yup-oauth2 is a utility library which implements several OAuth 2.0 flows. It's mainly used by google-apis-rs, to authenticate against Google services. (However, you're able to use it with raw HTTP requests as well; the flows are implemented as token sources yielding HTTP Bearer tokens).

Supported authorization types

• Device flow (user enters code on authorization page)
• Installed application flow (user visits URL, copies code to application, application uses code to obtain token). Used for services like GMail, Drive, ...
• Service account flow: Non-interactive for server-to-server communication based on public key cryptography. Used for services like Cloud Pubsub, Cloud Storage, ...

Usage

Please have a look at the [API landing page][API-docs] for all the examples you will ever need.

A simple commandline program which authenticates any scope and prints token information can be found in [the examples directory][examples].

The video below shows the auth example in action. It's meant to be used as utility to record all server communication and improve protocol compliance.
