php curl封装类使用例子

include_once('curl.class.php');
$aa =new Curl('');
 $curlOptions = array(
 CURLOPT_URL => "http://ww.ww.ww/addTicket.jsp", //访问URL
 CURLOPT_RETURNTRANSFER => true, //获取结果作为字符串返回
 CURLOPT_REFERER => "ww.ww.ww/zw2",
 CURLOPT_HTTPHEADER => array('X-FORWARDED-FOR:139.197.14.19', 'CLIENT-IP:127.0.0.1','Proxy-Client-IP:139.197.14.19','WL-Proxy-Client-IP:139.197.14.19' ),
 CURLOPT_HEADER => 1, //获取返回头信息

 //CURLOPT_SSL_VERIFYPEER => false, //支持SSL加密
 CURLOPT_POST => true, //发送时带有POST参数
 CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //请求的POST参数字符串
 CURLOPT_TIMEOUT => $aa->timeout //等待响应的时间
 );
 echo $aa->getResponseText($curlOptions);

用法

GET用法：

$curl = new Curl();
$curl->get(‘http://www.111cn.net/’);

POST用法

$curl = new Curl();
$curl->get(‘http://www.111cn.net/’, ‘p=1&time=0′);
