Authorization isn’t executed in laravel - laravel

Question

This is form ‘login’, when I’m enter information in input and after press button ‘login’ I move to page with audit where 0 is authorization isn't executed and 1 is authorization is executed. I'm trying to create authorization in laravel.
I did it in other project in order to understand how it works and then all was good. Now I'm trying to transfer it in my main project but when I am logging in nothing work.
I don't have any mistake, authorization is simply not executed. I will grateful for any help.
Registration function
public function sub(ContactSignup $request){
if(Auth::check()){
return redirect(route('user.mainpage'));
}
$contact = new SignUps();
$contact->name = $request->name;
$contact->surname = $request->surname;
$contact->age = $request->age;
$contact->password = bcrypt($request->password);
$contact->email = $request->email;
$contact->save();
Auth::login($contact);
if($contact){
Auth::login($contact);
return redirect(route('user.sign-up'))->with('success', 'Реєстрація пройшла успішно');
}
}
Function login
public function subin(ContactSignin $request){
if(Auth::check()){
return redirect()->intended(route('user.mainpage'));
}
$contact = $request->only(['email', 'password']);
if(Auth::attempt($contact)) {
dd(1);
}
else {
dd(0);
}
return redirect()->intended(route('user.mainpage'));
}
Web.php
<?php
use Illuminate\Support\Facades\Route;
Route::get('/', function () {
return redirect()->route('mainpage');
});
Route::name('user.')->group(function(){
Route::view('mainpage', 'mainpage')->middleware('auth')->name('mainpage');
Route::get('/signin', function(){
if(Auth::check()){
return redirect(route('user.mainpage'));
}
return view('signin');
})->name('sign-in');
Route::post('/signin', [\App\Http\Controllers\ContactController::class, 'subin'])->name('sign-in');
Route::get('logout', function(){
Auth::logout();
return redirect('/');
})->name('logout');
Route::get('/signup', function(){
if(Auth::check()){
return redirect(route('user.mainpage'));
}
return view('signup');
})->name('sign-up');
Route::post('/signup', [\App\Http\Controllers\ContactController::class, 'sub'])->name('sign-up');
});
Route::get('/mainpage', function () {
return view('mainpage');
})->name('mainpage');

Answer 1

in your methods inside your controller you have form request class called ContactSignin
in this class you have code
public function authorize()
{
return false;
}
make it true
The form request class is responsible of validating your request ,
also contains an authorize method. Within this method, you may determine if the authenticated user actually has the authority to update a given resource
since you handle authorization logic for the request in the routes by provide
middleware('auth') it is no need to check for use authentication in your form request class

Answer 2

first you don't have route named ('user.mainpage') you have to define it in web.php
second , since you named your rout in
Route::get('/mainpage', function () {
return view('mainpage');
})->name('mainpage');
, you must redirect to the name of the route not to the path
for example if your route is ('/api/main')->name('main') , you have to put the rout name in the redirect method , for example redirect(route('main'));
