我在一个站点上的所有帖子中添加了开放式图形元数据，然而，当我尝试在Facebook上粘贴帖子链接时，图形元数据没有加载。

然后，当我插入URL时into the debugger / linter, 无论是在调试器中还是在Facebook上正常发布时（之前不起作用），它都可以工作。

这个问题似乎addressed in the past, in this Stack Overflow question. 然而，这个问题与Rails环境有关。

在这个问题上，应用程序无法同时处理多个http请求。通过在后台使用延迟响应（delayed\\u response）处理所有Facebook API请求，问题得以解决。

在运行Wordpress的PHP环境中，我可以用什么最简单的方式来完成这个或类似的任务，从而（希望）解决我的问题？

**我在这篇文章中没有包括一个示例链接，因为只要用户通过调试器运行它，它就会正常工作*
