Views code and details

Generic

Generic views are intended to use in a “batteries included” fashion to protect own views with OAuth2 authentication and Scopes handling.

class oauth2_provider.views.generic.ClientProtectedResourceView(**kwargs)

View for protecting a resource with client-credentials method. This involves allowing access tokens, Basic Auth and plain credentials in request body.

class oauth2_provider.views.generic.ClientProtectedScopedResourceView(**kwargs)

Impose scope restrictions if client protection fallsback to access token.

class oauth2_provider.views.generic.ProtectedResourceView(**kwargs)

Generic view protecting resources by providing OAuth2 authentication out of the box

class oauth2_provider.views.generic.ReadWriteScopedResourceView(**kwargs)

Generic view protecting resources with OAuth2 authentication and read/write scopes. GET, HEAD, OPTIONS http methods require “read” scope. Otherwise “write” scope is required.

class oauth2_provider.views.generic.ScopedProtectedResourceView(**kwargs)

Generic view protecting resources by providing OAuth2 authentication and Scopes handling out of the box

Mixins

These views are mainly for internal use, but advanced users may use them as basic components to customize OAuth2 logic inside their Django applications.

class oauth2_provider.views.mixins.ClientProtectedResourceMixin

Mixin for protecting resources with client authentication as mentioned in rfc:3.2.1 This involves authenticating with any of: HTTP Basic Auth, Client Credentials and Access token in that order. Breaks off after first validation.

class oauth2_provider.views.mixins.OAuthLibMixin

This mixin decouples Django OAuth Toolkit from OAuthLib.

Users can configure the Server, Validator and OAuthlibCore classes used by this mixin by setting the following class variables:

  • server_class
  • validator_class
  • oauthlib_backend_class

If these class variables are not set, it will fall back to using the classes specified in oauth2_settings (OAUTH2_SERVER_CLASS, OAUTH2_VALIDATOR_CLASS and OAUTH2_BACKEND_CLASS).

authenticate_client(request)

Returns a boolean representing if client is authenticated with client credentials method. Returns True if authenticated.

Parameters:request – The current django.http.HttpRequest object
create_authorization_response(request, scopes, credentials, allow)

A wrapper method that calls create_authorization_response on server_class instance.

Parameters:
  • request – The current django.http.HttpRequest object
  • scopes – A space-separated string of provided scopes
  • credentials – Authorization credentials dictionary containing client_id, state, redirect_uri and response_type
  • allow – True if the user authorize the client, otherwise False
create_revocation_response(request)

A wrapper method that calls create_revocation_response on the server_class instance.

Parameters:request – The current django.http.HttpRequest object
create_token_response(request)

A wrapper method that calls create_token_response on server_class instance.

Parameters:request – The current django.http.HttpRequest object
create_userinfo_response(request)

A wrapper method that calls create_userinfo_response on the server_class instance.

Parameters:request – The current django.http.HttpRequest object
error_response(error, **kwargs)

Return an error to be displayed to the resource owner if anything goes awry.

Parameters:errorOAuthToolkitError
classmethod get_oauthlib_backend_class()

Return the OAuthLibCore implementation class to use

classmethod get_oauthlib_core()

Cache and return OAuthlibCore instance so it will be created only on first request unless ALWAYS_RELOAD_OAUTHLIB_CORE is True.

get_scopes()

This should return the list of scopes required to access the resources. By default it returns an empty list.

classmethod get_server()

Return an instance of server_class initialized with a validator_class object

classmethod get_server_class()

Return the OAuthlib server class to use

classmethod get_validator_class()

Return the RequestValidator implementation class to use

validate_authorization_request(request)

A wrapper method that calls validate_authorization_request on server_class instance.

Parameters:request – The current django.http.HttpRequest object
verify_request(request)

A wrapper method that calls verify_request on server_class instance.

Parameters:request – The current django.http.HttpRequest object
class oauth2_provider.views.mixins.OIDCOnlyMixin

Mixin for views that should only be accessible when OIDC is enabled.

If OIDC is not enabled:

  • if DEBUG is True, raises an ImproperlyConfigured exception explaining why
  • otherwise, returns a 404 response, logging the same warning
class oauth2_provider.views.mixins.ProtectedResourceMixin

Helper mixin that implements OAuth2 protection on request dispatch, specially useful for Django Generic Views

class oauth2_provider.views.mixins.ReadWriteScopedResourceMixin

Helper mixin that implements “read and write scopes” behavior

get_scopes(*args, **kwargs)

Return the scopes needed to access the resource

Parameters:args – Support scopes injections from the outside (not yet implemented)
class oauth2_provider.views.mixins.ScopedResourceMixin

Helper mixin that implements “scopes handling” behaviour

get_scopes(*args, **kwargs)

Return the scopes needed to access the resource

Parameters:args – Support scopes injections from the outside (not yet implemented)

Base

Views needed to implement the main OAuth2 authorization flows supported by Django OAuth Toolkit.

class oauth2_provider.views.base.AuthorizationView(**kwargs)

Implements an endpoint to handle Authorization Requests as in RFC6749 Section 4.1.1 and prompting the user with a form to determine if she authorizes the client application to access her data. This endpoint is reached two times during the authorization process: * first receive a GET request from user asking authorization for a certain client application, a form is served possibly showing some useful info and prompting for authorize/do not authorize.

  • then receive a POST request possibly after user authorized the access

Some informations contained in the GET request and needed to create a Grant token during the POST request would be lost between the two steps above, so they are temporarily stored in hidden fields on the form. A possible alternative could be keeping such informations in the session.

The endpoint is used in the following flows: * Authorization code * Implicit grant

form_class

alias of oauth2_provider.forms.AllowForm

form_valid(form)

If the form is valid, redirect to the supplied URL.

get(request, *args, **kwargs)

Handle GET requests: instantiate a blank version of the form.

get_initial()

Return the initial data to use for forms on this view.

class oauth2_provider.views.base.BaseAuthorizationView(**kwargs)

Implements a generic endpoint to handle Authorization Requests as in RFC6749 Section 4.1.1. The view does not implement any strategy to determine authorize/do not authorize logic. The endpoint is used in the following flows:

  • Authorization code
  • Implicit grant
error_response(error, application, **kwargs)

Handle errors either by redirecting to redirect_uri with a json in the body containing error details or providing an error response

class oauth2_provider.views.base.RevokeTokenView(**kwargs)

Implements an endpoint to revoke access or refresh tokens

class oauth2_provider.views.base.TokenView(**kwargs)

Implements an endpoint to provide access tokens

The endpoint is used in the following flows: * Authorization code * Password * Client credentials
