Php 代码点火器路由和slug给了我404

我正在一个客户端网站上工作，其中一部分用于检索新闻，这是我的第一个codeigniter应用程序，我遵循了CI教程、Slug和路由

我遇到的问题是，一切都很好，但如果要获得基于slug的记录，我会得到404。我所做的是从我的URL中删除index.php并对其进行测试，效果很好

这是我的路线。php

$route['default_controller'] = "welcome";
$route['404_override'] = '';

$route['news/(:any)'] = 'news/singe_news/$1';
$route['news'] = 'news';

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

class News_model extends CI_Model {


    function get_all(){

    $sql="SELECT * FROM news AS news";  
    $query=$this->db->query($sql);
    return $query->result();

    }

    //// get a single post

    function get_single($slug = FALSE) {

    if ($slug === FALSE)
        {
        $query = $this->db->get('news');
            return $query->result_array();
        }

    $query = $this->db->get_where('news', array('slug' => $slug));
    return $query->row_array();


    }


    function news_categories(){

     $sql="SELECT * FROM news_categories";  
     $query=$this->db->query($sql);
     return $query->result();

    }

}

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

class News extends CI_Controller {



    public function index()
    {
        $this->load->model('news_model');
        $data['results']=$this->news_model->get_all();
        $this->load->view('public/header', $data);
        $this->load->view('public/menu');
        $this->load->view('public/news-listing', $data);
        $this->load->view('public/footer', $data);
    }



    public function single_news($slug) {


        $this->load->model('news_model');
        $data['single_news'] = $this->news_model->get_single();

    /// if (empty($data['single_news']))
        /// {
            /// show_404();
            ///}

        $this->load->view('public/header');
        $this->load->view('public/menu');
        $this->load->view('public/single-news', $data);
        $this->load->view('public/footer'); 


    }

}

这是我的模型新闻\u model.php

$route['default_controller'] = "welcome";
$route['404_override'] = '';

$route['news/(:any)'] = 'news/singe_news/$1';
$route['news'] = 'news';

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

class News_model extends CI_Model {


    function get_all(){

    $sql="SELECT * FROM news AS news";  
    $query=$this->db->query($sql);
    return $query->result();

    }

    //// get a single post

    function get_single($slug = FALSE) {

    if ($slug === FALSE)
        {
        $query = $this->db->get('news');
            return $query->result_array();
        }

    $query = $this->db->get_where('news', array('slug' => $slug));
    return $query->row_array();


    }


    function news_categories(){

     $sql="SELECT * FROM news_categories";  
     $query=$this->db->query($sql);
     return $query->result();

    }

}

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

class News extends CI_Controller {



    public function index()
    {
        $this->load->model('news_model');
        $data['results']=$this->news_model->get_all();
        $this->load->view('public/header', $data);
        $this->load->view('public/menu');
        $this->load->view('public/news-listing', $data);
        $this->load->view('public/footer', $data);
    }



    public function single_news($slug) {


        $this->load->model('news_model');
        $data['single_news'] = $this->news_model->get_single();

    /// if (empty($data['single_news']))
        /// {
            /// show_404();
            ///}

        $this->load->view('public/header');
        $this->load->view('public/menu');
        $this->load->view('public/single-news', $data);
        $this->load->view('public/footer'); 


    }

}

美元slug从何而来

您的URI如下所示：www.example.com/controller/method/arg1/arg2/arg3（不带查询字符串）

少了什么吗

嗯，你应该做几件事：

使用autoload（config/autoload.php）加载您最常用的模型，或者如果这个模型没有广泛使用，至少在类构造函数中加载它

您没有将$slug参数传递给model方法，即使您要修复路由，这也不会起作用

$data['single_news']=$this->news_model->get_single（）

最好显示404，如果找不到slug，不要在fail时重新蚀刻所有数据

要修复404错误，请执行以下步骤：

检查.htaccess文件是否存在错误

检查配置中的uri_协议设置

尝试这样的路由：$route['news/（.+）$）？']=“news/singe_news/$1”；（这将取代新闻的两条路线）

更改
$route['news/（：any）]='news/singe_news/$1'至
$route['news/（：any）]='news/single_news/$1'图例，所以解决方案是1-正确的路由，2-向模型传递$slug，3-向类添加构造函数
