Warden Strategy for DMA Online JWT Authentication. Checks for a JWT (JSON Web Token) in either the Authorization header as a Bearer token or the get parameters of the request.
On successful authentication it returns an instance of DMAO::WardenJWT::User which has attributes and methods for checking the users institution as well as authenticated roles.
Add this line to your application's Gemfile:
gem 'DMAO-WardenJWT'And then execute:
$ bundle
Or install it yourself as:
$ gem install Bundle-WardenJWT
DMAO-WardenJWT requires the following environment variables to be set, this can be done using the dotenv gem.
| Environment Variable | Description |
|---|---|
| JWT_VERIFY_ISS | Boolean for whether to verify the token issuer (false allows for jwt_issuer to be nil) |
| JWT_VERIFY_AUD | Boolean for whether to verify the token audience (false allows for jwt_audience to be nil) |
| JWT_VERIFY_IAT | Boolean for whether to verify the issued at timestamp of the token |
| JWT_SECRET | The secret used to verify the integrity of the JWT (required) |
| JWT_ISSUER | The issuer of the JWT (required) |
| JWT_AUDIENCE | The audience for the JWT (required) |
| JWT_CUSTOM_CLAIMS_ATTRIBUTE | The name of the claim within the JWT to extract as the DMA Online custom claims (dmao is a sensible default) |
DMAO-WardenJWT does not define a failure app. Handling authentication failure should be handled within the service/application using this.
After including the gem add the following to config/application.rb. This is correct for using with Rails 5 when in API mode.
config.middleware.insert_after Rack::ETag, Warden::Manager do |manager|
manager.default_strategies :jwt
