                });     

Route:

Route::post('login','loginController@login')->name('loginData'); 

Controller:

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Auth;
use Session;
class loginController extends Controller
{
    public function login(Request $request){
        $credentials = $request->only('email', 'password');
        if (Auth::attempt($credentials)) {
          //  print_r($request->all());

            session()->put('role', Auth::user()->Role);

            $request->session()->flash('message', 'New customer added successfully.');
            $request->session()->flash('message-type', 'success');
           return response()->json(['status'=>'success']);
           return back();

        }else{
            $request->session()->flash('message', 'you have entered an invalid email address or password. please try again');
            $request->session()->flash('message-type', 'danger');
            return response()->json(['status'=>'error']);
            return back();
        }

    }
}
