How to pass a data from Javascript to PHP Laravel?

Question

what I'm trying to do is a function in javascript that sends a simple data to a laravel controller and then upload it to the database, the problem I have is that until now I have not been able to find a way to send this data, always I get error 500.

Laravel Controller:

public function crearRegistro(Request $request){

$registro = new Registro();
$registro->indicador = $request->indicador;
$registro->save(); 
}

Javasript Function:

    $scope.calculoIndicador = function(){
  $http.post("/calculoIndicador")
  .then(function(response) {
    });
  $scope.indicador = 5 +5;
   alert('Se ha guardado correctamente');

}

view:

<input class="btn btn-success" style="" ng-click="calculoIndicador()" 
 type="submit" value="Enviar"/>

Route:

Route::post('/calculoIndicador', 'TecnologiaController@crearRegistro');

If you get 500 in ajax requests, you may not be able to see the stack trace in your browser, but you can still find the stack trace in the file storage/logs/*.log (the file name may vary.) What does the trace say when your 500 occurred? They come with timestamps, so it should be easy to spot :) — Collapsed PLUG

(First, sorry with my bad english)

I assume that you use Laravel 5.6. On controller you have to use: $request->all() method to get the data passed to controller via post on javascript. On your code i assume yout want the "indicador", so:

$requestData = $request->all();
$registro->indicador = $requestData['indicador'];

But on your javascript you have to pass "indicador" as parameter on post request data. So, on javascript (or typescript of Angular) post do something like this:

$http.post("/calculoIndicador", {indicador: 'your_data'}).then(
    function(response) {
      $scope.status = response.status;
      $scope.data = response.data;
    }, function(response) {
      $scope.data = response.data || 'Request failed';
      $scope.status = response.status;
    }
)

Can you update this page with stack trace of this error?
