detail.html template content

<video controls="controls" autoplay="autoplay">
<source type="video/ogg" src="xxx.com/goVideo.php?video=1" /><!--这样的地址他们就醉了吧，真实地主保护住了 而且每次进入详情页播放完了，重新进入detail链接方法中，才能播放 -->

detail.php control layer Content

// 先进入详情页
publicfunction detail(){
$_SESSION['token'] = md5("xxx"); //做一个token 用于失效方案
//进入到详情页
}

/** 
     +---------------------------------------------------------- 
     * 生成html video 播放地址 
     +---------------------------------------------------------- 
     * @access public 
     +---------------------------------------------------------- 
     */  
    public function goVideo()  
    {  
       $vid = (int)$_GET['videoId']; //数据库存放的资源id
       $data = $this->getInfo($vid); //通过vid 获取 数据库存放的真实资源地址
        if($_SESSION["token"]){  
            unset($_SESSION["token"]); //删除token，保证每次只能播放一次
         
        //页面直接输出视频
        $filePath=$data['URL']；
        ini_set('memory_limit', '512M');
        header("Pragma: public");
        header("Expires: 0");
        header("Content-Type: application/octet-stream"); //文件mime类型
        //header("Content-Disposition: attachment; filename=video11.mp4;" ); //文件名$filename
        //header("Content-Length: 83995");  //文件大小$fsize
        ob_clean();
        flush();
