如何在登录/注销时重新加载此页面？

So how can I force the page to reload at facebook connect / disconnect? Any other idea about this code? I tried the obvious javascript but that created a loop. Can you help me? Thanks

Update

I removed all Javascript and cookies since they are not needed and did a pure python solution with OAuth 2.0 to enable my scenario "login with facebook":

我删除了所有的Javascript和cookie,因为它们不需要,并使用OAuth 2.0做了一个纯python解决方案,以使我的场景“登录facebook”:

How to add Facebook as OAuth 2.0 provider: Here's how I make "Login with facebook" for my website with OAuth instead of javascript / cookie this is python only for OAuth 2.0 with Facebook and as far as I can tell it's working:

如何将Facebook添加为OAuth 2.0提供者:以下是我使用OAuth而不是javascript / cookie为我的网站制作“使用facebook登录”的方法这只是针对OAuth 2.0和Facebook的python,据我所知,它的工作原理如下:

class FBUser(db.Model):
    id = db.StringProperty(required=True)
    created = db.DateTimeProperty(auto_now_add=True)
    updated = db.DateTimeProperty(auto_now=True)
    name = db.StringProperty(required=True)
    profile_url = db.StringProperty()
    access_token = db.StringProperty(required=True)
    name = db.StringProperty(required=True)
    picture = db.StringProperty()
    email = db.StringProperty()
    friends = db.StringListProperty()

class I18NPage(I18NHandler):
    def get(self):
    if self.request.get('code'):
          args = dict(
            code = self.request.get('code'),
            client_id = facebookconf.FACEBOOK_APP_ID,
            client_secret = facebookconf.FACEBOOK_APP_SECRET,
            redirect_uri = 'http://www.koolbusiness.com/',
          )
      logging.debug("client_id"+str(args))
          file = urllib.urlopen("https://graph.facebook.com/oauth/access_token?" + urllib.urlencode(args))
          try:
        logging.debug("reading file")
            token_response = file.read()
        logging.debug("read file"+str(token_response))
          finally:
            file.close()
          access_token = cgi.parse_qs(token_response)["access_token"][-1]
          graph = main.GraphAPI(access_token)
          user = graph.get_object("me")   #write the access_token to the datastore
      fbuser = main.FBUser.get_by_key_name(user["id"])
          logging.debug("fbuser "+str(fbuser))

          if not fbuser:
            fbuser = main.FBUser(key_name=str(user["id"]),
                                id=str(user["id"]),
                                name=user["name"],
                                profile_url=user["link"],
                                access_token=access_token)
            fbuser.put()
          elif fbuser.access_token != access_token:
            fbuser.access_token = access_token
            fbuser.put()

The login link is

登录链接是

<a href="https://www.facebook.com/dialog/oauth?client_id=164355773607006&redirect_uri=http://{{host}}/"><img src="/_/img/loginwithfacebook.png"></a> that redirects and allows me to pick up the access_token in the method above and logout is straightforward:

如何在登录/注销时重新加载此页面？重定向并允许我在上面的方法中获取access_token并且注销很简单:

<a href="https://www.facebook.com/logout.php?next=http://www.koolbusiness.com&access_token={{access_token}}">{% trans "Log out" %}</a>

{%trans“退出”%}

If your page content has dependencies on events that occur after the pageload (ie Facebook login/logout) your best bet may be to use jQuery + ajax to load and/or reload the dependent elements separately.

如果您的页面内容依赖于页面加载后发生的事件(即Facebook登录/注销),您最好的选择可能是使用jQuery + ajax分别加载和/或重新加载依赖元素。
