python thrift 服务端与客户
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
Http://www.apache.org/dyn/closer.cgi?path=/thrift/0.9.2/thrift-0.9.2.tar.gz
2.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
pip install thrift
三、准备服务器端
1.编辑接口文件 helloworld.thrift:
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
