Oauth support?

[fenchu]

If rest-api requests get 401, or web requests are forwarded to the login page, I issue an access token via our oauth2 server (keycloak) and inject it as bearer token in the header. This works fine, but it is single threaded and quite slow.

Are there ways in linkchecker to do this?

on 401 responses:

curl -i -H "Content-Type: application/x-www-form-urlencoded" -X POST "https://auth.example.com/auth/realms/<REALM>/protocol/openid-connect/token" -d "grant_type=client_credentials&client_id=<CLIENTID>&client_secret=<CLIENTSECRET>"

this will return an accesstoken in json, I can extract

{"access_token"<MYVERYLONGACCESSTOKEN>","expires_in":300,"refresh_expires_in":0,"token_type":"Bearer","not-before-policy":0,"scope":"scim_write scim_read"}

and then inject it into the requests header:

curl -X POST -H 'Accept: application/scim+json' -H 'Accept-Encoding: gzip, deflate' -H 'Authorization: Bearer <MYVERYLONGACCESSTOKEN>'
