This exception:

MethodNotAllowedHttpException

is telling you that the method on your form is not the same as the method on your route.

So you have 2 options to solve this issue.

First option : Change route method type Your route has a GET

Route::get('/ajax',function(){
  return view('message');
});

but your form has a POST

so change it to:

Route::post('/ajax',function(){
  return view('message');
});

Second option: change your ajax-form method type

Route::get('/ajax',function(){
  return view('message');
});


  <script>
     function getMessage(){
        $.ajax({
           type:'GET',
           url:'/getmsg',
           data:{'_token': '{{ csrf_token() }}'},
           success:function(data){
              $("#msg").html(data.msg);
           }
        });
     }
  </script>

Regarding your question about CSRF . It protects against Cross Site forgery. You can read about it here: https://laravel.com/docs/5.4/csrf
