使用mvc应用程序将视频上​​传到youtube(后面的所有代码)

Question

这真是太疯狂了,我花了一个星期的时间试图解决这个问题.我发现的一切都被弃用或者不起作用.

所以这就是我想要做的.我们有用户上传视频,我们会将视频存储到批准之前.一旦获得批准,我们需要将其上传到我们的YouTube频道.

来自Google:https://developers.google.com/youtube/v3/code_samples/dotnet#retrieve_my_uploads的示例将无法通过GoogleWebAuthorizationBroker.AuthorizeAsync,因为它只会永久挂起.

这种方法的另一个问题是我们在上传视频后需要id,我们需要知道视频是否成功上传,所有这些都是同步的.你会看到它使用异步方法的代码,并获得视频的id,有一个回调.

有没有人知道如何同步在mvc应用程序的后端上传视频？

Answer 1

好吧,我遇到的第一个问题是身份验证挂起(从GoogleWebAuthorizationBroker.AuthorizeAsync获取凭据).解决这个问题的方法是使用GoogleAuthorizationCodeFlow,它不是异步的,并且不会尝试在appdata文件夹中保存任何内容.

我需要获得一个刷新令牌,并按照我的说法执行: 使用OAuth的Youtube API单用户场景(上传视频)

要获得可以多次使用的刷新令牌,您必须为安装的应用程序获取客户端ID和密码.

凭证是艰难的部分,之后事情就好了.有一点需要注意,因为我花了几个小时试图找出上传视频时的CategoryId.我似乎无法找到任何关于示例代码到达"22"的真实解释.我发现22是默认值,意思是"人物和博客".

继承我需要它的任何人的代码(我还需要能够删除youtube视频,所以我在这里添加了):

public class YouTubeUtilities
{
    /*

     * When getting client_id and client_secret, use installed application, other (this will make the token a long term token)
     */
    private String CLIENT_ID {get;set;}
    private String CLIENT_SECRET { get; set; }
    private String REFRESH_TOKEN { get; set; }

    private String UploadedVideoId { get; set; }

    private YouTubeService youtube;

    public YouTubeUtilities(String refresh_token, String client_secret, String client_id)
    {
        CLIENT_ID = client_id;
        CLIENT_SECRET = client_secret;
        REFRESH_TOKEN = refresh_token;

        youtube = BuildService();
    }

    private YouTubeService BuildService()
    {
        ClientSecrets secrets = new ClientSecrets()
        {
            ClientId = CLIENT_ID,
            ClientSecret = CLIENT_SECRET
        };

        var token = new TokenResponse { RefreshToken = REFRESH_TOKEN }; 
        var credentials = new UserCredential(new GoogleAuthorizationCodeFlow(
            new GoogleAuthorizationCodeFlow.Initializer 
            {
                ClientSecrets = secrets
            }), 
            "user", 
            token);

        var service = new YouTubeService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credentials,
            ApplicationName = "TestProject"
        });

        //service.HttpClient.Timeout = TimeSpan.FromSeconds(360); // Choose a timeout to your liking
        return service;
    }

    public String UploadVideo(Stream stream, String title, String desc, String[] tags, String categoryId, Boolean isPublic)
    {
        var video = new Video();
        video.Snippet = new VideoSnippet();
        video.Snippet.Title = title;
        video.Snippet.Description = desc;
        video.Snippet.Tags = tags;
        video.Snippet.CategoryId = categoryId; // See https://developers.google.com/youtube/v3/docs/videoCategories/list
        video.Status = new VideoStatus();
        video.Status.PrivacyStatus = isPublic ? "public" : "private"; // "private" or "public" or unlisted

        //var videosInsertRequest = youtube.Videos.Insert(video, "snippet,status", stream, "video/*");
        var videosInsertRequest = youtube.Videos.Insert(video, "snippet,status", stream, "video/*");
        videosInsertRequest.ProgressChanged += insertRequest_ProgressChanged;
        videosInsertRequest.ResponseReceived += insertRequest_ResponseReceived;

        videosInsertRequest.Upload();

        return UploadedVideoId;
    }

    public void DeleteVideo(String videoId)
    {
        var videoDeleteRequest = youtube.Videos.Delete(videoId);
        videoDeleteRequest.Execute();
    }

    void insertRequest_ResponseReceived(Video video)
    {
        UploadedVideoId = video.Id;
        // video.ID gives you the ID of the Youtube video.
        // you can access the video from
        // http://www.youtube.com/watch?v={video.ID}
    }

    void insertRequest_ProgressChanged(Google.Apis.Upload.IUploadProgress progress)
    {
        // You can handle several status messages here.
        switch (progress.Status)
        {
            case UploadStatus.Failed:
                UploadedVideoId = "FAILED";
                break;
            case UploadStatus.Completed:
                break;
            default:
                break;
        }
    }
}

我没有尝试过,但据我所知,ApplicatioName可以是你想要的任何东西.我只是测试,这是我在youtube中为客户端ID和秘密提供的项目名称,但我认为你可以放任何东西？
