windows Service中的TCP IP监听器

本文关键字：IP 监听器 TCP 中的 Service windows | 更新日期: 2023-09-27 18:03:45

我正在尝试创建一个需要在后台运行并侦听传入流量(正常和常规TCP侦听器)的windows服务

我的代码是: 
private TcpListener server;
public void startServer()
    {
       // EventLog.WriteEntry(source, "connected on: " + ipAddress.ToString() + " port: " + Service1.Port.ToString());
        server = new TcpListener(IPAddress.Parse("127.0.0.1"), Service1.Port);
         server.Start();
        while (true)
        {
          var client = server.AcceptTcpClient();

            new Thread(work).Start(client);
        }
 public void work(object client)
    {
        string msg = null;
        var clientLocal = (TcpClient)client;

            using (NetworkStream ns = clientLocal.GetStream())
            using (StreamReader sr = new StreamReader(ns))
            {
            byte[] msgFullArray = new UTF8Encoding(true).GetBytes(msg);
            fs.Write(msgFullArray, 0, msg.Length);
            }

现在，如果你根本不看工作方法当我启动我的服务时它会冻结每当我试图启动我的:

 var client = server.AcceptTcpClient();

意味着我的服务永远不会使用Thread或我的Work方法。我可以从之前的日志中看到，它进入了while循环，然后就超时了服务

在你的OnStart方法中，你必须实例化一个服务器类。

protected override void OnStart(string[] args)
{
  // Create the Server Object ans Start it.
  server = new TCPServer();
  server.StartServer();
}

负责通过创建一个新的Thread来处理到服务器的连接(因此它是一个非阻塞进程)

public void StartServer()
{
  if (m_server!=null)
  {
    // Create a ArrayList for storing SocketListeners before
    // starting the server.
    m_socketListenersList = new ArrayList();
    // Start the Server and start the thread to listen client 
    // requests.
    m_server.Start();
    m_serverThread = new Thread(new ThreadStart(ServerThreadStart));
    m_serverThread.Start();
    // Create a low priority thread that checks and deletes client
    // SocktConnection objcts that are marked for deletion.
    m_purgingThread = new Thread(new ThreadStart(PurgingThreadStart));
    m_purgingThread.Priority=ThreadPriority.Lowest;
    m_purgingThread.Start();
  }
}

为TCPListener侦听的每个套接字。

private void ServerThreadStart()
{
  // Client Socket variable;
  Socket clientSocket = null;
  TCPSocketListener socketListener = null;
  while(!m_stopServer)
  {
    try
    {
      // Wait for any client requests and if there is any 
      // request from any client accept it (Wait indefinitely).
      clientSocket = m_server.AcceptSocket();
      // Create a SocketListener object for the client.
      socketListener = new TCPSocketListener(clientSocket);
      // Add the socket listener to an array list in a thread 
      // safe fashon.
      //Monitor.Enter(m_socketListenersList);
      lock(m_socketListenersList)
      {
        m_socketListenersList.Add(socketListener);
      }
      //Monitor.Exit(m_socketListenersList);
      // Start a communicating with the client in a different
      // thread.
      socketListener.StartSocketListener();
    }
    catch (SocketException se)
    {
      m_stopServer = true;
    }
  }
}
