php - Codeigniter 3 索引方法行为异常

Question

我在子域上有一个 CodeIgniter 项目。现在，当我访问 sub.example.com 时，它会加载一个 login page 并在成功登录后重定向到仪表板。登录并建立 session 后，访问 sub.example.com/login/ 将自动重定向到 仪表板页面。现在这是我的问题。成功登录后，访问 sub.example.com 不会重定向到任何地方，它只是加载登录页面。但是访问 sub.example.com/index.php 会将我重定向到仪表板页面。

由于某种原因，我的索引方法被调用或正常工作。

这是我的代码。

.htaccess

IndexIgnore *
php_value date.timezone Asia/Kolkata

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]


## Remove www from URL
RewriteCond %{HTTP_HOST} ^www\.
RewriteRule ^(.*)$ https://sub.example.com/$1 [R=301,L]

## Redirect to HTTPS
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^sub.example.com$
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

config.php

if ($_SERVER['REMOTE_ADDR'] == "127.0.0.1") {
    $config['base_url'] = "http://" . $_SERVER['SERVER_NAME'];
} else {
    $config['base_url'] = "https://" . $_SERVER['SERVER_NAME'];
}

routes.php

$route['default_controller'] = 'root';
$route['root_controller'] = 'root';

/*API CONTROLLER*/
$route['api_controller'] = 'api';

/*Guest Controller*/
$route['guest_controller'] = 'guest';

$route['search/(:any)'] = 'root/search/$1';
$route['search/(:any)/(:num)'] = 'root/search/$1/$2';

$route['export/(:any)'] = 'root/export/$1';

root controller

public function __construct()
    {
        parent::__construct();
        $this->default_data = array("project_name" => PROJECT_NAME);
        if ($this->router->method == "privacy_policy") {
            return;
        }

        $this->load->library('session');

        if ($this->router->method == "login") {
            if ($this->session->userdata("username")) {
                redirect(base_url("dashboard/"));
            }
        } else {
            if (!$this->session->userdata("username")) {
                redirect(base_url("login/"));
            }
        }

        //Set MYSQL timezone
        $this->db->query("SET time_zone = '+05:30'");
    }

    /**
     * Dashboard View
     */
    public function index()
    {
        redirect(base_url("/dashboard/"));
    }

    /**
     * Login View
     */
    public function login()
    {
        $data = $this->default_data;
        if ($_POST) {
            $username = $this->input->post("username");
            $plain_password = $this->input->post("password");
            $this->load->model("authenticate");
            if (!$this->authenticate->auth($username, $plain_password)) {
                $data['message'] = "Invalid Credentials";
            }
        }
        $this->load->view('login', $data);
    }

Update

1. 忘了说我只在远程服务器上遇到这个问题。在本地主机上它工作正常。

她的想法 - 在加载 session 对象后添加:

    if ($this->session->userdata("username") && $this->router->method == "index") {
            redirect(base_url("dashboard/"));
    }
