Laravel 302 redirect issue - laravel

Question

I am trying to get info from action, but when click, just page refresh and in console I get code 302 and stay on current page.
I read a lot of similar topics here but found nothing.
I am trying to execute http://laravel2.lo/getUserChannels?user_id=2
Laravel 5.7.16
route:
Auth::routes();
Route::group(['middleware' => ['auth']], function () {
Route::view('createUser', 'createuser');
Route::view('createChannel', 'createchannel');
Route::view('joinChannel', 'joinchannel');
Route::get('profile', 'UserController#profile');
Route::get('users', 'UserController#users');
Route::get('getChannelUsers', 'UserController#getChannelUsers');
Route::get('getUserChannels', 'ChannelController#getUserChannels');
});
ChannelController:
class ChannelController extends Controller
{
public function getUserChannels(Request $request)
{
$this->validate($request, [
'user_id' => 'required|integer',
]);
/** #var User $user */
$user = User::find($request->user_id);
return view('singleuser', ['channels' => $user->channels, 'username' => $user->name]);
}
}
In the log file no errors.
Thanks for any help and advise.

Answer 1

I don't think you'll receive query params as anything other than strings, so your integer validation fails.
To improve your error handling you could customize your App\Exceptions\Handler, catch your ValidationException errors with something like get_class() or instanceOf and do some neat stuff there
And of course you could not use query params at all by using Route::get('getUserChannels/{id}', 'controller#show'); and access it /getUserChannels/2 - then you could probably validate it as an integer
You could go with
Route::get('getUserChannels/{id}', ...
public function getUserChannels($id)
{
$user = User::findOrFail($id);
return view('singleuser', [
'channels' => $user->channels,
'username' => $user->name
]);
}
Then it would just throw a 404 if string, not found etc...

class ChannelController extends Controller
{
public function getUserChannels(Request $request)
{
$validator = \Validator::make($request->all(), ['user_id' => 'required|integer']);
if($validator->fails())
{
$error = $validator->errors()->first();
dd($error);
}
/** #var User $user */
$user = User::find($request->user_id);
return view('singleuser', ['channels' => $user->channels, 'username' => $user->name]);
}
}
