是否有内置功能来查看URLI是否兼容？

Question

我希望能够使用一个URL，看看该域是否是WordPress支持的域之一，可以通过OEMBED添加嵌入。是否有内置函数可以在WordPress中执行此操作，或者我需要创建自己的功能？

示例：如果我从视频网站上有一个URL，我希望能够检查URL，并能够判断WordPress支持该域是否支持将其用作视频。

wp-includes/class-oembed.php 有公共变量 $providers. 。因此，您可以构建一个小功能以获取所有功能：

function list_oembed_providers( $print = TRUE )
{
    require_once( ABSPATH . WPINC . '/class-oembed.php' );
    $oembed = _wp_oembed_get_object();

    $print and print '<pre>' . htmlspecialchars( var_export( $oembed->providers, TRUE ) ) . '</pre>';
    return $oembed->providers;
}

如果您调用此功能…

list_oembed_providers();

…您进入WordPress 3.1.1：
