Entdecken von abgelehnten Anzeigen

Diese Lösung zeigt, wie Sie nicht genehmigte Anzeigen für ein oder mehrere Konten ermitteln. Im Folgenden finden Sie den allgemeinen Ablauf des Skripts. Weitere Informationen finden Sie in den Inlinekommentaren.

• Liest eine Datei aus Google Drive. Die Datei enthält eine Liste von -Objekten. Jedes Objekt enthält eine Konto-ID und einen Zeitstempel, der angibt, wann das Konto zuletzt auf abgelehnte Anzeigen überprüft wurde. Bei der ersten Ausführung des Skripts sollte die Datei nicht vorhanden sein. Wenn die Datei nicht vorhanden ist, erstellt das Skript die vollständige Liste der Konten, auf die Sie Zugriff haben. Beachten Sie, dass das Skript keine neuen Konten übernimmt, die Sie hinzufügen, nachdem die Datei erstellt wurde. Wenn Sie Konten hinzufügen, sollten Sie die Datei löschen, damit eine neue Liste von Konten generiert wird.
• Sortiert die Kontoliste so, dass die Konten, die nicht überprüft wurden oder die ältesten sind, zuerst angezeigt werden.
• Ruft bis zu den ersten 50 Konto-IDs aus der Liste ab und ruft die executeInParallel-Methode des Selektors auf. Die -Methode führt parallel die findDisapprovedAds-Funktion für jedes Konto aus. Diese Funktion gibt ein Objekt zurück, das die Informationen des Kontos und ggf. die Liste der abgelehnten Anzeigen enthält.
• Führt die reportResults-Funktion aus, nachdem alle findDisapprovedAds-Funktionsaufrufe abgeschlossen sind. Diese Funktion erstellt ein Arbeitsblatt und verwendet Google Sheets, um ein Blatt für jedes Konto zu erstellen. Wenn das Konto abgelehnte Anzeigen enthält, schreibt es die Anzeigen auf das Blatt.
• Verwendet Google Mail, um eine E-Mail-Benachrichtigung an die angegebenen Empfänger zu senden. Die E-Mail gibt an, ob ein Konto abgelehnte Werbung enthält, und stellt einen Link zu dem Blatt bereit, auf dem die Details angezeigt werden können.
• Updates das Feld lastChecked für jedes Konto aus, und speichert die Datei. Bei der nächsten Ausführung des Skripts wird die Liste der Konten nach dem LastChecked-Zeitstempel sortiert. Dies bedeutet, dass alle Konten, die nicht verarbeitet wurden oder die ältesten sind, an erster Stelle in der Liste stehen. Dieses Skript muss je nach Anzahl von Konten ein oder mehrere Male ausgeführt werden.
