我尝试检索包含所有 subscriptions 的列表,但是,在调用Await listRequest.ExecuteAsync()
时,我收到此错误消息的异常在下面的源代码中:
Google.Apis.Requests.RequestError未选择过滤器。预期之一: mySubscribers,id,mine,myRecentSubscribers,channelId [400]错误[ 消息[未选择过滤器。预期之一:mySubscribers,id,mine, myRecentSubscribers,channelId]位置[ - 参数] 原因[missingRequiredParameter]域[youtube.parameter]]
我读过这篇文章,但我根本不理解它:
官方参考:
我使用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,我也试过" id,snippet,contentDetails
"接合。
我用来进行身份验证的自动生成的 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"
]
}
}
我在上面提供的信息上做错了什么?,以及我如何解决这个问题?。
以下是相关的源代码:
请注意,如果我将属性listRequest.Mine
设置为True
,那么它不会抛出异常,但会找到零订阅。
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(原创):
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

好好得到评论。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;
会弹出并请求访问您的帐户。然后它会询问哪个YouTube帐户
运行列表时
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,您首先需要确保使用正确的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。您尚未发布您的身份验证代码,但在我的代码中,我只更改了“userName”,它将请求访问其他用户。它只是一个字符串,您可以发送您想要识别不同用户的内容。如果你没有更改字符串,那么FileDatastore已经有了一个用户,它知道这样就不会再要求访问了。我在filedatastore上的教程Google .net FileDatastore Demystified。所以改变它,它将再次请求访问:)
我还有一个YouTube样本项目,我有一段时间没有玩过,但它可能有所帮助。 Google-dotnet-samples YouTube github
