Przykładowe kody Ruby

Poniższe przykłady kodu, które korzystają z biblioteki klienta interfejsów API Google dla Ruby, są dostępne w YouTube Analytics API. Możesz pobrać te fragmenty kodu z folderu ruby w repozytorium kodu interfejsu API YouTube na GitHubie.

Autoryzowanie żądania

Poniższy przykładowy kod wykonuje autoryzację OAuth 2.0, sprawdzając, czy istnieje lokalny plik zawierający dane uwierzytelniające. Jeśli pliku nie ma, skrypt uruchamia przeglądarkę i czeka na odpowiedź, a następnie lokalnie zapisuje dane logowania.

Pobieranie 10 najpopularniejszych filmów według liczby wyświetleń

W tym przykładzie wywołujemy metodę reports.query interfejsu API, która pozwala pobrać dane ze Statystyk YouTube. Domyślnie raport pobiera 10 najpopularniejszych filmów na podstawie liczby wyświetleń, a następnie zwraca dla nich kilka danych, sortując wyniki w odwrotnej kolejności od liczby wyświetleń. Po ustawieniu parametrów wiersza poleceń możesz używać tego samego kodu do pobierania innych raportów.
