python thrift搭建服务端和客户端测试程序

 http://www.apache.org/dyn/closer.cgi"htmlcode">

 [root@localhost ~]# yum -y groupinstall "Development Tools"
[root@localhost ~]# yum -y install libevent-devel zlib-devel openssl-devel autoconf automake
[root@localhost ~]# wget http://ftp.gnu.org/gnu/bison/bison-2.5.1.tar.gz 
[root@localhost ~]# tar xf bison-2.5.1.tar.gz
[root@localhost ~]# cd bison-2.5.1
[root@localhost ~]# ./configure --prefix=/usr
[root@localhost ~]# make
[root@localhost ~]# make install
[root@localhost ~]# tar xf thrift-0.9.2.tar.gz 
[root@localhost ~]# cd thrift-0.9.2
[root@localhost thrift-0.9.2]# ./configure -with-lua=no



3.安装python插件


pip install thrift


三、准备服务器端


1.编辑接口文件helloworld.thrift:


#!/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
#创建服务端
handler = HelloWorldHandler()
processor = HelloWorld.Processor(handler)
#监听端口
transport = TSocket.TServerSocket("localhost", 9090)
#选择传输层
tfactory = TTransport.TBufferedTransportFactory()
#选择传输协议
pfactory = TBinaryProtocol.TBinaryProtocolFactory()
#创建服务端 
server = TServer.TSimpleServer(processor, transport, tfactory, pfactory) 
print "Starting thrift server in python..."
server.serve()
print "done!"



四、准备客户端




#!/usr/bin/env python

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

from helloworld import HelloWorld #引入客户端类

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

try:
 #建立socket
 transport = TSocket.TSocket('localhost', 9090)
 #选择传输层，这块要和服务端的设置一致
 transport = TTransport.TBufferedTransport(transport)
 #选择传输协议，这个也要和服务端保持一致，否则无法通信
 protocol = TBinaryProtocol.TBinaryProtocol(transport)
 #创建客户端
 client = HelloWorld.Client(protocol)
 transport.open()

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

 print "client - say"
 msg = client.say("Hello!")
 print "server - " + msg
 #关闭传输
 transport.close()
#捕获异常
except Thrift.TException, ex:
 print "%s" % (ex.message)




PS.这个就是thrift的服务端和客户端的实现小案例。一般只有在多种语言联合开发时才会用到，如果是一种语言的话，thrift就没有用武之地了。在多语言开发时，我们拿到其他语言的thrift文件，就可以直接使用我们的python作为客户端去调用thrift中的函数就可以了，或者我们提供thrift服务端文件供别的语言调用，总起来说还是很方便的，希望上面的例子可以让大家明白thrift的简单应用！
