客户端
向服务器端发数据并且接收服务器的响应
package com.imooc.myFirestSocket; import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import java.io.OutputStream; import java.io.PrintWriter; import java.net.Socket; public class Client { public static void main(String[] args) throws Exception { // 创建一个socket对象 Socket socket = new Socket("localhost", 8888); // 获得输出流 OutputStream os = socket.getOutputStream(); // 写入数据 PrintWriter pw = new PrintWriter(os); pw.write("用户名：admin,密码：123"); pw.flush(); // 关闭输出流 socket.shutdownOutput(); //---->下面是接受服务器发来的响应 // 从socket中读数据 InputStream is = socket.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader bs = new BufferedReader(isr); String str = ""; while ((str = bs.readLine()) != null) { System.out.println("我是客户端，服务器回应说：" + str); } // 关闭输入流 socket.shutdownInput(); // 关闭输入流资源 bs.close(); isr.close(); is.close(); // 关闭输出流资源 pw.close(); os.close(); } }
服务器端
接收客户端的请求并且响应
package com.imooc.myFirestSocket; import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import java.io.OutputStream; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket; import java.util.Date; public class Server { public static void main(String[] args) throws Exception { // 创建一个serverSocket对象,相当于服务器，并且自己设定端口，最好设置1024以后 ServerSocket serverSocket = new ServerSocket(8888); // 调用accept方法监听访问的Socket Socket socket = serverSocket.accept(); // 从socket中读数据 InputStream is = socket.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader bs = new BufferedReader(isr); String str = ""; while ((str = bs.readLine()) != null) { System.out.println("我是服务器，客户端说：" + str); } // 关闭输入流 socket.shutdownInput(); //---->下面是服务器响应客户端 // 获得输出流 OutputStream os = socket.getOutputStream(); // 写入数据 PrintWriter pw = new PrintWriter(os); pw.write("欢迎您："+new Date().toString()); pw.flush(); // 关闭输出流资源 socket.shutdownOutput(); pw.close(); os.close(); // 关闭输入流资源 bs.close(); isr.close(); is.close(); } }
