Socket基础使用

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();

	}
