[Django]-How to get username from Django Rest Framework JWT token

For me, this worked as RestFrameworkJWT is no longer maintained.
So I used the rest_framework_simplejwt package.

from rest_framework_simplejwt.backends import TokenBackend
token = request.META.get('HTTP_AUTHORIZATION', " ").split(' ')[1]
data = {'token': token}
   try:
      valid_data = TokenBackend(algorithm='HS256').decode(token,verify=True)
      user = valid_data['user']
      request.user = user
   except ValidationError as v:
      print("validation error", v)

For me with Django (2.0.1), djangorestframework (3.7.7), djangorestframework-jwt (1.11.0).

I had to do following to get my use back user from token:

        token = request.META.get('HTTP_AUTHORIZATION', " ").split(' ')[1]
        print(token)
        data = {'token': token}
        try:
            valid_data = VerifyJSONWebTokenSerializer().validate(data)
            user = valid_data['user']
            request.user = user
        except ValidationError as v:
            print("validation error", v)

Or you can write a middleware that would set user based on their token.

If you are using djangorestframework_simplejwt, to get user object from JWT Token you need to do the following :

token = AccessToken(access_token)
user_id = token.payload['user_id']
user = User.objects.get(id=user_id)

This works well !!
