下面整理两个php curl封装类使用例子,这两个函数可以让我们非常的方便的使用php curl相关函数,下面我们一起来看看吧.
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
php curl,代码如下:
- <?php
- include_once('curl.class.php');
- $aa =new Curl('');
- $curlOptions = array(
- CURLOPT_URL => "http://ww.ww.ww/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,代码如下:
- <?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($dir, 'tmp')));
- }
- }
- ?>
例子2,代码如下:
- <?php
- //curl类
- class Curl
- {
- function Curl(){
- return true;
- }
- function execute($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;
- }
- }
- ?>
用法,GET用法:
$curl = new Curl();$curl->get(‘http://www.phpfensi.com/’);
POST用法:
$curl = new Curl();$curl->get(‘http://www.phpfensi.com/’,‘p=1&time=0′);
