thrift服务端到客户端开发简单示例

(1)首先我们在服务器端写个helloworld.thrift文件，如下所示：

service HelloWorld{
string ping(1: string name),
string getpng(),
}

(2)在服务器端编译helloworld.thrift
编译helloworld.thrift文件，会产生服务器端和客户端相应语言的接口源码。
/usr/local/thrift/bin/thrift -r --gen py helloworld.thrift
/usr/local/thrift/bin/thrift -r --gen php helloworld.thrift
#会在当前目录下生成 gen-* 目录。
产生的gen-py目录放在服务器上，产生的gen-php目录放在客户端上。

(3)编写服务器端代码

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 HellowordHandler:
def __init__ (self):
pass

def ping (self, name):
print name + ‘ from server.‘
return "%s from server." % name
def getpng (self):
f = open("./logo.png", "rb")
c = f.read()
f.close()
return c
handler = HellowordHandler()
processor = HelloWorld.Processor(handler)
transport = TSocket.TServerSocket(9090)
tfactory = TTransport.TBufferedTransportFactory()
pfactory = TBinaryProtocol.TBinaryProtocolFactory()

server = TServer.TSimpleServer(processor, transport, tfactory, pfactory)

# You could do one of these for a multithreaded server
#server = TServer.TThreadedServer(processor, transport, tfactory, pfactory)
#server = TServer.TThreadPoolServer(processor, transport, tfactory, pfactory)

print ‘Starting the server...‘
server.serve()
print ‘done.‘

(4)编写客户端代码
先将gen-php目录拷贝到客户端上。

<?php
try{
//包含thrift客户端库文件
$GLOBALS[‘THRIFT_ROOT‘] = ‘/root/thrift-0.9.0/lib/php/lib/Thrift‘;
require_once ‘/root/thrift-0.9.0/lib/php/src/Thrift.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Protocol/TBinaryProtocol.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Transport/TSocket.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Transport/THttpClient.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Transport/TBufferedTransport.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Type/TType.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Type/TMessageType.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Factory/TStringFuncFactory.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/StringFunc/TStringFunc.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/StringFunc/Core.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Exception/TException.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Exception/TProtocolException.php‘;
require_once $GLOBALS[‘THRIFT_ROOT‘].‘/Exception/TTransportException.php‘;

error_reporting(E_NONE);

//包含helloworld接口文件
$GEN_DIR = ‘./gen-php‘;
require_once $GEN_DIR.‘/helloworld/HelloWorld.php‘;

error_reporting(E_ALL);

$socket = new TSocket(‘*.*.*.*‘, 9090);
$transport = new TBufferedTransport($socket, 1024, 1024);
$protocol = new TBinaryProtocol($transport);
$client = new HelloWorldClient($protocol);

$transport->open();

$a = $client->ping(‘xyq ‘);
echo $a;

$transport->close();

}catch(TException $tx){
print ‘TException: ‘.$tx->getMessage()."/n";
}

?>
