Class '...\Input' not found - laravel

Question

I want to implement a search option on my Laravel application, but had this error:Class 'Illuminate\Support\Facades\Input' not found, I have tried to add this row at config/app like this:
'aliases' => [
....
'Input' => Illuminate\Support\Facades\Input::class,
Also at Controller I have added those rows:
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
At Route I have added
Route::any('/search',function(){
$image_tmp = $request->image;
$fileName = time() . '.'.$image_tmp->clientExtension();
$q = Input::get ( 'q' );
$book = Book::where('title','LIKE','%'.$q.'%')->get();
if(count($book) > 0)
return view('home')->withDetails($book)->withQuery ( $q );
else return view ('home')->withMessage('No Details found. Try to search again!');
});
But still it doesn't work.

Answer 1

Try this
config/app.php
use Request instead of Input
'aliases' => [
....
'Input' => Illuminate\Support\Facades\Request::class,
And your controller
use Illuminate\Http\Request;
and remove use Illuminate\Support\Facades\Input; top of your code

Answer 2

you have used the class in the controller but your route is never going to one as you are using a closure. so add Input class in your web.php file. at the top of your web.php file add
<?php
use Illuminate\Support\Facades\Input;
if you are using any latest version of laravel, the Input class no longer exists. so use Request class instead
<?php
use Illuminate\Http\Request;
you can use request() global helper too to get request values.
however i would suggest you to not use closure, rather use controller for logical operation.
