llm-api/wiki_router.py aktualisiert

Neue Funktion zur Stabilisierung von PageID

Yes—let’s lock this down properly. I’ve put a hardened wiki_router.py (v1.4.0) in the canvas. It:

enriches /semantic/pages with pageid + fullurl for every title (batching + redirects + converttitles),

makes /info tolerant (variants) and 404-safe,

adds retry + light throttling to all MediaWiki calls,

keeps the same routes and parameters (no breaking changes),

logs coverage so we can see where things go sideways.

-File: wiki_router.py
+wiki_router.py - v1.4.0 (stabil & nachvollziehbar)
-Beschreibung:
+
-- Endpunkte für MediaWiki-Integration im lokalen Netzwerk.
+Ziele:
-- Funktionen:
+- Keine API-Signaturänderungen (bestehende Routen bleiben)
-  * /health: Prüft Verfügbarkeit der MediaWiki-API.
+- /semantic/pages reichert pageid/fullurl für ALLE Titel batchweise an (redirects=1, converttitles=1)
-  * /login: Führt clientlogin durch und speichert Session-Cookies.
+- /info robust: 404 statt 500, mit Titel-Varianten
-  * /semantic/pages: Listet alle Übungen inkl. Unterkategorien via SMW-Ask.
+- Wiederholungen & Throttling gegen MediaWiki
-  * /parsepage: Ruft Roh-Wikitext über action=parse für eine Seite ab.
+- Optionale Diagnose-Ausgaben und Coverage-Kennzahlen
-  * /info: Liefert pageid und fullurl über Core-API Query.  # CHANGED: robustes 404-Handling
+
-  * /semantic/page: Liefert Metadaten einer Übung, pageid und Wikitext.  # CHANGED: propagiert 404
+Annahme: Der Router wird in main.py mit Prefix eingebunden:
-Version: 1.3.0
+    app.include_router(wiki_router, prefix="/import/wiki")
+
+Wenn ihr stattdessen den Prefix im Router setzen wollt, einfach in der APIRouter-Zeile unten
+prefix="/import/wiki" ergänzen und in main.py OHNE prefix einbinden.
