m_socClient.Connect(remoteEndPoint);
try
{
if (m_socClient.Connected)
{
EVCommon.Log("Connected to" + IPSelected + Port);
var reQuestToSend = string.Format("POST /ZZZZZ HTTP/1.1\r\nContent-Length:{0}\r\n\r\n{1}", query.Length, query);
byte[] bytesToSend = Encoding.ASCII.GetBytes(reQuestToSend);
byteCount = m_socClient.Send(bytesToSend, SocketFlags.None);
byte[] bytesReceived = new byte[1024];
byteCount = m_socClient.Receive(bytesReceived, SocketFlags.None);
Response271 = Encoding.ASCII.GetString(bytesReceived);
m_socClient.Disconnect(false);
m_socClient.Close(5000);
}
}
catch(Exception ex)
{
EVCommon.Log(ex.Message);
}
}
如果我使用相同的客戶端代碼一個窗口應用程序連接到遠程服務器,它是成功的。我能夠連接,發送和接收 只有當我將WCF帶入圖片時纔會出現此錯誤。 if(m_socket.Connected)代碼失敗。所以它無法成功連接。
A request to send or receive data was disallowed because the socket
is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.
謝謝
