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:

  

复制代码 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:

  

复制代码 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

  

复制代码 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:

  

复制代码 代码如下:
$curl = new Curl();

  $curl->get('http://www.glzy8.com/');

  POST用法:

  

复制代码 代码如下:
$curl = new Curl();

  $curl->get('http://www.glzy8.com/', 'p=1&time=0′);
