404页面未找到codeigniter url

Question

我是使用 codeigniter 的初学者。我正在使用以下 url "http://localhost/ci/index.php/shopcart" 来访问控制器，我收到错误 404 page not found

控制器代码

     <?php

    class Cart extends CI_Controller { // Our Cart class extends the Controller class

        function Cart()
        {
            parent::CI_Controller(); // We define the the Controller class is the parent. 

        }


    }

        function index()
        {
            $this->load->model('cart_model'); // Load our cart model for our entire class 
            $data['products'] = $this->cart_model->retrieve_products(); // Retrieve an array with all products
            $data['content'] = 'cart/products'; // Select our view file that will display our products
            $this->load->view('index', $data); // Display the page with the above defined content
        }
?>

型号代码

<?php 

class Cart_model extends Model { // Our Cart_model class extends the Model class
// Function to retrieve an array with all product information
    function retrieve_products(){
        $query = $this->db->get('products'); // Select the table products
        return $query->result_array(); // Return the results in a array.
    }  

}

路线

$route['default_controller'] = "shopcart";

自动加载

$autoload['libraries'] = array('cart' , 'database');
$autoload['helper'] = array('form');

Answer 1

codeigniter 适用于 base_url~/index.php/class_nm/function/segment3。现在在你的情况下更改文件名Cart.php。

localhost/ci/index.php/cart/index

并确保你的函数index 是public，我想它会解决你的问题:)

Answer 2

您收到 404 页面未找到错误，因为未定义控制器“购物车”。相反，您已经定义了一个控制器“购物车”。所以你应该试试localhost/ci/index.php/cart。

Answer 3

也尝试添加 url 助手。这对我行得通！
