无法获取使用 PHP cURL 登录的 .ASPXAUTH cookie 值

Question

我几乎 100% 确信我已经准备好互联网上包含关键字 asp login curly php .ASPXAUTH 的每一篇文章，但我一直无法找到解决方案。不过，我更像是一个代码黑客，而不是优雅的开发人员，所以我希望有人可以帮助我。

我有一个curl 脚本，可以登录其他两个网站，以便在登录后成功提交表单。但是，我最近尝试将此脚本的变体用于第三个网站。它可以在登录后返回第一页，但它会将任何进一步的 cURL 调用视为我尚未登录。我发现（我认为）这与未设置 .ASPXAUTH cookie 有关。我的 cURL 代码中确实有一个 cookiefile 和 cookiejar 设置，它成功捕获 .ASP.NET_SessionID，但不是 .ASPXAUTH cookie。

我注意到，当我观看“Live HTTP headers”时，我可以在标头中看到 .ASPXAUTH cookie 值，但我无法让我的 cURL 脚本轻松返回带有此 set-cookie 的标头。看来 cookie 是在登录后设置在 302 上的，而 cURL 没有正确处理这个问题。所以我关闭了 CURLOPT_FOLLOWLOCATION 并尝试自己处理重定向，但我仍然无法正确处理（服务器返回一个非常奇怪的重定向网址，我认为我没有正确执行这部分）

但如果有人能帮助我，我将非常感激......

这是我的代码：

    //setup Curl
  $cookiename = substr($from,4,5);
  $cookiefile = $cookiename . ".txt";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  curl_setopt($ch, CURLOPT_HEADER, 1); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (Windows; MSIE 6.0; U; Windows NT 5.1)");
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
  curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);

  //read login page
  curl_setopt($ch, CURLOPT_URL, "Login.aspx"); 
  $result = curl_exec ($ch);

  echo $result;



  // extract values for hidden form fields __REQUESTDIGEST __VIEWSTATE __EVENTVALIDATION fields

  //extract __REQUESTDIGEST
  $start = strpos($result,"id=\"__REQUESTDIGEST\" value=\"") + 28;
  $end = $start + 157;
  $rdigest = substr($result  , $start  , $end - $start );

  //extract __VIEWSTATE
  $start = strpos($result,"id=\"__VIEWSTATE\" value=\"") + 24;
  $end = $start + 16300;
  $vstate = substr($result  , $start  , $end - $start );
  $vstate = urlencode($vstate);

  //extract __EVENTVALIDATION
  $start = strpos($result,"id=\"__EVENTVALIDATION\" value=\"") + 30;
  $end = $start + 120;
  $event = substr($result  , $start  , $end - $start );
  $event = urlencode($event);


  //set login form values and login

  //curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_REFERER, 'Login.aspx');
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, '__REQUESTDIGEST=' . $rdigest . '&__VIEWSTATE=' . $vstate . '&__EVENTVALIDATION=' . $event . '&UserName=' . $from . '&Password=' . $password);
  $result = curl_exec ($ch);

  echo $result;

  //extract __redirect
  $start = strpos($result,"Location:") + 10;
  $end = strpos($result,".aspx") +5;
  $redirect = substr($result  , $start  , $end - $start );
                $redirect = "https://www.domain.com/" . $redirect;

  echo $redirect ."<br /><br />";

  echo $result;

  curl_setopt($ch, CURLOPT_URL, $redirect);
  $result = curl_exec ($ch);

  echo $result;

这是输出：

Answer 1

我将我的 useragent 行更新为不同的用户代理，突然 .ASPXAUTH cookie 在 cookie 文件中被正确（并且自动）设置:)

换句话说，我改变了这一行：

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (Windows; MSIE 6.0; U; Windows NT 5.1)");

对此：

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 ( .NET CLR 3.5.30729)");

现在这两个 cookie 都是由curl 自动设置的——没问题。

万岁！
