笔记:Ubuntu下快速开始使用Python Thrift

本文介绍如何在Ubuntu 10.04下安装Apache Thrift并用Python写一个Demo。

apt-get install libboost-dev libevent-dev python-dev automake pkg-config libtool flex bison sun-java6-jdk
wget http://www.apache.org/dist//thrift/0.8.0/thrift-0.8.0.tar.gz
tar zxvf thrift-0.8.0.tar.gz
cd thrift-0.8.0
./configure
make
sudo make install
sudo pip install thrift

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)
thrift --gen py helloworld.thrift
python server.py
python client.py

    使用这个py服务端,java的客户端时有问题!

    py服务器运行后使用netstat -na | grep 9090
    transport = TSocket.TServerSocket(“localhost”, 9090)
    此对应输出为:tcp 0 0 ::1:9090 :::* LISTEN

    此时用java的客户端时显示Connection refuse!
    应改为transport = TSocket.TServerSocket(port= 9090)
    此对应输出为:tcp        0      0 :::9090                     :::*                        LISTEN

    这样java客户端才能正常连接到,原因表现为不同的ip在监听,但根本原因是什么还不了解,希望知道的指导一下! 

    • 执行以下下面的命令看一眼?

      sudo cat /etc/hosts
