我如何設置會話永遠不會在django中過期

Question

我正在使用Django-Python。有沒有辦法設置會話永不過期？

Answer 1

我不知道無限的會話，但如果您使用會話中間件 並使用巨大的AUTOLOGOUT時間，它將工作。

100年的聲音好嗎？在settings.py

# time in minutes 
# 60min*24hours*365days*100years 
AUTO_LOGOUT = 52560000 

創建一箇中間件，並將其添加在中間件部分

from datetime import datetime, timedelta 
from django.conf import settings 
from django.contrib import auth 
from django.utils.translation import ugettext as _ 

class AutoLogout: 

    def process_request(self, request): 

     if not request.user.is_authenticated(): 
      # Can't log out if is not logged in 
      return 
     try: 
      # last click 
      last_touch = datetime.strptime(request.session['last_touch'], "%Y-%m-%d %H:%M:%S.%f") 
      # getting auto logout time 
      auto_logout_time = settings.AUTO_LOGOUT 

      try: 
       if datetime.now() - last_touch > timedelta(0, auto_logout_time * 60, 0): 
        del request.session['last_touch'] 
        auth.logout(request) 
        request.session['warning'] = unicode(_("You have been logged out")) 
        return 
      except Exception as e: 
       # It should not reach this point 
       auth.logout(request) 
       del request.session['last_touch'] 
       request.session['warning'] = unicode(_("You have been logged out")) 

     except KeyError: 
      pass 

     request.session['last_touch'] = str(datetime.now())

由於Django的1.4（或更高版本）到settings.py中，你還可以設置通過在設置文件中設置SESSION_COOKIE_AGE來實現會話持續時間。

SESSION_COOKIE_AGE 
Default: 1209600 (2 weeks, in seconds) 
The age of session cookies, in seconds.
