Prerequisites

This example requires that you have a running PostgreSQL database. You can start one as a Docker container using the following commands:

$ docker pull postgres
$ docker run -p 5432:5432 postgres

Running the Example

Follow the steps below to run the example:

1. Ensure you have a running PostgreSQL instance at localhost:5432.

2. Run the following command to start the example application:

    ./gradlew bootRun
   

3. Run the following command to send a request to the non-secure endpoint:

    curl -v http://localhost:8080/api/v1/nonsecure
   

   If successful, you will receive an HTTP 200 OK response.

4. Run the following command to send a request to the secure endpoint:

    curl -v http://localhost:8080/api/v1/secure
   

   You will receive an HTTP 403 Forbidden response because you have not supplied a valid API key.

5. Run the following command to send a request to the secure endpoint with an API key:

    curl -v --header "API_KEY: aec093c2c98144f99a4a365ad1d2f05e" http://localhost:8080/api/v1/secure
   

   If successful, you will now receive an HTTP 200 OK response because you have supplied a valid API key.
