Answer 1

如果你从调试器的输出，你会看到，该网站被重定向到一个无效的网址：

Fetched URL: https://jelvix.com/blog/how-to-create-and-manage-a-successful-company-jelvix-story 
Canonical URL: https://jelvix.com/404 

抓取工具将尝试从最终网址https://jelvix.com/404获取og标记。 您需要确保最终到达网址包含抓取工具能够获取正确值的元标记。

目前看起来您的网站正在将Facebook抓取工具重定向到/ 404。

curl -A 'facebookexternalhit/1.1' https://jelvix.com/blog/how-to-create-and-manage-a-successful-company-jelvix-story 
Found. Redirecting to /404
