YahooJapanのauctionAPIを検索するクラス

Services_Amazonを参考にServices_Yahoo_Auctionを書いてみようかな。ためしにClassかいてみた。PHP5のレフレクションとSimpleXML使うと結構簡単だった。ただ、これだけじゃ、Yahooマッシュアップコンテストに応募できないからなぁ。

Services_Amazonを見ていて思ったのだけれど。なぜCache_HTTP_Requestを使わないのだろう。WebAPIにアクセスするのにキャッシュを挿んで、レスポンス向上図るのに、いちいちCache制御書くの面倒。Cache_HTTP_Requestでとっても楽チン。
