Package JWT

You need to create a folder under the root directory

Write code in it

    import jwt, time
    from django.conf import settings
    from django.utils.deprecation import MiddlewareMixin
     
    class UserMiddleware(MiddlewareMixin):
        def process_request(self, request):
     
            #  Get the information sent by the front desk 
            token = request.META.get('HTTP_TOKEN')
     
            #  Decrypt 
            try:
                user = jwt.decode(token, settings.SECRET_KEY, algorithms='HS256')
                #  Judge whether it is overdue 
                if user['exp'] < int(time.time()):
                    user = None
            except:
                user = None
     
            #  Insert to view at time 
            request.META['USER'] = user

In the configuration project

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware'
]
