具体代码如下所示:
/* * 获得视频文件的缩略图和视频长度 * @date 2018-05-16 * @copyright */ //获得视频文件的总长度时间和创建时间 根据视频长度判断是否失效 public function getTime($url) { //获取视频重定向后的链接 $location = locationUrl($url); //获取视频Content-Length $responseHead = get_data($location); $list1 = explode("Content-Length: ", $responseHead); $list2 = explode("Connection", $list1[1]); $list = explode("x", $list2[0]); return $list[0]; } //获取视频重定向后的链接 function locationUrl($url){ $url_parts = @parse_url($url); if (!$url_parts) return false; if (!isset($url_parts['host'])) return false; if (!isset($url_parts['path'])) $url_parts['path'] = '/'; $sock = fsockopen($url_parts['host'], (isset($url_parts['port']) ? (int)$url_parts['port'] : '80'), $errno, $errstr, 30); if (!$sock) return false; $request = "HEAD " . $url_parts['path'] . (isset($url_parts['query']) ? '?'.$url_parts['query'] : '') . " HTTP/1.1\r\n"; $request .= 'Host: ' . $url_parts['host'] . "\r\n"; $request .= "Connection: Close\r\n\r\n"; fwrite($sock, $request); $response = ''; while(!feof($sock)) { $response .= fread($sock, 8192); } fclose($sock); if (preg_match('/^Location: (.+?)$/m', $response, $matches)){ if ( substr($matches[1], 0, 1) == "/" ){ return $url_parts['scheme'] . "://" . $url_parts['host'] . trim($matches[1]); } else{ return trim($matches[1]); } } else { return false; } } //审核视频 curl function get_data($url){ $oCurl = curl_init(); //模拟浏览器 $header[] = "deo.com"; $user_agent = "Mozilla/4.0 (Linux; Andro 6.0; Nexus 5 Build) AppleWeb/537.36 (KHTML, like Gecko)"; curl_setopt($oCurl, CURLOPT_URL, $url); curl_setopt($oCurl, CURLOPT_HTTPHEADER,$header); curl_setopt($oCurl, CURLOPT_HEADER, true); curl_setopt($oCurl, CURLOPT_NOBODY, true); curl_setopt($oCurl, CURLOPT_USERAGENT,$user_agent); curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1 ); // 不用 POST 方式请求, 意思就是通过 GET 请求 curl_setopt($oCurl, CURLOPT_POST, false); $sContent = curl_exec($oCurl); // 获得响应结果里的:头大小 $headerSize = curl_getinfo($oCurl, CURLINFO_HEADER_SIZE); // 根据头大小去获取头信息内容 $header = substr($sContent, 0, $headerSize); curl_close($oCurl); return $header; }
