An experimental gRPC authentication service using Spring Boot and GCP Identity Platform.
To start the application:
./gradlew clean bootRun
A JWT token is sent through to the service as an "Authorization: Bearer token" metadata pair. The service decodes the token and responds with success true/false, along with a status code and message.
To test you can set up simple email/password auth in Identity Platform, then run the below curl command to get a token. Also remember to set the PROJECT_ID (in the application.yml file) env variable to your GCP project ID.
curl -X POST "https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=<your-api-key>" \
-H "Content-Type: application/json" \
-d '{
"email": "<your-email>",
"password": "<your-password>",
"returnSecureToken": true
}'
Once the above is completed and you have a token, run:
grpcurl -plaintext \
-emit-defaults \
-d '{}' \
-H "Authorization: Bearer <jwt-token>" \
localhost:9090 AuthService/Authenticate
To run auth service tests:
./gradlew clean check
