我写了一个基于CURL的PHP5的类，功能比较简单，比较适合学习用。如果真要应用的话，那绝对推荐Snoopy 太强大了。虽然它不是在curl基础上的。转自 http://xiaowai.gentieba.com/node/33
<?php class my_curl { public function __construct() { ! extension_loaded ( 'curl' ) && exit ( 'CURL扩展未加载，程序终止运行' ); header ( 'Content-Type: text/html; charset=utf-8' ); } public function go($url, $vars = '') { $ch = curl_init (); $array [CURLOPT_URL] = $url; $array [CURLOPT_HEADER] = false; $array [CURLOPT_RETURNTRANSFER] = true; $array [CURLOPT_FOLLOWLOCATION] = true; if (! empty ( $vars )) { $postfields = $this->render_postfields ( $vars ); //生成urlcode的url $array [CURLOPT_POST] = true; $array [CURLOPT_POSTFIELDS] = $postfields; } //判断是否有cookie,有的话直接使用 if ($_COOKIE ['cookie_jar'] || is_file ( $_COOKIE ['cookie_jar'] )) { $array [CURLOPT_COOKIEFILE] = $_COOKIE ['cookie_jar']; //这里判断cookie } else { $cookie_jar = tempnam ( '/tmp', 'cookie' ); //产生一个cookie文件 $array [CURLOPT_COOKIEJAR] = $cookie_jar; //写入cookie信息 setcookie ( 'cookie_jar', $cookie_jar ); //保存cookie路径 } curl_setopt_array ( $ch, $array ); //传入curl参数 $content = curl_exec ( $ch ); //执行 curl_close ( $ch );//关闭 return $content; //返回 } protected function render_postfields($vars) { foreach ( $vars as $key => $values ) { $postdata .= urlencode ( $key ) . "=" . urlencode ( $values ) . "&"; } return $postdata; } } ?>
使用方法
<?php if($_POST['email']&&$_POST['password']){ include 'curl_class.php'; $curl = new my_curl (); $vars ['email'] = $_POST['email']; $vars ['password'] = $_POST['password']; //$vars ['done'] = '/'; //$vars ['submit'] = '登 录'; echo $curl->go ( 'http://www.renren.com/PLogin.do', $vars ); }else{ ?> <html> <form action="" class="login-form" id="loginForm" method="post"> <input type="text" id="email" name="email"/> <input type="text" id="password" name="password"/> <input type="submit" tabindex="4" value="登录" class="input-submit" id="login"> </form> </html> <?php }?>
