如何从 Spotify 获取当前用户的播放列表

Question

我正在尝试将 Spotify 与当前用户的播放列表集成以将其显示在我的表格视图中。我已经集成了登录和访问令牌，一切正常。我已经通过堆栈溢出链接：- How to get the list of songs using Spotify in Swift3 iOS? 但对我不起作用。

然后打印 canonicalUsername 如下，它显示 nil 值

SPTUser.requestCurrentUser(withAccessToken:(SPTAuth.defaultInstance().session.accessToken)!) { (error, data) in
        guard let user = data as? SPTUser else { print("Couldn't cast as SPTUser"); return }
        let userId = user.canonicalUsername
})

我什至尝试过这个链接Spotify iOS SDK Swift display all (!) playlists (20+)，因为初学者可能对我也不起作用。有什么方法可以获取 Spotify 的当前用户 ID？如何在表格视图中显示当前用户的播放列表？

根据您的问题，获取打印 canonicalUsername 或当前用户 ID 的解决方案尝试如下，

 SPTUser.requestCurrentUser(withAccessToken: session.accessToken) { (error, data) in
                    guard let user = data as? SPTUser else { print("Couldn't cast as SPTUser"); return }
                    let userID = user.canonicalUserName

                 print(userID!)
                 }   

然后要获取当前用户的播放列表并在您的设备中播放，首先调用视图控制器中的 SPT Delegate，然后调用函数，

class PlayVC: UIViewController, SPTAudioStreamingDelegate, SPTAudioStreamingPlaybackDelegate {
func audioStreamingDidLogin(_ audioStreaming: SPTAudioStreamingController) {
        let playListRequest = try! SPTPlaylistList.createRequestForGettingPlaylists(forUser: session.canonicalUsername, withAccessToken: session.accessToken)
        Alamofire.request(playListRequest)
            .response { response in
                let list = try! SPTPlaylistList(from: response.data, with: response.response)

                for playList in list.items  {
                    if let playlist = playList as? SPTPartialPlaylist {
                        print( playlist.name! ) // playlist name
                        print( playlist.uri!)    // playlist uri
                      // self.tableView.reloadData()// if u want to display playlist name and other stuffs like so..
                        SPTAudioStreamingController.sharedInstance().playSpotifyURI("\(playlist.uri!)", startingWith: 0, startingWithPosition: 10) { error in
                            if error != nil {
                                print("*** failed to play: \(error)")
                                return
                            }
                        }
                        }}}

    }
}
