  }else{
    echo ' No parameter ';
  }*/
  // Get all the parameters 
  /*$res = $request->all();
  dd($res);*/
  //2. Determine the request type

  if($request->isMethod('post')){
    echo 'Yes';
  }else{
    echo 'No';
  }*/
  // Judge whether it is ajax Request 
  /*$res = $request->ajax();

public function response(){

  return response()->json($data);*/
  // Redirect
