我遇到了一个相当奇怪的问题。
我正在尝试使用 PHP 中的 curl 登录到远程 moodle 安装。
我有一个 curl 命令,在终端中完美运行。
当我将相同的内容翻译成 PHP 时,它可以正常工作,但它只是无法登录。与通过终端成功登录的确切值相比,它在 PHP 中会使登录系统失败,从而无法登录。相反,它会再次返回登录页面。
我的 cURL 命令(数据部分省略了用户名和密码):
curl 'http://moodle.tsrs.org/login/index.php'

-H 'Origin: http://moodle.tsrs.org'
-H 'Accept-Encoding: gzip, deflate'

-H 'Connection: keep-alive'
对应的PHP代码:
function login() {
$username = $_POST['username'];
$password = $_POST['password'];
if(!isset($_POST['username']) || !isset($_POST['password'])) {
echo "No login data received";
return;
}
$creq = curl_init();
$data = array('username' => $username, 'password' => $password, 'testcookies'=> '1');
$headers = array('Pragma: no-cache', 'Origin: http://moodle.tsrs.org', 'Accept-Encoding: ', 'Accept-Language: en-US,en;q=0.8', 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.65 Safari/537.36', 'Content-Type: application/x-www-form-urlencoded', 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8', 'Cache-Control: no-cache', 'Cookie: MoodleSession=ngcidh028m37gm8gbdfe07mvs7; MOODLEID_=%25F1%25CD%2519D%25B2k%25FE%251D%25EFH%25E5t%25B1%2503%258E; MoodleSessionTest=NhzaTNij6j; _ga=GA1.2.925953522.1416155774; _gat=1; __utmt=1; __utma=147409963.925953522.1416155774.1416642544.1416692798.3; __utmb=147409963.1.10.1416692798; __utmc=147409963; __utmz=147409963.1416155774.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)', 'Connection: keep-alive' );
curl_setopt_array($creq, array(
CURLOPT_URL => 'http://moodle.tsrs.org/login/index.php',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POST => true,
CURLOPT_ENCODING => '',
CURLINFO_HEADER_OUT => true,
CURLOPT_POSTFIELDS => $data,
CURLOPT_HTTPHEADER => $headers,
CURLOPT_FOLLOWLOCATION => false
));
$output = curl_exec($creq);
echo print_r(curl_getinfo($creq));
echo "\n" . $output . "\n";
}
并且curlinfo的输出:

有人知道这可能是什么原因吗?我已尝试使用COOKIEFILE和COOKIEJAR替换硬编码的cookie,但没有任何变化。
Referer
头和一个Accept-Encoding
值。PHP cURL根本不包括Referer,而是留空了Accept-Encoding。@RichardTheKiwi,只是为了澄清,您的问题是否也与moddle有关? - HPierce
