运行python-thrift的DEMO

启动服务器和客户端

cd ~/thrift-0.8.0/
thrift -r --gen py tutorial.thrift #生成代码
cd py
./PythonServer.py #启动服务器

cd ~/thrift-0.8.0/py
./PythonClient.py #在另一个shell窗口启动客户端

 

结果启动服务器的时候产生一个错误

shujunli@mysvr1:~/thrift-0.8.0/tutorial/py$ ./PythonServer.py 
Starting the server...
Traceback (most recent call last):
  File "./PythonServer.py", line 95, in <module>
    server.serve()
  File "/usr/lib/python2.7/site-packages/thrift/server/TServer.py", line 74, in serve
    self.serverTransport.listen()
  File "/usr/lib/python2.7/site-packages/thrift/transport/TSocket.py", line 136, in listen
    res0 = self._resolveAddr()
  File "/usr/lib/python2.7/site-packages/thrift/transport/TSocket.py", line 31, in _resolveAddr
    return socket.getaddrinfo(self.host, self.port, socket.AF_UNSPEC, socket.SOCK_STREAM, 0, socket.AI_PASSIVE | socket.AI_ADDRCONFIG)
TypeError: getaddrinfo() argument 1 must be string or None

我们看一下File “PythonServer.py”, line 95，是这句

transport = TSocket.TServerSocket(9090)

我们看TserverSocket源码

def __init__(self, host=None, port=9090, unix_socket=None):

这是因为其初始化函数，第一个参数是host，第二个参数是port，所以想省去host，只填port是不行的，将File “PythonServer.py”, line 95改为：

transport = TSocket.TServerSocket('localhost',9090)

或者

transport = TSocket.TServerSocket(port=9090)

即可解决该问题。
