从单独的线程运行的Python ServerSocket

Question

I want to run a Python serversocket class in a separate thread. For that I have modified this code to support python threading:

Original file

import SocketServer

class MyTCPHandler(SocketServer.BaseRequestHandler):
    def handle(self):
        self.data = self.request.recv(1024).strip()
        print self.data

if __name__ == "__main__":
    HOST, PORT = "192.168.65.1", 5001
    server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler) 
    server.serve_forever()

To My file:

import SocketServer

class MyTCPHandler(SocketServer.BaseRequestHandler): 

    def __init__(self):
        self._running = True

    def terminate(self):
        self._running = False

    def setup(self):
         print('{}:{} connected'.format(*self.client_address))

    def handle(self):
        self.data = self.request.recv(1024).strip()
        print self.data

    def finish(self):
         print('{}:{} disconnected'.format(*self.client_address))

#if __name__ == "__main__":
    def run(self):
        HOST, PORT = "192.168.65.1", 5001
        server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler)
        server.serve_forever()

I run it as a separate thread in my main file using

Thread(target=MyTCPHandler().run, args=()).start()

However, when I run the main python file I got this error

----------------------------------------
Exception happened during processing of request from ('192.168.65.1', 37997)
----------------------------------------
Traceback (most recent call last):
  File "/usr/lib/python2.7/SocketServer.py", line 295, in _handle_request_noblock
    self.process_request(request, client_address)
  File "/usr/lib/python2.7/SocketServer.py", line 321, in process_request
    self.finish_request(request, client_address)
  File "/usr/lib/python2.7/SocketServer.py", line 334, in finish_request
    self.RequestHandlerClass(request, client_address, self)
TypeError: __init__() takes exactly 1 argument (4 given)

First, Is my modification to support threading is correct? Please, Can anybody give me a favor?

Answer 1

The problem here is that you are passing incorrect number of parameters to the Parent method here the SocketServer.BaseRequestHandler.

Read about kargs and inheritance and you will understand the problem. In short kargs can take variable number of arguments.

Hope it helps. Change

def __init__(self):
    self._running = True 

to

def __init__(self, *kargs):
    SocketServer.BaseRequestHandler.__init__(self, *kargs)
    self._running = True
