Wordpress 嵌入 Gist代码

gist.php

function wp_iframe_handler_gist( $matches, $attr, $url, $rawattr ) {
    $iframe = '<iframe width="100%" height="300" src="https://gist.github.com/'. esc_attr($matches[1]) .'/'. esc_attr($matches[2]) . '.pibb" frameborder=0 ></iframe>';
    return apply_filters( 'iframe_gist', $iframe, $matches, $attr, $url, $rawattr );
}
wp_embed_register_handler( 'gist_iframe', '#https://gist.github.com/(.*?)/([\w]+)#i', 'wp_iframe_handler_gist' )

https://gist.github.com/(.*?)/([\d]+)#i 需改成 #https://gist.github.com/(.*?)/([\w]+)#i
