Thrift-简单使用

简介

The Apache Thrift software framework, for scalable cross-language services development, combines a software stack with a code generation engine to build services that work efficiently and seamlessly between C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js, Smalltalk, OCaml and Delphi and other languages.

Apache Thrift是一个软件框架,用来进行可扩展跨语言的服务开发,结合了软件堆栈和代码生成引擎,用来构建C++,Java,Python...等语言,使之它们之间无缝结合、高效服务。

安装

brew install thrift

作用

跨语言调用,打破不同语言之间的隔阂。

跨项目调用,微服务的么么哒。

前提

thrift版本:

Go的版本、Php版本、Python版本:

说明

该示例包含python,php,go三种语言。(java暂无)

新建HelloThrift.thrift

进入目录

cd /Users/birjemin/Developer/Php/study-php

编写HelloThrift.thrift

vim HelloThrift.thrift

内容如下:

namespace php HelloThrift { string SayHello(1:string username) }

Php测试

加载thrift-php库

composer require apache/thrift

生成php版本的thrift相关文件

cd /Users/birjemin/Developer/Php/study-php thrift -r --gen php:server HelloThrift.thrift

这时目录中生成了一个叫做gen-php的目录。

建立Server.php文件

/** * Created by PhpStorm.

* User: birjemin

* Date: 22/02/2018

* Time: 3:59 PM

*/

namespace HelloThrift\php;require_once 'vendor/autoload.php';

use Thrift\ClassLoader\ThriftClassLoader;

use Thrift\Protocol\TBinaryProtocol;

use Thrift\Transport\TPhpStream;

use Thrift\Transport\TBufferedTransport;

$GEN_DIR = realpath(dirname(__FILE__)).'/gen-php';

$loader = new ThriftClassLoader();

$loader->registerDefinition('HelloThrift',$GEN_DIR);

$loader->register();

class HelloHandler implements \HelloThrift\HelloServiceIf{

public function SayHello($username) {

return "Php-Server: " . $username;

}

}

$handler = new HelloHandler();

$processor = new \HelloThrift\HelloServiceProcessor($handler);

$transport = new TBufferedTransport(new TPhpStream(TPhpStream::MODE_R | TPhpStream::MODE_W));

$protocol = new TBinaryProtocol($transport,true,true);

$transport->open();

$processor->process($protocol,$protocol);

$transport->close();

建立Client.php文件

/** * Created by PhpStorm.

* User: birjemin

* Date: 22/02/2018

* Time: 4:00 PM

*/

namespace HelloThrift\php;

require_once 'vendor/autoload.php';

use Thrift\ClassLoader\ThriftClassLoader;

use Thrift\Protocol\TBinaryProtocol;

use Thrift\Transport\TSocket;

use Thrift\Transport\THttpClient;

use Thrift\Transport\TBufferedTransport;

use Thrift\Exception\TException;

$GEN_DIR = realpath(dirname(__FILE__)).'/gen-php';

$loader = new ThriftClassLoader();

$loader->registerDefinition('HelloThrift', $GEN_DIR);

$loader->register();

if (array_search('--http',$argv)) {

$socket = new THttpClient('local.study-php.com', 80,'/Server.php');

} else {

$host = explode(":", $argv[1]);

$socket = new TSocket($host[0], $host[1]);

}

$transport = new TBufferedTransport($socket,1024,1024);

$protocol = new TBinaryProtocol($transport);

$client = new \HelloThrift\HelloServiceClient($protocol);

$transport->open();

echo $client->SayHello("Php-Client");

$transport->close();

测试

php Client.php --http

Python测试

加载thrift-python3模块(只测试python3,python2就不测试了)

pip3 install thrift

生成python3版本的thrift相关文件

thrift -r --gen py HelloThrift.thrift

这时目录中生成了一个叫做gen-py的目录。

建立Server.py文件

#!/usr/bin/python3

# -*- coding: UTF-8 -*-

import sys

sys.path.append('./gen-py')

from HelloThrift import HelloService

from HelloThrift.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 __init__(self):

self.log = {}

def SayHello(self, user_name = ""):

return "Python-Server: " + user_name

handler = HelloWorldHandler()

processor = HelloService.Processor(handler)

transport = TSocket.TServerSocket('localhost', 9091)

tfactory = TTransport.TBufferedTransportFactory()

pfactory = TBinaryProtocol.TBinaryProtocolFactory()

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

server.serve()

建立Client.py文件

#!/usr/bin/python3

# -*- coding: UTF-8 -*-

import sys

sys.path.append('./gen-py')

from HelloThrift import HelloService

from HelloThrift.ttypes import *

from HelloThrift.constants import *

from thrift.transport import TSocket

from thrift.transport import TTransport

from thrift.protocol import TBinaryProtocol

host = sys.argv[1].split(':')

transport = TSocket.TSocket(host[0], host[1])

transport = TTransport.TBufferedTransport(transport)

protocol = TBinaryProtocol.TBinaryProtocol(transport)

client = HelloService.Client(protocol)

transport.open()

msg = client.SayHello('Python-Client')

print(msg)

transport.close()

测试

开一个新窗口,运行下面命令:

python3 Server.php

Go测试

加载go的thrift模块

go get git.apache.org/thrift.git/lib/go/thrift

生成go版本的thrift相关文件

thrift -r --gen go HelloThrift.thrift

生成Server.go文件

package main

import (

"./gen-go/hellothrift"

"git.apache.org/thrift.git/lib/go/thrift"

"context")

const (

NET_WORK_ADDR = "localhost:9092"

)

type HelloServiceTmpl struct { }

func (this *HelloServiceTmpl) SayHello(ctx context.Context, str string) (s string, err error) {

return "Go-Server:" + str, nil

}

func main() {

transportFactory := thrift.NewTTransportFactory()

protocolFactory := thrift.NewTBinaryProtocolFactoryDefault()

transportFactory = thrift.NewTBufferedTransportFactory(8192)

transport, _ := thrift.NewTServerSocket(NET_WORK_ADDR)

handler := &HelloServiceTmpl{}

processor := hellothrift.NewHelloServiceProcessor(handler)

server := thrift.NewTSimpleServer4(processor, transport, transportFactory, protocolFactory)

server.Serve()

}

生成Client.go文件

package main

import (

"./gen-go/hellothrift"

"git.apache.org/thrift.git/lib/go/thrift"

"fmt"

"context"

"os"

)

func main() {

var transport thrift.TTransport

args := os.Args

protocolFactory := thrift.NewTBinaryProtocolFactoryDefault()

transport, _ = thrift.NewTSocket(args[1])

transportFactory := thrift.NewTBufferedTransportFactory(8192)

transport, _ = transportFactory.GetTransport(transport)

//defer transport.Close()

transport.Open()

client := hellothrift.NewHelloServiceClientFactory(transport, protocolFactory)

str, _ := client.SayHello(context.Background(), "Go-Client")

fmt.Println(str)

}

测试

开一个新窗口,运行下面命令:

go run Server.go

综合测试

开启两个窗口,保证server开启

go run Server.go # localhost:9092

python3 Server.py # localhost:9091

php调用go-server、py-server

php Client.php localhost:9091

php Client.php localhost:9092

python3调用go-server、py-server

python3 Client.py localhost:9091

python3 Client.py localhost:9092

go调用go-server、py-server

go run Client.go localhost:9091

go run Client.go localhost:9092

备注

没有测试php的socket,go、python3的http,可以花时间做一下

代码纯属组装,没有深刻了解其中原理,后期打算写一篇理论篇和封装类库篇
