javascript - Send image from filesystem to server in AngularJs -

i need send in background multiple-image , data server.

i'm using ionicframework (with angularjs) android app. i'm using angular-file-upload (directive) , following code factory:

if(angular.isarray(arrpictures) && arrpictures.length > 0) {         var files = [];        for(var i=0; i<arrpictures.length; i++) {            files.push(arrpictures[i].photo); //it file://my_path/myimage.jpg        }          $upload.upload({             url: api_post_answer,             method: 'post',             data: {                 "idsurvey": idsurvey,                 "idoam": idoam,                 "idopm": idopm,                 "score": score,                 "date": date,                 "answerjson": answersjson,                 "address": address,                 "latitude": latitude,                 "longitude": longitude             },             file: files,             fileformdataname: "pictures"         }).progress(function (evt) {             //progress             alert('progress: ' + parseint(100.0 * evt.loaded / evt.total) + '% file :'+ evt.config.file.name);         }).success(function (data, status, headers, config) {             // file uploaded             alert('file ' + config.file.name + 'is uploaded successfully. response: ' + data);         }).error(function (ex) {             //error             alert("error");             alert(ex);         });     }  

now have problem because server strings (path string) , not files question "how can convert path string file object send currectly server?"

my solution convert image base64 , store local db (using sqllite). after when want send image: query db, base64 string , send rest services.

all solution whitout using $upload directive $http service.
