## YouTube JSON API 这是YouTube JSON API响应对象的示例。你可以从中学到更多关于YouTube JSON API的内容：[http://code.google.com/apis/youtube/2.0/developers_guide_jsonc.html](http://code.google.com/apis/youtube/2.0/developers_guide_jsonc.html) ~~~ { "apiVersion": "2.0", "data": { "updated": "2010-02-04T19:29:54.001Z", "totalItems": 6741, "startIndex": 1, "itemsPerPage": 1, "items": [ { "id": "BGODurRfVv4", "uploaded": "2009-11-17T20:10:06.000Z", "updated": "2010-02-04T06:25:57.000Z", "uploader": "docchat", "category": "Animals", "title": "From service dog to SURFice dog", "description": "Surf dog Ricochets inspirational video ...", "tags": [ "Surf dog", "dog surfing", "dog", "golden retriever", ], "thumbnail": { "default": "http://i.ytimg.com/vi/BGODurRfVv4/default.jpg", "hqDefault": "http://i.ytimg.com/vi/BGODurRfVv4/hqdefault.jpg" }, "player": { "default": "http://www.youtube.com/watch?v=BGODurRfVv4&feature=youtube_gdata", "mobile": "http://m.youtube.com/details?v=BGODurRfVv4" }, "content": { "1": "rtsp://v5.cache6.c.youtube.com/CiILENy73wIaGQn-Vl-0uoNjBBMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp", "5": "http://www.youtube.com/v/BGODurRfVv4?f=videos&app=youtube_gdata", "6": "rtsp://v7.cache7.c.youtube.com/CiILENy73wIaGQn-Vl-0uoNjBBMYESARFEgGUgZ2aWRlb3MM/0/0/0/video.3gp" }, "duration": 315, "rating": 4.96, "ratingCount": 2043, "viewCount": 1781691, "favoriteCount": 3363, "commentCount": 1007, "commentsAllowed": true } ] } } ~~~ ## 分页示例 如何将Google搜索条目作为JSON对象展现出来，对分页变量也有特别关注。 这个示例仅用作说明。下面的API实际上并不存在。 这是Google搜索结果页面的示例： [](https://camo.githubusercontent.com/c8ff0de46d7cb966ddae8b3350960400fdd6962d/687474703a2f2f676f6f676c652d7374796c6567756964652e676f6f676c65636f64652e636f6d2f73766e2f7472756e6b2f6a736f6e637374796c6567756964655f6578616d706c655f30312e706e67) [](https://camo.githubusercontent.com/0341a3abf1faaffd6dc67039efd964336d285f54/687474703a2f2f676f6f676c652d7374796c6567756964652e676f6f676c65636f64652e636f6d2f73766e2f7472756e6b2f6a736f6e637374796c6567756964655f6578616d706c655f30322e706e67) 这是该页面JSON形式的呈现： ~~~ { "apiVersion": "2.1", "id": "1", "data": { "query": "chicago style pizza", "time": "0.1", "currentItemCount": 10, "itemsPerPage": 10, "startIndex": 11, "totalItems": 2700000, "nextLink": "http://www.google.com/search?hl=en&q=chicago+style+pizza&start=20&sa=N" "previousLink": "http://www.google.com/search?hl=en&q=chicago+style+pizza&start=0&sa=N", "pagingLinkTemplate": "http://www.google.com/search/hl=en&q=chicago+style+pizza&start={index}&sa=N", "items": [ { "title": "Pizz'a Chicago Home Page" // More fields for the search results } // More search results ] } } ~~~ 这是如何展现屏幕截图中的色块的例子（背景颜色对应下图中的颜色） * Results 11 - 20 of about 2,700,000 = startIndex * Results 11 - 20 of about 2,700,000 = startIndex + currentItemCount - 1 * Results 11 - 20 of about 2,700,000 = totalItems * Search results = items (formatted appropriately) * Previous/Next = previousLink / nextLink * Numbered links in "Gooooooooooogle" = Derived from "pageLinkTemplate". The developer is responsible for calculating the values for {index} and substituting those values into the "pageLinkTemplate". The pageLinkTemplate's {index} variable is calculated as follows: * Index #1 = 0 * itemsPerPage = 0 * Index #2 = 2 * itemsPerPage = 10 * Index #3 = 3 * itemsPerPage = 20 * Index #N = N * itemsPerPage
