python - 节俭 : TypeError: getaddrinfo() argument 1 must be string or None

Question

您好，我正在尝试用 python 编写一个简单的 thrift 服务器(名为 PythonServer.py)，使用一个方法返回一个字符串用于学习目的。服务器代码如下。当我运行服务器时，Thrift 的 python 库中出现以下错误。有没有人遇到过这个问题并提出了解决方法？

执行输出:

    Starting server
    Traceback (most recent call last):
    File "/home/dae/workspace/BasicTestEnvironmentV1.0/src/PythonServer.py", line     38,     in <module>
    server.serve()
    File "usr/lib/python2.6/site-packages/thrift/server/TServer.py", line 101, in serve
    File "usr/lib/python2.6/site-packages/thrift/transport/TSocket.py", line 136, in      listen
    File "usr/lib/python2.6/site-packages/thrift/transport/TSocket.py", line 31, in      _resolveAddr
    TypeError: getaddrinfo() argument 1 must be string or None

Python服务器.java

     port = 9090

     import MyService as myserv
     #from ttypes import *

     # Thrift files
     from thrift.transport import TSocket
     from thrift.transport import TTransport
     from thrift.protocol import TBinaryProtocol
     from thrift.server import TServer

     # Server implementation
     class MyHandler:
         # return server message
         def sendMessage(self, text):
             print text
             return 'In the garage!!!'


     # set handler to our implementation
     handler = MyHandler()

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

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

     print 'Starting server'
     server.serve() ##### LINE 38 GOES HERE ##########

你的问题是:

transport = TSocket.TServerSocket(port)

当调用单个参数的 TSocket.TServerSocket 时，该值被视为主机标识符，因此 getaddrinfo() 出错。

要解决这个问题，请将行更改为:

transport = TSocket.TServerSocket(port=port)
