For OAuth 2.0 using QT's networkauth and the new QOAuth2AuthorizationCodeFlow object, I cant set the redirect_uri. When working with google this results in the following authenticate url being sent:
The setting of redirect_uri to "http://localhost", results in an Error 400 redirect_uri_mismatch from google which is obviously expecting the actual redirect hostname to be provided.
In Qt/5.8/Src/qtnetworkauth/src/oauth/qoauthhttpserverreplyhandler.cpp, the callback address looks hard-coded. The callback() routine in turn used in Qt/5.8/Src/qtnetworkauth/src/oauth/qoauth2authorizationcodeflow.cpp to set the redirectUri value to http://localhost.
Please allow some way for the redirect uri parameter to be set.
