PHP Curl 登录 https

Question

我正在尝试使用 php curl 登录 ets.org/toefl 帐户。但我无法登录该网站。我通常会收到一条错误消息，说服务器正忙，但当我使用浏览器登录时它会起作用。我已附上我的代码。谁能看出出了什么问题吗？

<?php
include('simple_html_dom.php');

$login_url = 'https://toefl-registration.ets.org/TOEFLWeb/logon.do';

$username='****';
$password='***';
$ck = 'cookie.txt';

$agent = 'Mozilla/5.0 (Windows NT 6.1; rv:22.0) Gecko/20100101 Firefox/22.0';
// extra headers
$headers[] = "Connection: keep-alive";
//$headers[]= "Accept-Encoding: gzip, deflate";


$ch = curl_init();

curl_setopt($ch, CURLOPT_HEADER,  0);
curl_setopt($ch, CURLOPT_HTTPHEADER,  $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);         
curl_setopt($ch, CURLOPT_USERAGENT, $agent); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 

curl_setopt($ch, CURLOPT_COOKIEJAR, $ck);
curl_setopt ($ch, CURLOPT_COOKIEFILE, $ck);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
//curl_setopt($ch, CURLOPT_URL, 'https://toefl-registration.ets.org/TOEFLWebextISERLogonPrompt.do');

$output = curl_exec($ch);
//echo $output;

$html = new simple_html_dom();
$html = str_get_html($output);
$e = $html->find(".loginform");
$a = $e[0]->find('input');
$str = $a[0]->outertext;
preg_match("/value=\"(.*)\"/",$str,$match);
$h_attr = $match[1];

$fields['org.apache.struts.taglib.html.TOKEN'] = $h_attr;
$fields['currentLocale']= 'en_US';
$fields['username'] = $username;
$fields['password'] = $password;
$fields['x'] = 11;
$fields['y'] = 4;
//print_r($fields);
//echo "\r\n";
$POSTFIELDS = http_build_query($fields); 
//echo $POSTFIELDS;

$headers[] = "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
$headers[] = "Accept-Language: en-US,en;q=0.5";
$headers[]="Referer: https://toefl-registration.ets.org/TOEFLWeb/extISERLogonPrompt.do";

curl_setopt($ch, CURLOPT_URL, $login_url); 
curl_setopt($ch, CURLOPT_HTTPHEADER,  $headers);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $POSTFIELDS); 
$result = curl_exec($ch);
print $result;

尝试将 CURL 脚本发送的 HTTP header 与浏览器发送的 header 进行比较(使用 Chrome 开发工具)。也许远程服务器由于缺少某些 header 信息而拒绝您。

确保 cookie 文件具有完全权限。来自 php.net:

When specifing CURLOPT_COOKIEFILE or CURLOPT_COOKIEJAR options, don't forget to "chmod 777" that directory where cookie-file must be created.
