php获取抖音无水印视频代码，新人求助
网上分享的获得抖音无水印视频地址的代码好像都过期了，抖音改版之后，无水印视频地址就保存在页面里的json数据中。用PC浏览器的F12也能直接看到无水印视频真实地址：
我以下代码已经获得到完整的json数据，就是不会取json数据里的值。
以下是代码全文，请大家帮忙，如何获得playAddr 下面的src的值？
第二楼是我获取的完整json数据。
<?php
//获取抖音无水印视频地址，网上能找到的代码貌似全部过期不能用了。
//只能 自己写
//抖音改版之后，视频无水印地址就隐藏在json数据中。
//任意一个抖音视频地址
$url="https://v.douyin.com/dvsqnKu/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_AUTOREFERER, true); //自动设置header中的referer信息
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //将数据保留到返回结果中 而非直接输出
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); //跟随重定向
$ret = curl_exec($ch);
curl_close($ch);
echo "**********在网页输出整个网站的原代码，方便自己查看**********************************";
echo "<br>";
$sourcecode=htmlentities($ret ,ENT_QUOTES,"UTF-8");
echo $sourcecode;
//抖音改版之后，视频无水印地址就隐藏在json数据中。利用正则表达式获取包含抖音无水印视频地址的json数据。
$mypreg='/json">.*?<\/script>/';
preg_match($mypreg,$ret,$matches);
$mydata=$matches[0];
//删除前面的json">共6个字符。取得最终的完整的json数据。
$jsondata= substr($mydata, 6);
echo "<br>";
echo "**********在网页上输出：提取出来的，未urlDecode解码的json数据**********************************";
echo "<br>";
print_r($jsondata);
//将json数据进行urlDecode解码，获得真实的json数据
$realjsondata=urldecode($jsondata);
echo "<br>";
echo "**********以下为urlDecode解码后的json数据**********************************";
echo "<br>";
echo "<pre>" . $realjsondata . "</pre>";
echo "<br>";
echo "**********将json数据转化为数组，但都是失败";
echo "<br>";
$arrobj=json_decode($realjsondata);
if (empty($arrobj)){
print_r("obj对象为空");
//error handle ,错误处理
$ret = json_last_error();
echo "<br>错误代码：".$ret; //查错误信息表，可知是语法错误
//错误是4
echo "<br>";
}
$arrdata=json_decode($realjsondata,true);
if (empty($arrdata)){
print_r("arr数组为空");
//error handle ,错误处理
$ret = json_last_error();
echo "<br>错误代码：".$ret; //查错误信息表，可知是语法错误
//错误是4
echo "<br>";
}
//以上两次转换都提示错误码4
// json_last_error错误msg对照表：
// 0 = JSON_ERROR_NONE
// 1 = JSON_ERROR_DEPTH
// 2 = JSON_ERROR_STATE_MISMATCH
// 3 = JSON_ERROR_CTRL_CHAR
// 4 = JSON_ERROR_SYNTAX
// 5 = JSON_ERROR_UTF8
?>
以下是完整的json数据，在我的程序里的变量是：$realjsondata

解析json 并无错误 gezhu 发表于 2021-10-16 09:02
抖音好像有防访问频率过快的问题，还得想办法解决一下那个滑块验证的问题。
那个暂时还没遇到，我就是想实现批量下载某一账号的全部视频。滑块验证有解决方案吗 不用啊，就正常的解析就行了，然后吧解析结果里面的链接换成1080 就是原始视频了，和网页的清晰度一样，你这样解析网页的不行的，访问几次就不行了，有验证码的
