python - Python 中的非阻塞 Thrift 服务器

Question

在下面的代码片段中，我试图在 python 中制作一个非阻塞的节俭服务器。

    # set handler to our implementation
    handler = ServiceHandler()

    processor = MyService.Processor(handler)
    transport = TSocket.TServerSocket(port=port)
    tfactory = TTransport.TFramedTransport(transport)  
    pfactory = TBinaryProtocol.TBinaryProtocolFactory()

    # set server
    server = TServer.TThreadedServer(processor, transport, tfactory, pfactory)

    print 'Python Server has started listening on port ' + str(port)
    print '################################################'
    server.serve()

当 python 客户端尝试连接具有上述代码片段的服务器时，我收到以下错误。你能告诉我是什么导致了这个错误吗？可能我遗漏了什么。

    Exception in thread Thread-1:
    Traceback (most recent call last):
    File "/usr/lib64/python2.6/threading.py", line 522, in __bootstrap_inner
    self.run()
    File "/usr/lib64/python2.6/threading.py", line 477, in run
    self.__target(*self.__args, **self.__kwargs)
    File "/usr/local/lib64/python2.6/site-packages/thrift/server/TServer.py", line 114, in handle
    itrans = self.inputTransportFactory.getTransport(client)
    AttributeError: TFramedTransport instance has no attribute 'getTransport'

Answer 1

我找到了一些 working Thrift code并且看起来您的 tfactory 需要是 TBufferedTransportFactory 而不是 TBufferedTransport 实例。

tfactory = TTransport.TBufferedTransportFactory()
