Python session on Google Cloud Run automatically logs out

问题

I am running a website on Google Cloud Run that I have written in Python. The site runs in a Docker image that uses python:latest. The code works, however after some time the user is logged out and I dont know why the session does not last.

main.py:

  1. """
  2. Main
  3. File: main.py
  4. Updated: 23.10.2022 Ditlefsen
  5. """
  6. import os
  8. import flask
  9. from flask import request, session
  11. # Flask
  12. app = flask.Flask(__name__)
  13. app.secret_key = os.urandom(12)
  16. # - Index ------------------------------------------------------------------------------
  17. @app.route('/', methods=['GET', 'POST'])
  18. def __index():
  20.     # Login user
  21.     if not session.get('logged_in'):
  22.         request_form_global = request.form
  24.         inp_username = request_form_global['inp_username']
  25.         inp_password = request_form_global['inp_password']
  27.         if inp_username == "hello" and inp_password == "world":
  28.             session['logged_in'] = True
  31.     if session.get('logged_in'):
  32.         return "Welcome to the website", 200
  33.     else:
  34.         return "Access denied!", 304
  37. # - Main ----------------------------------------------------------------------
  38. def main(function_request: flask.wrappers.Request = None):
  39.     app.run(debug=False, host="0.0.0.0", port=8080)
  41. if __name__ == '__main__':
  42.     main()

Dockerfile:

  1. # Specify Python
  2. FROM python:latest
  4. ENV PYTHONDONTWRITEBYTECODE 1
  5. ENV PYTHONUNBUFFERED 1
  7. # Open port
  8. EXPOSE 8080
  10. # Add Python script
  11. RUN mkdir /app
  12. WORKDIR /app
  13. COPY . .
  16. # Install dependencies
  17. RUN pip install -r requirements.txt
  19. # Set Python's path
  20. ENV PYTHONPATH /app
  22. # Run script
  23. CMD [ "python", "./main.py" ]

requirements.txt:

  1. cloud-sql-python-connector
  2. flask
  3. flask-cors
  4. google-cloud-secret-manager
  5. google
  6. google-api-python-client
  7. PyYAML
  8. psycopg2-binary
  9. pg8000
  10. sqlalchemy==1.4.46
  11. requests
  14. flask-login
  15. passlib
  16. Werkzeug

What can I do to keep the user logged in?

  • 如果您在本地测试代码，用户是否保持登录状态？
  • 登出之前的延迟是多少？
  • 我猜您的Google Cloud Run服务在一段时间后会关闭，这取决于您的订阅和/或参数（请参阅此处的配额）
英文:
  • Does your user remain logged in if you test your code locally?
  • What is the delay before being logged out?
    My guess is that your Google Cloud Run service is shut off after a while, depending on your subscription and/or parameters (see quotas here)
