Question

我在做那个

$ rootScope.img =“http://graph.facebook.com/”+ success.authResponse.userID +“/ picture？type = large”;

我在横向菜单上有这个

 <a class="item item-avatar" data-componentid="html9" style="
    border-top-width: 0px;
    border-bottom-width: 0px;
    border-left-width: 0px;
    border-right-width: 0px;">
             <img  ng-model="avatar" ng-src="{{ img }}" style="max-width: 50px; max-height: 50px;">

</a>

问题是当我登录并从Facebook获取图像时，它不会在视图上刷新。

制作research on the official docs，我找到了这个解决方案：

 FB.getLoginStatus(function(response) {
   if (response.status === 'connected') {
     var uid = response.authResponse.userID;
     $rootScope.img= "http://graph.facebook.com/" + uid + "/picture?type=large";
   } else if (response.status === 'not_authorized') {
     // the user is logged in to Facebook, 
     // but has not authenticated your app
   } else {
     // the user isn't logged in to Facebook.
   }
 });

FB.getLoginStatus()可让您确定用户是否已登录Facebook并已对您的应用进行身份验证。
