如何在注销后将Plone设置为重定向到came_from

I want to set a plone website to redirect to came_from parameter in url after user logout. For login I set string:${globals_view/navigationRootUrl}/login?came_from=${context/absolute_url} and it is working.

我想设置一个plone网站,在用户注销后重定向到url中的came_from参数。对于登录我设置字符串:$ {globals_view / navigationRootUrl} / login?came_from = $ {context / absolute_url}并且它正在工作。

For logout this is not working. I tried also with its event:

对于注销,这不起作用。我也试过它的事件:

  <subscriber
    for="Products.PlonePAS.events.UserLoggedOutEvent"
    handler="blabla.goCameFromAfterLogout"
    />

using:

def goCameFromAfterLogout(event):
    """ Redirects user to came_from url parameter after logout
    """
    import pdb; pdb.set_trace( )
    request = event.object.REQUEST
    came_from = request.form.get('came_from', None)
    if came_from:
        response = request.RESPONSE
        response.redirect(came_from)

The event is ok, the came_from parameter is ok, but the code is not working how I want. The website redirects me to /logged_out every time.

事件没问题,came_from参数没问题,但代码不能正常工作。该网站每次都会将我重定向到/ logged_out。

So, how can I set this?

那么,我该怎么设置呢?

3 个解决方案

#1

A simple way: customize logged_out, transform it to a Python Script that redirect to whatever page you want:

一种简单的方法:自定义logged_out,将其转换为Python脚本,重定向到您想要的任何页面:

context.REQUEST.RESPONSE.redirect(url)

#2

You can also raise a Redirect exception in your event handler

您还可以在事件处理程序中引发重定向异常

from zExceptions import Redirect

def goCameFromAfterLogout(event):
""" Redirects user to came_from url parameter after logout
"""
request = event.object.REQUEST
came_from = request.form.get('came_from', None)
if came_from:
    raise Redirect(came_from)

Also ?next=url instead of came_from is a good idea.

还有?next = url而不是came_from是一个好主意。
