php的curl封裝類用法實例

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

開啟php curl函數庫的步驟

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

代碼如下：

 

代碼如下: <?php
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, //發送時帶有POST參數
 CURLOPT_POSTFIELDS => 'ids=897&Submit=%E6%8A%95%E7%A5%A8', //請求的POST參數字符串
 CURLOPT_TIMEOUT => $aa->timeout //等待響應的時間
 );
 echo $aa->getResponseText($curlOptions);

cul處理類：

代碼如下: <?php
class Curl
{
public $cookieFile;
public $timeout = 160;
Public function __construct($dir){
$this->cookieFile = $this->getTemporaryCookieFileName($dir);
}
/**
* 設置CURL參數並發送請求，獲取響應內容
* @access private
* @param $curlOptions array curl設置參數數組
* @return string|false 訪問成功，按字符串形式返回獲取的信息；否則返回false
*/
public function getResponseText($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 */
$curl = curl_init();
/* 設置curl選項 */
curl_setopt_array($curl, $curlOptions);
/* 發送請求並獲取響應信息 */
$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);
$responseText = false;
}
/* 關閉curl模塊 */
curl_close($curl);
/* 返回結果 */
return $responseText;
}
/**
* 將Unicode字符串(u0000)轉化為utf-8字符串，工具函數
* @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')));
}
}

 
例子2

 

 

代碼如下: <?php
//curl類
class Curl
{
    function Curl(){
        return true;
    }
    
    function execute($method, $url, $fields='', $userAgent='', $httpHeaders='', $username='', $password=''){
        $ch = Curl::create();
        if(false === $ch){
            return false;
        }
        if(is_string($url) && strlen($url)){
            $ret = curl_setopt($ch, CURLOPT_URL, $url);
        }else{
            return false;
        }
        //是否顯示頭部信息
        curl_setopt($ch, CURLOPT_HEADER, false);
        //
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        if($username != ''){
            curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);
        }
        $method = strtolower($method);
        if('post' == $method){
            curl_setopt($ch, CURLOPT_POST, true);
            if(is_array($fields)){
                $sets = array();
                foreach ($fields AS $key => $val){
                    $sets[] = $key . '=' . urlencode($val);
                }
                $fields = implode('&',$sets);
            }
            curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
        }else if('put' == $method){
            curl_setopt($ch, CURLOPT_PUT, true);
        }
        //curl_setopt($ch, CURLOPT_PROGRESS, true);
        //curl_setopt($ch, CURLOPT_VERBOSE, true);
        //curl_setopt($ch, CURLOPT_MUTE, false);
        curl_setopt($ch, CURLOPT_TIMEOUT, 10);//設置curl超時秒數
        if(strlen($userAgent)){
            curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
        }
        if(is_array($httpHeaders)){
            curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders);
