php的curl封裝類用法實例

編輯:關於PHP編程

     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')));
    }
    }

    用法

     

    GET用法:

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


    POST用法:

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