php的curl封装类用法实例

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：

代码如下:

<&＃63;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);

代码如下:

<&＃63;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')));
}
}

代码如下:

<&＃63;php
//curl类
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, $url);
}else{
return false;
}
//是否显示头部信息
curl_setopt($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);//设置curl超时秒数
if(strlen($userAgent)){
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
}
if(is_array($httpHeaders)){
curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders);
}
$ret = curl_exec($ch);
if(curl_errno($ch)){
curl_close($ch);
return array(curl_error($ch), curl_errno($ch));
}else{
curl_close($ch);
if(!is_string($ret) || !strlen($ret)){
return false;
}
return $ret;
}
}

function post($url, $fields, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){
$ret = Curl::execute('POST', $url, $fields, $userAgent, $httpHeaders, $username, $password);
if(false === $ret){
return false;
}
if(is_array($ret)){
return false;
}
return $ret;
}

function get($url, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){
$ret = Curl::execute('GET', $url, '', $userAgent, $httpHeaders, $username, $password);
if(false === $ret){
return false;
}
if(is_array($ret)){
return false;
}
return $ret;
}

function create(){
$ch = null;
if(!function_exists('curl_init')){
return false;
}
$ch = curl_init();
if(!is_resource($ch)){
return false;
}
return $ch;
}
}

GET用法：

代码如下:

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

代码如下:

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