另外我调查了以下内容：
>通过HTTP而不是HTTPS提供内容,但通过HTTPS(例如https://stripe.com/no和https://www.facebook.com/)提供的许多其他网站都可以正常工作.
>作为公司页面发布.除了允许手动数据输入(作为临时解决方案),这没有任何区别.
>以不同的用户身份发布.没有任何区别.
>在网站上发布新内容,确保没有被LinkedIn缓存元数据.这也没有任何区别.
>在添加Open Graph元标记之前,这也是一个问题.
This might be a problem caused by LinkedIn,但是 – 考虑到这适用于其他网站 – 我开放的可能性是我做错了事情.
解决方法
The first time that LinkedIn’s crawlers visit a webpage when asked to share content via a URL,the data it finds (Open Graph values or our own analysis) will be cached for a period of approximately 7 days.
This means that if you subsequently change the article’s description,upload a new image,fix a typo in the title,etc.,you will not see the change represented during any subsequent attempts to share the page until the cache has expired and the crawler is forced to revisit the page to retrieve fresh content.
