YouTube API v3 在尝试列出我的订阅时抛出 "No filter selected" 错误

YouTube API v3 throws "No filter selected" error trying to list my subscriptions

我正在尝试检索包含我所有 subscriptions 的列表,但是,我在调用 [=15= 时收到此错误消息的异常] 在下面的源代码中:

Google.Apis.Requests.RequestError No filter selected. Expected one of: mySubscribers, id, mine, myRecentSubscribers, channelId [400] Errors [ Message[No filter selected. Expected one of: mySubscribers, id, mine, myRecentSubscribers, channelId] Location[ - parameter] Reason[missingRequiredParameter] Domain[youtube.parameter] ]

我读了这个,但我完全不明白:

以及官方参考:


我正在使用 YouTubeService.Scope.Youtube 范围 (https://www.googleapis.com/auth/youtube)

我正在使用“snippet”列表选择器尝试列出我的订阅,我也尝试使用“id,snippet,contentDetails”加入。

我用来验证的自动生成的 client_secrets.json 文件包含以下内容:

{
   "installed":{
      "client_id":"xxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com",
      "project_id":"xxxxxxxxxxxxxxxxxxx",
      "auth_uri":"https://accounts.google.com/o/oauth2/auth",
      "token_uri":"https://accounts.google.com/o/oauth2/token",
      "auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs",
      "client_secret":"xxxxxxxxxxxxxxxxx",
      "redirect_uris":[
         "urn:ietf:wg:oauth:2.0:oob",
         "http://localhost"
      ]
   }
}

我上面提供的信息有问题吗?,以及我该如何解决这个问题?

这里是相关的源代码:

请注意,如果我将 属性 listRequest.Mine 设置为 True,则它不会抛出异常,但会发现零订阅。

C#(在线翻译):

public Task<List<Subscription>> GetSubscriptions(SubscriptionsResource.ListRequest.OrderEnum resultSorting)
{

   if (!(this.isAuthorizedB)) {
      throw new InvalidOperationException(this.authExceptionMessage);

   } else {
      SubscriptionsResource.ListRequest listRequest = Await this.client.Subscriptions.List("snippet");
      // listRequest.MySubscribers = False
      // listRequest.Mine = False
      listRequest.MaxResults = 50;
      listRequest.Order = resultSorting;

      SubscriptionListResponse searchResponse = Await listRequest.ExecuteAsync();

      List<Subscription> subscriptions = new List<Subscription>();

      while (true) {
         foreach (Subscription searchResult in searchResponse.Items) {
            subscriptions.Add(searchResult);
         }

         if (!string.IsNullOrEmpty(searchResponse.NextPageToken)) {
            listRequest.PageToken = searchResponse.NextPageToken;
            searchResponse = listRequest.ExecuteAsync();
         } else {
            break; // TODO: might not be correct. Was : Exit Do
         }

      }

      return subscriptions;

   }

}

VB.NET(原件):

Public Async Function GetSubscriptions(ByVal resultSorting As SubscriptionsResource.ListRequest.OrderEnum) As Task(Of List(Of Subscription))

    If Not (Me.isAuthorizedB) Then
        Throw New InvalidOperationException(Me.authExceptionMessage)

    Else
        Dim listRequest As SubscriptionsResource.ListRequest = Me.client.Subscriptions.List("snippet")
        With listRequest
            ' .MySubscribers = False
            ' .Mine = False
            .MaxResults = 50
            .Order = resultSorting
        End With

        Dim searchResponse As SubscriptionListResponse = Await listRequest.ExecuteAsync()

        Dim subscriptions As New List(Of Subscription)
        Do While True

            For Each searchResult As Subscription In searchResponse.Items
                subscriptions.Add(searchResult)
            Next searchResult

            If Not String.IsNullOrEmpty(searchResponse.NextPageToken) Then
                listRequest.PageToken = searchResponse.NextPageToken
                searchResponse = Await listRequest.ExecuteAsync()
            Else
                Exit Do
            End If

        Loop

        Return subscriptions

    End If

End Function

好吧,期待评论。注意:YouTube API 与其他 Google API 不同,它可能有点奇怪。

当您的代码 运行 是身份验证部分时

  UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets { ClientId = clientId, ClientSecret = clientSecret }
                                                                                             , scopes
                                                                                             , userName
                                                                                             , CancellationToken.None
                                                                                             , new FileDataStore("Daimto.YouTube.Auth.Store")).Result;

它将弹出并请求访问您的帐户。然后它会询问哪个 YouTube 帐户

当你运行你的列表

SubscriptionsResource.ListRequest listRequest = Await this.client.Subscriptions.List("snippet");          
      listRequest.Mine = true
      listRequest.MaxResults = 50;
      listRequest.Order = resultSorting;

      SubscriptionListResponse searchResponse = Await listRequest.ExecuteAsync();

它只会显示您选择的 YouTube 帐户的结果。因此,您需要做的第一件事是确保您使用正确的 Google 帐户和正确的 YouTube 帐户进行身份验证。您当前选择的帐户没有订阅。

您将需要对每个通过电子邮件进行身份验证的帐户进行身份验证。您还没有发布您的身份验证代码,但在我的代码中,我只是更改了 "userName",它将请求不同用户的访问权限。它只是一个字符串,您可以发送任何您想要识别不同用户的内容。如果您不更改字符串,则 FileDatastore 已经有一个用户,并且它知道这一点,因此不会再次请求访问权限。我关于文件数据存储的教程 Google .net FileDatastore Demystified。所以改变它,它会再次请求访问:)

我还有一个 YouTube 示例项目,我已经有一段时间没有玩过它了,但它可能会有所帮助。 Google-dotnet-samples YouTube github
