Ruby-Codebeispiele

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.
