Teilweise fehlgeschlagene Vorgänge

In der Google Ads API können Sie festlegen, dass gültige Vorgänge ausgeführt werden und Fehler auftreten. bei denen Fehler zurückgegeben werden. Mit dieser Funktion, die auch als partielle Fehler bezeichnet wird, können Sie Fehlgeschlagene Vorgänge am Ende separat verarbeiten. Es ist verfügbar in Non-get-Methoden vieler Google Ads API-Dienste.

Technische Details

Um diese Funktion zu nutzen, müssen Sie den partialFailure-Parameter des die Sie verwenden möchten. Dies kann je nach Kunde unterschiedlich sein. Bibliothek. Gehen Sie beispielsweise wie folgt vor, um diese Funktion zu aktivieren, wenn Sie eine Anfrage mit MutateAdGroups:

Java

mutateAdGroups(String.valueOf(customerId), operations, true)

C#

MutateAdGroups(customerId.ToString(), operations, true, false)

PHP

mutateAdGroups($customerId, $operations, ['partialFailure' => true])

Python

mutate_ad_groups(customer_id, operations, partial_failure=True)

Ruby

mutate_ad_groups(customer_id, operations, partial_failure: true)

Perl

mutate({customerId => $customer_id, operations => $operations, partialFailure => 'true'})

Der Dienst führt nun die Vorgänge aus, die fehlerfrei sind. Es wird eine Ergebnisse für erfolgreiche Vorgänge und Fehler für fehlgeschlagene Vorgänge.

Nutzung

Angenommen, Sie möchten Ihrem Konto mehrere Anzeigengruppen hinzufügen. Einige der Anzeigengruppen können Probleme aufweisen. Sie möchten die gültigen Anzeigengruppen, aber die fehlgeschlagenen Anzeigengruppen werden zusammen mit den entsprechenden Fehlern zurückgegeben.

Vorgänge erstellen und API aufrufen

Erstellen Sie die mutate-Vorgänge und rufen Sie die API wie gewohnt auf.

Erfolgreiche und fehlgeschlagene Vorgänge verarbeiten

Wenn das Ergebnis für den übermittelten Vorgang erfolgreich ist, wird die zugehörige Meldung enthält einen Ressourcennamen. In diesem Fall können Sie die Informationen einfach ausdrucken, oder für andere Zwecke verwenden.

Wenn das Ergebnis jedoch nichts enthält, bedeutet dies, dass die entsprechenden Vorgang ist fehlgeschlagen. Sie können die Fehler extrahieren. Details beginnen, indem Sie partial_failure_error der Antwort:

  • Das Feld partial_failure_error hat den Typ Status, enthält eine Liste mit Details.
  • Jedes Detail entspricht jedem übermittelten Vorgang. Es steht für eine Instanz von GoogleAdsFailure.
  • GoogleAdsFailure enthält eine Liste mit GoogleAdsError. Objekte. Daher kann ein übermittelter Vorgang viele Fehler enthalten.
  • GoogleAdsError gibt die Fehlermeldung, den Fehlercode und alle anderen relevante Details.
