TASK DESCRIPTION
I am trying to make an OAuth2-authenticated request on Wikidata from an SPA
on a localhost web client. However, I keep on running into CORS errors, and I
double-checked the origin to make sure I am doing it right. I copied the
request into cURL and found something interesting:
* Trying 2620:0:861:ed1a::1:443...
* Connected to www.wikidata.org (2620:0:861:ed1a::1) port 443 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1
* successfully set certificate verify locations:
* CAfile: /etc/ssl/cert.pem
* CApath: none
* (304) (OUT), TLS handshake, Client hello (1):
* (304) (IN), TLS handshake, Server hello (2):
* (304) (IN), TLS handshake, Unknown (8):
* (304) (IN), TLS handshake, Certificate (11):
* (304) (IN), TLS handshake, CERT verify (15):
* (304) (IN), TLS handshake, Finished (20):
* (304) (OUT), TLS handshake, Finished (20):
* SSL connection using TLSv1.3 / AEAD-CHACHA20-POLY1305-SHA256
* ALPN, server accepted to use h2
* Server certificate:
* subject: CN=*.wikipedia.org
* start date: Oct 26 08:25:13 2022 GMT
* expire date: Jan 24 08:25:12 2023 GMT
* subjectAltName: host "www.wikidata.org" matched cert's "*.wikidata.org"
* issuer: C=US; O=Let's Encrypt; CN=R3
* SSL certificate verify ok.
* Using HTTP2, server supports multiplexing
* Connection state changed (HTTP/2 confirmed)
* Copying HTTP/2 data in stream buffer to connection buffer after upgrade:
len=0
* Using Stream ID: 1 (easy handle 0x156011400)

I am getting valid data but a complete lack of any CORS headers, so my
browser is unable to do the request.
