附加到Spotify播放列表(Append to Spotify playlist)

附加到Spotify播放列表(Append to Spotify playlist)

API v1，Spotify v 0.9.4.185

我似乎无法将歌曲添加到播放列表中。

这有效：

playlist.tracks.insert(playlist_tracks.ref(playlist_tracks.length-1), tracks_to_append)

这不是：

playlist.tracks.insert(playlist_tracks.ref(playlist_tracks.length), tracks_to_append)

后者的失败回调称“不是轨道URI”。 在err.message中

API v1, Spotify v 0.9.4.185

I don't seem to be able to append songs to a playlist.

This works:

playlist.tracks.insert(playlist_tracks.ref(playlist_tracks.length-1), tracks_to_append)

This doesn't:

playlist.tracks.insert(playlist_tracks.ref(playlist_tracks.length), tracks_to_append)

fail callback for the latter says " is not a track URI." in err.message

最满意答案

那么，根据文档，我的代码应该工作。 但是，我忽略了Collection的add方法。 感谢irc上的ocip。

Well, based on the documentation, my code should work. However, I overlooked the add method of Collection. Thanks to ocip on irc.
