Using with Django
Let's create authorization middleware.
Firstly, create variables in your settings.py:
Then implement middleware:
import logging
from django.conf import settings
from django.contrib.auth.models import User
from django.http import HttpRequest
from django.http import HttpResponse
from vk_miniapp_auth.auth import VKMiniAppAuthenticator
from vk_miniapp_auth.errors import InvalidInitDataError
from users.services import UserService
logger = logging.getLogger(__name__)
class VKMiniAppAuthorizationMiddleware:
def __init__(self, get_response) -> None:
self.get_response = get_response
self._vk_miniapp_authenticator = VKMiniAppAuthenticator(
settings.VK_APP_ID,
settings.VK_SECRET_TOKEN,
)
def __call__(self, request: HttpRequest) -> HttpResponse:
# Code to be executed for each request before
# the view (and later middleware) are called.
auth_cred = request.headers.get("Authorization")
if not auth_cred:
# TODO: handle error
pass
try:
launch_params = self._vk_miniapp_authenticator.get_launch_params(auth_cred)
except InvalidInitDataError:
# TODO: handle error
pass
if not launch_params or not launch_params.vk_user_id:
# TODO: handle error
pass
is_signed = self._vk_miniapp_authenticator.is_signed(launch_params)
if not is_signed:
# TODO: handle error
pass
else:
user, _ = UserService.get_or_create(launch_params.vk_user_id)
request.user = user
logger.debug("User was authorized using VK")
response = self.get_response(request)
# Code to be executed for each request/response after
# the view is called.
return response
To use VKMiniAppAuthorizationMiddleware, add it to your MIDDLEWARE setting in settings.py:
