php的curl封裝類用法實(shí)例

?使用函數(shù)之前我們要需要把php curl模塊打開(libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll)

開啟php curl函數(shù)庫的步驟

1).去掉windows/php.ini 文件里;extension=php_curl.dll前面的; /*用 echo phpinfo();查看php.ini的路徑*/
2).把php5/libeay32.dll，ssleay32.dll復(fù)制到系統(tǒng)目錄windows/下
3).重啟apache

代碼如下：

?

代碼如下:

include_once('curl.class.php');
$aa =new Curl('');
?$curlOptions = array(
?CURLOPT_URL => "http://www.xx.com/addTicket.jsp", //訪問URL
?CURLOPT_RETURNTRANSFER => true, //獲取結(jié)果作為字符串返回
?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, //獲取返回頭信息
?//CURLOPT_SSL_VERIFYPEER => false, //支持SSL加密
?CURLOPT_POST => true, //發(fā)送時(shí)帶有POST參數(shù)
?CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //請(qǐng)求的POST參數(shù)字符串
?CURLOPT_TIMEOUT => $aa->timeout //等待響應(yīng)的時(shí)間
?);
?echo $aa->getResponseText($curlOptions);

cul處理類：

代碼如下:

class Curl
{
public $cookieFile;
public $timeout = 160;
Public function __construct($dir){
$this->cookieFile = $this->getTemporaryCookieFileName($dir);
}
/**
* 設(shè)置CURL參數(shù)并發(fā)送請(qǐng)求，獲取響應(yīng)內(nèi)容
* @access private
* @param $curlOptions array curl設(shè)置參數(shù)數(shù)組
* @return string|false 訪問成功，按字符串形式返回獲取的信息；否則返回false
*/
public function getResponseText($curlOptions) {
/* 設(shè)置CURLOPT_RETURNTRANSFER為true */
if(!isset($curlOptions[CURLOPT_RETURNTRANSFER]) || $curlOptions[CURLOPT_RETURNTRANSFER] == false) {
$curlOptions[CURLOPT_RETURNTRANSFER] = true;
}
/* 初始化curl模塊 */
$curl = curl_init();
/* 設(shè)置curl選項(xiàng) */
curl_setopt_array($curl, $curlOptions);
/* 發(fā)送請(qǐng)求并獲取響應(yīng)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);
$responseText = false;
}
/* 關(guān)閉curl模塊 */
curl_close($curl);
/* 返回結(jié)果 */
return $responseText;
}
/**
* 將Unicode字符串(u0000)轉(zhuǎn)化為utf-8字符串，工具函數(shù)
* @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')));
}
}

用法

GET用法：

代碼如下:

$curl = new Curl();
$curl->get('http://www.jb51.net/');

POST用法：

復(fù)制代碼 代碼如下:

$curl = new Curl();
$curl->get('http://www.jb51.net/', 'p=1&time=0′);
