How to clear cookies using Django

问题:

I am trying to develop login page for a web site. I am using Django 1.4.2. I stored users which logged on correctly to a cookie using set_cookie. But I didn't find clear_cookie in Django's documentation. How to clear a cookie to make a user log out?

回答1:

Setting cookies :

    def login(request):
        response = HttpResponseRedirect('/url/to_your_home_page')
        response.set_cookie('cookie_name1', 'cookie_name1_value')
        response.set_cookie('cookie_name2', 'cookie_name2_value')
        return response

Deleting cookies :

    def logout(request):
        response = HttpResponseRedirect('/url/to_your_login')
        response.delete_cookie('cookie_name1')
        response.delete_cookie('cookie_name2')
        return response

You can simply delete whatever you've stored in the cookie - this way, even though the cookie is there, it no longer contain any information required for session tracking and the user needs to authorize again.

(Also, this seems like a duplicate of Django logout(redirect to home page) .. Delete cookie?)
