add JSONRequestMiddleware to your enabled middleware in Django settings. Now, in your view functions, you can call request.json() to get a parsed json body! json is consumed lazily, and cached.

import json
from functools import lru_cache, partial
from django.http import HttpRequest
def _lazy_json(request):
    return json.loads(request.body)
def JSONRequestMiddleware(get_response):
    def middleware(request: HttpRequest):
        request.json = lru_cache(partial(_lazy_json, request))
        response = get_response(request)
        return response
    return middleware
