一、服务器与浏览器
// 取得本机的loopback网络地址，即127.0.0.1
IPAddress address = IPAddress.Loopback;
IPEndPoint endPoint = new IPEndPoint(address, 49152);
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.Bind(endPoint);
socket.Listen(10);
Console.WriteLine("开始监听，端口号;{0}.", endPoint.Port);
while (true)
{
Socket client = socket.Accept();
Console.WriteLine(client.RemoteEndPoint);
byte[] buffer = new byte[4096];
int length = client.Receive(buffer, 4096, SocketFlags.None);
System.Text.Encoding utf8 = System.Text.Encoding.UTF8;
string requestString = utf8.GetString(buffer, 0, length);
Console.WriteLine(requestString);
string statusLine = "HTTP/1.1 200 OK\r\n";
byte[] statusLineBytes = utf8.GetBytes(statusLine);
string responseBody = "<html><head><title>From Socket Server</title></head><body><hl>Hello,world.</hl></body></html>";
byte[] responseBodyBytes = utf8.GetBytes(responseBody);
// 回应的头部
string responseHeader = string.Format("Content-Type:text/html;charset=UTF-8\r\nContent-Length:{0}\r\n",
responseBody.Length);
byte[] responseHeaderBytes = utf8.GetBytes(responseHeader);
// 向客户端发送状态消息
client.Send(statusLineBytes);
// 向客户端发送回应头
client.Send(responseHeaderBytes);
client.Send(new byte[] { 13, 10 });
client.Send(responseBodyBytes);
client.Close();
if (Console.KeyAvailable)
{
break;
}
socket.Close();
}
最后在浏览器地址栏中输入：http://localhost:49152
二、服务器客户端
服务端：
class Program{private static byte[] result = new byte[1024];private static int myProt = 8885; //端口static Socket serverSocket;static void Main(string[] args){//服务器IP地址IPAddress ip = IPAddress.Parse("127.0.0.1");serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);serverSocket.Bind(new IPEndPoint(ip, myProt)); //绑定IP地址：端口serverSocket.Listen(10); //设定最多10个排队连接请求Console.WriteLine("启动监听{0}成功", serverSocket.LocalEndPoint.ToString());//通过Clientsoket发送数据Thread myThread = new Thread(ListenClientConnect);myThread.Start();Console.ReadLine();}/// <summary>/// 监听客户端连接/// </summary>private static void ListenClientConnect(){while (true){Socket clientSocket = serverSocket.Accept();clientSocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));Thread receiveThread = new Thread(ReceiveMessage);receiveThread.Start(clientSocket);}}/// <summary>/// 接收消息/// </summary>/// <param name="clientSocket"></param>private static void ReceiveMessage(object clientSocket){Socket myClientSocket = (Socket)clientSocket;while (true){try{//通过clientSocket接收数据int receiveNumber = myClientSocket.Receive(result);Console.WriteLine("接收客户端{0}消息{1}", myClientSocket.RemoteEndPoint.ToString(), Encoding.ASCII.GetString(result, 0, receiveNumber));}catch(Exception ex){Console.WriteLine(ex.Message);myClientSocket.Shutdown(SocketShutdown.Both);myClientSocket.Close();break;}}}}
客户端：
class Program{private static byte[] result = new byte[1024];static void Main(string[] args){//设定服务器IP地址IPAddress ip = IPAddress.Parse("127.0.0.1");Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);try{clientSocket.Connect(new IPEndPoint(ip, 8885)); //配置服务器IP与端口Console.WriteLine("连接服务器成功");}catch{Console.WriteLine("连接服务器失败，请按回车键退出！");return;}//通过clientSocket接收数据int receiveLength = clientSocket.Receive(result);Console.WriteLine("接收服务器消息：{0}",Encoding.ASCII.GetString(result,0,receiveLength));//通过 clientSocket 发送数据for (int i = 0; i < 10; i++){try{Thread.Sleep(1000); //等待1秒钟string sendMessage = "client send Message Hellp" + DateTime.Now;clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));Console.WriteLine("向服务器发送消息：{0}" + sendMessage);}catch{clientSocket.Shutdown(SocketShutdown.Both);clientSocket.Close();break;}}Console.WriteLine("发送完毕，按回车键退出");Console.ReadLine();}}
