php的curl封装类用法实例

本文实例讲述了两个php curl封装类的用法实例，这两个函数可以让我们非常的方便的使用php curl相关函数。分享给大家供大家参考。具体如下：

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

代码如下：

<?php

include_once('curl.class.php');

$aa =new Curl('');

 $curlOptions = array(

 CURLOPT_URL => "http://www.xx.com/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=%E6%8A%95%E7%A5%A8', //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：

<?php

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')));

}

}

 
例子2

<?php

//curl类

class Curl

    function Curl(){

        return true;

    }

     

    function execute($method, $url, $fields='', $userAgent='', $httpHeaders='', $username='', $password=''){

        curl_setopt($ch, CURLOPT_HEADER, false);

        //

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    }

     

    function post($url, $fields, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){

        if(!is_resource($ch)){

            return false;

?>

用法

GET用法：

$curl = new Curl();

$curl->get('https://3water.com/');

POST用法：

$curl = new Curl();

$curl->get('https://3water.com/', 'p=1&time=0′);

希望本文所述对大家的PHP程序设计有所帮助。
