Bestätigen Sie automatisch bekannte Amazon Cognito Cognito-Benutzer mit einer Lambda-Funktion mithilfe eines AWS SDK
Das folgende Codebeispiel zeigt, wie bekannte Amazon Cognito Cognito-Benutzer automatisch mit einer Lambda-Funktion bestätigt werden.
Konfigurieren Sie einen Benutzerpool, um eine Lambda-Funktion für den
PreSignUp
Trigger aufzurufen.Melden Sie einen Benutzer bei Amazon Cognito an.
Die Lambda-Funktion scannt eine DynamoDB-Tabelle und bestätigt automatisch bekannte Benutzer.
Melden Sie sich als neuer Benutzer an und bereinigen Sie anschließend die Ressourcen.
