原理如下:

 0, 'msg' => '请输入正确视频网址，格式为：douyin.php?url=视频地址']);
}else{
    $data = GetUrl($url);
    //获取
    preg_match('/playAddr: "(?[^"]+)"/i', $data, $url);
    preg_match('/
(?[^<>]*)<\/p>/i', $data, $name);
    $name = $name['desc'];
    $url = $url['url'];
    if(empty($url))
    {
        echo json_encode(['code' => 0, 'msg' => '解析错误']);
        exit;
    }
     
    preg_match('/s_vid=(.*?)&/', $url, $id);
    $url = 'https://aweme.snssdk.com/aweme/v1/play/?s_vid=' . $id[1] . '&line=0';
    $data_new = GetVideos($url);
    preg_match('//', $data_new, $link);
     
    if (empty($link[1])) {
        echo json_encode(['code' => 0, 'msg' => '解析错误']);
        exit;
    }
     
    $link = 'http://' . $link[1];
    echo json_encode(['code' => 1, 'name' => $name, 'url' => $link]);
}
