CORS support for access to openrefine-wikidata about openrefine-wikibase HOT 11 CLOSED

@mvolz thanks for the pointers. I will try to get this solved today.

Same issue :). Basically any browser-side script (i.e. gadgets) on Wikidata/Wikipedia won't be able to access the service because it's blocked.

Error is:

No 'Access-Control-Allow-Origin' header is present on the requested resource.

I briefly googled and found a gist of how to enable CORS for Bottle; maybe useful? https://gist.github.com/richard-flosi/3789163

@mvolz @jaygray0919 I have deployed the fix, let me know if there are still issues on your side.

I do get this error, but it does load :).

Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback

@mvolz interesting… I don't know much about CORS so correct me if I am wrong but it seems that the problem comes from a policy from the source website (mediawiki) rather than from the behaviour of the reconciliation service itself?

from openrefine-wikibase.

Me neither, who knows! Probably a problem on my end.

we're seeing:
XHR status: 200
XHR status text: OK
XHR exposed response headers:
content-type: application/json

will test with more data later
thanks for the progress

from openrefine-wikibase.

For some reason the access header isn't there for error messages.

Not a big deal as it's not like it's supposed to give you data anyway, but inconsistent I guess.
