laravel send parameter in route - laravel

Question

Is thier anyway to do somethins like this ,
in web.php
Route::get('/test', 'testController#test');
in test Controller
public function test ($url)
{
//while $url store test in route
}
I know only if I send parameter I have to use
Route::get('/{test}', 'testController#test');
UPDATE
I want to do something like this
Route::get('/test', 'testController#test');
Route::get('/test2', 'testController#test');
in my controller
public function test ($url)
{
while $url store test,test2in route
}
LASTEST UPDATE
I dont want to use {url}
I want to make /test = $url when I enter to url/test
In my web.php I use this
Route::get('/test', 'testController#test');
Route::get('/test2', 'testController#test');
The reason that I want to do something like this because I want to make 1 function that alll route can use In my controller I do this .
public function test($url,$preview=null)
{
//$url shoud be test or test 2
try {
$test = (isset($preview)) ? test::where('test.id',$url)->first()
} catch (\Exception $e) {
return redirect('notfound');
}
}
I dont want todo something like this
Route::get('/test', 'testController#test');
Route::get('/test2', 'testController#test');
and In controller
public function test($preview=null)
{
//$url shoud be test or test 2
try {
$test = (isset($preview)) ? test::where('test.id','test)->first()
} catch (\Exception $e) {
return redirect('notfound');
}
}

Answer 1

You need to combine both elements
Route::get('/test/{url}', 'testController#test');
want to make /test = $url
You can't, but you can have /test?foo=$url instead. So you keep your route like
Route::get('/test', 'testController#test');
Then add Request $request as controller method argument (and you remove $url)
public function test(Request $request) {
...
Finally you obtain your url with
$url = $request->input('foo');

Answer 2

Your Route
Route::post('/test', 'testController#test')->name('test);
If you use blade.
<a href="{{ route('test') }}"
onclick="event.preventDefault();
document.getElementById('test_id').submit();">
Test Click
</a>
{!! Form::open(['url' => route('test'), 'method' => 'post', 'id' => 'test_id']) !!}
<input type="hidden" name="url" value="{{ $url}}">
{!! Form::close() !!}
In your controller.
public function test(Request $request)
{
$data = $request->all();
$url = $data['url'];
//do something with your url...
}
