Apache Thrift的简单使用

Thrift是Facebook的一个开源项目，主要是一个跨语言的服务开发框架。它有一个代码生成器来对它所定义的IDL定义文件自动生成服务代码框架。用户只要在其之前进行二次开发就行，对于底层的RPC通讯等都是透明的。目前它支持的语言有C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, Smalltalk, and OCaml.

下载安装

可以在http://www.apache.org/dyn/closer.cgi?path=/thrift/0.9.3/thrift-0.9.3.tar.gz 去下载新版本
在安装thrift之前有一些依赖要先安装
* libssl-dev
* automake
* libtool

sudo apt-get install libssl-dev automake libtool

ubuntu系统下使用以上命令即可安装，接下来可以进行编译,安装

./bootstrap.sh./configuremakesudo make install

安装过程的一些问题
1. flex: command not found
bash
solution: sudo apt-get install flex

2. yacc: command not found
bash
solution: sudo apt-get install byacc

安装完成可以用以下命令查看thrift版本

(pyleus27Env)rdy@cherry:~/thrift-work/gen-py$ thrift -versionThrift version 0.9.3 

一个小列子

vim helloworld.thriftservice HelloWorld {    string getservtime(1:string clientname)}

thrift -r --gen py helloworld.thrift // -r对其中include的文件也生成服务代码 -gen是生成服务代码的语言 

生成的代码在gen-py目录下。
创建server.py文件
server.py

#!/usr/bin/env pythonimport socketimport sysimport timesys.path.append('./gen-py')from helloworld import HelloWorldfrom helloworld.ttypes import *from thrift.transport import TSocketfrom thrift.transport import TTransportfrom thrift.protocol import TBinaryProtocolfrom thrift.server import TServerclass HelloWorldHandler:  def getservtime(self, clientname):       return time.strftime( '%Y-%m-%d %H:%M:%S', time.localtime() )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!"

client.py

#!/usr/bin/env pythonimport syssys.path.append('./gen-py')from helloworld import HelloWorldfrom thrift import Thriftfrom thrift.transport import TSocketfrom thrift.transport import TTransportfrom thrift.protocol import TBinaryProtocoltry:  transport = TSocket.TSocket('localhost', 9090)  transport = TTransport.TBufferedTransport(transport)  protocol = TBinaryProtocol.TBinaryProtocol(transport)  client = HelloWorld.Client(protocol)  transport.open()  print "client - get serv time"  print "server - " + client.getservtime('testclient')  transport.close()except Thrift.TException, ex:  print "%s" % (ex.message)

这里主要用到了python的thrift库，目前支持python2.X
切换运行环境

source /home/rdy/virtualENv/pyleus27Env/bin/activate(pyleus27Env)rdy@cherry:~/thrift-work/gen-py$

执行服务端代码

(pyleus27Env)rdy@cherry:~/thrift-work/gen-py$ python server.py Starting thrift server in python...

执行客户端程序

(pyleus27Env)rdy@cherry:~/thrift-work/gen-py$ python client.py client - get serv timeserver - 2016-03-16 10:57:01

其他代码实现

在thrift源码tutorial目录中有其它代码的例子，如erl,java,c++,perl,ruby等。
