Python Socket Server - Kick Function-CodePudding

I'm trying to kick client from the server, and after that I get the follwing exception:

Exception in thread Thread-2 (__handle_client):
Traceback (most recent call last):
  File "/Users/macbook/Desktop/Python Projects/Cars/Server/server.py", line 36, in __handle_client
    message = client.recv(1024).decode(FORMAT) 
OSError: [Errno 9] Bad file descriptor

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/threading.py", line 1009, in _bootstrap_inner
    self.run()
  File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/threading.py", line 946, in run
    self._target(*self._args, **self._kwargs)
  File "/Users/macbook/Desktop/Python Projects/Cars/Server/server.py", line 41, in __handle_client
    client.send('You left the chat room'.encode(FORMAT)) 
OSError: [Errno 9] Bad file descriptor.

But when I use the exit function it is going well. Both using the __close_connection function.

This is my Code:

def __handle_client(self,client):
    while True:
        try:
            message = client.recv(1024).decode(FORMAT) 
            if self.__handle_messsage(message,client) == True:
                break
        except:
            client.send('You left the chat room'.encode(FORMAT))
            self.__broadcast(f'{self.__clientnick[client]} has left the chat room!',)
            del self.__clientnick[client]
            client.close()
            break

    def __handle_messsage(self,message,client): 
    if  message == '/exit':
        exit_message = 'You have discinnected successfully.'
        self.__close_connction(exit_message,client)
        return True

    if message.startswith('/kick'):
        if self.__clientnick.get(client) == 'admin':
            for check_client in self.__clientnick: 
                if self.__clientnick.get(check_client) == message[6:len(message)]:
                    kick_message = 'You have been kicket from the chat room.'
                    self.__close_connction(kick_message,check_client)
                    return True
        else:
            client.send('You are not admin!'.encode(FORMAT))

    def __close_connection(self,message,client):
       client.send(message.encode(FORMAT))
       self.__broadcast(f'{self.__clientnick[client]} has left the chat room!',client)
       del self.__clientnick[client]
       client.close()

CodePudding user response：

It seems that you already closed the connection when you did kick and that is why you get the exception. the second exception is when you try to send a message to the closed connection.
