ASP.NET Socket 数据传输主要涉及到创建一个套接字服务器,监听客户端连接,接收和发送数据。以下是一个简单的示例,展示了如何使用 ASP.NET Core 创建一个 Socket 服务器来传输数据:

  1. 首先,创建一个新的 ASP.NET Core 控制台应用程序:
dotnet new console -o AspNetCoreSocketServer
cd AspNetCoreSocketServer
  1. 在项目中添加以下命名空间:
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
  1. 创建一个名为 SocketServer 的新类,该类将包含服务器的主要逻辑:
public class SocketServer
{
    private const int Port = 5000;

    public static async Task Main(string[] args)
    {
        var server = new SocketServer();
        await server.Start();
    }

    public async Task Start()
    {
        var listener = new TcpListener(IPAddress.Any, Port);
        listener.Start();
        Console.WriteLine($"Server started on port {Port}");

        while (true)
        {
            var client = await listener.AcceptTcpClientAsync();
            Console.WriteLine($"Client connected: {client.Client.RemoteEndPoint}");

            var task = HandleClientAsync(client);
            Task.Run(task);
        }
    }

    private async Task HandleClientAsync(TcpClient client)
    {
        var stream = client.GetStream();
        byte[] buffer = new byte[1024];

        while (true)
        {
            int bytesRead = await stream.ReadAsync(buffer, 0, buffer.Length);
            if (bytesRead == 0) break;

            string receivedData = Encoding.UTF8.GetString(buffer, 0, bytesRead);
            Console.WriteLine($"Received data: {receivedData}");

            string response = "Message received";
            byte[] responseBytes = Encoding.UTF8.GetBytes(response);
            await stream.WriteAsync(responseBytes, 0, responseBytes.Length);
        }

        client.Close();
        Console.WriteLine($"Client disconnected: {client.Client.RemoteEndPoint}");
    }
}
  1. Program.cs 中调用 SocketServer 类的 Main 方法来启动服务器:
public static async Task Main(string[] args)
{
    var builder = WebApplication.CreateBuilder(args);
    // ... 其他配置

    var app = builder.Build();

    if (app.Environment.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseRouting();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers();
    });

    await SocketServer.Main(args);
}

现在,当客户端连接到服务器时,服务器将接收客户端发送的数据,并在控制台中显示接收到的消息。同时,服务器将发送一条确认消息给客户端。

要测试此服务器,可以创建一个简单的 ASP.NET Core 控制台应用程序,使用 TcpClient 类连接到服务器并发送/接收数据。
