XCDYouTubeKit + YouTube authentication?

[XRadevFRT]

Greeting every on and great job 0xced,

I'm just wondering...can this library co-work with the youtube authentication. Of course the idea is to fetch and play your videos after you log in in your youtube account. I haven't implemented it yet, but just wondering.

Having the same problem loading the captions https://developers.google.com/youtube/v3/docs/captions/download. This requires a login.

As XCDYouTubeKit contains + (instancetype)queryForCaptionsDownloadWithIdentifier:(NSString *)identifier;

the must be a way to authenticate...

You mean the identifier is the user ID or the video ID... If we get a list of videos, aren't the IDs of the videos contained in the response? Can't we just use them to init the XCDYouTube?

Identifier is the identifier of the caption.

Here is how I retrieve the captions list, select the English one an try to download it:

func fetchCaptions(videoId: String?, successHandler: @escaping () -> Void, errorHandler: @escaping () -> Void){

        guard let videoId = videoId else {
            return
        }

        let query = GTLQueryYouTube.queryForCaptionsList(withPart: "snippet", videoId: videoId)

        _ = youTubeService?.executeQuery(query!, completionHandler: {[weak self] (ticket, response, error) in
            if let response = response as? GTLYouTubeCaptionListResponse{

                guard let items = response.items() else {
                    logger.error("error retrieving captions - no caption items received" )
                    errorHandler()
                    return
                }

                for item in items{
                    if let caption = item as? GTLYouTubeCaption{
                        print(caption)
                        if caption.snippet.language == "en"{
                            self?.fetchCaptionWithId(captionId: caption.identifier, videoId: videoId, successHandler: {
                                successHandler()
                            }, errorHandler: {
                                errorHandler()
                            })
                        }
                    }
                }

            }else{
                logger.error(error?.localizedDescription ?? "- no youtube captions received" )
                errorHandler()
            }
        })
    }

    func fetchCaptionWithId(captionId: String, videoId: String,
                            successHandler: @escaping () -> Void, errorHandler: @escaping () -> Void){

        let query = GTLQueryYouTube.queryForCaptionsDownload(withIdentifier: captionId)
        query?.tfmt = "srt"
        query?.videoId = videoId

        _ = youTubeService?.executeQuery(query!, completionHandler: {(ticket, response, error) in

            if let response = response as? GTLYouTubeCaptionListResponse{
                print(response)
            }else{
                logger.error(error?.localizedDescription ?? "- no youtube caption received" )
                errorHandler()
            }
        })
    }
