JWT token related configuration (global configuration identity authentication rewrites authenticate method)

One . jwt Global configuration

1.settings To configure

REST_FRAMEWORK = {
    
    #  Identity Authentication 
    'DEFAULT_AUTHENTICATION_CLASSES': (
    'rest_framework_jwt.authentication.JSONWebTokenAuthentication',),
}

import datetime
JWT_AUTH = {
    
    # jwt Expiration time difference  3 Days overdue 
    'JWT_EXPIRATION_DELTA': datetime.timedelta(days=3),
    #  Custom returned json data  **** Next, join 
    'JWT_RESPONSE_PAYLOAD_HANDLER': 'users.utils.jwt_response_payload_handler',
}

Two . To configure jwt Expiration time Custom returned json data

1.utils.py Function writing , Returns the specified format json data

users.utils.jwt_response_payload_handler: Created in users app Under the utils.py Of jwt_response_payload_handler function
Be careful : jwt_response_payload_handler The function needs to be written

  stay  users app Create utils.py  Then write 

#  Returns the specified format json data  token
def jwt_response_payload_handler(*args, **kwargs):
    print('args:', args)
    print('kwargs:', kwargs)
    token, user, request = args
    return {
    
        'code': 200,
        'username': user.username,
        'user_id': user.id,
        'token': token
    }

2.settings To configure

 settings  In the configuration file 

import datetime
JWT_AUTH = {
    
    # jwt Expiration time difference  3 Days overdue 
    'JWT_EXPIRATION_DELTA': datetime.timedelta(days=3),
    #  Custom returned json data 
    'JWT_RESPONSE_PAYLOAD_HANDLER': 'users.utils.jwt_response_payload_handler',
}

3、 ... and . To configure django Authentication back end of The purpose is to allow only administrators to log in Customize an authentication class rewrite Authenticate Method

users.utils.MyAuthentication: Created in users app Under the utils.py Of MyAuthentication class
Be careful : MyAuthentication Class needs to be written Inherit authentication parent ModelBackend

1.utils.py Class writing rewrite Authenticate Method

 stay  users app Create utils.py  Then write 

#  Only let administrators log in  
class MyAuthentication(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        #  Query user objects   You can login through password and mobile number 
        user = User.objects.filter(Q(username=username) | Q(phone=username)).first()
        #  Judge   user , password ,  Administrator or not 
        if user and check_password(password, user.password) and user.is_staff:
            return user    #  Verify that the object is returned   Otherwise return to None
        else:
            return None

2.settings To configure

 settings  In the configuration file 

AUTHENTICATION_BACKENDS = [
    'users.utils.MyAuthentication',  #  Custom authentication 
]

Four . Routing configuration

Do not inherit view classes , It is obtain_jwt_token
The interface shall be modified according to specific needs

urlpatterns = [
    
    #  Administrator login authentication 
    path('login/', obtain_jwt_token),
   
]

5、 ... and . Model class

1.models.py Define user classes in

#  User class 
class User(AbstractUser):
    phone = models.CharField(' cell-phone number ', max_length=11, null=True, unique=True, blank=True)
    last_login = models.DateTimeField(' Last login ',  null=True, blank=True)
    def __str__(self):
        return self.username

    class Meta:
        db_table = "user_tb"
        verbose_name_plural = ' User table '

2.settings To configure

#  Authenticated user model class 
AUTH_USER_MODEL = 'users.User'

3 Add test data

adopt python manage.py shell Ciphertext addition
