<html>
   <head>
      <script src = "https://ajax.googleapis.com/ajax/pbs/angularjs/1.3.14/angular.min.js">
      </script>
   </head>
   
   <body ng-app = "myApp">
	
      <span ng-controller = "myCtrl">
         <input type = "file" file-model = "myFile"/>
         <button ng-cpck = "uploadFile()">upload me</button>
      </span>
      
      <script>
         var myApp = angular.module( myApp , []);
         
         myApp.directive( fileModel , [ $parse , function ($parse) {
            return {
               restrict:  A ,
               pnk: function(scope, element, attrs) {
                  var model = $parse(attrs.fileModel);
                  var modelSetter = model.assign;
                  
                  element.bind( change , function() {
                     scope.$apply(function() {
                        modelSetter(scope, element[0].files[0]);
                     });
                  });
               }
            };
         }]);
         myApp.service( fileUpload , [ $https: , function ($https:) {
            this.uploadFileToUrl = function(file, uploadUrl) {
               var fd = new FormData();
               fd.append( file , file);
            
               $https:.post(uploadUrl, fd, {
                  transformRequest: angular.identity,
                  headers: { Content-Type : undefined}
               })
               .success(function() {
               })
               .error(function() {
               });
            }
         }]);
         myApp.controller( myCtrl , [ $scope ,  fileUpload , function($scope, fileUpload) {
            $scope.uploadFile = function() {
               
               var file = $scope.myFile;
               console.log( file is   );
               console.dir(file);
               var uploadUrl = "/fileUpload";
               fileUpload.uploadFileToUrl(file, uploadUrl);
            };
         }]);
      </script>
