php的curl封裝類用法實(shí)例

字號(hào):


    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:
    <?php
    include_once('curl.class.php');
    $aa =new Curl('');
    $curlOptions = array(
    CURLOPT_URL => "", //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:

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