Die folgenden Codebeispiele, in denen die Google APIs-Clientbibliothek für Ruby verwendet wird, sind für die YouTube Data API verfügbar. Du kannst diese Codebeispiele im Ordner ruby
des Code-Beispiel-Repositorys für YouTube APIs auf GitHub herunterladen.
Kanalabo hinzufügen
In diesem Beispiel wird die Methode subscriptions.insert
der API aufgerufen, um ein Abo hinzuzufügen
auf einen bestimmten Channel übertragen.

Anfrage autorisieren
Im folgenden Codebeispiel wird eine OAuth 2.0-Autorisierung durchgeführt, indem geprüft wird, ob eine lokale -Datei, die Anmeldedaten für die Autorisierung enthält. Ist die Datei nicht vorhanden, öffnet das Skript einen Browser und wartet für eine Antwort und speichert die zurückgegebenen Anmeldedaten lokal.

Meine Uploads abrufen
In diesem Beispiel wird die Methode playlistItems.list
der API aufgerufen, um eine Liste der hochgeladenen Videos abzurufen
dem Kanal zugewiesen, der mit der Anfrage verknüpft ist. Der Code ruft auch die channels.list
-Methode mit dem
Der mine
-Parameter wurde auf true
gesetzt, um die Playlist-ID abzurufen, die die
Videos hochgeladen.
