auth-api

This part of the exercise is responsible for authentication. It is written in Go and tested with Go1.9.

It provides a single useful API endpoint POST /login that takes a simple JSON object and returns an access token in case of successful authentication.

The JSON object structure is following:

{
    "username": "admin",
    "password": "admin",
}

Prerequisites

Users API must be running, because auth-api fetches user data from it (yes, it is a little bit contrived, but anyways it's OVERENGINEERING!)

Configuration

The service scans environment for variables:

• AUTH_API_PORT - the port the service takes.
• USERS_API_ADDRESS - base URL of Users API.
• JWT_SECRET - secret value for JWT generator. Must be shared amongst all components.

Following users are hardcoded for you:

Username	Password
admin	admin
johnd	foo
janed	ddd

Building and running

1. Update the dependencies with glide

glide up

1. Compile a binary and then run it

go build
AUTH_API_PORT=8000 USERS_API_ADDRESS=http://users-api:8082 JWT_SECRET=foo ./auth-api

Usage

 curl -X POST  127.0.0.1:8000/login -d '{"username": "admin","password": "admin"}'
