我有一个有两页的小应用程序。登录页面之后，第一页是一个目录，其中包含视频列表，用户可以从中选择自己选择的YouTube视频。当用户从侧边栏菜单中选择视频时，他们将被带到视频播放的页面，我将其包含在下面的代码中。这个应用程序使用xAPI Youtube视频跟踪 - 在Github上的ADL，它基本上做广告发送任何数量的语句，如启动，暂停，恢复和完成。但问题是，它并不总是发送＆＃34;启动＆＃34;声明。例如，如果我预览视频并确定它是我想要的视频，我将对其进行编码。然后，如果我以John Doe身份登录并播放它，则第一个语句是＆＃34; resume。＆＃ 34;这是因为我自己预览了视频而youtube以某种方式记得这个吗？我的代码下面是否有引起这种情况的原因？如果我在没有预览的情况下对youtube视频进行编码，它似乎会按照人们的预期发送一个启动语句。谢谢。
