## OAuthAuthentication
This authentication uses [OAuth 1.0a][oauth-1.0a] authentication scheme. It depends on the optional `django-oauth-plus` and `oauth2` packages. In order to make it work you must install these packages and add `oauth_provider` to your `INSTALLED_APPS`:
This authentication uses [OAuth 1.0a][oauth-1.0a] authentication scheme. OAuth 1.0a provides signature validation which provides a reasonable level of security over plain non-HTTPS connections. However, it may also be considered more complicated than OAuth2, as it requires clients to sign their requests.
This authentication class depends on the optional `django-oauth-plus` and `oauth2` packages. In order to make it work you must install these packages and add `oauth_provider` to your `INSTALLED_APPS`:
INSTALLED_APPS = (
...
`oauth_provider`,
)
OAuthAuthentication class provides only token verification and signature validation for requests. It doesn't provide authorization flow for your clients. You still need to implement your own views for accessing and authorizing Reqest/Access Tokens. This is because there are many different OAuth flows in use. Almost always they require end-user interaction, and most likely this is what you want to design yourself.
Don't forget to run `syncdb` once you've added the package.
python manage.py syncdb
#### Getting started with django-oauth-plus
The `django-oauth-plus` package provides simple foundation for classic 'three-legged' oauth flow, so if it is what you need please refer to [its documentation][django-oauth-plus]. This documentation will provide you also information about how to work with supplied models and change basic settings.

## OAuth2Authentication
This authentication uses [OAuth 2.0][rfc6749] authentication scheme. It depends on the optional [django-oauth2-provider][django-oauth2-provider] project. In order to make it work you must install this package and add `provider` and `provider.oauth2` to your `INSTALLED_APPS` :

`OAuth2Authentication` class provides only token verification for requests. The *oauth 2 dance* is taken care by the [django-oaut2-provider][django-oauth2-provider] dependency. The official [documentation][django-oauth2-provider--doc] is being [rewritten][django-oauth2-provider--rewritten-doc].

The Good news is, here is a minimal "How to start" because **OAuth 2** is dramatically simpler than **OAuth 1**, so no more headache with signature, cryptography on client side, and other complex things.
**Note:** If you use `OAuth2Authentication` in production you must ensure that your API is only available over `https` only.

#### Getting started with django-oauth2-provider
1. Create a client in the django-admin panel
The `OAuth2Authentication` class only provides token verification for requests. It doesn't provide authorization flow for your clients.
The OAuth 2 authorization flow is taken care by the [django-oauth2-provider][django-oauth2-provider] dependency. A walkthrough is given here, but for more details you should refer to [the documentation][django-oauth2-provider-docs].
To get started:
##### 1. Create a client
You can create a client, either through the shell, or by using the Django admin.
Go to the admin panel and create a new `Provider.Client` entry. It will create the `client_id` and `client_secret` properties for you.
2. Request an access token
##### 2. Request an access token
To request an access toke, submit a `POST` request to the url `/oauth2/access_token` with the following fields :
To request an access token, submit a `POST` request to the url `/oauth2/access_token` with the following fields:
* `client_id` the client id you've just configured at the previous step.
* `client_secret` again configured at the previous step.
* `username` the username with which you want to log in.
* `password` well, that speaks for itself.

You can use the command line to test that your local configuration is working:
**Note:** Remember that you should use HTTPS in production.
curl -X POST -d "client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=password&username=YOUR_USERNAME&password=YOUR_PASSWORD" http://localhost:8000/oauth2/access_token/

$ curl -X POST -d "client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=password&username=YOUR_USERNAME&password=YOUR_PASSWORD" http://localhost:8000/oauth2/access_token/
Here is the response you should get :
You should get a response that looks something like this:
{"access_token": "<your-access-token>", "scope": "read", "expires_in": 86399, "refresh_token": "<your-refresh-token>"}
3. Access the api

The only thing needed to make the `OAuth2Authentication` class work is to insert the `access_token` you've received in the `Authorization` api request header.
