Codeigniter default route Error

Codeigniter default route Error

Recently, codeigniter encountered an inexplicable bug. As follows:

Configure a default route in config/routes:

 
 

  
  
$route['default_controller'] = "homePage/index";   
 
 

As a result, Error 404 is returned when accessing the root url, while access/homePage/index is normal. If you have no idea, you can read the routing configuration code from the framework. This line of code in system/core/Router. php was suddenly realized.

 
 

  
  
function _set_routing(){   
  
  
...   
  
  
$this->default_controller = ( ! isset($this->routes['default_controller']) OR $this->routes['default_controller'] == '') ? FALSE : strtolower($this->routes['default_controller']);   
  
  
...   
  
  
}   
 
 

Strtolower is called here to convert default_controller to lower-case, and errors will occur when the method and class are read later. I don't know if this is a bug, but I am still interested in it.

The solution is that the default controller should not contain uppercase letters or remove the strtolower of this line of code in Router. php.
