Question

我需要获得授权才能通过服务帐户使用Calendar API。

当我发出-Dim ok As Boolean = Await GetToken-指令时，我收到错误，我无法继续。请有人帮帮我吗？ TIA

这是我使用的代码：

Private Const SVCACCMAIL = "999999999999-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@developer.gserviceaccount.com"
Private Const ACTIVITY_ID = "x9x9x9x9x9x9x9x9x9x9x9x9x9x9x9x9x9x9x9"

<OperationContract()>
Public Function InsertEvent(authToken As String, id_Azienda As Integer, id_Azione As Integer, id_Op As Integer) As String
    Dim scopes As New List(Of String)
    scopes.Add("https://www.googleapis.com/auth/calendar")
    Dim inzlzr As New ServiceAccountCredential.Initializer(SVCACCMAIL) With {.User = SVCACCMAIL, .Scopes = scopes}
    Dim credential As New ServiceAccountCredential(inzlzr.FromCertificate(GetCert))

    GetAccessToken(credential)
End Function

Public Function GetCert() As X509Certificate2
    Dim fileCert As String = "D:\inetpub\wwwroot\UGO_Cont.Web\UGO-Adv-CRM-999999999999999a.p12"
    Dim cert = New X509Certificate2(fileCert, "notasecret", X509KeyStorageFlags.Exportable)
    Return cert
End Function

Async Sub GetAccessToken(cr As ServiceAccountCredential)
    Dim GetToken = cr.RequestAccessTokenAsync(System.Threading.CancellationToken.None)

    Dim ok As Boolean = Await GetToken
    Dim service As New CalendarService(New BaseClientService.Initializer() With {.ApplicationName = "Test calendar sync app", .HttpClientInitializer = cr})

    Dim list As IList(Of CalendarListEntry) = service.CalendarList.List().Execute().Items()
End Sub

观察一些工作样本，我发现ServiceAccounCtredential的初始化程序没有＆＃34;。用户＆＃34;参数。因此，删除此参数，我没有更多的身份验证错误。所以我认为身份验证错误已经消失。这些是工作线：

    Dim inzlzr As New ServiceAccountCredential.Initializer(SVCACCMAIL) With {.Scopes = scopes}

非常感谢每个看过这个问题的人。

尝试使用OAuth2会导致NOT授权客户端或范围错误
