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();
		
		
		
		
		
	}

}

服务端：

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();
		
	}
