# Protospace lockout authorization server

Provides an API to the web client and web server to serve tool data and authenticate users on tools.

## Setup

```
$ sudo apt install python3 python3-pip python3-virtualenv   # for Debian
$ virtualenv -p python3 env
$ . env/bin/activate
(env) $ pip install -r requirements.txt
(env) $ python manage.py migrate --run-syncdb
(env) $ python manage.py createsuperuser --email admin@example.com --username admin
(env) $ python manage.py runserver
```

Authenticate a Protospace login using the `curl` command below against **your** server, then navigate to http://127.0.0.1:8000/admin/ and login with the superuser account you just created above.

Once logged in, navigate to "Profiles" and make your Protospace user a lockout admin.

Now you have total control of the system and can make other users lockout admins though the API or web interface.

## API

The API is RESTful and returns hyperlinked json data. **URLs require a trailing slash.**

It's also possible to interact with the API through a web interface at http://tools-auth.protospace.ca from the Protospace LAN. Any Protospace users that have already authenticated through /login/ are able to login.

### Authentication

Authentication is token-based and done against the Protospace member portal. Upon successful login, the auth server will automatically register the user and create them a profile.

#### POST `/login/`

POST data `username` and `password`. Upon successful login, a 200 status and a token will be returned.

Example request:

```
curl -d username=tanner.collin -d password=supersecret http://tools-auth.protospace.ca/login/
```

Example response:

```
{
    "token": "9944b09199c62bcf9418ad846dd0e4bbdfc6ee4b"
}
```

In subsequent requests, the token key should be included in the `Authorization` HTTP header. The key should be prefixed by the string literal "Token", with whitespace separating the two strings. For example:

```
Authorization: Token 9944b09199c62bcf9418ad846dd0e4bbdfc6ee4b
```

Example authenticated request:

```
curl -H "Authorization: Token 9944b09199c62bcf9418ad846dd0e4bbdfc6ee4b" http://tools-auth.protospace.ca/user/
```
