如何在登录/注销时重新加载此页面？ [英] How to make this page reload on login / logout?
问题描述
我试图使用户变量可用的服务，现在我注意到我的页面行为如果我重新加载，我想要的方式：
I tried to make the user variable available serveside and now I've noticed that my page behaves the way I want it if I reload:
那么如何强制该页面重新加载在Facebook连接/断开连接？关于这段代码的任何其他想法？我尝试了明显的JavaScript，但是创建了一个循环。你可以帮我吗？感谢
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

更新
我删除了所有的Javascript和cookie，因为它们不需要，并使用了一个纯粹的Python解决方案与OAuth 2.0，以启用我的方案用Facebook登录：
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":
如何添加Facebook作为OAuth 2.0提供商：这是我如何使用OAuth而不是javascript / cookie做为我的网站登录，这只是为了OAuth 2.0与Facebook，只要我能告诉它的工作：
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:
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()
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> 重定向并允许我在上面的方法中获取access_token，注销是直接的：
<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:
< a href =https://www.facebook.com/logout.php?next=http://www.koolbusiness.com&access_token={{access_token }}> {％trans注销％}< / a>
推荐答案
>如果您的页面内容依赖于在页面加载之后发生的事件（即Facebook登录/注销），您最好的选择是使用jQuery + ajax分别加载和/或重新加载依赖元素。
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.
