前言说明

最近一段时间在外旅游，所以更新也是停滞了很久，今天抽空给大家更新一下。前段时间一直在研究短视频去水印接口，也更新了短视频去水印小程序V1.1.1版本?与?短视频去水印接口贩卖机，这两套源码都是需要一个接口，鉴于此我就自己开始研究去水印接口了。

所需工具

这里我以快手为例

1、快手APP

2、电脑

3、浏览器

教程开始

1、获取链接，去快手获取视频的分享链接,这一点相信大家都会。

2、使用Edge浏览器打开我们获取的视频链接：

 https://v.kuaishou.com/aU7PCz

(当然你也可以选择其他浏览器，我习惯使用Edge是因为他的开发者工具是中文对小白友好方便进行演示)
我们看到地址栏发生了变化说明这个链接进行了一次跳转此时的链接变成了

https://www.kuaishou.com/short-video/3xte53diytuu28g?fid=433527594&cc=share_copylink&followRefer=151&shareMethod=TOKEN&docId=10&kpn=KUAISHOU&subBiz=BROWSE_SLIDE_PHOTO&photoId=3xte53diytuu28g&shareId=16414084109664&shareToken=X1KCROiOhf2y1NY&shareResourceType=PHOTO_SELF&userId=3xe6mvxkxk8hrvc&shareType=2&et=1_a%2F2003086636508528529_p0&shareMode=APP&originShareId=16414084109664&appType=21&shareObjectId=5191243054590022521&shareUrlOpened=0&timestamp=1630310980813&utm_source=app_share&utm_medium=app_share&utm_campaign=app_share&location=app_share

3、开始抓包，我们按下键盘的F12出开发者工具网络（network）选择保留日志（preserve log ）然后按F5刷新页面我们会抓到网页所有发送的请求。

4、按下键盘ctrl+F 搜索标题，?我们会在响应中看到一大段的乱码。

5、点击乱码ctrl+a全选并复制乱码，?你会发现出现一堆JSON(一般官方接口大都是返回JSON格式) 大家可以去 https://www.bejson.com/jsonviewernew 格式化一下方便查看。

6、格式化之后我们可以按下键盘ctrl+F搜索 mp4?这样我们就得到了没有水印的视频链接。

去水印链接如下：

写成接口

1、新建“index.php”文件，复制下面请求代码

<?php
require 'qsy.php';
echo getUrl();
    function getUrl()
{
        $data = \Ludeqi::qsy($_GET['url']);
    return  $data;
    }

2、在同目录新建“qsy.php”文件，复制去水印算法代码

<?php
class Ludeqi {
  
    static public function qsy($url) {
    
        preg_match('/([\w-]+\.)+\w+(\:\d{2,6})?/', $url, $domain);
        switch ($domain[0]) {
            case '':
                return self::result(500, '请传入解析url参数，例：https://qsy.ludeqi.com/?url= https://v.kuaishou.com/aU7PCz/');
            break;
            case 'v.kuaishou.com':
                return self::kuaishou($url);
            break;
            default:
                return self::result(500, '抱歉，此url暂不支持！');
        }
    }
    static public function kuaishou($url) {
    
        $vurl = self::httpRequest($url, 'GET');
        preg_match('/(?<=video\/)\w*(?=\?fid)/', $vurl['location'], $matches);
        $str_qury1 = 'query visionVideoDetail($photoId: String, $type: String, $page: String, $webPageArea: String)';
        $str_qury2 = '(photoId: $photoId, type: $type, page: $page, webPageArea: $webPageArea)';
        $query = array("operationName" => "visionVideoDetail", "variables" => array('photoId' => $matches[0], "page" => "detail"), "query" => $str_qury1 . "{\n visionVideoDetail" . $str_qury2 . "{\n photo {\n id\n duration\n caption\n likeCount\n realLikeCount\n coverUrl\n photoUrl\n }\n}\n}\n",);
        $query = json_encode($query, 320);
        $headers = array('content-type: application/json', 'Referer:' . $vurl['location']);
        $result = self::httpRequest('https://video.kuaishou.com/graphql', 'POST', $query, $headers);
        if (isset($result['response']['data']['visionVideoDetail']['photo']['photoUrl'])) {
            return self::result(200, $result['response']['data']['visionVideoDetail']['photo']);
        } else {
            return self::result(500, '解析出错！');
        }
    }
  
    static public function httpRequest($url, $method = 'POST', $postfields = null, $headers = array()) {
    
        $method = strtoupper($method);
        $ci = curl_init();
        curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
        curl_setopt($ci, CURLOPT_CONNECTTIMEOUT, 60);
        curl_setopt($ci, CURLOPT_TIMEOUT, 30);
        curl_setopt($ci, CURLOPT_RETURNTRANSFER, 1);
        switch ($method) {
            case "POST":
                curl_setopt($ci, CURLOPT_POST, true);
                if (!empty($postfields)) {
                    $tmpdatastr = is_array($postfields) ? http_build_query($postfields) : $postfields;
                    curl_setopt($ci, CURLOPT_POSTFIELDS, $tmpdatastr);
                }
            break;
            default:
                curl_setopt($ci, CURLOPT_CUSTOMREQUEST, $method);
            break;
        }
        $ssl = preg_match('/^https:\/\//i', $url) ? TRUE : FALSE;
        curl_setopt($ci, CURLOPT_URL, $url);
        if ($ssl) {
            curl_setopt($ci, CURLOPT_SSL_VERIFYPEER, FALSE);
            curl_setopt($ci, CURLOPT_SSL_VERIFYHOST, FALSE);
        }
        curl_setopt($ci, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ci, CURLOPT_MAXREDIRS, 2);
        curl_setopt($ci, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ci, CURLINFO_HEADER_OUT, true);
        $response = json_decode(curl_exec($ci), true);
        $requestinfo = curl_getinfo($ci);
        $http_code = curl_getinfo($ci, CURLINFO_HTTP_CODE);
        $location = curl_getinfo($ci, CURLINFO_EFFECTIVE_URL);
        curl_close($ci);
        return array('location' => $location, 'response' => $response, 'requestinfo' => $requestinfo);
    }
  
    static public function result($errno = 0, $data = '') {
    
        header("Content-type: application/json;charset=utf-8");
        $errno = intval($errno);
        $result = array('code' => $errno, 'message' => $data);
        return json_encode($result, 320);
    }
}

3、将新建的两个文件：“index.php”、“qsy.php”上传至服务器。
