Slim Bookshelf API

A simple Slim Framework API with OAuth 2 authentication.

There are two different apps:

api - This is the API itself with various endpoints.
web - This is a first party website that allows a user to authenticate third party apps.

Running the apps:

Run the migrations:
```
 $ composer migrate
```

Load the api/db/fixtures/default.sql into your database:

 $ cat api/db/fixtures/default.sql | sqlite3 api/db/bookshelf.db

Run the API:
```
 $ php -S 0.0.0.0:8888 -t public/
```
Run the Website:
```
 $ php -S 0.0.0.0:8889 -t public/
```

Authentication via OAuth 2

The api protects it data and requires an OAuth2 Bearer token to access the data enpoints (authors).

It supports both Password grant for 1st party apps (user enters their username and password) and the Authorisation Code grant (user authorises the 3rd party app on our web site and the app then get a token it can use).

Logging in

The relevant credentials are:

1st party client: client_id: mywebsite client_secret: abcdef 3rd party client: client_id: testclient client_secret: abcdef Test user: username: rob password: 123456

Password grant

To log in with the user's credentials directly, we use the password grant type against the /token endpoint. We need to specify the client's credentials along with the user's:

$ curl -X POST http://localhost:8888/token \
    -H "Accept: application/json" \
    -H "Content-Type: application/json" \
    -d $'{
        "grant_type": "password",
        "client_id": "mywebsite",
        "client_secret": "abcdef",
        "username": "rob",
        "password": "123456"
    }'

If it succeeds, you will get a response containing JSON like this:

{
  "access_token": "5be4bdb0f09c9405f4beadd4d087cd8c5d66aa36",
  "expires_in": 3600,
  "token_type": "Bearer",
  "scope": null,
  "refresh_token": "8b3c07ee9c0c48078ce8a29e413c6497d399dd8e"
}

You can then access the API by including the access_token in the Authorization header:

$ curl http://localhost:8888/authors \
 -H "Authorization: Bearer 5be4bdb0f09c9405f4beadd4d087cd8c5d66aa36" \
 -H "Accept: application/json"

Authorisation Code grant

Go the website with this URL:

http://localhost:8889/authorise?response_type=code&client_id=testclient&redirect_uri=http%3A%2F%2Ffake&state=1234

You will be redirected to the login page, log in using the Test user's credentials which will take you back to the Authorise 3rd Party Application page.

Click "Yes" and the authorisation code will be displayed. The code looks something like this: 64eae4125c8ce6589daf06d0c20a7aa97a5aff55.

You can now get a token from the API's /token endpoint:

$ curl -X "POST" http://localhost:8888/token \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \
  -d $'{
   "grant_type": "authorization_code",
   "client_id": "testclient",
   "client_secret": "abcdef",
   "code": "64eae4125c8ce6589daf06d0c20a7aa97a5aff55",
   "redirect_uri": "http://fake"
  }'
