Angularjs multiple $http.get request

Question

I need to do two $http.get call and I need to send returned response data to my service for doing further calculation.

I want to do something like below:

Answer 1

I had a similar problem recently so I'm going to post my answer also:

In your case you only have two calculations and it seems to be the case this number is not mutable.

But hey, this could be any case with two or more requests being triggered at once.

So, considering two or more cases, this is how I would implement:

var requests = [];
requests.push($http.get('FIRSTRESTURL', {'cache': false}));
requests.push($http.get('SECONDRESTURL', {'cache': false}));

$q.all(requests).then(function (responses) {
  var values = [];
  for (var x in responses) {
    responses[x].success(function(data){
      values.push(data);
    });
  }
  $scope.results = MyService.doCalculation(values);
});

Which, in this case, would force doCalculation to accept an array instead.
