Question

在我更改了我的codeigniter文件后，屏幕出现了像这样的diplay错误

http://webdomain.com/index.php/login/login已经结果在太多重定向中。清除本网站的cookie或允许第三方cookie可以解决问题。如果没有，它可能是一个服务器配置问题，而不是您的计算机的问题。学习更多关于这个问题。错误代码：ERR_TOO_MANY_REDIRECTS

它可能由无限循环重定向导致我尝试修复几个小时我不在哪里问题有我的代码，但我无法弄清楚我的代码中的错误是什么，我使用谷歌浏览器的Chrome浏览器< / p>

我的路由默认控制器是index.php

这是login.php（控制器）代码

<?php if(!defined('BASEPATH')) exit('error');

class Login extends CI_Controller{

public function __construct(){
    parent::__construct();

    $this->load->model('login_model');
    $this->load->library('session');
    $this->load->database();
    $this->load->helper('url'); 
    $this->load->helper('form');
    $this->load->helper('security');        
}

public function index(){
    redirect('login/login');
}

public function login(){
    if($this->session->userdata('logged_in')==TRUE){
            redirect ('login/login');
        }else{
            $this->load->library('form_validation');
            //for view filters
            $this->form_validation->set_rules('username','Username','required|min_length[5]|max_length[125]');
            $this->form_validation->set_rules('password','Password','required|min_length[5]|max_length[20]');
            if($this->form_validation->run()==FALSE){
                $this->load->view('login/login_admin');
            }else{
                $username = $this->input->post('username');
                $password = $this->input->post('password');

                //$this->load->model('login_model');
                $query=$this->Login_model->data_pengguna($username,$password,1);
                    if($query->num_rows()==1){
                        //jika benar
                        foreach ($query->result() as $row){
                            $this->load->library('encrypt');
                            //generate hash password
                            $hash=$this->encrypt->sha1($password);
                            //mengcompare result hash in database\
                            if($hash!=$row->hash){
                                //tidak sama
                                $data['login_fail']=true;
                                $this->load->view('login/login_admin',$data);

                            }else{
                                $data=array(
                                    'id'=>$row->user_id,
                                    'username'=>$row->username,
                                    'logged_in'=>TRUE
                                );
                                //menyimpan session
                                $this->session->set_userdata($data);
                                redirect ('login/home');
                            }
                        }
                    }
            }
        }
    }


public function logout(){

    $this->session->sess_destroy();
    redirect('login/login_admin');
}
}

?>

这里是login_model.php（模型）代码

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
Class Login_model extends CI_Model{
    function __construct(){
        parent::__construct();  
        $this->load->helper('url');
    }
    public function get_pengguna($username, $password, $status){
        $this->db->select('username','password','status');
        $this->db->from('userlogin');
        $this->db->where('username',$username);
        $this->db->where('password',$password);
        $this->db->where('status',$status);
        $query= $this->db->get();
        return $query->num_rows();
    }
    public function data_pengguna($username){
        $this->db->select('username');
        $this->db->from('userlogin');
        $this->db->where('username',$username);
        $query= $this->db->get('userlogin');
        return $query->row();
    }
}
?>

然后这个.htaccess

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]

在这个问题上坚持了几个小时..我也想知道为什么改变托管导致这样的问题。

先谢谢！

Answer 1

我的一个项目遇到了同样的问题。

我看到问题出在登录功能的索引功能和登录检查条件中。

您可以参考以下内容 -

public function index($msg = NULL){
    $this->is_logged_in(); //here i've added the condition to check whether user is logged in
    ['msg'] = $msg;
    $this->load->view('login_view', $data);
}

public function login(){ 
    $this->load->model('login_model');
    // Validate the user can login
    $result = $this->login_model->validate(); //validating the user into model

    // Now we verify the result
    if(! $result){ 
        // If user did not validate, then show them login page again
        $msg = '<font color=red>Invalid username and/or password.</font><br />';
        $this->index($msg);
    }else{            
            $this->redirect_other();
    }        
} //end function login()

Answer 2

从您的登录功能中删除第一个登录检查，正如您所说的默认功能是您在其中调用login / login的索引。你不需要再次重复它。

在codeigniter上重定向循环
