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的curl真的是相当好用,网上一搜索相关文章都是关于curl模拟登陆的,很少人提供模拟discuz发贴的源码。
本文原文地址为:php curl模拟登录discuz并模拟发帖
例子:
- $discuz_url = 'http://127.0.0.1/discuz/';//论坛地址
- $login_url = $discuz_url .'logging.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'] = 'true';
- //用户名和密码,必须填写
- $post_fields['username'] = 'tianxin';
- $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($ch, CURLOPT_POST, 1);
- curl_setopt($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
- $send_url = $discuz_url."post.php?action=newthread&fid=2";
- $ch = curl_init($send_url);
- curl_setopt($ch, CURLOPT_HEADER, 0);
- curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
- curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
- $contents = curl_exec($ch);
- 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)) {
- $formhash = $matches[1];
- } else {
- die('Not found the forumhash.');
- }
- $post_data = array();
- //帖子标题
- $post_data['subject'] = 'test2';
- //帖子内容
- $post_data['message'] = 'test2';
- $post_data['topicsubmit'] = "yes";
- $post_data['extra'] = '';
- //帖子标签
- $post_data['tags'] = 'test';
- //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
- $post_data['formhash']=$formhash;
- $ch = curl_init($send_url);
- curl_setopt($ch, CURLOPT_REFERER, $send_url); //伪装REFERER
- curl_setopt($ch, CURLOPT_HEADER, 0);
- curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
- curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
- curl_setopt($ch, CURLOPT_POST, 1);
- curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
- $contents = curl_exec($ch);
- curl_close($ch);
- //清理cookie文件
- unlink($cookie_file);
- ?>
