环境：Python 3.6.2 Thrift 0.9.3

客户端代码：

from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from message.api import MessageService

from io import *
__HOST = 'localhost'
__PORT = 8800

b = StringIO()

tsocket = TSocket.TSocket(__HOST, __PORT)
transport = TTransport.TBufferedTransport(tsocket)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = MessageService.Client(protocol)
client.send_sendEmailMessage()

transport.open()

服务端代码：

from message.api import MessageService
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from thrift.server import TServer


class MessageServiceHandler:
   def sendMobileMessage(self):
       print("sendMobileMessage")
       return True

   def sendEmailMessage(self):
       print("sendEmailMessage")
       return True


if __name__ == "__main__":
   handler = MessageServiceHandler()
   processor = MessageService.Processor(handler)
   transport = TSocket.TServerSocket("localhost", 8800)
   tfactory = TTransport.TBufferedTransportFactory()
   pfactory = TBinaryProtocol.TBinaryProtocolFactory()

   server = TServer.TSimpleServer(processor, transport, tfactory, pfactory)
   print("python thrift server start")
   server.serve()
   print("python thrift server exit")
