Why function is returning Undefined

Question

I am trying to get a return json of the function and associate it to a variable, because so I take the need to structure the received data with page from within this function and I can work in another function this, but it is not working out the return is being undefined, see the code

var token = getCookie("token");
var json = {};
$scope.query = consumeService (token, JSON.stringify(json), "funcionario/getAllFuncionarios", "POST", "alerta", function(result){
    var r = result;
    return r;
});

console.log("Query :" +$scope.query);

Answer 1

Perhaps because it is an asynchronous request, it tries to put the $Scope variable inside Function:

var token = getCookie("token");
var json = {};
consumeService (token, JSON.stringify(json), "funcionario/getAllFuncionarios", "POST", "alerta", function(result){
    var r = result;
    console.log("Result :" + r);
    $scope.query = r;
});

lucianohdr has already sung the ball. This request you are trying to make is asynchronous. You will need to use a callback method to treat.

function chamar(){
    consultar(function(result){
        console.log(result);
    });
}

function consultar(callback) {
    var token = getCookie("token");
    var json = {};
    consumeService (token, JSON.stringify(json), "funcionario/getAllFuncionarios", "POST", "alerta", function(result){
        callback(result);
    });
}
