angularjs - Take in-app photo with Cordova Camera and upload it to Parse.com -

-

i'm building ionic/cordova app uses parse.com baas. uses ngcordova camera plugin control device camera. use-case click button, take picture , have upload parse. i've been researching problem week , still can't figure out why can't work.

the controller: 

.controller('cameractrl', function($scope, camera) {  var cameraoptions = { quality: 75, destinationtype: 0, encodingtype: 0, targetwidth: 300, targetheight: 300, mediatype: 0, correctorientation: true, savetophotoalbum: true };     };      $scope.takepicture = function() {         cameraoptions.sourcetype = 1;         navigator.camera.getpicture(onsuccess, onfail, cameraoptions);     }      $scope.selectpicture = function() {         cameraoptions.sourcetype = 0;         navigator.camera.getpicture(onsuccess, onfail, cameraoptions);     }      function onsuccess(picture) {          file.upload(picture)             .success(function(data) {                 // upload finish             });          $scope.$apply(function() {             $scope.preview = 'data:image/jpeg;base64,' + picture;         });     }      function onfail(resp) {         alert('error: ' + resp);     }  });

the service: 

angular.factory('file', function ($http) { return {     upload: function (photo) {          var json = {             'base64': photo,             '_contenttype': 'image/jpeg'         }          var config = {             method: 'post',             url: 'https://api.parse.com/1/files/pict.jpg',             data: json,             headers: {                 'x-parse-application-id': 'pcm0kdvethvrcdfus9litrmskehqjbqwfaydl2lr',                 'x-parse-rest-api-key': 'fhasgktl0blpjulljvpb2nfwlccxzvbirktdngxn'             }         };          return $http(config);     } } });

the html: 

<button class="button" ng-click="takepicture()">

any ideas why doesn't work? there better or more simple way accomplish this? examples of working somewhere? i've tried dozen different solutions on week , haven't found works use-case. thanks!

        var imagefile = new parse.file("mypic.jpg", {base64: _params.photo});         console.log(imagefile);          // save parse file         return imagefile.save().then(function () {              // create object hold caption , file reference             var imageobject = new imageobject();              // set object properties             imageobject.set("caption", _params.caption);             imageobject.set("picture", imagefile);              // save object parse backend             return imageobject.save();           }, function (error) {             console.log("error");             console.log(error);         });
