Question

Here is my HTML form:

Answer 1

The easiest is to use HTML5 API, namely FileReader

HTML is pretty straightforward:

Add

In your controller define 'add' method:

$scope.add = function() {
    var f = document.getElementById('file').files[0],
        r = new FileReader();

    r.onloadend = function(e) {
      var data = e.target.result;
      //send your binary data via $http or $resource or do anything else with it
    }

    r.readAsBinaryString(f);
}
