本文生动简洁介绍了如何通过python搭建一个服务端和客户端的简单测试程序。
一、简介
thrift是一个软件框架,用来进行可扩展且跨语言的服务的开发。它结合了功能强大的软件堆栈和代码生成引擎,以构建在 C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js, Smalltalk, and OCaml 这些编程语言间无缝结合的、高效的服务。
二、安装

[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

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!"

#!/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!
