Thriftudp

中文說明

Thrift是UDP協議的最佳IDL語言之一，因為它的語法支持oneway關鍵字。但是官方軟件包僅支持TCP運輸和服務器框架。

該軟件包的目的是通過UDP支持擴展thrift 。它提供以下功能：

• UDP運輸
• UDP服務器

對於項目，github.com/jaegertracing/jaeger在舊的舊貨版中具有非常漂亮的實現。該項目只需使用其transport實施，並進行了微小的修改以進行新版本支持。

快速開始

請確保已經安裝了Apache/Thrift。

IDL定義

 namespace go echo

struct Request {
    1: string message ;
}

service Echo {
    oneway void Ping( 1: Request request );
}

使用thrift生成框架代碼：

$: cd example
$: thrift -out thrift -r --gen go idl/echo.thrift 

服務器實現

 package main

import (
	"context"
	"log"

	"github.com/x-mod/routine"
	"github.com/x-mod/thriftudp"
	"github.com/x-mod/thriftudp/example/thrift/echo"
)

type echoImpl struct {}

func ( srv * echoImpl ) Ping ( ctx context. Context , request * echo. Request ) ( err error ) {
	log . Println ( "echo Ping Request Message: " , request . Message )
	return nil
}

func main () {
	routine . Main ( context . TODO (), routine . ExecutorFunc ( func ( ctx context. Context ) error {
		srv := thriftudp . NewServer (
			thriftudp . ListenAddress ( "127.0.0.1:8888" ),
			thriftudp . Processor (
				echo . NewEchoProcessor ( & echoImpl {}),
				2 ),
		)
		if err := srv . Open ( ctx ); err != nil {
			return err
		}
		log . Println ( "serving at 127.0.0.1:8888 ..." )
		return srv . Serv ( ctx )
	}))
}
