【WordPress 插件】Begin视频播放插件Smartideo支持B站BV号

B站（bilibili）近期调整视频链接ID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，用户已在插件作者网站反映，作者并没有回应。

打开Smartideo插件smartideo.php文件，在大约87行：

array($this, 'smartideo_embed_handler_bilibili') );

下面添加：

wp_embed_register_handler( 'smartvideo_bilibili_bv',
	'#https?://www\.bilibili\.com/video/BV(?:(?<video_id1>[a-z0-9_=\-]+)/(?:index_|\#page=)(?<video_id2>[a-z0-9_=\-]+)|(?<video_id>[a-z0-9_=\-]+))#i',
	array($this, 'smartvideo_embed_handler_bilibili_bv') );

接下来在大约195行找到：

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

在其下面“}”大括号下面添加：

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 );
}

之后直接在文章中添加B站视频地址：

https://www.bilibili.com/video/BV1WW411b7NQ

插件貌似不支原来的av地址

https://www.bilibili.com/video/av17792443

再接着修改一下吧，将：

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 );
}

直接改为：

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 );
}

补充：防止选择清晰度或者点击图标时跳转到B站。

打开Smartideo插件smartideo.php文件找到：

<iframe src="' . $url . '" width="100%" height="100%" frameborder="0" allowfullscreen="true"></iframe>

修改为：

<iframe src="' . $url . '" width="100%" height="100%" frameborder="0" allowfullscreen="true"  sandbox="allow-top-navigation allow-same-origin allow-forms allow-scripts"></iframe>

修改后会影响其它视频正常加载,修改后同时兼容av和BV号，演示效果：
