尝试将codeigniter应用程序从本地移动到 Cloud ，但收到错误说该页面无效（IP地址）当前无法处理此请求 .
HTTP错误500 .
重命名了Login.php控制器并使其成为login.php，因此出现此错误，否则就说明了
404找不到页面找不到您请求的页面 .
从其他帖子尝试了所有内容，例如将配置文件 $config['uri_protocol'] = 'AUTO'; 更改为路径信息，查询字符串，请求uri，orig路径信息但似乎无效 . 对服务器进行了更改，同时启用了mod_rewrite . 下面我附上routes.php，database.php，config.php，index.php和login.php，即控制器 .

| 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:
|
| http://codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There area two 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 what URI segments to use if those provided
| in the URL cannot be matched to a valid route.
