redirect_uri_mismatch google plus login with javascript

Question

I am trying to implement login with Google Plus in my website using JavaScript. My origin URL is http://www.locallylahore.com and my redirect URL is http://www.locallylahore.com/oauth2callback/. I tried removing www from my URLs, but it didn't work.

My website URL is http://locallylahore.com/map.php.

Answer 1

You have to make sure to add http://locallylahore.com to the "JavaScript origins" in the Google Developers Console. Since your website is reachable with and without www I would keep both variants in there. If you try to sign-in at http://www.locallylahore.com/map.php you will see that you don't get the error since you apparently already have the www-variant correctly in the Javascript origins.

Please be aware that changing the origin can take several minutes before it is active, so trying to sign-in right after changing the setting won't work.
