php curl封装类使用例子

php curl封装类使用例子

 　　使用函数之前我们要需要把php curl模块打开(libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)

　　开启php curl函数库的步骤

　　1).去掉windows/php.ini 文件里;extension=php_curl.dll前面的; /*用 echo phpinfo();查看php.ini的路径*/

　　2).把php5/libeay32.dll，ssleay32.dll复制到系统目录windows/下

　　3).重启apache

　　php curl

代码如下

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); cul处理类 class Curl { public $cookieFile; public $timeout = 160; Public function __construct($dir){ $this->cookieFile = $this->getTemporaryCookieFileName($dir); } /** * 设置CURL参数并发送请求，获取响应内容 * @access private * @param $curlOptions array curl设置参数数组 * @return string|false 访问成功，按字符串形式返回获取的信息；否则返回false */ public function getResponseText($curlOptions) { /* 设置CURLOPT_RETURNTRANSFER为true */ if(!isset($curlOptions[CURLOPT_RETURNTRANSFER]) || $curlOptions[CURLOPT_RETURNTRANSFER] == false) { $curlOptions[CURLOPT_RETURNTRANSFER] = true; } /* 初始化curl模块 */ $curl = curl_init(); /* 设置curl选项 */ curl_setopt_array($curl, $curlOptions); /* 发送请求并获取响应信息 */ $responseText = ''; try { $responseText = curl_exec($curl); if(($errno = curl_errno($curl)) != CURLM_OK) { $errmsg = curl_error($curl); throw new Exception($errmsg, $errno); } } catch (Exception $e) { //exceptionDisposeFunction($e); //print_r($e); $responseText = false; } /* 关闭curl模块 */ curl_close($curl); /* 返回结果 */ return $responseText; } /** * 将Unicode字符串(u0000)转化为utf-8字符串，工具函数 * @access private * @static * @param $string string Unicode字符串 * @return string utf-8字符串 */ public function unicodeToUtf8($string) { $string = str_replace('u', '', strtolower($string)); $length = strlen($string) / 4; $stringResult = ''; for($i = 0; $i $charUnicodeHex = substr($string, $i * 4, 4); $unicodeCode = hexdec($charUnicodeHex); $utf8Code = ''; if($unicodeCode $utf8Code = chr($unicodeCode); } else if($unicodeCode $utf8Code .= chr(192 + (($unicodeCode - ($unicodeCode % 64)) / 64)); $utf8Code .= chr(128 + ($unicodeCode % 64)); } else { $utf8Code .= chr(224 + (($unicodeCode - ($unicodeCode % 4096)) / 4096)); $utf8Code .= chr(128 + ((($unicodeCode % 4096) - ($unicodeCode % 64)) / 64)); $utf8Code .= chr(128 + ($unicodeCode % 64)); } $stringResult .= $utf8Code; } return $stringResult; } private function getTemporaryCookieFileName($dir='.') { return (str_replace("", '/', tempnam($dir, 'tmp'))); } }
