[Interest] Qt Network Authorization example redirect URI

[Tom Isaacson]

I've installed Qt 5.10.1 and I'm trying to get the Reddit example for Qt Network Authorization to work:
https://doc.qt.io/archives/qt-5.10/qtnetworkauth-redditclient-example.html

The instructions tell you to go to https://www.reddit.com/prefs/apps and get a consumer key. I created an app called QtNetworkAuthProject and set the redirect URI to http://localhost:8080/cb as suggested here:
http://blog.qt.io/blog/2017/01/25/connecting-qt-application-google-services-using-oauth-2-0/

But when I run the app Reddit says "invalid redirect_uri parameter". Apparently this can also be because the redirect URI is wrong:

This answer suggests the blog post is out of date and it should be http://localhost:8080/ but that fails as well:

Does anyone know what the correct setting is? Also, someone should really update the example to explain this better!

Thanks.
