rubyでamazonからISBNを検索 - Super Neurotic Junction

▼ 2009/06/24(水) rubyでamazonからISBNを検索

2009/06/24 28:58 【研究課題】snjx

日本語ドキュメントがなくてちと悩んだんだけど、結果的にすごい簡単なことだったのでメモしておく。

rubyスクリプトでamazonのWabAPIを利用して、ISBNから書誌情報を取得するサンプル。

■ インストールと設定

まずはライブラリをインストール。

> gem install ruby-aaws

で、実行ディレクトリに、「.amazonrc」という名称で以下の内容のファイルを作成。
実行ディレクトリにキャッシュファイルを作成する設定になっている。

[global]
  key_id        = 'YOURACCESSKEYSTRING'
  secret_key_id = 'YOURSECREDKEYIDSTRINGXXXXXXXXXX'
　associate     = 'YOURASSOCIATEIDSTRING'
  locale        = jp
  cache         = true
  cache_dir     = .

■ サンプルコード作成

適当な名前で以下のコードを作成し、引数に13桁のＩＳＢＮを指定してキックしてやる。

# 事前に > gem install ruby-aaws を実行します。

require 'amazon/aws'
require 'amazon/aws/search'

isbn = ARGV.shift # 第一引数からＩＳＢＮを取得

# 設定ファイルのデフォルトは /etc/amazonrc か ~/.amazonrc
# それ以外の場所に設定をおきたい場合は、以下の環境変数を変更する。
ENV['AMAZONRCDIR']  = '.' # 設定ファイルの位置を変えるときはこれ
# ENV['AMAZONRCFILE'] = 'amazonrc' # 設定ファイルの名称を変えるときはこれ

begin

  # il = Amazon::AWS::ItemLookup.new('ASIN', {'ItemId' => '4063142450'} ) # ASIN指定の場合
  # il = Amazon::AWS::ItemLookup.new('ISBN',{'ItemId' => isbn}),  # ISBNだけどerror　パラメータが足りない
  # il = Amazon::AWS::ItemLookup.new('ISBN',{'ItemId' => '9784797340045','SearchIndex' => 'Books'}) # 間違ったISBNで検索
  il = Amazon::AWS::ItemLookup.new('ISBN',{'ItemId' => isbn,'SearchIndex' => 'Books'})
  rg = Amazon::AWS::ResponseGroup.new( 'Medium' )

  req = Amazon::AWS::Search::Request.new()

  page = req.search(il, rg)

  puts '===================page Analysis'
  puts page.class
  puts '==↑page.class'
  puts page.methods(false)
  puts '==↑page.methods(fase)'
  puts page.inspect
  puts '==↑page.inspect'
  puts page.properties
  puts '==↑page.properties'
  # puts '===================ItemLookup response'
  # puts page
  puts '===================Get ASIN and other data'
  print "ASIN = ",           page.item_lookup_response.items.item.asin ,"\n"
  print "small_image = ",    page.item_lookup_response.items.item.small_image.url,"\n"
  print "medium_image = ",   page.item_lookup_response.items.item.medium_image.url,"\n"
  print "large_image = ",    page.item_lookup_response.items.item.large_image.url,"\n"
  print "detail_page_url = ",page.item_lookup_response.items.item.detail_page_url,"\n"
  print "title = ",          page.item_lookup_response.items.item.item_attributes.title,"\n"
  print "publisher = ",      page.item_lookup_response.items.item.item_attributes.publisher,"\n"
  print "author = ",         page.item_lookup_response.items.item.item_attributes.author,"\n"

rescue SocketError => exp
  # ソケットエラーが出た場合は10秒待ってから、beginより再実行
  print exp.backtrace ,"\n  [", exp.message , "]\n"
  sleep 10
  retry
rescue => exp
 print exp.backtrace ,"\n class=", exp.class , "\n  [", exp.message , "]\n"
end

これで、こんな感じの出力が得られる。
