Beispiel 2: Fehlende Links ausgeben

Get-Abfrage um fehlende oder Rotlinks auf Wikipedia:Fehlende Artikel zu erhalten. Zwei Schritte, um dies zu tun:

  • Erstelle eine GET-Abfrage an die Action API, um alle auf der angegebenen Seite eingebundenen Links zu erhalten.
  • Erhalte durch weitere Extraktion die Links, die fehlen und noch nicht in der englischsprachigen Wikipedia existieren.
Das Submodul links des Anfrage-Moduls generator=links wird als generator -Modul genutzt, um eine Reihe von Links zu erhalten, die auf einer Seite eingebunden sind.
