Release notes

Motivation

To have a resource, that will do very simple thing: take the oauth code from social provider (for example facebook) and return the authenticated user. That's it.

I can't find such util for django rest framework. There are packages (for example django-rest-auth), that take access_token, not the code. Also, i've used to work with awesome library python-social-auth, so it will be nice to use it again (now it is split into social-core and social-app-django). In fact, most of the work is done by this package. Current util brings a little help to integrate django-rest-framework and python-social-auth.

Quick start

Install this package to your python distribution:
```
pip install rest-social-auth
```

Do the settings

Install apps

INSTALLED_APPS = (
    ...
    'rest_framework',
    'rest_framework.authtoken',  # only if you use token authentication
    'social_django',  # django social auth
    'rest_social_auth',  # this package
    'knox',  # Only if you use django-rest-knox
)

social auth settings, look documentation for more details

SOCIAL_AUTH_FACEBOOK_KEY = 'your app client id'
SOCIAL_AUTH_FACEBOOK_SECRET = 'your app client secret'
SOCIAL_AUTH_FACEBOOK_SCOPE = ['email', ]  # optional
SOCIAL_AUTH_FACEBOOK_PROFILE_EXTRA_PARAMS = {'locale': 'ru_RU'}  # optional


AUTHENTICATION_BACKENDS = (
    'social_core.backends.facebook.FacebookOAuth2',
    # and maybe some others ...
    'django.contrib.auth.backends.ModelBackend',
)

Also look optional settings avaliable.

Make sure everything is up do date
```
python manage.py migrate
```

Include rest social urls (choose at least one)

4.1 session authentication

path('api/login/', include('rest_social_auth.urls_session')),

4.2 token authentication

path('api/login/', include('rest_social_auth.urls_token')),

4.3 jwt authentication

path('api/login/', include('rest_social_auth.urls_jwt_pair')),

or / and

path('api/login/', include('rest_social_auth.urls_jwt_sliding')),

4.4 knox authentication

path('api/login/', include('rest_social_auth.urls_knox')),

You are ready to login users

Following examples are for OAuth 2.0.

5.1 session authentication
- POST /api/login/social/session/
  
  input:
```
  {
      "provider": "facebook",
      "code": "AQBPBBTjbdnehj51"
  }
```
  output:
```
  {
      "username": "Alex",
      "email": "user@email.com",
      // other user data
  }

  + session id in cookies
```
5.2 token authentication
- POST /api/login/social/token/
  
  input:
```
  {
      "provider": "facebook",
      "code": "AQBPBBTjbdnehj51"
  }
```
  output:
```
  {
      "token": "68ded41d89f6a28da050f882998b2ea1decebbe0"
  }
```
- POST /api/login/social/token_user/
  
  input:
```
  {
      "provider": "facebook",
      "code": "AQBPBBTjbdnehj51"
  }
```
  output:
```
  {
      "username": "Alex",
      "email": "user@email.com",
      // other user data
      "token": "68ded41d89f6a28da050f882998b2ea1decebbe0"
  }
```
5.3 jwt authentication (using django-rest-framework-simplejwt)
- POST /api/login/social/jwt-pair/
- POST /api/login/social/jwt-pair-user/
  
  Similar to token authentication, but token is JSON Web Token.
  
  See JWT.io for details.
  
  To use it, django-rest-framework-simplejwt must be installed.
  
  For jwt-pair, the response will include additional "refresh" token:
```
{
    "token": "...",
    "refresh": "..."
}
```
  Or sliding JWT token:
- POST /api/login/social/jwt-sliding/
- POST /api/login/social/jwt-sliding-user/
  
  Check docs of simplejwt for pair/sliding token difference.
  
  Note. django-rest-framework-simplejwt doesn't work on python3.6
5.4 knox authentication
- POST /api/login/social/knox/
- POST /api/login/social/knox_user/
  
  Similar to token authentication, but token is Django Rest Knox Token.
  
  To use it, django-rest-knox must be installed.
User model is taken from settings.AUTH_USER_MODEL.

At input there is also non-required field redirect_uri. If given, server will use this redirect uri in requests, instead of uri got from settings. This redirect_uri must be equal in front-end request and in back-end request. Back-end will not do any redirect in fact.

It is also possible to specify provider in URL, not in request body. Just append it to the url:
```
 POST /api/login/social/session/facebook/
```
Don't need to specify it in body now:
```
 {
     "code": "AQBPBBTjbdnehj51"
 }
```
Provider defined in URL has higher priority than provider in body. If both are specified - provider will be taken from URL.

OAuth 2.0 workflow with rest-social-auth

Front-end need to know following params for each social provider:
- client_id # only in case of OAuth 2.0, id of registered application on social service provider
- redirect_uri # to this url social provider will redirect with code
- scope=your_scope # for example email
- response_type=code # same for all oauth2.0 providers
Front-end redirect user to social authorize url with params from previous point.
User confirms.
Social provider redirects back to redirect_uri with param code.
Front-end now ready to login the user. To do it, send POST request with provider name and code:
```
 POST /api/login/social/session/
```
with data (form data or json)
```
 provider=facebook&code=AQBPBBTjbdnehj51
```
Backend will either signin the user, either signup, either return error.

Sometimes it is more suitable to specify provider in url, not in request body. It is possible, rest-social-auth will understand that. Following request is the same as above:
```
 POST /api/login/social/session/facebook/
```
with data (form data or json)
```
 code=AQBPBBTjbdnehj51
```

OAuth 1.0a workflow with rest-social-auth

Front-end needs to make a POST request to your backend with the provider name ONLY:
```
 POST /api/login/social/
```
with data (form data or json):
```
 provider=twitter
```
Or specify provider in url, in that case data will be empty:
```
 POST /api/login/social/twitter
```
The backend will return a short-lived oauth_token request token in the response. This can be used by the front-end to perform authentication with the provider.

