Es gibt drei Methoden, Entitäten mit der Google Ads API abzurufen und Berichtsdaten abzurufen:
GoogleAdsService.SearchStreamGoogleAdsService.Search- GET-Anfragen
In diesem Leitfaden geht es hauptsächlich um das Streamen von Daten aus GoogleAdsService. Im Folgenden finden Sie eine Übersicht über die drei Methoden zum Datenabruf:
| GoogleAdsService.Suchstream | GoogleAdsService | GET-Anfragen | |
|---|---|---|---|
| Geeignet für Produktionscode | Yes | Yes | Nein (nur für Debugging) |
| Dienst | GoogleAdsService |
GoogleAdsService |
Ressourcenspezifische Dienste (z. B. CampaignService) |
| Szenario | Objekte und Berichte abrufen | Objekte und Berichte abrufen | Objekte werden abgerufen |
| Antwort | Stream von GoogleAdsRow-Objekten |
Seiten mit GoogleAdsRow-Objekten |
Ein Objekt, z. B. Campaign |
| Antwortfelder | Nur in der Abfrage angegebene Werte | Nur in der Abfrage angegebene Werte | Alle Felder ausgefüllt |
| Tageslimits | Tageslimits anhand von Zugriffsebenen | Tageslimits anhand von Zugriffsebenen | 1.000 Anfragen pro Tag |
Suchstream vs. Suche
Während Search mehrere paginierte Anfragen zum Herunterladen des gesamten Berichts senden kann, sendet SearchStream eine einzelne Anfrage und initiiert eine dauerhafte Verbindung mit der Google Ads API, unabhängig von der Größe des Berichts.
Bei SearchStream werden Datenpakete sofort heruntergeladen, wobei das gesamte Ergebnis in einem Datenzwischenspeicher im Cache gespeichert wird. Ihr Code kann beginnen, die zwischengespeicherten Daten zu lesen, ohne auf den Abschluss des gesamten Streams warten zu müssen.
Da die Zeitspanne, die erforderlich ist, um jede einzelne Seite einer Search-Antwort anzufordern (je nach Anwendung), kann SearchStream eine bessere Leistung als Paging bieten, insbesondere bei größeren Berichten.
Beispiel
Angenommen, ein Bericht besteht aus 100,000 Zeilen. In der folgenden Tabelle sind die Abrechnungsunterschiede zwischen den beiden Methoden aufgeführt.
| Suchstream | Suchen | |
|---|---|---|
| Seitengröße | Nicht zutreffend | 10.000 Zeilen pro Seite |
| Anzahl der API-Anfragen | 1 Anfrage | 10 Anfragen |
| Anzahl der API-Antworten | 1 kontinuierlicher Stream | 10 Antworten |
Leistungsfaktoren
Im Allgemeinen empfehlen wir SearchStream über Search, und zwar aus den folgenden Gründen.
Berichte für einzelne Seiten (unter 10.000 Zeilen): Es gibt keine signifikanten Leistungsunterschiede zwischen den beiden Methoden.
Bei Berichten zu mehreren Seiten ist
SearchStreamin der Regel schneller, da mehrere Roundtrips vermieden werden müssen und das Lesen/Schreiben aus dem Festplatten-Cache weniger Faktor ist.
Ratenbegrenzungen
Die Tageslimits für beide Methoden entsprechen den Standardlimits und Zugriffsebenen Ihres Entwicklertokens. Eine einzelne Abfrage oder ein einzelner Bericht wird als ein Vorgang gezählt, unabhängig davon, ob das Ergebnis auf einer Seite angezeigt oder gestreamt wird.
