在编写python的thrift代码时,需要先安装thrift module

$ cd thrift-root/lib/py/
$ sudo python setup.py install

下面是一个python的例子 helloworld.thrift

 

const string HELLO_IN_KOREAN = "an-nyoung-ha-se-yo"

const string HELLO_IN_FRENCH = "bonjour!"

const string HELLO_IN_JAPANESE = "konichiwa!"

service HelloWorld {
 void ping(),
 string sayHello(),
 string sayMsg(1:string msg)
}


生产代码

$ thrift -r --gen py helloworld.thrift

编写服务器PythonServer.py

#!/usr/bin/env python

import sys
sys.path.append('./gen-py')
 
from helloworld import HelloWorld
from helloworld.ttypes import *

from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from thrift.server import TServer
 
import socket

class HelloWorldHandler:
  def __init__(self):
    self.log = {}

  def ping(self):
    print "ping()"

  def sayHello(self):
    print "sayHello()"
    return "say hello from " + socket.gethostbyname(socket.gethostname())

  def sayMsg(self, msg):
    print "sayMsg(" + msg + ")"
    return "say " + msg + " from " + socket.gethostbyname(socket.gethostname())

handler = HelloWorldHandler()
processor = HelloWorld.Processor(handler)
transport = TSocket.TServerSocket('127.0.0.1',30303)
tfactory = TTransport.TBufferedTransportFactory()
pfactory = TBinaryProtocol.TBinaryProtocolFactory()

server = TServer.TSimpleServer(processor, transport, tfactory, pfactory)

print "Starting python server..."
server.serve()
print "done!"

编写客户端PythonClient.py

#!/usr/bin/env python

import sys
sys.path.append('./gen-py')

from helloworld import HelloWorld
from helloworld.ttypes import *
from helloworld.constants import *

from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol

try:
  # Make socket
  transport = TSocket.TSocket('127.0.0.1', 30303)

  # Buffering is critical. Raw sockets are very slow
  transport = TTransport.TBufferedTransport(transport)

  # Wrap in a protocol
  protocol = TBinaryProtocol.TBinaryProtocol(transport)

  # Create a client to use the protocol encoder
  client = HelloWorld.Client(protocol)

  # Connect!
  transport.open()

  client.ping()
  print "ping()"

  msg = client.sayHello()
  print msg
  msg = client.sayMsg(HELLO_IN_KOREAN)
  print msg

  transport.close()

except Thrift.TException, tx:
  print "%s" % (tx.message)

运行程序

$ python PythonServer.py
$ python PythonClient.py
