socket传照片java服务器python客户端

这是java写的web端的server:

import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;
 
public class SS {
 
	public static void main(String[] args) throws Exception{
		ServerSocket ss = new ServerSocket(5612);
		System.out.println("服务端已启动，正在监听端口...");
		byte[] buf = new byte[1024];
		byte[] img = new byte[1024];
		
		while(true) 
		{
			Socket s = ss.accept();
			System.out.println("检测到客户端，准备数据接收...");
			InputStream in = s.getInputStream();
			
			in.read(buf);  
			
	        String str = new String(buf).trim();
	        System.out.println(str);

	        File file=new File("E:\\2.jpg");
	        FileOutputStream fout=new FileOutputStream(file);
	        int len=0;
	        while((len=in.read(img))!=-1)
	        {
	            fout.write(img,0,len);
	        }
	      
	        fout.flush();
	        fout.close();
			in.close();
			s.close();

		}
		
	}

	
}

这是python写的客户端:

import base64
import socket
import os
import sys
import struct




s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# # s.connect(('47.106.34.7', 8899))
s.connect(('127.0.0.1', 5612))
content=str('person:'+str(2)+',head:'+str(2)+',helmet:'+str(0)).encode("utf-8")
print(type(content))
# b2 = bytes(content)
s.send(content)



filepath = r'F:\Insects\sdfe\sdfe11.jpg'
with open(filepath, 'rb') as fp:
    data = fp.read()
    # print(type(img))
msg=content+data
s.send(data)
print((msg))


# s.send(content)
# print(content)
# s.close()
