php中通过curl模拟登陆discuz论坛的实现代码

  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。

  

复制代码 代码如下:

  <?php

  $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('/<input\s*type="hidden"\s*name="formhash"\s*value="(.*?)"\s*\/>/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('/<input\s*type="hidden"\s*name="formhash"\s*id="formhash"\s*value="(.*?)"\s*\/>/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);

  ?>
