Use Gradle:

./gradlew bootRun

Run functional tests:

./gradlew integrationTest

Test the profile endpoint:

curl http://localhost:8080/profile

You should receive the following JSON response, which indicates you are not authorized to access the resource:

{
  "error": "unauthorized",
  "error_description": "Full authentication is required to access this resource"
}

In order to access the protected resource, you must first request an access token via the OAuth handshake. The API supports both password and client_credentials OAuth grant types. The password grant type should be used for API calls that require a particular user. The client_credentials grant type should be used for API calls when there is no user (i.e. registration). The entire API is secured by OAuth with the exception of the token endpoint /oauth/token which is secured by basic authentication.

Request an OAuth authorization with client_credentials grant type using the client_id and client_secret for basic authentication:

curl -X POST -u demo-client:123456 http://localhost:8080/oauth/token\?grant_type=client_credentials -H "Accept: application/json"

A successful client_credentials authorization results in the following JSON response:

{
  "access_token": "cf96e458-12a1-4854-908d-419a35118363",
  "token_type": "bearer",
  "expires_in": 43199,
  "scope": "read write"
}

Then use the access_token to call the /register endpoint to create a new user account:

curl http://localhost:8080/register -H "Authorization: Bearer cf96e458-12a1-4854-908d-419a35118363" -H "Content-Type: application/json" -X POST -d '{"username":"bobbywarner", "password":"xyz", "email":"[email protected]", "fullName": "Bobby Warner"}'

A successful registration results in the following JSON response (the password is not returned):

{
  "fullName": "Bobby Warner",
  "email": "[email protected]",
  "username": "bobbywarner"
}

Request an OAuth authorization with password grant type using the client_id and client_secret for basic authentication as well as the username and password for the specific user:

curl -X POST -u demo-client:123456 http://localhost:8080/oauth/token -H "Accept: application/json" -d "password=xyz&username=bobbywarner&grant_type=password&scope=read%20write"

A successful password authorization results in the following JSON response. This is very similar to the client_credentials authorization except it also includes a refresh_token.

{
  "access_token": "ff16372e-38a7-4e29-88c2-1fb92897f558",
  "token_type": "bearer",
  "refresh_token": "f554d386-0b0a-461b-bdb2-292831cecd57",
  "expires_in": 43199,
  "scope": "read write"
}

Then use the access_token returned in the previous request to make authorized requests to any additional protected endpoints:

curl http://localhost:8080/profile -H "Authorization: Bearer ff16372e-38a7-4e29-88c2-1fb92897f558"

After the specified time period, the access_token will expire. Use the refresh_token that was returned in the password OAuth authorization to retrieve a new access_token:

curl -X POST -u demo-client:123456 http://localhost:8080/oauth/token -H "Accept: application/json" -d "grant_type=refresh_token&refresh_token=f554d386-0b0a-461b-bdb2-292831cecd57"
