Is it possible to pass a variable from a method to an intermediary (middleware)?

Question

Python

All health! Please help me understand.
For example, I have a FooController controller with a myMethod method, and myMiddleware middleware
The route says:
Route::post('/slug','[email protected]');
The controller says:

#...
class FooController extends Controller
{
    public function __construct()
    {
        $this->middleware('myMiddleware', ['only' => ['myMethod']]);
    }
    public function myMethod(Request $request)
    {
        #...
    }
    #...
}

In this case, the intermediary works with the Request data that comes from the route, checks something, checks, etc. And only then, if everything is OK, the method executes. Is it possible to pass data directly from the body of the method to the intermediary? Or it contradicts the very meaning of the intermediary and it is necessary to inject dependencies, etc.

Answer 1

You probably have a problem with the encoding in the excel file.

Answer 2

there is a character in the file that cannot be displayed in ASKII

Answer 3

This contradicts the meaning of the mediator, because the meaning in it is to call the method after checking if everything is OK or throw an error if not.
If you want to call a check from a method, then you should just use some kind of helper class, and not specifically middleware.

Answer 4

a question arose, since middleware is being discussed here, is
it possible to call the midlleware handle method directly from the controller and how to do it?
