django - 在用户注销后存储 session 值

Question

使用 Django logout当用户注销时，所有 session 值都会被刷新。
即使用户注销，我有没有办法保留一些 session 值？

Answer 1

您可能希望使用 cookie 而不是 session 来实现这一点。

# views.py, login view
# After you have authenticated a user
username = 'john.smith'  # Grab this from the login form

# If you want the cookie to last even if the user closes his browser,
# set max_age to a very large value, otherwise don't use max_age.
response = render_to_response(...)
response.set_cookie('the_current_user', username, max_age=9999999999)

在您的登录 View 中:

remembered_username = request.COOKIES.get('the_current_user', '')

将上面的内容推送到模板中显示:

Hello {{ remembered_username }}
