BadServerResponse didn't seem to be adequately different from NegativeServerResponse so it's been removed. NegativeServerResponse is now a struct variant with field names 'error' and 'error_description' to self document what it contains. InvalidClient and InvalidScope were only ever created based on string parsing of the returned error message from the server. This seemed overly specific to a particular implementation and didn't provide much value to callers. Printing a NegativeServerResponse would provide users the same information. The caching layer never returns errors anymore so remove that variant.
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).
The provider we have been testing the code against is also Google. However, the code itself is generic, and any OAuth provider behaving like Google will work as well. If you find one that doesn't, please let us know and/or contribute a fix!
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 authorization of 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 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.
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.
