为什么Facebook的短绒是不是看到我的OG：图像

Question

我有此链接：

当我去Facebook linter

但是，当我看到我的页面的源代码，我有：

<title> Kendozone - Registro de competidores </title> <meta property="og:title" content="Registro de competidores"/> <meta name=" twitter:title" content="Registro de competidores"/>  <meta name="description" content="Registrate en el torneo 1a Copa Hiroshi Kamio"/> <meta property="og:description" content="Registrate en el torneo 1a Copa Hiroshi Kamio" /> <meta name="twitter:card" content="summary" /> <meta name="twitter:description" content="Registrate en el torneo 1a Copa Hiroshi Kamio" />  
    <meta property="og:locale" content="es"/> 
    <meta property="og:type" content="website"/> 
    <meta property="og:image" content="https://kendozone.com/wp-content/uploads/2016/04/home.jpg" /> 
    <meta property="og:image:secure_url" content="https://kendozone.com/wp-content/uploads/2016/04/home.jpg" /> 
    <meta name="twitter:image" content="https://kendozone.com/wp-content/uploads/2016/04/home.jpg" /> 
    <meta property="og:url" content="https://my.kendozone.com/tournaments/1a-copa-hiroshi-kamio/register"/> 
    <meta property="og:site_name" content="Kendozone"/> 

怎么回事？

Answer 1

我在该URL重定向到https://my.kendozone.com/login。所以，我想像一下，Facebook。 Facebook将会看到与点击该URL的匿名用户相同的OG代码。

有可能（and recommended by Facebook）您向Facebook抓取工具的用户代理提供了一个单独的页面，该页面带有正确的OG标签。请注意，非Facebook用户可以欺骗此用户代理，所以此页面不应泄漏任何类型的秘密细节。
