Ruby-Codebeispiele

Die folgenden Codebeispiele, die die Google APIs-Clientbibliothek für Ruby verwenden, sind für YouTube Analytics API verfügbar. Sie können diese Codebeispiele aus dem Ordner ruby des Beispiel-Repositorys für YouTube APIs auf GitHub herunterladen.

Anfrage autorisieren

Mit dem folgenden Codebeispiel wird die OAuth 2.0-Autorisierung durchgeführt. Dabei wird geprüft, ob eine lokale Datei mit Autorisierungsanmeldedaten vorhanden ist. Ist die Datei nicht vorhanden, öffnet das Skript einen Browser, wartet auf eine Antwort und speichert die zurückgegebenen Anmeldedaten lokal.

Top-10-Videos nach Anzahl der Aufrufe abrufen

In diesem Beispiel wird die Methode reports.query der API aufgerufen, um YouTube Analytics-Daten abzurufen. Standardmäßig ruft der Bericht die Top-10-Videos anhand der Anzahl der Aufrufe ab. Dabei werden mehrere Messwerte für diese Videos zurückgegeben. Die Ergebnisse werden in umgekehrter Reihenfolge nach der Anzahl der Aufrufe sortiert. Wenn Sie Befehlszeilenparameter festlegen, können Sie denselben Code verwenden, um auch andere Berichte abzurufen.
