如何使用python套接字编程附加到文件(在重启服务器后的相同字典中)

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

server_address = ('localhost', 8888)
sock.bind(server_address)

sock.listen(1)

print("等待连接...")
client_socket, client_address = sock.accept()

file_name = client_socket.recv(1024).decode()
print("接收文件：", file_name)
file = open(file_name, 'wb')
while True:
    data = client_socket.recv(1024)
    if not data:
        break
    file.write(data)
file.close()

client_socket.close()
sock.close()
