The `Request` object in `djangorestframework` extends the standard `HttpRequest`, adding support for parsing multiple content types, allowing browser-based `PUT`, `DELETE` and other methods, and adding flexible per-request authentication.
|
||
|
|
|
||
|
|
method
|
||
|
|
------
|
||
|
|
|
||
|
|
`request.method` returns the uppercased string representation of the request's HTTP method.
|
||
|
|
|
||
|
|
Browser-based `PUT`, `DELETE` and other requests are supported, and can be made by using a hidden form field named `_method` in a regular `POST` form.
|
||
|
|

|
||
|
|
content_type
|
||
|
|
------------
|
||
|
|
|
||
|
|
`request.content`, returns a string object representing the mimetype of the HTTP request's body, if one exists.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
DATA
|
||
|
|
----
|
||
|
|
|
||
|
|
`request.DATA` returns the parsed content of the request body. This is similar to the standard `HttpRequest.POST` attribute except that:
|
||
|
|
|
||
|
|
1. It supports parsing the content of HTTP methods other than `POST`, meaning that you can access the content of `PUT` and `PATCH` requests.
|
||
|
|
2. It supports parsing multiple content types, rather than just form data. For example you can handle incoming json data in the same way that you handle incoming form data.
|
||
|
|
|
||
|
|
FILES
|
||
|
|
-----
|
||
|
|
|
||
|
|
`request.FILES` returns any uploaded files that may be present in the content of the request body. This is the same as the standard `HttpRequest` behavior, except that the same flexible request parsing that is used for `request.DATA`.
|
||
|
|
|
||
|
|
This allows you to support file uploads from multiple content-types. For example you can write a parser that supports `POST`ing the raw content of a file, instead of using form-encoded file uploads.
|
||
|
|
|
||
|
|
user
|
||
|
|
----
|
||
|
|
|
||
|
|
`request.user` returns a `django.contrib.auth.models.User` instance.
|
||
|
|
|
||
|
|
auth
|
||
|
|
----
|
||
|
|
|
||
|
|
`request.auth` returns any additional authentication context that may not be contained in `request.user`. The exact behavior of `request.auth` depends on what authentication has been set in `request.authentication`. For many types of authentication this will simply be `None`, but it may also be an object representing a permission scope, an expiry time, or any other information that might be contained in a token-based authentication scheme.
|
||
|
|
|
||
|
|
parsers
|
||
|
|
-------
|
||
|
|
|
||
|
|
`request.parsers` should be set to a list of `Parser` instances that can be used to parse the content of the request body.
|
||
|
|
|
||
|
|
`request.parsers` may no longer be altered once `request.DATA`, `request.FILES` or `request.POST` have been accessed.
|
||
|
|
|
||
|
|
If you're using the `djangorestframework.views.View` class... **[TODO]**
|
||
|
|
|
||
|
|
stream
|
||
|
|
------
|
||
|
|
|
||
|
|
`request.stream` returns a stream representing the content of the request body.
|
||
|
|
|
||
|
|
You will not typically need to access `request.stream`, unless you're writing a `Parser` class.
|
||
|
|
|
||
|
|
authentication
|
||
|
|
--------------
|
||
|
|
|
||
|
|
`request.authentication` should be set to a list of `Authentication` instances that can be used to authenticate the request.
|
||
|
|
|
||
|
|
`request.authentication` may no longer be altered once `request.user` or `request.auth` have been accessed.
|
||
|
|
|
||
|
|
