I spent a decent amount of time trying to get OAuth working for a writing application that integrates Google Drive API. I ran into a bunch of problems with CORS and decided to do some research about what exactly CORS is. I also learned a lot about how to properly make a request to an OAuth server from a browser. If you’ve been struggling with CORS and OAuth 2.0, you might find some of this stuff helpful.
