libcurl同时也支持HTTPS认证、HTTP POST、HTTP PUT、 FTP 上传(这个也能通过PHP的FTP扩展完成)、HTTP 基于表单的上传、代理、cookies和用户名+密码的认证。

<?php $discuz_url = /;//论坛地址 $login_url = $discuz_url .login.php?action=login;//登录页地址$post_fields = array(); //以下两项不需要修改 $post_fields[loginfield] = username; $post_fields[loginsubmit] = rue; //用户名和密码，必须填写 $post_fields[username] = ianxin; $post_fields[password] = 111111; //安全提问 $post_fields[questionid] = 0; $post_fields[answer] = \; //@todo验证码 $post_fields[seccodeverify] = \; //获取表单FORMHASH $ch = curl_init($login_url); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $contents = curl_exec($ch); curl_close($ch); preg_match(//i’, $contents, $matches);

if(!empty($matches)) {

$formhash = $matches[1];

} else {

die(‘Not found the forumhash.’);

}

//POST数据，获取COOKIE,cookie文件放在网站的temp目录下

$cookie_file = tempnam(‘./temp’,’cookie’);

$ch = curl_init($login_url);

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);

curl_exec($ch);

curl_close($ch);

//取到了关键的cookie文件就可以带着cookie文件去模拟发帖,fid为论坛的栏目ID

$ch = curl_init($send_url);

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_close($ch);

//这里的hash码和登陆窗口的hash码的正则不太一样，这里的hidden多了一个id属性

preg_match(‘//i’, $contents, $matches);

if(!empty($matches)) {

$post_data = array();

//帖子标签

//帖子的hash码，这个非常关键！假如缺少这个hash码，discuz会警告你来路的页面不正确
