Question

您好我正在尝试使用单个方法在python（名为PythonServer.py）中编写一个简单的thrift服务器，该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，我在Thrift的python库中遇到以下错误。有没有人遇到过这个问题并建议解决方法？

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

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

你的问题就在于：

transport = TSocket.TServerSocket(port)

当调用TSocket.TServerSocket一个参数时，该值被视为主机标识符，因此错误为getaddrinfo()。

要解决此问题，请将行更改为：

transport = TSocket.TServerSocket(port=port)

Answer 2

运行PythonServer.py时出现此问题...
我改变了这一行

transport = TSocket.TServerSocket(9090)

到

transport = TSocket.TServerSocket('9090')

我的服务器开始运行。

Answer 3

我有类似的问题。我的修复是

List<Long> list = new ArrayList<Long>(data.get("id_list") );

Thrift：TypeError：getaddrinfo（）参数1必须是string或None
