php服务端的代码要在类似apache的服务器中运行,代码如下:- <?php
- //确保在连接客户端时不会超时
- set_time_limit(0);
- //设置IP和端口号
- $address='127.0.0.1';
- $port=3333; //调试的时候,可以多换端口来测试程序!
- //创建一个SOCKET
- if(($sock=socket_create(AF_INET,SOCK_STREAM,SOL_TCP))<0)
- {
- echo "socket_create() 失败的原因是:".socket_strerror($sock)."<br>";
- }
- //绑定到socket端口
- if(($ret=socket_bind($sock,$address,$port))<0)
- {
- echo "socket_bind() 失败的原因是:".socket_strerror($ret)."<br>";
- }
- //开始监听
- if(($ret=socket_listen($sock,4))<0)
- {
- echo "socket_listen() 失败的原因是:".socket_strerror($ret)."<br>";
- }
- do {
- if (($msgsock = socket_accept($sock)) < 0)
- {
- echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "/n";
- echo "/nThe Server is Stop……/n";
- break;
- }
- //发到客户端
- $msg ="<font color=red>Welcome To Server!</font><br>";
- socket_write($msgsock, $msg, strlen($msg));
- socket_close($msgsock);
- echo "/nThe Server is running……/n";
- printf("/nThe Server is running……/n");
- } while (true);
- socket_close($sock);
- ?>
android客户端在同一台机器上的模拟器中运行,代码如下:
- import java.io.IOException;
- import java.io.InputStream;
- import java.io.OutputStream;
- import java.net.Socket;
- import java.net.UnknownHostException;
- import android.app.Activity;
- import android.content.Intent;
- import android.os.Bundle;
- public class SocketTest extends Activity {
- /** Called when the activity is first created. */
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- try {
- System.out.println("准备连接");
- Socket socket = new Socket("10.0.2.2", 3333);
- System.out.println("连接上了");
- Intent intent = new Intent();
- intent.setClass(SocketTest.this, ConnectActivity.class);
- SocketTest.this.startActivity(intent);
- InputStream inputStream = socket.getInputStream();
- byte buffer[] = new byte[1024*4];
- int temp = 0;
- String res = null;
- //从inputstream中读取客户端所发送的数据
- System.out.println("接收到服务器的信息是:");
- while ((temp = inputStream.read(buffer)) != -1){
- System.out.println(new String(buffer, 0, temp));
- res += new String(buffer, 0, temp);
- }
- System.out.println("已经结束接收信息……");
- socket.close();
- inputStream.close();
- } catch (UnknownHostException e) {
- e.printStackTrace();
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- }
注:服务端的程序要先运行起来,然后运行客户端。这只是一个简单的socket通信。
