Hello,

I ran the sample github.php app and get the following error:

Is there something we need to configure in the github.php file in order to account for the /callback

Environment:
Ubuntu 16.04 server with LAMP stack, configured with self-signed cert.

Thanks

First off, I tried the example on my local machine, but when clicking the login link, nothing would happen. I had a feeling this was because running a PHP server locally doesn't allow for HTTPS.

So then I tried doing this on Replit and I changed the application and callback URL accordingly, e.g. $REPL_URL/callback. However, now when I click the log in link, I just keep getting this error:

GET /callback?error=redirect_uri_mismatch&error_description=The+redirect_uri+MUST+match+the+registered+callback+URL+for+this+application.&error_uri=https%3A%2F%2Fdocs.github.com%2Fapps%2Fmanaging-oauth-apps%2Ftroubleshooting-authorization-request-errors%2F%23redirect-uri-mismatch&state=db6bcd3385400582f5b74a074187c22

Not sure what to check here, any ideas?

Hi Aaron
I just started to read your book "Oauth2 simplified", but now im struggling already with the first example with GitHub. When I point my browser to localhost:8000 I get the login page as expected. Click on "Log In" redirects me to GitHub-Login. Here's my first issue: in the console, I get a warning "Cross-Origin Read Blocking (CORB) blocked cross-origin response https://api.github.com/_private/browser/stats with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details". Though, it seems to work so far. After logging in, I'm being redirected back to localhost:8000/index.php, but still get the "Not logged in" Text. When I log the access token to the console, its empty. Where's the mistake? I work on Windows 10.

I am using an NGINX web server with a regular expression to match multiple host names, and the SERVER_NAME returned is the regular expression, not the actual host name requested/used. This caused an interesting (to me) issue because Google of course did not like the regular expression as the redirect URI.

I fixed this for my site by changing this
$baseURL = 'https://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF'];
to this
$baseURL = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];

I am not sure if this is a universally wholesome change or if it introduces problems for a different configuration. Just sharing in case it is helpful to someone else.

Thanks
