[Django learning] (16) session_token authentication process and difference _ response customization

1. Understanding session and token

Here is a direct reference to the article by the person, without explaining too much

Are session and token essentially the same in network applications? What's the difference? - Know almost

2. Token response customization

Configured in the global configuration table

'DEFAULT_AUTHENTICATION_CLASSES': [
        # 指定jwt Token认证
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication'
'JWT_PAYLOAD_HANDLER':
        'rest_framework_jwt.utils.jwt_payload_handler',

rest_framework_jwt/views.py中

​

 ​url.py of the users

Quote obtain_jwt_token

from django.urls import path
from interfaces import views
from  rest_framework_jwt.views import obtain_jwt_token

urlpatterns = [

    path('login/', obtain_jwt_token)
]

 It is found that there is a post method in rest_framework_jwt/views.py:

​

 After logging in, it is found that the output only returns the token field

 If we want user_id and user_name to be output as well, we need to customize the output

Check the post method in rest_framework_jwt/views.py to call the jwt_response_payload_handler method

​ 

 ​

 ​

 If you don't need to rewrite, you can directly reference it in the project setting.py file

JWT_AUTH={
    'JWT_RESPONSE_PAYLOAD_HANDLER':
        'rest_framework_jwt.utils.jwt_response_payload_handler',
}

 Finally found jwt_response_payload_handler in rest_framework_jwt.utils.py file

​

 So we have to rewrite this method:

Create a new handler_jwt_response.py in the utils folder of the local project

def jwt_response_payload_handler(token, user=None, request=None):
    """
    Returns the response data for both the login and refresh views.
    Override to return a custom response such as including the
    serialized representation of the User.

    Example:

    def jwt_response_payload_handler(token, user=None, request=None):
        return {
            'token': token,
            'user': UserSerializer(user, context={'request': request}).data
        }

    """
    return {
        'user_id': user.id,
        'user_name': user.username,
        'token': token
    }

 After rewriting, also modify the reference path in the global configuration table

JWT_AUTH={
    'JWT_RESPONSE_PAYLOAD_HANDLER':
        # 'rest_framework_jwt.utils.jwt_response_payload_handler',
        'utils.handler_jwt_response.jwt_response_payload_handler',
}

Run to get the desired result
