How to access get request data in django rest framework

Question

How to access GET request data in django rest framework. In the docs, they have mentioned "For clarity inside your code, we recommend using request.query_params instead of the Django's standard request.GET"

https://www.django-rest-framework.org/api-guide/requests/

But when I use request.query_params.get('some_vaue') it gives me none even though I pass the data in the request body.

sample code example:

class TestView(APIView):
    def get(self, request):
        test = request.query_params.get('test')
        print('data',test)
        ...
        ...
        ...

When I pass some value in the body of the request in postman and print the value, it actually prints None.

Update

Below is my axios code

 axios.get(API_URL, {
            headers: {
                'Content-Type': 'application/json'
            },
            params: {
                page_num: 1, 
                test: 'test data'
            }
        })
        .then(res => {
            console.log(res);
        })
        .catch(err => {
            console.log(err.response.data);
        });

Re-Update:

For testing purpose I printed out the request object like

print(request.__dict__)

so it printed out

{'_request': <WSGIRequest: GET '/api/my api url/?page_num=1&test=test+data'>, 'parsers': [<rest_framework.parsers.JSONParser object at 0x0000016742098128>, <rest_framework.parsers.FormParser object at 0x00000167420980B8>, <rest_framework.parsers.MultiPartParser object at 0x00000167420980F0>], 'authenticators': (), 'negotiator': <rest_framework.negotiation.DefaultContentNegotiation object at 0x0000016742098080>, 'parser_context': {'view': <app_name.views.APIClassName object at 0x0000016742280400>, 'args': (), 'kwargs': {}, 'request': <rest_framework.request.Request object at 0x0000016742107080>, 'encoding': 'utf-8'}, '_data': {}, '_files': <MultiValueDict: {}>, '_full_data': {}, '_content_type': <class 'rest_framework.request.Empty'>, '_stream': None, 'accepted_renderer': <rest_framework.renderers.JSONRenderer object at 0x00000167421070B8>, 'accepted_media_type': 'application/json', 'version': None, 'versioning_scheme': None, '_authenticator': None, '_user': <django.contrib.auth.models.AnonymousUser object at 0x0000016741FFAC88>, '_auth': None}

I could see that it is passing the data but not sure why if i do request.data['page_num'] or any other value it doesn't get the data.

If you are using class based views :

POST provides data in request.data and GET in request.query_params

If you are using function based views:

request.data will do the work for both methods.

axios does not support sending params as body with get method , it will append params in url. so if you are using axios you will have to use query_params

Axios example code:

axios.get(API_URL, {
            params: {
                testData: 'test data',
                pageNum: 1
            }
        })
        .then(res => {
            console.log(res);
        })
        .catch(err => {
            console.log(err.response.data);
        });

DRF example code:

Class TestView(APIView):
    def get(self, request):
        test_data_var = request.query_params['testData']
        page_num_var = request.query_params['pageNum']

Note: If you're testing it in postman then put the get request query params in Params tab.
