Uploads abrufen
Im folgenden Codebeispiel wird die Methode playlistItems.list der API aufgerufen, um eine Liste der Videos abzurufen, die auf den mit der Anfrage verknüpften Kanal hochgeladen wurden. Der Code ruft auch die Methode channels.list auf, wobei der Parameter mine auf true gesetzt ist, um die Playlist-ID abzurufen, mit der die hochgeladenen Videos des Kanals identifiziert werden.
