Django-facebook登录重定向后url的更改

我正在做一个服务器端登录到facebook，成功登录后，用户会被重定向到正确的位置和所有内容，但url在最后有一些特殊的标志

这是我的登录功能：

def fb_login(request):
    args = dict(client_id=FACEBOOK_APP_ID, redirect_uri=request.build_absolute_uri())

    # the user is already logged into facebook
    if 'code' in request.GET:
        args['client_secret'] = FACEBOOK_APP_SECRET
        args['code'] = request.GET.get('code')
        response = urlparse.parse_qs(urllib.urlopen("https://graph.facebook"
                                                ".com/oauth/access_token?" +
                                               urllib.urlencode(args)).read())
        # A short lived access token
        access_token = response['access_token'][0]

        # Extending the short lived access token
        args['grant_type'] = "fb_exchange_token"
        args['fb_exchange_token'] = access_token
        reponse2 = urlparse.parse_qs(urllib.urlopen("https://graph.facebook"
                                                ".com/oauth/access_token?" +
                                               urllib.urlencode(args)).read())

        token = Token.objects.create(token=reponse2['access_token'][0],
            expires_in=int(reponse2['expires'][0]))
        # do stuff with the token
        return HttpResponseRedirect(reverse('profile'))

    # the user is not logged into facebook yet
    else:
        return HttpResponseRedirect("https://graph.facebook.com/oauth/authorize?" +
                                    urllib.urlencode(args))

而不是此url：

http://localhost:8000/profile/

我明白了：

http://localhost:8000/profile/#_=_

什么会导致url像这样更改？

出于某些安全原因，登录流会将此哈希附加到当前地址。@CBroe Hmmm..interest。这在twitter登录后不会发生。我应该担心吗？看起来它不会影响任何东西，页面上的所有其他链接都正常工作。
