Python Thrift sample <转> __python

Turn from: http://tkang.blogspot.com/2010/07/thrift-server-client-in-python.html

When writing Python thrift code, you need to first install thrift module

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

Here's a python example 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)
}

Production Code

$ thrift-r--gen py Helloworld.thrift

Writing server pythonserver.py

#!/usr/bin/env python import sys sys.path.append ('./gen-py ') from HelloWorld import HelloWorld from Helloworld.ttypes I Mport * from Thrift.transport import tsocket to Thrift.transport import ttransport from Thrift.protocol import Tbinaryp Rotocol 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" + Socke T.gethostbyname (Socket.gethostname ()) def saymsg (self, msg): Print "saymsg (" + msg + ")" return "say" + msg + "From" + Socket.gethostbyname (Socket.gethostname ()) handler = HelloWorldHandler () processor = Helloworld.processor (Han Dler) 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!"
 

Writing client 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 * to

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 = Hel Loworld.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)

Running programs

 $ python pythonserver.py $ python pythonclient.py
