更新:
我想知道是否有人可以查看我的答案,看看其中是否有任何漏洞。
在以下位置使用 codeingiter 和 session 时有一个记录良好的问题:
Duplicated "set-cookie: ci-session" fields in header by codeigniter
总而言之,每次调用 set_userdata 时,codeigniter 都会设置 cookie。
我在以下位置找到了部分解决方案:

此解决方案的唯一问题是需要在任何地方插入代码。有没有一种简单的方法可以清除所有标题?我已经稍微修改了代码以消除 php 错误,但是有什么方法可以使用 Hook 或其他东西吗?
<?php
class MY_Controller extends CI_Controller
{
public function __construct()
{
parent:: __construct();
}
//See (modified from) http://ha17.com/1745-bigip-f5-header-max-size-collides-with-codeigniters-bizarre-session-class/
protected function _removeDuplicateCookieHeaders ()
{
// clean up all the cookies that are set...
$headers = headers_list();
$cookies_to_output = array ();
$header_session_cookie = '';
$session_cookie_name = $this->config->item('sess_cookie_name');
foreach ($headers as $header)
{
list ($header_type, $data) = explode (':', $header, 2);
$header_type = trim ($header_type);
$data = trim ($data);
if (strtolower ($header_type) == 'set-cookie')
{
header_remove ('Set-Cookie');
$cookie_value = current(explode (';', $data));
list ($key, $val) = explode ('=', $cookie_value);
$key = trim ($key);
if ($key == $session_cookie_name)
{
// OVERWRITE IT (yes! do it!)
$header_session_cookie = $data;
continue;
}
else
{
// Not a session related cookie, add it as normal. Might be a CSRF or some other cookie we are setting
$cookies_to_output[] = array ('header_type' => $header_type, 'data' => $data);
}
}
}
if ( ! empty ($header_session_cookie))
{
$cookies_to_output[] = array ('header_type' => 'Set-Cookie', 'data' => $header_session_cookie);
}
foreach ($cookies_to_output as $cookie)
{
header ("{$cookie['header_type']}: {$cookie['data']}", false);
}
}
}
最佳答案
编辑:仅当您使用 $this->load->view() 时才使用此代码。如果您在 Controller 中使用 echo 权利,这将导致在删除 header 之前输出甚至被删除。
编辑需要 php 5.3 或更新版本。
我找到了一种方法,我认为我可以帮助其他人解决这个问题。我还没有完美地测试它,但它似乎有效。
