python SocketServer.BaseRequestHandler 知道端口并使用已经打开的端口

Question

这是我玩过的代码，但每次我犯错我都无法重新启动它。它对我说端口/套接字已被使用这是第一个问题第二个在我的 MyTCPHandler 中，我怎么知道使用的端口？这是我的代码:

import SocketServer
import threading

class MyTCPHandler(SocketServer.BaseRequestHandler):
    def handle(self):
        self.data = self.request.recv(1024)
        socket = self.request
        print "%s wrote:" % self.client_address[0]
        print self.data
        print self.__dict__
        socket.sendto(self.data.upper(), self.client_address)

def serve_thread(host, port):
    server = SocketServer.TCPServer((host, port), MyTCPHandler)
    server.serve_forever()

if __name__ == "__main__":
    threading.Thread(target=serve_thread,args=('localhost', 1238)).start()
    threading.Thread(target=serve_thread,args=('localhost', 1237)).start()
    print "toto"

我做了:

def serve_thread(host, port):
    if port == 1858 :
        server = SocketServer.TCPServer((host, port), Serverhttp,bind_and_activate=True)
    elif port == 1958 :
        server = SocketServer.TCPServer((host, port), Serversmtp,bind_and_activate=True)
    server.allow_reuse_address=True
    server.serve_forever()

但它不起作用。问候

实际上比这更容易 -- 您可以将它设置为类变量，而不是重写 init。例如，

class MyServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
    allow_reuse_address = True
