"detail": "未提供身份验证凭据。" 创建新用户时

Question

I am attempting to create a new user in my platform when they sign up for my app. I want them to enter their details and send it up to the server to create the account so they can sign in and then receive a token. Whenever I use postman to send up the credentials I get this error:

"detail": "Authentication credentials were not provided."

This is what I have so far:

Settings.py :

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',

    ),
}

    return {

        serializer = AppSignUpSerializer(data=request.data)
        data = {}
        if serializer.is_valid():

    email = serializers.EmailField(
            required=True,

            )
    username = serializers.CharField(

            )
    password = serializers.CharField(min_length=6, max_length=100,
            write_only=True)

    def save(self):

        user.set_password(password)

This is because your global DRF settings is applied to the createApp_user view also.

What you have to do is, provide empty permission_classes and authentication_classes settings to your view by corresponding decorators, as below

@api_view(['POST', ])

def createApp_user(request):
    ...
    # your rest of the code
