CentOS thrift python demo

编辑接口文件 hellowworld.thrift

service HelloWorld {
    string ping(),
    string say(1:string msg)
}

编辑 server.py

#!/usr/bin/env python

import socket
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

class HelloWorldHandler:
  def ping(self):
    return "pong"

  def say(self, msg):
    ret = "Received: " + msg
    print ret
    return ret

handler = HelloWorldHandler()
processor = HelloWorld.Processor(handler)
transport = TSocket.TServerSocket("localhost", 9090)
tfactory = TTransport.TBufferedTransportFactory()
pfactory = TBinaryProtocol.TBinaryProtocolFactory()

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

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

编辑
client.py

#!/usr/bin/env python

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

from helloworld import HelloWorld

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

try:
  transport = TSocket.TSocket('localhost', 9090)
  transport = TTransport.TBufferedTransport(transport)
  protocol = TBinaryProtocol.TBinaryProtocol(transport)
  client = HelloWorld.Client(protocol)
  transport.open()

  print "client - ping"
  print "server - " + client.ping()

  print "client - say"
  msg = client.say("Hello!")
  print "server - " + msg

  transport.close()

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

运行:

thrift --gen py helloworld.thrift
python server.py
python client.py  #这个分一个窗口运行

如果修改里面的一个方法或者增加一个调用方法的话，需要在 helloword.thrift 里面定义函数及参数。

在服务端运行代码 thrift -r --gen py helloworld.thrift

重新生成 gen-py 文件夹，将里面的代码拷贝到客户端的服务器。
