  自己写一个简单的Web服务器,对加深理解Http协议有很好的帮助,下面就看一下一个基于TcpListener的Web服务器:

class Program
{
static void Main(string[] args)
{
IPAddress address = IPAddress.Loopback;
IPEndPoint endPoint = new IPEndPoint(address, ); TcpListener newserver = new TcpListener(endPoint);
newserver.Start();
Console.WriteLine("开始监听......"); while (true)
{
TcpClient newclient = newserver.AcceptTcpClient();
Console.WriteLine("已经建立连接"); NetworkStream ns = newclient.GetStream(); System.Text.Encoding utf8 = System.Text.Encoding.UTF8; byte[] request=new byte[];
int lehgth = ns.Read(request, , );
string requestString = utf8.GetString(request); Console.WriteLine(requestString); string statusLine = "HTTP/1.1 200 OK\r\n";
byte[] statusLineBytes = utf8.GetBytes(statusLine); string responseBody = "<html><head><body><h1>hello world</h1></body></head></html>"; byte[] responseBodyBytes = utf8.GetBytes(responseBody); //回应头部分
string responseHeader = string.Format("Content-Type:text/html;charset=UTF-8\r\nContent-Length:{0}\r\n",responseBody.Length); byte[] responseHeaderBytes = utf8.GetBytes(responseHeader); ns.Write(statusLineBytes, , statusLineBytes.Length);
ns.Write(responseHeaderBytes, , responseHeaderBytes.Length);
ns.Write(new byte[] { , }, , );
ns.Write(responseBodyBytes, , responseBodyBytes.Length);
newclient.Close(); if (Console.KeyAvailable)
break;
}
newserver.Stop();
}

运行程序,然后打开浏览器,在浏览器窗口中输入服务器的地址:http://localhost:49152,这时就回看到服务器返回的数据。
