重命名类用户插入\u控制器扩展CI\u控制器{
到类用户插入扩展CI\U控制器{
然后通过example.com/index.php/userinsert访问该站点
您的应用程序/config/routes.php
必须如下所示
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

/*
| -------------------------------------------------------------------------
| URI ROUTING
| -------------------------------------------------------------------------
| This file lets you re-map URI requests to specific controller functions.
|
| Typically there is a one-to-one relationship between a URL string
| and its corresponding controller class/method. The segments in a
| URL normally follow this pattern:
|
|   example.com/class/method/id/
|
| In some instances, however, you may want to remap this relationship
| so that a different class/function is called than the one
| corresponding to the URL.
|
| Please see the user guide for complete details:
|
|   https://codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There are three reserved routes:
|
|   $route['default_controller'] = 'welcome';
|
| This route indicates which controller class should be loaded if the
| URI contains no data. In the above example, the "welcome" class
| would be loaded.
|
|   $route['404_override'] = 'errors/page_missing';
|
| This route will tell the Router which controller/method to use if those
| provided in the URL cannot be matched to a valid route.
|
|   $route['translate_uri_dashes'] = FALSE;
|
| This is not exactly a route, but allows you to automatically route
| controller and method names that contain dashes. '-' isn't a valid
| class or method name character, so it requires translation.
| When you set this option to TRUE, it will replace ALL dashes in the
| controller and method URI segments.
|
| Examples: my-controller/index -> my_controller/index
|       my-controller/my-method -> my_controller/my_method
*/
$route['default_controller'] = 'welcome';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

/* CUSTOM ROUTES */
$route['userinsert'] = 'Userinsert';

在config.php中
replace
$config['index_page'] = 'index.php';  

到
$config['index_page'] = '';

您能展示一下config/routes.php的样子吗？404错误可能是由于routes中的错误配置造成的you@Kuru$route['default\u controller']='welcome'；$route['404\u override']=''；$route['translate\u uri\u破折号']=FALSE；@dawoodbasharat我非常感谢阅读这篇将Userinsert\u controller.php重命名为Userinsert\u controller.phpSir仍然是相同的问题应用程序/controller
中的控制器是吗？是的，这就是为什么我将其命名为Userinsert\u controller只是为了便于记忆。但是我更改了UserinsertCan的名称，你可以给我们一个屏幕截图fr从您的文件夹结构？很抱歉，我没有得到它！！我需要向您发送我的文件在哪些文件夹中的屏幕截图，还是需要给您配置文件的屏幕截图？让我再次检查一下，除了这一行/*自定义路由*/$route['userinsert']='Userinsert'；您如何访问该网站？使用哪个url？以下是它使用的url您建议我使用的url，但问题是remainsHappy编码（Y）我可以向你寻求更多的帮助吗？当然可以。如果你想修复一些错误，你可以提出新问题。@我有一些新问题，它与会话有关！如果你不介意，我可以通过你的电子邮件或其他类似的东西与你联系吗？如果你觉得不方便，请不要介意
