Facebook图片缓存适用于元标记，因此我获得了元标记 所以我试图附加到头部它已完成但图像缓存不起作用..
以下是代码：
$("head").append('<meta property="og:type" content="article" />
<meta property="og:title" content="When Great Minds Don’t Think Alike" />
<meta property="og:description" content="How much does culture influence creative thinking?" />
<meta property="og:image"content="'+item.snippet.thumbnails.high.url+'"/>');
