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=投票', //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 < $length; $i ) {
$charUnicodeHex = substr($string, $i * 4, 4);
$unicodeCode = hexdec($charUnicodeHex);
$utf8Code = '';
if($unicodeCode < 128) {
$utf8Code = chr($unicodeCode);
} else if($unicodeCode < 2048) {
$utf8Code .= chr(192 (($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')));
}
}

 代码如下

方便

获取帮助:

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

POST 处理

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