有什么方法可以设置在我在 Facebook 上分享我的网站时显示的默认图片?我注意到 Facebook 通常会从网站上获取第一张图片用作缩略图.

Is there any way to set a default image that appears when I share my website on Facebook? I've noticed that Facebook usually fetches the first image from the site to use as a thumbnail.

推荐答案

需要设置facebook图片元标签:

You need to set the facebook image meta tag:

<meta property="og:image" content="http://example.com/logo.jpg">
<meta property="og:image:type" content="image/png">
<meta property="og:image:width" content="1024">
<meta property="og:image:height" content="1024">
