用 SuperObject 解析淘宝上的 Json 数据

macrolen 给了这样一些数据, 说是用淘宝的 API 获取的 JSON 数据, 让我帮助解析:

{"items_search_response":{"item_search":{"item_categories":{"item_category":[{"category_id":150708,"count":66},{"category_id":50002480,"count":93},{"category_id":50006247,"count":164},{"category_id":50012579,"count":19518},{"category_id":50012018,"count":92},{"category_id":150704,"count":10527},{"category_id":150705,"count":226},{"category_id":150706,"count":604},{"category_id":50005050,"count":2900},{"category_id":50011418,"count":94},{"category_id":50012587,"count":6711},{"category_id":50012584,"count":14661},{"category_id":50011150,"count":3058},{"category_id":50008194,"count":72},{"category_id":50010259,"count":348},{"category_id":50008681,"count":251},{"category_id":50003774,"count":252},{"category_id":50003775,"count":7022},{"category_id":150701,"count":802},{"category_id":50012010,"count":134},{"category_id":50008202,"count":68},{"category_id":3412,"count":1125},{"category_id":50005787,"count":127},{"category_id":50002928,"count":158},{"category_id":50014945,"count":113},{"category_id":50010614,"count":2120},{"category_id":140908,"count":122},{"category_id":50003781,"count":349},{"category_id":50008734,"count":755},{"category_id":50002887,"count":114},{"category_id":50003853,"count":252},{"category_id":50005266,"count":2490},{"category_id":50003327,"count":1326},{"category_id":50008169,"count":562},{"category_id":1205,"count":202},{"category_id":50008096,"count":66},{"category_id":50005729,"count":752},{"category_id":50012166,"count":176},{"category_id":1512,"count":107960},{"category_id":111005,"count":330}]},"items":{"item":[{"cid":150701,"delist_time":"2010-01-20

另外 SuperObject 当前的最新版本是: SuperObjectv1.2.3, 还没有测试它新增的功能, 不过我这个是用它做的.
