REST framework's `Request` class extends the standard `HttpRequest`, adding support for REST framework's flexible request parsing and request authentication.
REST framework's Request objects provide flexible request parsing that allows you to treat requests with JSON data or other media types in the same way that you would normally deal with form data.
* It supports parsing the content of HTTP methods other than `POST`, meaning that you can access the content of `PUT` and `PATCH` requests.
* It supports REST framework's flexible request parsing, rather than just supporting form data. For example you can handle incoming JSON data in the same way that you handle incoming form data.
`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`.
For clarity inside your code, we recommend using `request.QUERY_PARAMS` instead of the usual `request.GET`, as *any* HTTP method type may include query parameters.
The `APIView` class or `@api_view` decorator will ensure that this property is automatically to a list of `Parser` instances, based on the `parser_classes` set on the view or based on the `DEFAULT_PARSERS` setting.
You won't typically need to access this property.

**Note:** If a client sends malformed content, then accessing `request.DATA` or `request.FILES` may raise a `ParseError`. By default REST framework's `APIView` class or `@api_view` decorator will catch the error and return a `400 Bad Request` response.
If a client sends a request with a content-type that cannot be parsed then a `UnsupportedMediaType` exception will be raised, which by default will be caught and return a `415 Unsupported Media Type` response.
`request.user` typically returns an instance of `django.contrib.auth.models.User`, although the behavior depends on the authentication policy being used.
If the request is unauthenticated the default value of `request.user` is an instance of `django.contrib.auth.models.AnonymousUser`.
For more details see the [authentication documentation].
`request.auth` returns any additional authentication context. The exact behavior of `request.auth` depends on the authentication policy being used, but it may typically be an instance of the token that the request was authenticated against.
The `APIView` class or `@api_view` decorator will ensure that this property is automatically to a list of `Authentication` instances, based on the `authentication_classes` set on the view or based on the `DEFAULT_AUTHENTICATORS` setting.
`request.content_type`, returns a string object representing the media type of the HTTP request's body, or an empty string if no media type was provided.
You won't typically need to directly access the request's content type, as you'll normally rely on REST framework's default request parsing behavior.
If you do need to access the content type of the request you should use the `.content_type` property in preference to using `request.META.get('HTTP_CONTENT_TYPE')`, as it provides transparent support for browser-based non-form content.
For more information see the [browser enhancements documentation].
## .stream
`request.stream` returns a stream representing the content of the request body.
If you do need to access the raw content directly, you should use the `.stream` property in preference to using `request.content`, as it provides transparent support for browser-based non-form content.
As REST framework's `Request` extends Django's `HttpRequest`, all the other standard attributes and methods are also available. For example the `request.META` dictionary is available as normal.
Note that due to implementation reasons the `Request` class does not inherit from `HttpRequest` class, but instead extends the class using composition.
