如何自动登录网站？

Question

我已经尝试在这个项目上工作了很长时间。我需要找到一种自动登录该网站的方法，以便人们每次都无需使用凭据即可查看日历信息。到目前为止，最好的方法是 php 中的代码使用 this YouTube video 中的 "curl" ；问题是登录系统不使用 "Post" 或 "Get"，它使用某种带有奇怪信息的 "xml"。

This is the login link

凭据：

Url -> http://www.cronospr.info/baikal/cal.php/calendars/test/default

用户 -> 测试

密码 -> 1234

任何信息将不胜感激！

代码：

<?php

//Upload a blank cookie.txt to the same directory as this file with a CHMOD/Permission to 777
function login($url,$data){
$fp = fopen("cookie.txt", "w");
fclose($fp);
$login = curl_init();
curl_setopt($login, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($login, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($login, CURLOPT_TIMEOUT, 40000);
curl_setopt($login, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($login, CURLOPT_URL, $url);
curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($login, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($login, CURLOPT_POST, TRUE);
curl_setopt($login, CURLOPT_POSTFIELDS, $data);
ob_start();
return curl_exec ($login);
ob_end_clean();
curl_close ($login);
unset($login);    
}                  

function grab_page($site){
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_URL, $site);
ob_start();
return curl_exec ($ch);
ob_end_clean();
curl_close ($ch);
}

function post_data($site,$data){
$datapost = curl_init();
    $headers = array("Expect:");
curl_setopt($datapost, CURLOPT_URL, $site);
    curl_setopt($datapost, CURLOPT_TIMEOUT, 40000);
curl_setopt($datapost, CURLOPT_HEADER, TRUE);
    curl_setopt($datapost, CURLOPT_HTTPHEADER, $headers);
curl_setopt($datapost, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($datapost, CURLOPT_POST, TRUE);
curl_setopt($datapost, CURLOPT_POSTFIELDS, $data);
    curl_setopt($datapost, CURLOPT_COOKIEFILE, "cookie.txt");
ob_start();
return curl_exec ($datapost);
ob_end_clean();
curl_close ($datapost);
unset($datapost);    
}

?>

<?php

echo grab_page("http://test:1234@www.cronospr.info/baikal/cal.php/calendars/test/default");

?>

似乎我在这里成功登录了，但这并不容易，它使用名为 "REPORT" 的自定义请求（无论是什么），并且使用 curl 发送自定义请求 body 很困难：p我也不知道如何构造 AUTHORIZATION header，我只是复制了 chrome 生成的 1。似乎也无法在此站点上使用 firefox 登录..

$ch=curl_init();
