Thrift: 类型错误：getaddrinfo() 参数1必须是字符串或None

Question

你好，我正在尝试用Python写一个简单的Thrift服务器（叫做PythonServer.py），里面只有一个方法可以返回一个字符串，目的是为了学习。下面是服务器的代码。当我运行这个服务器时，Thrift的Python库出现了一些错误。有没有人遇到过这个问题，能给我一些解决办法吗？

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

PythonServer.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 ########## 

Answer 1

我也遇到过类似的问题。我的解决办法是：

TSocket.TServerSocket('your server ip',port) 

Answer 2

transport = TSocket.TServerSocket('9090')

我在运行 PythonServer.py 的时候遇到了这个问题...
我把这一行代码改成了

transport = TSocket.TServerSocket(9090)

然后我的服务器就开始正常运行了。

Answer 3

你的问题出在这一行：

transport = TSocket.TServerSocket(port)

当你调用 TSocket.TServerSocket 并且只传入一个参数时，这个值会被当作主机标识符来处理，因此会出现 getaddrinfo() 的错误。

要解决这个问题，把这一行改成：

transport = TSocket.TServerSocket(port=port)
