I am trying to make an API in Django that returns employee info as JSON only when a user is logged in.
My question is, how can I make a user registration and log in option without the use of html and forms?
Is there a way for me to create a registration option that takes in input sent by a client via JSON. For example, a POST request to localhost:example/register/ which contained :
{"username" : "examle", "email" : "example", "password" : "example", "password2" : "example"}?
How would this be implemented in views.py?
Any help would be appreciated.
Thank you.

Yes, there is a way, and Django Rest Framework includes almost everything you need.
To answer your first question about being logged in, you would add a permissions class to only allow access to someone who is authenticated.
To answer your API question for registration, you'll want to create an API endpoint in whichever URL file is relevant; I put my in my Users app:
urlpatterns = [
path('register/', register_user_view, name="register"),
...
]
You'll want to create a view and serializer to ingest the JSON you're sending in:
#api_view(['POST',])
def register_user_view(request):
if request.method == 'POST':
serializer = RegistrationSerializer(data=request.data)
data = {}
if serializer.is_valid():
account = serializer.save()
data['response'] = "successfully registered a new user."
data['email'] = account.email
data['response'] = account.username
else:
data = serializer.errors
# data = serializer.data
return Response(data)
Serializer:
class RegistrationSerializer(serializers.ModelSerializer):
password2 = serializers.CharField(style={'input_type': 'password'}, write_only=True)
class Meta:
model = CustomUser
fields = ['email', 'username', 'password', 'password2']
extra_kwargs = {
'password': {'write_only': True}
}
def save(self):
account = CustomUser(
email=self.validated_data['email'],
username=self.validated_data['username'],
)
password = self.validated_data['password']
password2 = self.validated_data['password2']
if password != password2:
raise serializers.ValidationError({'password': 'Passwords do not match!'})
account.set_password(password)
account.save()
return account
