簡介
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是一個軟體框架，用來進行可擴展跨語言的服務開發，結合了軟體堆棧和代碼生成引擎，用來構建C++,Java,Python...等語言，使之它們之間無縫結合、高效服務。
安裝
brew install thrift
作用
跨語言調用，打破不同語言之間的隔閡。跨項目調用，微服務的麼麼噠。
示例
前提
thrift版本：
Go的版本、Php版本、Python版本：
說明
該示例包含python,php,go三種語言。（java暫無）
新建HelloThrift.thrift
進入目錄
cd /Users/birjemin/Developer/Php/study-php
編寫HelloThrift.thrift
vim HelloThrift.thrift
內容如下：
namespace php HelloThrift {
string SayHello(1:string username)
}
Php測試
加載thrift-php庫
composer require apache/thrift
生成php版本的thrift相關文件
cd /Users/birjemin/Developer/Php/study-php
thrift -r --gen php:server HelloThrift.thrift
這時目錄中生成了一個叫做gen-php的目錄。
建立Server.php文件
<?php
/**
* 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
<?php
/**
* 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();
測試
php Client.php --http
Python測試
加載thrift-python3模塊（只測試python3,python2就不測試了）
pip3 install thrift
生成python3版本的thrift相關文件
thrift -r --gen py HelloThrift.thrift
這時目錄中生成了一個叫做gen-py的目錄。
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()
測試開一個新窗口，運行下面命令：python3 Server.php
Go測試
加載go的thrift模塊
go get git.apache.org/thrift.git/lib/go/thrift
生成go版本的thrift相關文件
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)
}
測試開一個新窗口，運行下面命令：go run Server.go
綜合測試
開啟兩個窗口，保證server開啟
go run Server.go # localhost:9092
python3 Server.py # localhost:9091
php調用go-server、py-server
php Client.php localhost:9091
php Client.php localhost:9092
python3調用go-server、py-server
python3 Client.py localhost:9091
python3 Client.py localhost:9092
go調用go-server、py-server
go run Client.go localhost:9091
go run Client.go localhost:9092
備註
沒有測試php的socket，go、python3的http，可以花時間做一下代碼純屬組裝，沒有深刻了解其中原理，後期打算寫一篇理論篇和封裝類庫篇
