php - 在使用 PHP Simple HTML DOM Parser 之前登录到 ASP 网站

Question

我正在使用“PHP Simple HTML DOM Parser”来解析来自游戏 ASP 网站的数据。我需要抓取的数据仅对注册用户可见，所以我需要一些东西让我在开始使用它之前登录到站点。有人可以建议我一个脚本或可以做到这一点的东西吗？提前非常感谢！

First, you should post with:

<?php
function do_post_request($url, $data, $optional_headers = null)
{
  $params = array('http' => array(
              'method' => 'POST',
              'content' => $data
            ));
  if ($optional_headers !== null) {
    $params['http']['header'] = $optional_headers;
  }
  $ctx = stream_context_create($params);
  $fp = @fopen($url, 'rb', false, $ctx);
  if (!$fp) {
    throw new Exception("Problem with $url, $php_errormsg");
  }
  $response = @stream_get_contents($fp);
  if ($response === false) {
    throw new Exception("Problem reading data from $url, $php_errormsg");
  }
  return $response;
}

That should be able to send a post request. After that, you should be able to grab what you need.
