用于长时间运行连接的可扩展 TCP/IP 服务器
在设计建立长时间运行的 TCP/IP 连接的可扩展 Windows 服务应用程序时,几个关键的考虑因素开始发挥作用:
可扩展性注意事项:
示例实现:
using System; using System.Net; using System.Net.Sockets; using System.Threading; public class ScalableServer { // Server configuration constants private const int Port = 8080; private const int Backlog = 100; // List of active client connections private List<Socket> _sockets; private ServerSocket _serverSocket; // Initialize the server public bool Start() { // Create a server socket and start listening for connections try { _serverSocket = new ServerSocket(IPAddress.Any, Port, Backlog); _serverSocket.Listen(); } catch (SocketException e) { Console.WriteLine($"Error starting server: {e.Message}"); return false; } // Start accepting client connections asynchronously _serverSocket.BeginAccept(HandleClient); return true; } // Handle incoming client connections private void HandleClient(IAsyncResult result) { try { // Get the client socket Socket clientSocket = _serverSocket.EndAccept(result); // Add the client socket to the active list _sockets.Add(clientSocket); // Begin receiving data from the client asynchronously clientSocket.BeginReceive(...); // ... Implement data handling and message processing here } catch (SocketException e) { Console.WriteLine($"Error handling client connection: {e.Message}"); } } }
此示例演示了处理长连接的基本服务器架构运行 TCP/IP 连接并提供异步 I/O 以提高可扩展性。
