C# http服务器代码

在C#中创建一个基本的HTTP服务器，可以使用内置的System.Net.HttpListener类。下面是一个简单的示例，展示了如何创建一个监听特定端口的HTTP服务器：

using System;
using System.Net;
using System.IO;

class SimpleHttpServer
{
    private HttpListener listener;

    public void Start(int port)
    {
        listener = new HttpListener();
        listener.Prefixes.Add("http://localhost:" + port + "/");

        listener.Start();

        Console.WriteLine($"Server started on port {port}.\nPress any key to stop...");
        Console.ReadKey();

        // 接收并处理请求
        while (true)
        {
            try
            {
                var context = listener.GetContext();
                HandleRequest(context.Request, context.Response);
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error: {ex.Message}");
            }
        }

        listener.Stop();
    }

    private void HandleRequest(HttpListenerRequest request, HttpListenerResponse response)
    {
        string requestBody = "";
        using (var reader = new StreamReader(request.InputStream))
        {
            requestBody = reader.ReadToEnd();
        }

        string responseBody = "Hello from C# HTTP server!";
        
        // 设置响应头和内容
        response.ContentType = "text/plain";
        response.StatusCode = 200; // OK
        using (StreamWriter writer = new StreamWriter(response.OutputStream))
        {
            writer.Write(responseBody);
        }

        // 关闭输入流和输出流
        request.InputStream.Close();
        response.OutputStream.Close();
    }
}

public static class Program
{
    public static void Main(string[] args)
    {
        int port = 8080;
        if (args.Length > 0)
        {
            port = Convert.ToInt32(args[0]);
        }

        SimpleHttpServer server = new SimpleHttpServer();
        server.Start(port);
    }
}

这个代码会监听指定的端口（默认8080），接收到所有GET请求，返回固定的字符串"Hello from C# HTTP server!"。你可以根据需要扩展HandleRequest方法来处理不同的请求。
