我正在尝试在codeigniter中创建一个简单的登录系统。当我点击我的按钮登录时，我收到一个错误：

The action you have requested is not allowed.

您所请求的操作是不允许的。

When I open my console I see this:

当我打开我的控制台时，我看到了这个：

POST http://localhost/PHP/PROJECT/CodeIgniter/ 403 (Forbidden)

POST http：// localhost / PHP / PROJECT / CodeIgniter / 403（Forbidden）

This is my view:

这是我的看法：

<body>
    <h1>LOG IN!</h1>
    <form action="" method="post">
        <label for="username">Username:</label>
        <input type="text" id="username" name="username" >
        <label for="password">Password</label>
        <input type="password" id="password" name="password" >
        <br>
        <button id="btn_login" name="btn_login" >LOG IN!</button>
    </form>
    <div class="errors" ><?php echo validation_errors(); ?></div>
</body>

This is my model:

这是我的模特：

<?php 
class User_model extends CI_Model {
    public $m_sUsername;
    public $m_sPassword;
    public $m_sEmail;
    public $m_sPicture;

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

    function get_user($username, $password)
    {
        $this->db->select("username","password");
        $this->db->from(user);
        $this->db->where('username',$username);
        $this->db->where('password',$password);
        $this->db->limit(1);
        $query = $this->db->get();
        return $query->num_rows();
    }
}

and this is my controller:

这是我的控制者：

<?php

class Login extends CI_Controller {

    function __construct()
    {
        parent::__construct();
        $this->load->library('session');
        $this->load->helper('form');
        $this->load->helper('url');
        $this->load->helper('html');
        $this->load->database();
        $this->load->library('form_validation');
        $this->load->model("User_model", "", true);
    }

    public function index()
    {
        if ($this->input->server('REQUEST_METHOD') == 'POST') {
            $username = $this->input->post("username");
            $password = $this->input->post("password");
            $this->form_validation->set_rules("username", "Username", "trim|required");
            $this->form_validation->set_rules("password", "Password", "trim|required");

            if ($this->form_validation->run() == FALSE) {
                //validation fails
                echo "Vul alle velden in";
            } else {
                //validation succeeds
                if ($this->input->post('btn_login') == "Login") {
                    //check if username and password is correct
                    $usr_result = $this->User_model->get_user($username, $password);
                    if ($usr_result > 0) { //active user record is present
                        echo 'Ingelogd!';
                    } else {
                        echo "Wrong!";
                    }
                }
            }
        }

        $this->load->view("admin/login_view.php");
    }
}

Does anyone know how to solve this problem?

有谁知道如何解决这个问题？

Thanks!

谢谢！

Check your config.php If,

检查你的config.php如果，

$config['csrf_protection'] = TRUE;

If it is set to true you need to use form_open(), this will auto append the ci_csrf_token. Otherwise you can just set to FALSE.

如果设置为true，则需要使用form_open（），这将自动附加ci_csrf_token。否则你可以设置为FALSE。

But its advisable to set it to TRUE. But you need to make sure all your request includes the ci_csrf_token including AJAX request.

但建议将其设置为TRUE。但是您需要确保所有请求都包含ci_csrf_token，包括AJAX请求。

Try this

尝试这个

<input type="hidden" name="<?php echo $this->security->get_csrf_token_name(); ?>" value="<?php echo $this->security->get_csrf_hash(); ?>">

#3

With me it was browser cache, once I cleared it, the form started working again.

在我看来它是浏览器缓存，一旦我清除它，表单就开始重新运行了。

#4

for me the problem was that I was loading the page in index, I changed as follow and it worked:

对我来说问题是我在索引中加载页面，我改变如下，它工作：

public function index()
{
    // Load Login Page
    redirect('login/login_page','refresh');

}

public function login_page()
{
    $data['title'] = 'Login Page';

    $this->load->view('templates/header', $data);
    $this->load->view('users/login_view', $data);
    $this->load->view('templates/footer');
}
