2020年3月23日 B站调整视频链接ID AV开头升级为BV开头，B站说是为了保护稿件信息安全，容纳更多投稿，维护UP主的权益。但升级后的链接造成WordPres视频播放插件Smartideo中的正则无法获取由数字和大小写字母组成的字符串，原来直接复制粘贴视频地址到文章中调用视频的方法失效，有用户已在插件作者网站反映，作者并没有回应，可能因各视频站更新升级频繁，Smartideo插件很多视频站点都已不支持，估计作者已放弃更新了，所以一下教大家AV和BV号共存播放视频！

支持播放:优酷、bilibili、ACfun、音悦台、网易视频、芒果TV、搜狐视频、土豆、56、腾讯视频、新浪视频、酷6、华数、乐视、YouTube 等网站。

1.首先打开Smartideo插件smartideo.php文件，在大约87行：

array($this, 'smartideo_embed_handler_bilibili') );

下面添加：

class="prettyprint">wp_embed_register_handler( 'smartvideo_bilibili_bv',
'#https?://www\.bilibili\.com/video/BV(?:(?[a-z0-9_=\-]+)/(?:index_|\#page=)(?[a-z0-9_=\-]+)|(?[a-z0-9_=\-]+))#i',
array($this, 'smartvideo_embed_handler_bilibili_bv') );

2.在大约195行代码：

return apply_filters( 'embed_bilibili', $embed, $matches, $attr, $url, $rawattr );

下面添加：

public function smartvideo_embed_handler_bilibili_bv( $matches, $attr, $url, $rawattr ) {
$matches['video_id'] = ($matches['video_id1'] == '') ? $matches['video_id'] : $matches['video_id1'];
$page = ($matches['video_id2'] > 1) ? $matches['video_id2'] : 1;
$cid = '';
$embed = $this->get_iframe("//player.bilibili.com/player.html?bvid={$matches['video_id']}&cid={$cid}&page={$page}", $url);
return apply_filters( 'embed_bilibili', $embed, $matches, $attr, $url, $rawattr );
}

这样可以加载播放视频了！(不过发现插件貌似也不支原来的av地址我们还需在修改一下！)

3.再接着修改一下吧，将代码：

public function smartideo_embed_handler_bilibili( $matches, $attr, $url, $rawattr ) {
$matches['video_id'] = ($matches['video_id1'] == '') ? $matches['video_id'] : $matches['video_id1'];
$page = ($matches['video_id2'] > 1) ? $matches['video_id2'] : 1;
$cid = '';
/*
try{
$request = new WP_Http();
$url = "https://api.bilibili.com/view?type=jsonp&appkey=8e9fc618fbd41e28&id=" . $matches['video_id'];
$data = (array)$request->request($url, array('timeout' => 3));
$json = json_decode($data['body'], true);
$cid = $json['cid'];

}catch(Exception $e){}
*/
if(wp_is_mobile() || $this->bilibili_pc_player == 1){
$embed = $this->get_iframe("//player.bilibili.com/player.html?aid={$matches['video_id']}&cid={$cid}&page={$page}", $url);
}else{
$embed = $this->get_link($url);
}
return apply_filters( 'embed_bilibili', $embed, $matches, $attr, $url, $rawattr );
}

替换成:

public function smartideo_embed_handler_bilibili( $matches, $attr, $url, $rawattr ) {
$matches['video_id'] = ($matches['video_id1'] == '') ? $matches['video_id'] : $matches['video_id1'];
$page = ($matches['video_id2'] > 1) ? $matches['video_id2'] : 1;
$cid = '';
$embed = $this->get_iframe("//player.bilibili.com/player.html?aid={$matches['video_id']}&cid={$cid}&page={$page}", $url);
return apply_filters( 'embed_bilibili', $embed, $matches, $attr, $url, $rawattr );
}

即可替换成BV号和BV号共存了！
