摘要：安裝作用跨語言調用，打破不同語言之間的隔閡。跨項目調用，微服務的么么噠。示例前提版本的版本版本版本說明該示例包含三種語言。

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是一個軟件框架，用來進行可擴展跨語言的服務開發，結合了軟件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。

brew install thrift

跨語言調用，打破不同語言之間的隔閡。
跨項目調用，微服務的么么噠。

thrift版本：

Go的版本、Php版本、Python版本：

該示例包含python,php,go三種語言。（java暫無）

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)
}

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

registerDefinition("HelloThrift",$GEN_DIR);
$loader->register();

class HelloHandler implements HelloThriftHelloServiceIf
{
    public function SayHello($username)
    {
        return "Php-Server: " . $username;
    }
}

$handler   = new HelloHandler();
$processor = new HelloThriftHelloServiceProcessor($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

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);
$client    = new HelloThriftHelloServiceClient($protocol);
$transport->open();
echo $client->SayHello("Php-Client");
$transport->close();

測試

php Client.php --http

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

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

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

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，后期打算寫一篇理論篇和封裝類庫篇
