Ruby Kod Örnekleri

YouTube Analytics API için Ruby için Google API'leri istemci kitaplığını kullanan aşağıdaki kod örnekleri mevcuttur. Bu kod örneklerini, GitHub'daki YouTube API'leri kod örneği deposunun ruby klasöründen indirebilirsiniz.

İsteği yetkilendirme

Aşağıdaki kod örneği, yetkilendirme kimlik bilgilerini içeren yerel bir dosyanın varlığını kontrol ederek OAuth 2.0 yetkilendirmesini gerçekleştirir. Dosya mevcut değilse komut dosyası bir tarayıcı açar ve yanıt bekler, ardından döndürülen kimlik bilgilerini yerel olarak kaydeder.

Görüntüleme sayısına göre en iyi 10 videoyu alma

Bu örnek, YouTube Analytics verilerini almak için API'nin reports.query yöntemini çağırır. Rapor, varsayılan olarak görüntüleme sayısına göre en iyi 10 videoyu alır ve bu videolar için çeşitli metrikler döndürür. Sonuçlar, görüntüleme sayısına göre ters sırada sıralanır. Komut satırı parametrelerini ayarlayarak diğer raporları almak için de aynı kodu kullanabilirsiniz.
