错误 404

本地主机 Apache/2.4.9 (Win32) OpenSSL/0.9.8y php/5.4.27

我的 config.php

$config['base_url'] = 'http://localhost:82/admin';

$config['index_page'] = '';

$config['uri_protocol']	= 'REQUEST_URI';

我的路线.php

$route['default_controller'] = 'admin/index';
$route['404_override'] = '';
//$route['translate_uri_dashes'] = FALSE;

我的控制器 Admin.php

【问题讨论】：

显示您尝试访问的控制器代码和 URL

我添加了有问题的网址

什么版本的 CI

你的admin文件名Admin.php首字母大写

在您的基本网址中以正斜杠 / 结束它，例如 $config['base_url'] = 'http://localhost:82/yourprojectname/';

【参考方案1】：

也许你有 .htaccess，因为你的控制器看起来不错，但你仍然得到这个答案。请尝试在您的根目录中添加 .htaccess。

【参考方案2】：

routes.php

$route['default_controller'] = 'admin/index';

你猜应该是？

$route['default_controller'] = 'admin';
