In Django, the request object contains a variety of information about the current HTTP request, including the query parameters. Query parameters are a way to pass additional information in the URL and are used to filter or sort data.

The request object provides a convenient way to access query parameters through the GET attribute.

The GET attribute is a dictionary-like object that allows you to access query parameters by key. You can use the GET attribute to access query parameters in the same way you would access a dictionary.

For example, if you have a query parameter named page domain/?page=101

you can access its value like this:

page = request.GET.get('page')

If the query parameter is not present in the request, request.GET.get() will return None. You can also provide a default value to be returned if the key is not found in the query parameters:

page = request.GET.get('page', 1)

You can also access all the query parameters as a dictionary using the GET.dict() method.

parameters = request.GET.dict()

It's also possible to access the query parameters using the request.GET as a dictionary.

parameters = request.GET

You can also use the request.GET.items() method to access all the query parameters as a list of key-value pairs.

parameters = request.GET.items()

When working with query parameters, it's important to validate and sanitize the data to prevent security vulnerabilities such as SQL injection. Django provides built-in forms that can be used to validate and sanitize query parameters consider going through them once.

In summary, the request object in Django provides a convenient way to access query parameters through the GET attribute. This attribute is a dictionary-like object that allows you to access query parameters by key. You can use the GET.get() method, GET.dict() method, GET.items() method or treat the GET attribute as a dictionary to capture query parameters.
