从FB.ui获取Facebook用户Uid

Question

我有这段代码：

 FB.ui(
  {
    method: 'stream.publish',
    attachment: {
      name: 'JSSDK',
      caption: 'The Facebook JavaScript SDK',
      description: (
        'A small JavaScript library that allows you to harness ' +
        'the power of Facebook, bringing the user\'s identity, ' +
        'social graph and distribution power to your site.'
      ),
      href: 'http://fbrell.com/'
    },
    action_links: [
      { text: 'fbrell', href: 'http://fbrell.com/' }
    ]
  },
  function(response) {
    if (response && response.post_id) {

/* 
   HERE
*/
      alert('Post was published.');
    } else {
      alert('Post was not published.');
    }
  }
);

在Here Point中，我如何获得用户uid？ 我试过：

var user_id = FB.getSession（）。uid;一片空白 ：（     FB.api（ '/我'）; //需要OAUTH

但结果为0。 提前谢谢。
