Codeigniter路由行为与控制器魔术方法__call

Question

The segments in a URI normally follow this pattern in Codeigniter:

XYZ.com/Class/Method/param1/param2

This works as expected when the called method is defined in the controller, but nothing works if I supply the URI with some undefined method to invoke the __call magic method that takes care of any undefined method.

__call is only invoked if its called from within the controller itself, not when I call some undefined method from the URI

Any explanation?

Thanks

In CodeIgniter, there is _remap. So if you go to

XYZ.com/Class/UndefinedMethod/param1/param2

then _remap will be called (actually _remap will always be called, so we need to make sure that methods that do exist are called correctly).

function _remap($method, $params=array()){
    $funcs = get_class_methods($this);
    if(in_array($method, $funcs)){ // We are trying to go to a method in this class
        return call_user_func_array(array($this, $method), $params);
    }
    // else do something else
}
