用PHP如何实现解析抖音无水印视频

清华大佬耗费三个月吐血整理的几百G的资源，免费分享！....>>>

很多时候你在douyin里看到了一个短视频，想复制下来自己编辑文字来发布，可是视频里的水印却是原者的。这个时候你想把水印去掉，你要如何做呢？这里提供PHP实现去除水印的主要方法，其实很简单。

<?php
header("Content-Type: text/json;charset=utf-8");
$url=$_GET["url"];
$UserAgent = 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; .NET CLR 3.5.21022; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_ENCODING, '');
curl_setopt($curl, CURLOPT_USERAGENT, $UserAgent);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
$data = curl_exec($curl);
curl_close($curl); //获取 preg_match('/<p class="desc">(?<desc>[^<>]*)<\/p>/i', $data, $name);
preg_match('/playAddr: "(?<url>[^"]+)"/i', $data, $url); //正则匹配 if (empty($url['url'])) {
    echo '请输入正确网址，格式为：https://xxx.com/douyin.php?url=视频地址';
}else{
    $array = ['name' => $name['desc'],'url' => $url['url'],];
    $json = json_encode($array,JSON_UNESCAPED_SLASHES|JSON_UNESCAPED_UNICODE|JSON_PRETTY_PRINT);
    echo $json;
} 

效果截图如下，url就是原视频链接，不带水印。
