Python HTTP服务器不发送响应

Question

这里有两个脚本。一个是主脚本，另一个是Server Handler。通过主脚本Im调用Handler。 服务器将启动但无法发送响应。 请帮助我。

主要文字：

def start_server(message_queue):

    print time.asctime(), "Server Start - %s:%s" % (HOST_NAME, PORT)
    httpd = SocketServer.ThreadingTCPServer((HOST_NAME, PORT), ServerHandler(message_queue))
    httpd.serve_forever()
    print time.asctime(), "Server Stops - %s:%s" % (HOST_NAME, PORT)


if __name__ == '__main__':
    logging.basicConfig(filename=LOG_PATH, level=LOG_LEVEL, format='%(asctime)s-%(levelname)s-%(message)s')

    queue = Queue()
    process_new = Process(target=start_server, args=(queue,))
    process_new.start()
    queue.put("INSUFFICIENT_CREDIT")

服务器处理程序：

class ServerHandler(SocketServer.ThreadingMixIn,SimpleHTTPServer.SimpleHTTPRequestHandler):

    def __init__(self, message_queue):
         self.queue = message_queue


    def do_POST(self,message_queue):
        message = message_queue.get()
        if message is None:
            print "Test result"
        else:
            "SUCCESS"

        self.send_response(200)
        self.end_headers()
