客户端关闭文件时，套接字连接将断开连接

Question

我试图通过在python 3.4中使用套接字服务器来接收img，并且客户端正在使用android.I已经完成了写img.But问题是客户端关闭了img文件，然后连接也会断开连接。我该如何解决这个问题？

我的服务器代码如下：

import socket
import struct
import sys
address = ("10.0.0.22", 5000)
try:
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except (socket.error, msg):
    print ('Failed to create socket.Error code:' + str(msg[0]) + ', Error    message: ' + msg[1])
sys.exit()
print ('Socket Created')
s.bind(address)
s.listen(5)

while True:
    (client, addr) = s.accept()
    print ('got connected from', client,addr)
    buf = b''
    while len(buf)<4:
        buf += client.recv(4-len(buf))
    size = struct.unpack('!i', buf)
    print ("receiving %s bytes" % size)

    with open('tst.jpg', 'wb') as img:
        while True:
            data = client.recv(1024)
            print (data)
            if not data:
                break
            img.write(data)
    img.close()
print ('received, yay!')
#write json file
...
with open('a.json','r+') as data_file:
    data = json.dumps(json.load(data_file)).encode('utf-8')
    client.sendall(data)
print('send json, yay!')
client.close()

我的客户端代码如下

FileOutputStream fop;
Socket socket;
try {
    fop=new FileOutputStream("/sdcard/dd.jpg");
    bmp.compress(Bitmap.CompressFormat.JPEG, 100, fop);
    fop.close();
    Toast.makeText(MainActivity.this, "saved",Toast.LENGTH_LONG).show();

    InetAddress serverAdd = InetAddress.getByName("10.0.0.22");
    SocketAddress sc_add = new InetSocketAddress(serverAdd,5000);
    socket = new Socket();
    socket.connect(sc_add,2000);

    DataOutputStream out = new DataOutputStream(socket.getOutputStream());
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    byte[] bytes = baos.toByteArray();
    out.write(bytes);
    out.close();
    out.flush();

    InputStream inputStream = socket.getInputStream();
    byte buffer[] = new byte[1024 * 4];
    int temp = 0;
    while ((temp = inputStream.read(buffer) != -1)){
    System.out.println(new String(buffer,0,temp));
    }
    socket.close();
}
