GoogleWebAuthorizationBroker.AuthorizeAsync挂起

我们的网站需要从后面的代码（asp.net mvc应用程序）上传video到youtube。 我正在尝试获取Google凭据，但是当我调用AuthorizeAsync时，应用程序就会挂起。 我一直在找一个解决方案，似乎没有人帮忙。 我已经搜索了谷歌和堆栈溢出的明显。 我发现的大多数提到应用程序可能无法访问appdata文件夹，因此我尝试将文件夹更改为c驱动器，d驱动器和实际的inetpub位置。 我测试过，发现我能够将应用程序写入这些位置。

更具体地说，用户是我们的管理员，客户将video上传给我们，管理员批准他们。 当管理员批准它们时，它会发布在我们的YouTube帐户上。 管理员不应该做任何事情，只需单击批准按钮。

为了使这成为一个实际问题，我该怎样做才能通过AuthorizeAsync？ 如果您需要更多信息，请告诉我

UserCredential credential; GoogleWebAuthorizationBroker.Folder = "YouTube.Auth.Store"; using (var stream = new FileStream(CredentialsPath, FileMode.Open, FileAccess.Read)) { credential = GoogleWebAuthorizationBroker.AuthorizeAsync( GoogleClientSecrets.Load(stream).Secrets, // This OAuth 2.0 access scope allows an application to upload files to the // authenticated user's YouTube channel, but doesn't allow other types of access. new[] { YouTubeService.Scope.YoutubeUpload }, "user", CancellationToken.None, new FileDataStore("YouTube.Auth.Store") ).Result; } 

Answer 1

找到了通过这个的方法。

我改用了GoogleAuthorizationCodeFlow。 结果如下：

  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" }); 

Answer 2

如果这样，例如使用超时，则可能会中断，因为AuthorizeAsync方法具有CancellationToken的实现。

• 创建TokenSource以获取令牌本身。
• 将TokenSource的取消设置为20秒
• 提取令牌以传递给AuthorizeAsync方法。

---

 public async void RunAsync() { UserCredential credential; var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read); CancellationTokenSource cts = new CancellationTokenSource(); cts.CancelAfter(TimeSpan.FromSeconds(20)); CancellationToken ct = cts.Token; credential = await GoogleWebAuthorizationBroker.AuthorizeAsync( GoogleClientSecrets.Load(stream).Secrets, new[] { YouTubeService.Scope.YoutubeUpload }, "user", ct ); if (ct.IsCancellationRequested) return; // do more stuff when came back authorized. } 

现在，20秒后，当AuthorizeAsync 未完成时，此方法RunAsync的调用者将收到exception。

 try { await RunAsync(); } catch(Exception) { // "Timeout" of the RunAsync(); }

以下代码允许您使用google驱动器api凭据从用户请求登录信息，并将文件下载到您的服务器以执行某些请求：
