Issue
Wikimedia Commons Query Service's end point rejects external queries :
- Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://commons.wikimedia.org/wiki/Special:OAuth/authenticate?oauth_token=b0685605ac44eb315c2571d1a0fb43db. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 302.
According to commons:Commons:SPARQL_query_service#Release_notes :
- OAuth is currently not working. See https://stackoverflow.com/questions/65303450/how-to-authenticate-to-wikimedia-commons-query-service-using-oauth-in-python#comment115828158_65424900. This is so that we can contact abusive bots and/or users and block them selectively as a last resort if needed.
