go-http-sum

This project holds the code of simple HTTP service with two endpoints:

POST /auth: returns a response containing a JWT (OAuth 2) token with the username as a subject. The successful response follows the Oauth2 standard

POST /sum: accepts an arbitrary JSON document as payload, finds all of the numbers throughout the document and adds them together.

This API returns the appropriate error status code when an issue is found.

Querying the service

The service can be used by running

curl --request POST 'http://localhost:8000/auth' \
--data-raw '{
    "username": "user",
    "password": "pass"
}' | jq

Example output:

{
    "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6InVzZXIiLCJleHAiOjE2NDg5OTQwMTJ9.mEeg8nisxG1szUXaO9bs96ZgjzueUqYmZDWNbagiuks",
    "token_type": "Bearer",
    "expires_in": 3600
}

Once authenticated, using the JWT access token obtained, the POST sum/ endpoint can be used.

curl --request POST 'http://localhost:8000/sum' \
--header 'Authorization: Bearer <token-here>' \
--data-raw '[1,2,3,4]'
