Google有一个API for YouTube,可让您轻松地从Windows Phone设备执行此任务。根据Google的网站:
关于Google Data API
Data API允许程序执行YouTube网站上提供的许多操作。可以搜索视频,检索标准供稿以及查看相关内容。程序还可以作为用户进行身份验证,以上传视频,修改用户播放列表等。
Data API主要面向使用服务器端语言编程的开发人员。它对于希望与YouTube进行深度集成的网站或应用程序非常有用,例如可以捕获视频并允许用户将该视频直接上传到YouTube的应用。通过Data API,您可以对YouTube视频和用户信息进行编程访问,使您能够使用用户的现有信息对您的应用进行个性化设置,并代表他们对视频进行评级或评论。
开发人员指南使用XML和HTTP解释 Data API在基本级别的工作方式。本指南详细介绍了YouTube API服务器期望和返回的请求和响应。参考指南提供了有关这些请求和响应的结构的更多详细信息。参考指南定义了API的提要类型,HTTP请求参数,HTTP响应代码和XML元素。您可能还想了解Google数据协议和Atom发布协议,它们是构建Data API的标准。
为了更容易地使用API,我们有许多客户端库将API抽象为特定于语言的对象模型。这些客户端库是开源的,可以在Apache License 2.0下使用和修改。有 Java , .NET , PHP 和 Python 的开发人员指南以及示例代码。
浏览此页YouTube API v2.0 - Understanding Feeds and Entries,其中说明:
当您检索视频供稿或搜索结果列表时,YouTube会返回一个Atom供稿,其中包含结果集中每个视频的一个标记。响应中的根XML标记将是标记。除了有关结果集中各个视频的信息之外,Feed还将包含列表中的结果总数,列表中第一个项目的索引,列表中的项目数以及有关该列表的其他元数据。进料。
以下XML显示了包含视频供稿的YouTube数据API响应的格式:

作为替代方案,可以通过解析DOM来使用HTML Agility Pack完成此操作,但是您应该先探索上述解决方案,然后再进入DOM解析和/或将其与Google YouTube结合使用API。
