Python：关闭先前的Python程序已经打开的套接字或关闭套接字的肮脏技巧

Question

这是我肮脏的小网络服务器：

class Serverhttp:
def __init__(self):
    self.GET = re.compile("GET.*?HTTP")
    self.POST = re.compile("POST.*?HTTP")
    try :
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        server_address = ('localhost', 36000)
        print >>sys.stderr, 'starting up on %s port %s' % server_address
        sock.bind(server_address)
    except :
        time.sleep(2)
        self.__init__()
    # Listen for incoming connections
    sock.listen(1)
    off = 2
    self.message = ""
    while True:
        # Wait for a connection
        print >>sys.stderr, 'waiting for a connection'
        if off == 2 or off == 1:
            connection, client_address = sock.accept()
        try:
            print >>sys.stderr, 'connection from', client_address

            # Receive the data in small chunks and retransmit it
            while True:
                data = connection.recv(1024)
                print >>sys.stderr, 'received "%s"' % data
                if data:
                    self.message = self.traitement(data)
                    connection.sendall(self.message)
                    connection.close()
                    connection, client_address = sock.accept()

                else:
                    print >>sys.stderr, 'no more data from', client_address
                    break

        finally:
            # Clean up the connection
            connection.close()
            sock.close()
            del(sock)

它或多或少可以工作，但如果我退出服务器，端口仍然打开，我无法在同一端口上重新连接。所以我正在寻找一种方法来终止先前的套接字或以一种好的方式退出。 问候和感

Answer 1

sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

应该可以解决问题。
