如何使用Laravel闭包调用控制器的__invoke（）方法？

Question

In my Laravel application I have created a controller named InvokableController. It contains this function:

public function __invoke()
{
    return view('home');
}

I'd like to be able to call the __invoke method, like this:

Route::get('/', function () {
    $invokableObj = new InvokableController();
    $invokableObj();
})->name('home');

While this works:

Route::get('/', 'InvokableController')->name('home');

It's not what I'm looking for. I'd like to call the invoke method in this manner:

$invokableObj = new InvokableController();
$invokableObj();

I tried with and without the parentheses after InvokableController , on the line that assigns $invokableObj , with no luck.

I don't get any error messages. I tried returning something else at the bottom of the closure, like the number 1, and it renders 1 in the browser, so I know we're getting through the previous lines of code.

APP_DEBUG is true . Other error messages are rendered where I mess up. Does that make this some type of logical error?

Its just a class, so $invokableObj->__invoke() should work just fine. Or you can use laravel DI:

app()->call(InvokableController::class . '@__invoke');

Route::get('/', function () {
    return app()->call(InvokableController::class . '@__invoke'); 
    // or
    $invokableObj = new InvokableController();
    return $invokableObj->__invoke();
})->name('home');
