推荐答案

我遇到了同样的问题，在任何opengraph测试工具以及他们自己的社交网站中，一切工作正常:facebook，twitter，ok，vk，但在whatsapp和;没有电报.

I have had the same problem, everything worked fine in any opengraph testing tool and in the social sites themself's: facebook, twitter, ok, vk but in whatsapp & telegram not.

因此，经过大量研究，问题出在我们的虚拟站点防火墙中，该防火墙通过许多逻辑来防止站点爬网，其中包括IP和User-Agent. whatsapp&电报ping站点以获取数据不会像社交站点那样将其扔到服务器上，而是通过移动运营商的动态IP进行，但是用户代理属于Messenger本身，并且位于我们自动生成的黑名单中.

So after a lot of research, the problem was in our virtual site firewall that protects from site crawling by many logics, a couple of them is IP and User-Agent. The whatsapp & telegram are pinging sites to fetch og data are not throw their servers like social sites, but through your mobile operator's dynamic IP, but the user-agent is of the messenger itself, and it was in our automatically generated blacklist.

通过包含以下内容的用户代理字符串检查是否不禁止其访问网站: WhatsApp/2.17.395 A 或 TelegramBot(例如TwitterBot)

Check if you don't ban access to your site by theirs user-agents string that contains: WhatsApp/2.17.395 A or TelegramBot (like TwitterBot)
