网络编程【九】Tcp 图片的上传
图片的上传服务器操作练习。
客户端把d:\pic\welcome.jpg 这张图片图片上传到服务器。服务器收到图片后把存片存在："d:\data\server.jpg"，并给客户端返回：“上传成功”。注意，这里用的是字节流。
客户端：
import java.net.*;import java.io.*;public class TcpClient {public static void main(String[] args)throws Exception {Socket s = new Socket("192.168.0.124",10006);FileInputStream fis = new FileInputStream("d:\\pic\\welcome.jpg");OutputStream out = s.getOutputStream(); byte[] buf = new byte[1024];int len = 0;while((len=fis.read(buf))!=-1){out.write(buf,0,len);}s.shutdownOutput();InputStream in = s.getInputStream();byte[] bufIn = new byte[1024];int number = in.read(bufIn);System.out.println(new String(bufIn,0,number));fis.close();s.close();}}import java.net.*;import java.io.*;class TcpServer {public static void main(String[] args)throws Exception {ServerSocket ss = new ServerSocket(10006);Socket s = ss.accept();String ip = s.getInetAddress().getHostAddress();System.out.println(ip+"---> connect");FileOutputStream fos = new FileOutputStream("d:\\data\\server.jpg");InputStream in = s.getInputStream();byte[] buf = new byte[1024];int len = 0;while((len=in.read(buf))!=-1){fos.write(buf,0,len);}OutputStream out = s.getOutputStream();out.write("上传成功".getBytes());fos.close();s.close();ss.close();out.close();s.close();ss.close();}}
