C#写的客户端连接 php的服务器端的小例子

php的server 端

1. <?php
2. // server.php
3. set_time_limit( 0 );
4. ob_implicit_flush();
5. $socket = socket_create( AF_INET, SOCK_STREAM, SOL_TCP );
6. socket_bind( $socket, ‘127.0.0.1‘, 8880 );
7. socket_listen($socket);
8. $acpt=socket_accept($socket);
9. echo "> Acpt!\n";
10. while ( $acpt ) {
11. echo "> ";
12. $words= trim(fgets(STDIN));
13. if(strlen($words) === 0) $words = "\n";
14. socket_write($acpt,$words);
15. $hear=socket_read($acpt,1024);
16. echo "client>" . $hear . "\n" ;
17. if("bye"==$hear){
18. socket_shutdown($acpt);
19. break;
20. }
21. usleep( 1000 );
22. }
23. socket_close($socket);
24. echo "> bye bye\n";
25. ?>

以交互式方法运行：

1. php -a server.php

C#写的客户端

1. public class Client
2. {
3. private static byte[] result = new byte[1024];
4. public string serverIp = "127.0.0.1";
5. public int severPort = 8880;
6. public Client(string serverIp, int serverPort)
7. {
8. this.serverIp = serverIp;
9. this.severPort = serverPort;
10. }
11. public void start()
12. {
13. //设定服务器IP地址
14. IPAddress ip = IPAddress.Parse(serverIp);
15. Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
16. try {
17. clientSocket.Connect(new IPEndPoint(ip, severPort));
18. Console.WriteLine("连接服务器成功");
19. } catch {
20. Console.WriteLine("连接服务器失败");
21. return;
22. }
23. int receiveLength;
24. while (clientSocket.Connected) {
25. receiveLength = clientSocket.Receive(result);
26. string sv_word = Encoding.ASCII.GetString(result, 0, receiveLength);
27. Console.WriteLine("Sever> {0}", sv_word);
28. if (sv_word.Trim() == "bye") break;
29. Console.Write("> ");
30. string words = Console.ReadLine();
31. if (string.IsNullOrEmpty(words)) words = "\n";
32. clientSocket.Send(Encoding.ASCII.GetBytes(words));
33. if (words.Trim() == "bye") break;
34. }
35. if(clientSocket.Connected) clientSocket.Close();
36. Console.WriteLine("> bye bye");
37. }
38. }

加入引入

1. using System.Net;
2. using System.Net.Sockets;
3. using System.Threading;

在某处调用

1. new Client("127.0.0.1", 8880).start();
