Answer 1

you need to replace User::attempt with auth()->attempt
another thing you don't need to check uname and passowrd manually laravel do that for you inside the attempt method so it would be more efficient if
you delete those two lines
$user = User::where('uname',$a)->get()->last();
$pass = User::where('password',$b)->get()->last();
finally, depends on your User model you have name not uname so you need to update it like this
if (auth()->attempt(array('name' => $uname , 'password' => $password ))){
return "success";
} else {
return "Wrong Credentials";
}
