PHP代碼實(shí)現(xiàn)微視去水印

前言

1、一直在尋找微視去水印的方法乔宿，PHP的要不然過(guò)時(shí)了位迂，要不然就是java的，或者是Python的予颤。

2囤官、更過(guò)分的是有人提供api收費(fèi)接口打著，開源源碼的旗號(hào)蛤虐。

3、這里我就提供純粹的源碼思路肝陪，怎么啦驳庭！怎么啦

實(shí)現(xiàn)思路

1、參考博客：快手去水印解析獲取源標(biāo)題氯窍、作者饲常、頭像、封面圖以及源視頻下載地址

頁(yè)面分析

1狼讨、拿到一個(gè)快手分享頁(yè)面 http://kphbeijing.m.chenzhongtech.com/s/ARmv5BoW

然后我們獲取這個(gè)短視頻的文案標(biāo)題贝淤、視頻封面、視頻地址

獲取數(shù)據(jù)

       $headers = [
            'Connection' => 'keep-alive',
            'User-Agent'=>'Mozilla/5.0 (Linux; Android 5.0; SM-G900P Build/LRX21T) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Mobile Safari/537.36'
        ];
        $client = new Client(['headers'=>$headers]);

        //允許重定向獲取html
        $res = $client->request('GET', $url,['allow_redirects' => true]);
        $html = (string)$res->getBody();


        $Query = QueryList::getInstance();
        $json = $Query->html($html)->find('div[id=hide-pagedata]')->attr('data-pagedata');
        $video_data = json_decode($json,true);

獲取視頻詳細(xì)信息

     //獲取圖片id
        $photoId = $video_data['photoId'];
        $param = "client_key=56c3713c&photoIds=".$photoId;

        //計(jì)算sign
        $replace = str_replace("&", "",$param).'23caab00356c';
        $sig =md5($replace);

        $queryUrl = 'http://api.gifshow.com/rest/n/photo/info?'.$param."&sig=".$sig;

        //獲取url地址之后不能讓他重定向
        $res = $client->request('GET', $queryUrl,['allow_redirects' => false]);
        $body = (string)$res->getBody();
        $result = json_decode($body,true);

• 上面的代碼java版本的解釋一下政供，下面 new String(new byte[]{50, 51, 99, 97, 97, 98, 48, 48, 51, 53, 54, 99})明顯是一個(gè)固定的字符串java運(yùn)行結(jié)果23caab00356c播聪。然后是SecureUtil.md5().digestHex(replace)這句明顯就是SecureUtil.md5(replace)也就是phper看得懂的MD5加密：

 String replace = StrUtil.replace(param, "&", "") + new String(new byte[]{50, 51, 99, 97, 97, 98, 48, 48, 51, 53, 54, 99});
        String sig = SecureUtil.md5().digestHex(replace);

視頻封面朽基、視頻地址獲取

       $video_data = $result['photos'][0];
        $data['video_src']= $video_data['main_mv_url'];
        $data['video_cover'] = $video_data['thumbnail_url'];

文案標(biāo)題獲取

  $video_title = $video_data['caption'];
        $title =  explode('@',$video_title);
        for ($i=0;$i<count($title);$i++){
            $video_title = str_replace('@'.$title[$i],"",$video_title);
        }

        $title =  explode('#',$video_title);
        for ($i=0;$i<count($title);$i++){
            $video_title = str_replace('#'.$title[$i],"",$video_title);
        }

        $data['video_title'] = $video_title;

最后代碼總結(jié)

  public function kuaiShou($url){
        $headers = [
            'Connection' => 'keep-alive',
            'User-Agent'=>'Mozilla/5.0 (Linux; Android 5.0; SM-G900P Build/LRX21T) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Mobile Safari/537.36'
        ];
        $client = new Client(['headers'=>$headers]);

        //允許重定向獲取html
        $res = $client->request('GET', $url,['allow_redirects' => true]);
        $html = (string)$res->getBody();


        $Query = QueryList::getInstance();
        $json = $Query->html($html)->find('div[id=hide-pagedata]')->attr('data-pagedata');
        $video_data = json_decode($json,true);

        //獲取圖片id
        $photoId = $video_data['photoId'];
        $param = "client_key=56c3713c&photoIds=".$photoId;

        //計(jì)算sign
        $replace = str_replace("&", "",$param).'23caab00356c';
        $sig =md5($replace);

        $queryUrl = 'http://api.gifshow.com/rest/n/photo/info?'.$param."&sig=".$sig;

        //獲取url地址之后不能讓他重定向
        $res = $client->request('GET', $queryUrl,['allow_redirects' => false]);
        $body = (string)$res->getBody();
        $result = json_decode($body,true);

        //獲取到視頻相關(guān)數(shù)據(jù)
        $video_data = $result['photos'][0];
        $data['video_src']= $video_data['main_mv_url'];
        $data['video_cover'] = $video_data['thumbnail_url'];

        //獲取文案標(biāo)題
        $video_title = $video_data['caption'];
        $title =  explode('@',$video_title);
        for ($i=0;$i<count($title);$i++){
            $video_title = str_replace('@'.$title[$i],"",$video_title);
        }

        $title =  explode('#',$video_title);
        for ($i=0;$i<count($title);$i++){
            $video_title = str_replace('#'.$title[$i],"",$video_title);
        }

        $data['video_title'] = $video_title;
        return $data;
    }
