YouTube JSON API

以下是 YouTube JSON API 响应对象的示例。你可以在这里了解更多关于 YouTube JSON API 的信息：https://code.google.com/apis/youtube/2.0/developers_guide_jsonc.html 。

分页示例

此示例演示了 Google 搜索项目如何表示为 JSON 对象，特别关注分页变量。

此示例仅用于说明目的。以下 API 实际上并不存在。 以下是 Google 搜索结果页面示例： 以下是此页面的 JSON 表示示例：

{
  "apiVersion": "2.1",
  "id": "1",
  "data": {
    "query": "chicago style pizza",
    "time": "0.1",
    "currentItemCount": 10,
    "itemsPerPage": 10,
    "startIndex": 11,
    "totalItems": 2700000,
    "nextLink": "https://www.google.com/search?hl=en&q=chicago+style+pizza&start=20&sa=N",
    "previousLink": "https://www.google.com/search?hl=en&q=chicago+style+pizza&start=0&sa=N",
    "pagingLinkTemplate": "https://www.google.com/search/hl=en&q=chicago+style+pizza&start={index}&sa=N",
    "items": [
      {
        "title": "Pizz'a Chicago Home Page"
        // 更多搜索结果字段
      }
      // 更多搜索结果
    ]
  }
}

以下是截图中每个彩色框的对应表示（背景颜色对应上面图片中的颜色）：

  • 结果 11 - 20，共约 2,700,000 = startIndex
  • 结果 11 - 20，共约 2,700,000 = startIndex + currentItemCount - 1
  • 结果 11 - 20，共约 2,700,000 = totalItems
  • 搜索结果 = items（适当格式化）
  • 上一页/下一页 = previousLink / nextLink
  • “Gooooooooooogle” 中的编号链接 = 从 pageLinkTemplate 派生。开发者负责计算 {index} 的值并将这些值替换到 pageLinkTemplate 中。pageLinkTemplate 的 {index} 变量计算如下：
    • 索引 #1 = 0 * itemsPerPage = 0
    • 索引 #2 = 2 * itemsPerPage = 10
    • 索引 #3 = 3 * itemsPerPage = 20
    • 索引 #N = N * itemsPerPage
