文章结束给大家来个程序员笑话：[M]
TCP：Transmission Control Protocol 传输控制议协TCP是一种面向连接（连接导向）的、牢靠的、基于字节流的运输层（Transport layer）信通议协，由IETF的RFC 793明说（specified）。在简化的计算机网络OSI型模中，它成完第四层传输层所指定的功能，UDP是一同层内另一个主要的传输议协。
本文模拟客户端通过TCP向服务端发起登录请求来实现这一功能。
一、服务端
package com.figo.helloworld.action;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
/**
* 服务端Tcp登录接口，收接客户端登录请求
*
* @author zhuzhifei 版权所有
*
*/
public class TcpAction implements Runnable {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("start");
Thread desktopServerThread = new Thread(new TcpAction());
desktopServerThread.start();
}
public void run() {
try {
// 创立ServerSocket
ServerSocket serverSocket = new ServerSocket(8088);// 设置8088端口
while (true) {
// 接受客户端请求
Socket client = serverSocket.accept();
System.out.println("accept");
try {
// 收接客户端息消
BufferedReader in = new BufferedReader(
new InputStreamReader(client.getInputStream()));
String str = in.readLine();
System.out.println("read:" + str);
// 向服务器发送息消
PrintWriter out = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(client.getOutputStream())),
true);
if ("123|abc".equals(str)) {
out.println("server message:" + "login success");
} else {
out.println("server message:"
+ "userName or password is error");
}
// 关闭流
out.close();
in.close();
} catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
} finally {
// 关闭
client.close();
System.out.println("close");
}
}
}
catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
二、客户端
package com.figo.helloworld;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketTimeoutException;
import org.apache.http.conn.ConnectTimeoutException;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
/**
* 这个Activity模拟用使Socket信通来调用服务端的登录接口
*
* @author zhuzhifei 版权所有
*
*/
public class TcpActivity extends Activity {
Button buttonLogin;
EditText etUserName;
EditText etPwd;
TextView tvResult;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tcptest);
buttonLogin = (Button) findViewById(R.id.buttonLogin);
etUserName = (EditText) findViewById(R.id.etUserName);
etPwd = (EditText) findViewById(R.id.etPwd);
tvResult = (TextView) findViewById(R.id.tvResult);
buttonLogin.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Socket socket = null;
String message = etUserName.getText().toString() + "|"
+ etPwd.getText().toString();
try {
// 创立Socket
socket = new Socket();
socket.connect(new InetSocketAddress("10.241.72.35", 8088),
30000);// 30秒钟连接时超
socket.setSoTimeout(30000);// 30秒钟信通时超
socket.setTcpNoDelay(true);
// 向服务器发送息消
PrintWriter out = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(socket.getOutputStream())),
true);
out.println(message);
// 收接来自服务器的息消
BufferedReader br = new BufferedReader(
new InputStreamReader(socket.getInputStream()));
String msg = br.readLine();
if (msg != null) {
tvResult.setText(msg);
} else {
tvResult.setText("据数错误!");
}
// 关闭流
out.close();
br.close();
// 关闭Socket
socket.close();
} catch (ConnectTimeoutException e) {
Log.e("tcp", e.toString());
} catch (SocketTimeoutException e) {
Log.e("tcp", e.toString());
} catch (Exception e) {
Log.e("tcp", e.toString());
}
}
});
}
}
