Hi.
I'm trying to write JS code in my browser that will run a prototype Wikidata bot
(written in Browser-side JS) that will use XMLHttpRequest() to login to WikiData via a Bot
Password for the purposes of making an edit. I'm running into CORS issues.
If I disable CORS in my browser, I can POST with:
?action=login&format=json&lgname=BOTNAME&lgpassword=BOTPASSWORD' and I
successfully get a login token.
However, if I don't disable CORS, my browser errors with:
'XMLHttpRequest cannot load
https://www.wikidata.org/w/api.php. Origin
http://localhost:8080 is not allowed by Access-Control-Allow-Origin’
Note that the same request that fails in the browser works fine with ‘curl’.
I’ve tried adding ‘origin=*’. I’ve toggled withCredentials, and I’ve tried a variety of
combinations of these.
I’m wondering if it is even possible to have a webpage that can obtain login access (via
bot user/pw), and make WikiData edits. I know that the rest of the Wiki sites can uses
CORS between each other, because they are whitelisted. My site is not on the whitelist,
and it shouldn’t be.
An even simpler request that fails is this:
https://www.wikidata.org/w/api.php?action=query&format=json&meta=to…
It works when I disable CORS in the browser, but fails with the same error as above
(remember, this is XMLHttpRequest, not just typing into the URL field).
I want to avoid writing server code just to defeat the browser’s CORS protection.
Thanks for any help you can provide,
Dan
