为什么CodeIgniter重定向功能不能在实时服务器上运行，但在localhost上运行正常

Question

安装后。我将登录设置为默认控制器，并希望转到管理员的仪表板，但在提交登录详细信息而不是重定向到仪表板后，它将重定向到再次安装控制器。

任何人都可以帮助我吗？

我的登录控制器是login.php：

<?php
if (!defined('BASEPATH'))
    exit('No direct script access allowed');

class Login extends CI_Controller
{


    function __construct()
    {
        parent::__construct();
        $this->load->database();

    }

    /***default functin, redirects to login page if no admin logged in yet***/
    public function index()
    {
        if ($this->session->userdata('admin_login') == 1)
            redirect(base_url() . 'index.php?admin/dashboard', 'refresh');

        if ($this->session->userdata('doctor_login') == 1)
            redirect(base_url() . 'index.php?doctor/dashboard', 'refresh');

        if ($this->session->userdata('patient_login') == 1)
            redirect(base_url() . 'index.php?patient/dashboard', 'refresh');

        if ($this->session->userdata('nurse_login') == 1)
            redirect(base_url() . 'index.php?nurse/dashboard', 'refresh');

            redirect(base_url() . 'index.php?laboratorist/dashboard', 'refresh');

您是否检查了实时服务器中的cookie？我曾经历过类似你的东西。 redirect()函数在实时服务器中不起作用，但实际上不能正常工作的是每次加载页面时user_data会话已经消失。我只是在实时服务器中允许cookie $config['sess_cookie_name'] = "MY-COOKIE*******"，一切顺利。
