在为有声读物禁用的曲目中寻找

Question

我们正在尝试构建一个 API 来在 Sonos 上播放有声读物，我们已经运行解决了一个问题，即对于有声读物类型的容器，似乎专门禁用了通过曲目进行搜索的问题。当我们将容器类型设置为 'container' 时，我们注意到了这个问题，发现不仅可以在轨道周围搜索，而且 "Quick Skips," 也可以，这应该只适用于有声读物和播客（https://developer.sonos.com/build/content-service-get-started/supported-audio-content/).

Here is what playback looks like when the container type for our chapter tracks is set to 'audiobook' and here's what it looks like 当容器类型设置为 'container.' 为什么我们要运行解决这个问题，有什么方法可以允许在轨道内搜索和快速跳过有声读物容器中的曲目？

以下是我们服务的 getMetadata 响应示例。

                    <title>The Grapes of Wrath</title>
                    <summary>First published in 1939, The Grapes of Wrath creates an unforgettable portrait of the migrants who left the dust bowl for the promised land of California. Although he wrote it quickly, Steinbeck spent much time gathering detailed reports of the desperate conditions in migrant camps. He also worked in one camp helping to care for its starving residents. Although they have planted the land for generations, the Joads are tenant farmers. Now drought and mechanization have forced them off the Oklahoma farm they call home. As they travel toward new jobs in California, the penniless, hungry Joads learn that America has no mercy for the poor. Their fate is one that was repeated in hundreds of lives. Brilliant in its fusion of drama and rhetoric, The Grapes of Wrath changed the way the world saw migrant workers. They would never again be faceless masses who could be ignored and abandoned. This landmark work's impact earned John Steinbeck the Pulitzer Prize and contributed...</summary>

为了有声读物的搜索工作，我们是否必须包含任何其他参数？

Answer 1

您似乎缺少 trackMetadata 中的 duration 元素。为通用 container itemType 显示快速跳过按钮的事实是无意的。

当元数据包含作者、旁白或章节标题时，Sonos 应用程序会显示有声读物的快速跳过，前提是您：

将 audioBook 指定为 itemType。
在每个章节的 trackMetadata 中包含 duration。

见Saving and Resuming Play Position 了解详情。
