媒体与资产
包含公开与受保护文件、图片变体与占位符、视频流及处理状态的媒体库。
网站使用的每一张图片、视频和文件都存放在媒体库中。内容通过资产 ID 引用文件,API 响应会将 ID 解析为 URL、尺寸、替代文本和占位符。
核心对象
- 资产 (Assets): 包含文件的可见性、标签、替代文本、焦点和处理状态。公开文件通过 CDN 提供服务。受保护的文件(如课程视频)仅能通过短效签名 URL 访问。
- 图片变体 (Image variants): 按需调整大小的版本,以及每张图片的微型模糊占位符。
- 视频流 (Video streaming): 视频会被转换为自适应流,受保护的视频则使用签名片段。
API 如何运作
- 通过 Management API 使用 URL 或文件上传、请求大文件的直接上传 URL、创建客户端上传链接,以及导入库存照片。
- 每个引用媒体的 Content Delivery API 响应都包含
assets映射表。 - 使用
<kanorio-media>和<kanorio-lightbox>播放媒体并显示图片。 - Webhooks 会报告资产处理完成或失败的状态。
API 开放的范围
- Public & protected media, responsive images, LQIP placeholders, lightbox & HLS video streaming可用
