服务器主要通过User-Agent识别客户端是何种设备
User-Agent是Http协议中的一部分，属于头域的组成部分。基本格式为： 浏览器标识 (操作系统标识; 加密等级标识; 浏览器语言) 渲染引擎标识 版本信息。
具体方法如下：
/**
* curl获取数据
* @param $url
* @return mixed
*/
function get_Url($url) {
$ifpost = 0;
$datafields = '';
$cookiefile = '';
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$v = false;
//构造随机ip
$ip_long = array(
array('607649792', '608174079'), //36.56.0.0-36.63.255.255
array('1038614528', '1039007743'), //61.232.0.0-61.237.255.255
array('1783627776', '1784676351'), //106.80.0.0-106.95.255.255
array('2035023872', '2035154943'), //121.76.0.0-121.77.255.255
array('2078801920', '2079064063'), //123.232.0.0-123.235.255.255
array('-1950089216', '-1948778497'), //139.196.0.0-139.215.255.255
array('-1425539072', '-1425014785'), //171.8.0.0-171.15.255.255
array('-1236271104', '-1235419137'), //182.80.0.0-182.92.255.255
array('-770113536', '-768606209'), //210.25.0.0-210.47.255.255
array('-569376768', '-564133889'), //222.16.0.0-222.95.255.255
);
$rand_key = mt_rand(0, 9);
$ip= long2ip(mt_rand($ip_long[$rand_key][0], $ip_long[$rand_key][1]));
//模拟http请求header头
$header = array("Connection: Keep-Alive","Accept: text/html, application/xhtml+xml, */*", "Pragma: no-cache", "Accept-Language: zh-Hans-CN,zh-Hans;q=0.8,en-US;q=0.5,en;q=0.3","User-Agent: .$user_agent",'CLIENT-IP:'.$ip,'X-FORWARDED-FOR:'.$ip);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, $v);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
$ifpost && curl_setopt($ch, CURLOPT_POST, $ifpost);
$ifpost && curl_setopt($ch, CURLOPT_POSTFIELDS, $datafields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$cookiefile && curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
$cookiefile && curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);
curl_setopt($ch,CURLOPT_TIMEOUT,60); //允许执行的最长秒数
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$ok = curl_exec($ch);
curl_close($ch);
unset($ch);
return $ok;
}使用：
public function getUserVideoList() {
$url = 'xxxxx'; // get请求
$json = get_url($url);
// $data = json_decode($json,true); // json转为数组
}
