API

Diskussion

Dies ist ein auf der MediaWiki API basierendes Framework mit Funktionen für Bots. Als Grundlage diente das alte Skript vom PmegBot, welches ich im prinzip übernommen und die WP-Zugriffe auf API-Funktionen umgestellt habe.

Damit das Framework funktioniert wird noch der Code von PHPPOSTRequest benötigt, der als PostRequest.php in mein Framework includiert wird und eine Funktion für den zum Zugriff auf die Wikipedia nötigen POST-Request bereitstellt.

Das Framework ist noch nicht komplett. Es fehlen noch die restlichen API-Schnittstellen und eine Internationalisierung, bis jetzt greift das Skript nur auf http://de.wikipedia.org/w/api.php zu.
