What I tried to do:

1. In my main project folder I have directory downloadable_app with these files/folders inside:
   
   
   • index.html
   
   
   • js/app.f54b97d7097bcf4226c0.js
   
   


2. I need to allow users to download this downloadable_app folder as zip archive


3. In app.f54b97d7097bcf4226c0.js file I have axios.defaults.headers.common['Authorization'] = 'Bearer <BEARER_TOKEN>'
   


4. I need to replace <BEARER_TOKEN> by request.user token

This is how I did this:

settings.py:

PROJECT_PATH = os.path.abspath(os.path.dirname(__name__))
DOWNLOADABLE_APP_ROOT = os.path.join(PROJECT_PATH, 'downloadable_app')

views.py:

import datetime
import binascii
import os
from datetime import timedelta
import shutil
...

from oauth2_provider.models import Application, AccessToken


class DownloadAppView(LoginRequiredMixin, View):
 def dispatch(self, request, *args, **kwargs):
 if not self.request.user.plan:
 raise Http404
 self.token = self._get_or_create_user_token()
 return super(DownloadAppView, self).dispatch(
 request, *args, **kwargs)

 def _add_token_to_downloadable_app(self, token):
 with open(os.path.join(settings.DOWNLOADABLE_APP_ROOT, 'js/app.f54b97d7097bcf4226c0.js'), 'r') as file:
 filedata = file.read()

 filedata = filedata.replace('<BEARER_TOKEN>', token)

 with open(os.path.join(settings.DOWNLOADABLE_APP_ROOT, 'js/app.f54b97d7097bcf4226c0.js'), 'w') as file:
 file.write(filedata)

 def _reset_token_in_downloadable_app(self, token):
 with open(os.path.join(settings.DOWNLOADABLE_APP_ROOT, 'js/app.f54b97d7097bcf4226c0.js'), 'r') as file:
 filedata = file.read()

 filedata = filedata.replace(token, '<BEARER_TOKEN>')

 with open(os.path.join(settings.DOWNLOADABLE_APP_ROOT, 'js/app.f54b97d7097bcf4226c0.js'), 'w') as file:
 file.write(filedata)

 def _get_or_create_user_token(self):
 app, created = Application.objects.get_or_create(
 client_type=Application.CLIENT_CONFIDENTIAL,
 authorization_grant_type=Application.GRANT_CLIENT_CREDENTIALS,
 redirect_uris='https://www.example.com/',
 name='downloadable_app',
 user=User.objects.filter(is_superuser=True, is_staff=True).first()
 )
 access_token, created = AccessToken.objects.get_or_create(
 user=self.request.user,
 scope='read write',
 application=app,
 defaults='expires': timezone.now() + timedelta(days=1000), 'token': binascii.hexlify(os.urandom(20)).decode()
 )
 return access_token.token

 def get(self, request):
 self._add_token_to_downloadable_app(self.token)

 # create_zip_archive
 shutil.make_archive('downloadable_app_archives/my_app_'.format(request.user.pk), 'zip', settings.DOWNLOADABLE_APP_ROOT)
 response = HttpResponse(
 open(os.path.join(
 settings.PROJECT_PATH, 'downloadable_app_archives/my_app_.zip'.format(request.user.pk)), 'rb').read(), content_type='application/zip')
 self._reset_token_in_downloadable_app(self.token)
 return response

management.commands.delete_zip_archives.py:

class Command(BaseCommand):
 help = 'Delete downloadable app zip archives'

 def handle(self, *args, **options):
 shutil.rmtree(os.path.join(settings.PROJECT_PATH, 'downloadable_app_archives'))

Can you please take a look and let me know how can I improve this?
