thrift-Simple and practical

This is a creation in Article, where the information may have evolved or changed.

Brief introduction

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 is a software framework for extensible cross-language service development combined with a software stack and code generation engine to build C++,java,python ... and other languages, so that they seamlessly combine and efficiently serve.

Installation

brew install thrift

Role

cross-language calls to break the gap between different languages.
Cross-project calls, MicroServices of the DA.

Example

Premise

• Thrift Version:

• Go version, PHP version, Python version:

Description

The example contains Python,php,go in three languages. (Java temporarily none)

New Hellothrift.thrift

• Go to Catalog

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

• Writing Hellothrift.thrift

vim HelloThrift.thrift

The contents are as follows:

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

PHP test

• Loading the thrift-php library

composer require apache/thrift

• Generate PHP version of thrift related files

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

The directory is then generated with a directory called gen-php .

• establishing a server.php file

  <?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) {R Eturn "Php-server:".    $username; }} $handler = new Hellohandler (), $processor = new \hellothrift\helloserviceprocessor ($handler); $transport = new Tbuffere Dtransport (New Tphpstream (Tphpstream::mode_r | TPHPSTREAM::MODE_W); $protocol = new Tbinaryprotocol ($transport, true,true); $transport->open (); $processor Process ($protocol, $protocol); $transport->close ();  

• establishing a client.php file

  <?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 ', '/server.php ');} el    se {$host = explode (":", $argv [1]); $socket = new Tsocket ($host [0], $host [1]);} $transport = new Tbufferedtransport ($socket, 1024,1024), $protocol = new Tbinaryprotocol ($transport); $client = new \hell Othrift\helloserviceclient ($protocol); $transport->open (); Echo $client->sayhello ("php-client"); $transport- >close ();  

• Test

php Client.php --http

Python test

• Load the Thrift-python3 module (test python3,python2 is not tested)

pip3 install thrift

• Generate Python3 version of thrift related files

thrift -r --gen py HelloThrift.thrift

The directory is then generated with a directory called gen-py .

• Create a Server.py file

#!/usr/bin/python3# -*- coding: UTF-8 -*-import syssys.path.append('./gen-py')from HelloThrift import HelloServicefrom HelloThrift.ttypes import *from thrift.transport import TSocketfrom thrift.transport import TTransportfrom thrift.protocol import TBinaryProtocolfrom thrift.server import TServerclass HelloWorldHandler:    def __init__(self):        self.log = {}    def SayHello(self, user_name = ""):        return "Python-Server: " + user_namehandler = 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()

• Create a Client.py file

#!/usr/bin/python3# -*- coding: UTF-8 -*-import syssys.path.append('./gen-py')from HelloThrift import HelloServicefrom HelloThrift.ttypes import *from HelloThrift.constants import *from thrift.transport import TSocketfrom thrift.transport import TTransportfrom thrift.protocol import TBinaryProtocolhost = 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()

• Test

Open a new window and run the following command:

python3 Server.php

Go test

• Load the Go Thrift module

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

• Generate thrift related files for Go version

thrift -r --gen go HelloThrift.thrift

• Generating Server.go files

package mainimport (    "./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()}

• Generating Client.go files

package mainimport (    "./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)}

• Test

Open a new window and run the following command:

go run Server.go

Comprehensive testing

• Open two windows to ensure server is turned on

go run Server.go # localhost:9092python3 Server.py # localhost:9091

• PHP calls Go-server, Py-server

php Client.php localhost:9091php Client.php localhost:9092

• Python3 calls Go-server, Py-server

python3 Client.py localhost:9091python3 Client.py localhost:9092

• Go calls Go-server, Py-server

go run Client.go localhost:9091go run Client.go localhost:9092

Note

1. Without testing PHP's Socket,go, Python3 http, you can take the time to do
2. The code is purely assembled, without a deep understanding of the principles, and later intends to write a theoretical and encapsulated class library
