Thrift ,[object Object],[object Object],[object Object]

Thrift が使える場面 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Thrift: 各言語が得意な箇所をその言語で実装して RPC で結合

XS や SWIG との違い ,[object Object],[object Object],[object Object],[object Object]

Thrift で RPC の手順 ,[object Object],[object Object],[object Object],[object Object]

1. Thrift IDL でインタフェースを定義 ,[object Object],#!/usr/bin/thrift service Hello { string hello(1: string name) }

2. thrift コマンドでコード生成 ,[object Object],[object Object],% thrift --gen cpp --gen perl hello.thrift % ls -F gen-cpp/ gen-perl/ hello.thrift

サーバーのスケルトン #include "Hello.h" /* 中略 */ class HelloHandler : virtual public HelloIf { public: HelloHandler() { // Your initialization goes here } void hello(std::string& _return, const std::string& name) { // Your implementation goes here printf("hello"); } }; int main(int argc, char **argv) { int port = 9090; 　　 /* ... 以下略 ...*/

3. サーバーを書く ,[object Object],void hello(std::string& _return, const std::string& name) { // Your implementation goes here _return.append("Hello ").append(name); }

サーバーコンパイル , 立ち上げ % g++ -g Hello_server.cpp Hello.cpp > -o Hello_server > -lthrift > -I/usr/local/include/thrift % ./Hello_server

4. Perl でクライアントを書く use lib './gen-perl'; ## Thrift インストール時にインストールされているライブラリ群 use Thrift; use Thrift::BinaryProtocol; use Thrift::Socket; ## IDL から gen-perl/ 以下に生成されたライブラリ use Hello; my $transport = Thrift::Socket->new('localhost', 9090); my $client = HelloClient->new( Thrift::BinaryProtocol->new($transport) ); $transport->open(); printf "%s", $client->hello("naoya") ; $transport->close();

実行 % perl hello.pl Hello, naoya

Ruby でクライアントを書く ,[object Object],[object Object],transport = TBufferedTransport.new(TSocket.new('localhost', 9090)) client = Hello::Client.new( TBinaryProtocol.new(transport)) transport.open puts client.hello("naoya") transport.close
