Следующие примеры кода, использующие клиентскую библиотеку API Google для Ruby , доступны для YouTube Analytics API . Вы можете скачать эти примеры кода из папки ruby репозитория примеров кода API YouTube на GitHub .
Авторизовать запрос
Следующий пример кода выполняет авторизацию OAuth 2.0, проверяя наличие локального файла, содержащего учетные данные авторизации. Если файл отсутствует, сценарий открывает браузер и ожидает ответа, а затем сохраняет возвращенные учетные данные локально.

Получить 10 лучших видео по количеству просмотров
В этом примере вызывается метод reports.query API для получения данных YouTube Analytics. По умолчанию отчет извлекает 10 лучших видео на основе количества просмотров и возвращает несколько показателей для этих видео, сортируя результаты в обратном порядке по количеству просмотров. Установив параметры командной строки, вы можете использовать тот же код и для получения других отчетов.
