这是在网站找到的代码。但是好像并不适用爱地狱资源网

/**

*/
add_action('wp_head', 'starfire',0);
if(!function_exists('starfire')){
  function starfire(){
    //新增判断,如果是原创文章才加入星火计划META申明
     global $wpdb;
     $post_id = ( null === $post_id ) ? get_the_ID() : $post_id;
     $copy = get_post_meta($post_id , 'author', true);
     if (is_singular() && empty($copy)) {
        date_default_timezone_set('PRC');
        echo '<meta property="og:type" content="article"/>
        <meta property="article:published_time" content="'.get_the_date('c').'"/>
        <meta property="og:release_date" content="'.get_the_date('c').'"/>

        <meta property="og:description" content="'.get_the_excerpt().'" />
        <meta property="og:image" content="'.get_mypost_thumbnail($post_id).'" />
        <meta itemprop="image" content="' . get_mypost_thumbnail($post_id) . '" />';
    }
  }
}
/**

function get_mypost_excerpt($post_ID,$len){
    if (!function_exists('utf8Substr')) {
        function utf8Substr($str, $from, $len) {
            return preg_replace('#^(?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'.$from.'}'.

    }
    if(!$post_content){
            $post = get_post($post_ID);
            $post_content = $post->post_content;
   }
    if ($post->post_excerpt) {
            $description  = $post->post_excerpt;
    } else {
        if(preg_match('/<p>(.*)<\/p>/iU',trim(strip_tags($post->post_content,"<p>")),$result)){

            $post_content = $post_content_r['0'];
        }

    }
}
/**

function get_mypost_thumbnail($post_ID){
    if (has_post_thumbnail()) {
            $timthumb_src = wp_get_attachment_image_src( get_post_thumbnail_id($post_ID), 'full' ); 
            $url = $timthumb_src[0];
    } else {
        if(!$post_content){
            $post = get_post($post_ID);
            $post_content = $post->post_content;
        }
        preg_match_all('|<img.*?src=[\'"](.*?)[\'"].*?>|i', do_shortcode($post_content), $matches);
        if( $matches && isset($matches[1]) && isset($matches[1][0]) ){       
            $url =  $matches[1][0];
        }else{
            $url =  '';
        }
    }
    return $url;
}

于是又找了找
找到了在header.php的代码如下

    <meta property="og:title" content="<?php the_title();?>" />  
    <meta property="og:site_name " content="<?php bloginfo('name'); ?>" />  
    <?php if (is_single()) : ?><meta property="og:type" content="acticle" />  
    <meta property="article:published_time" content="<?php echo get_the_date('c');?>"/>
    <meta property="og:release_date" content="<?php echo get_the_date('c'); ?> "/>
    <meta property="article:author" content="<?php echo bloginfo('name'); ?> " />';
    <meta property="og:author" content="'<?php echo bloginfo('name'); ?>" />';
    <meta property="article:published_first" content="<?php bloginfo('name'); ?>,<?php the_permalink();?>" />
    <meta property="og:description" content="<?php  echo get_the_excerpt(); ?>" />
    <meta property="og:url" content="<?php the_permalink();?>"/>  
    <?php if ( has_post_thumbnail()):   $meta_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'thumbnail'); ?>
<meta property="og:image" content="<?php echo $meta_image_url[0];?>" />  <?php endif; ?>  <?php else: ?>  
    <meta property="og:type" content="website" />  
<?php endif; ?>

修改其中的

<meta property="og:description" content="<?php echo get_post_excerpt(); ?>" />  

<meta property="og:description" content="<?php echo get_the_excerpt(); ?>" />
