python thrift 服务端与客户端使用

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
    1.下载地址   

1
http://www.apache.org/dyn/closer.cgi?path=/thrift/0.9.2/thrift-0.9.2.tar.gz




    2.安装

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




    3.安装python插件


1
pip install thrift




三、准备服务器端
    1.编辑接口文件 helloworld.thrift:

1

4
service HelloWorld {
    string ping(),
    string say(1:string msg)
}




    2.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
#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：亲测通过，吐槽一下，这东西以前都没有听说过，就要拿来开发，还要只是用客户端
