python thrift 服务端与客户端使用

lkoih

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

1 2 3 4 5 6 7 8 9 10 11

[iyunv@localhost ~]# yum -y groupinstall "Development Tools" [iyunv@localhost ~]# yum -y install libevent-devel zlib-devel openssl-devel autoconf automake [iyunv@localhost ~]#  wget http://ftp.gnu.org/gnu/bison/bison-2.5.1.tar.gz [iyunv@localhost ~]# tar xf bison-2.5.1.tar.gz [iyunv@localhost ~]# cd bison-2.5.1 [iyunv@localhost ~]# ./configure --prefix=/usr [iyunv@localhost ~]# make [iyunv@localhost ~]# make install [iyunv@localhost ~]# tar xf thrift-0.9.2.tar.gz [iyunv@localhost ~]# cd thrift-0.9.2 [iyunv@localhost 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 2 3 4

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

    2.编辑 server.py

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

#!/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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

#!/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
