//随机IP
function Rand_IP(){

 $ip3id= round(rand(600000, 2550000) / 10000);
 $ip4id= round(rand(600000, 2550000) / 10000);
 //下面是第二种方法，在以下数据中随机抽取
 $arr_1 = array("218","218","66","66","218","218","60","60","202","204","66","66","66","59","61","60","222","221","66","59","60","60","66","218","218","62","63","64","66","66","122","211");
 $randarr= mt_rand(0,count($arr_1)-1);
 $ip1id = $arr_1[$randarr];
 return $ip1id.".".$ip2id.".".$ip3id.".".$ip4id;
}
//抓取页面内容
function Curl($url){
  $ch2 = curl_init();
  $user_agent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.66 Safari/537.36";//模拟windows用户正常访问
  curl_setopt($ch2, CURLOPT_URL, $url);
  curl_setopt($ch2, CURLOPT_TIMEOUT, 10);
  curl_setopt($ch2, CURLOPT_HTTPHEADER, array(&#39;X-FORWARDED-FOR:&#39;.Rand_IP(), &#39;CLIENT-IP:&#39;.Rand_IP()));
//追踪返回302状态码，继续抓取
  curl_setopt($ch2, CURLOPT_HEADER, true); 
  curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true); 
  curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true);
  curl_setopt($ch2, CURLOPT_NOBODY, false);
  curl_setopt($ch2, CURLOPT_REFERER, &#39;http://www.baidu.com/&#39;);//模拟来路
  curl_setopt($ch2, CURLOPT_USERAGENT, $user_agent);
  $temp = curl_exec($ch2);
  curl_close($ch2);
  return $temp;