User confirms. In the case of Twitter, they will then return the following data to your front-end:

 {
   "redirect_state":  "...bHrz2x0wy43",
   "oauth_token"   :  "...AAAAAAAhD5u",
   "oauth_verifier":  "...wDBdTR7CYdR"
 }

Front-end now ready to login the user. To do it, send POST request again with provider name and the oauth_token and oauth_verifier you got from the provider:
```
 POST /api/login/social/
```
with data (form data or json)
```
 provider=twitter&oauth_token=AQBPBBTjbdnehj51&oauth_verifier=wDBdTR7CYdR
```
Backend will either signin the user, or signup, or return an error. Same as in OAuth 2.0, you can specify provider in url, not in body:
```
 POST /api/login/social/twitter
```

This flow is the same as described in satellizer. This angularjs module is used in example project.

rest-social-auth purpose

As we can see, our backend must implement resource for signin the user.

Django REST social auth provides means to easily implement such resource.

List of oauth providers

OAuth 1.0 and OAuth 2.0 providers are supported.

Look python-social-auth for full list. Name of provider is taken from corresponding backend.name property of particular backed class in python-social-auth.

For example for facebook backend we see:

class FacebookOAuth2(BaseOAuth2):
    name = 'facebook'

Here are some provider names:

Provider	provider name
Facebook	facebook
Google	google-oauth2
Vkontakte	vk-oauth2
Instagram	instagram
Github	github
Yandex	yandex-oauth2
Twitter	twitter
Others	...

Settings

REST_SOCIAL_OAUTH_REDIRECT_URI

Default: '/'

Defines redirect_uri. This redirect must be the same in both authorize request (made by front-end) and access token request (made by back-end) to OAuth provider.

To override the relative path (url path or url name are both supported):
```
  REST_SOCIAL_OAUTH_REDIRECT_URI = '/oauth/redirect/path/'
  # or url name
  REST_SOCIAL_OAUTH_REDIRECT_URI = 'redirect_url_name'
```
Note, in case of url name, backend name will be provided to url resolver as argument.
REST_SOCIAL_DOMAIN_FROM_ORIGIN

Default: True

Sometimes front-end and back-end are run on different domains. For example frontend at 'myproject.com', and backend at 'api.myproject.com'.

If True, domain will be taken from request origin, if origin is defined. So in current example domain will be 'myproject.com', not 'api.myproject.com'. Next, this domain will be joined with path from REST_SOCIAL_OAUTH_REDIRECT_URI settings.

To be clear, suppose we have following settings (defaults):
```
  REST_SOCIAL_OAUTH_REDIRECT_URI = '/'
  REST_SOCIAL_DOMAIN_FROM_ORIGIN = True
```
Front-end is running on domain 'myproject.com', back-end - on 'api.myproject.com'. Back-end will use following redirect_uri:
```
  myproject.com/
```
And with following settings:
```
  REST_SOCIAL_OAUTH_REDIRECT_URI = '/'
  REST_SOCIAL_DOMAIN_FROM_ORIGIN = False
```
redirect_uri will be:
```
  api.myproject.com/
```
Also look at django-cors-headers if such architecture is your case.
REST_SOCIAL_OAUTH_ABSOLUTE_REDIRECT_URI

Default: None

Full redirect uri (domain and path) can be hardcoded
```
  REST_SOCIAL_OAUTH_ABSOLUTE_REDIRECT_URI = 'http://myproject.com/'
```
This settings has higher priority than REST_SOCIAL_OAUTH_REDIRECT_URI and REST_SOCIAL_DOMAIN_FROM_ORIGIN. I.e. if this settings is defined, other will be ignored. But redirect_uri param from request has higher priority than any setting.
REST_SOCIAL_LOG_AUTH_EXCEPTIONS

Default: True

When False will not log social auth authentication exceptions.
SOCIAL_AUTH_STRATEGY

Default: 'rest_social_auth.strategy.DRFStrategy'

Override strategy for python-social-auth.

Customization

First of all, customization provided by python-social-auth is also avaliable. For example, use nice mechanism of pipeline to do any action you need during login/signin.

Second, you can override any method from current package. Specify serializer for each view by subclassing the view.

To do it

define your own url:

  path('api/login/social/$', MySocialView.as_view(), name='social_login'),

define your serializer

  from rest_framework import serializers
  from django.contrib.auth import get_user_model

  class MyUserSerializer(serializers.ModelSerializer):

      class Meta:
          model = get_user_model()
          exclude = ('password', 'user_permissions', 'groups')

define view

  from rest_social_auth.views import SocialSessionAuthView
  from .serializers import MyUserSerializer

  class MySocialView(SocialSessionAuthView):
      serializer_class = MyUserSerializer

Check the code of the lib, there is not much of it.

Example

There is an example project.

clone repo

git clone https://github.com/st4lk/django-rest-social-auth.git

run example project
```
make
```
It is assumed, that you have:
- make
- docker
open https://127.0.0.1:8000/ in your browser

Note: runsslserver is used instead of built-in runserver to serve the project with TLS (aka SSL) certificate. HTTPS is required by some social providers (facebook), without it they won't work. The certificate will not be trusted by your system - that is expected. Just tell your browser to proceed with this untrusted certificate - it is acceptable for development purposes.

In Chrome browser it can look like this:
- step 1: image
- step 2: image
More details here.

Facebook, Google and Twitter auth should work, all secret keys are already set.

Example project uses satellizer angularjs module.

Development

Run tests locally

make test
