Facebook删除帖子

Question

我正在使用Faceebok JS API，函数FB.ui发布。但每当我点击发布时没有文字，帖子会在我发布后几秒钟删除。当我输入文本时，它不会被删除。我的职责是：

function postar(){
          FB.ui(
  {
    method: 'feed',
    name: 'x',
    link: 'x',
    picture: 'x',
    caption: 'x',
    description: 'x'
  },
  function(response) {
    if (response && response.post_id) {
      console.log('Post was published.');
    } else {
      console.log('Post was not published.');
    }
  }
); 

有谁知道我该如何解决？

提前致谢
