===========
|
|
|
|
This example will show how you can protect your api by using authentication
|
|
and how you can limit the amount of requests a user can do to a resource by setting
|
|
a throttle to your view.
|
|
|
|
Authentication
|
|
--------------
|
|
|
|
If you want to protect your api from unauthorized users, Django REST Framework
|
|
offers you two default authentication methods:
|
|
|
|
* Basic Authentication
|
|
* Django's session-based authentication
|
|
|
|
These authentication methods are by default enabled. But they are not used unless
|
|
you specifically state that your view requires authentication.
|
|
|
|
To do this you just need to import the `Isauthenticated` class from the frameworks' `permissions` module.::
|
|
|
|
from djangorestframework.permissions import IsAuthenticated
|
|
|
|
Then you enable authentication by setting the right 'permission requirement' to the `permissions` class attribute of your View like
|
|
the example View below.:
|
|
|
|
|
|
.. literalinclude:: ../../examples/permissionsexample/views.py
|
|
:pyobject: LoggedInExampleView
|
|
|
|
The `IsAuthenticated` permission will only let a user do a 'GET' if he is authenticated. Try it
|
|
yourself on the live sandbox__
|
|

|
|
|
|
|
|
Throttling
|
|
----------
|
|
|
|
If you want to limit the amount of requests a client is allowed to do on
|
|
a resource, then you can set a 'throttle' to achieve this.
|
|
|
|
For this to work you'll need to import the `PerUserThrottling` class from the `permissions`
|
|
module.::
|
|
|
|
from djangorestframework.permissions import PerUserThrottling
|
|
|
|
In the example below we have limited the amount of requests one 'client' or 'user'
|
|
may do on our view to 10 requests per minute.:
|
|
|
|
.. literalinclude:: ../../examples/permissionsexample/views.py
|
|
:pyobject: ThrottlingExampleView
|
|
|
|
Try it yourself on the live sandbox__.
|
|
|
|
__ http://rest.ep.io/permissions-example/throttling
|
|
|
|
Now if you want a view to require both aurhentication and throttling, you simply declare them
|
|
both::
|
|
|
|
permissions = (PerUserThrottling, Isauthenticated)
|
|
|
|
To see what other throttles are available, have a look at the :mod:`permissions` module.
|
|
|
|
If you want to implement your own authentication method, then refer to the :mod:`authentication`
|
|
module.
