I am trying to upload a photo from mobile device to azure blob storage. I just can’t seem to get it to work.
window.resolveLocalFileSystemURL(file, function (fileEntry) //doesn’t work
var reader = new FileReader(); //this doesn’t work either
reader.onloadend = readCompleted; //onloadend doesn’t seem to get called either.
I’ve been fighting with this for last 4 days. I don’t know if this is Cordova issue or Ionic or me.
Ionic Version is 1.6.1
cordova version is 5.1.1
/Cordova Camera API calls/
$scope.takePic = function (type) {
if (navigator.camera != undefined) {
if (type == 'PHOTOLIBRARY')
type = Camera.PictureSourceType.PHOTOLIBRARY;
else if (type == 'CAMERA')
type = Camera.PictureSourceType.CAMERA;
var options = {
quality: 45,
destinationType: Camera.DestinationType.DATA_URL,
sourceType: type,
allowEdit: true,
encodingType: Camera.EncodingType.JPEG,
saveToPhotoAlbum: false
}
navigator.camera.getPicture(onSuccess, onFail, options);
}
}
$scope.message = “Add an image”;
var onSuccess = function (DATA_URL) {
$scope.message = “Choose another image”;
$scope.postForm.onFileSelect = DATA_URL;
$scope.$apply();
};
var onFail = function (e) {
$scope.picData = null;
$scope.message = "On fail " + e;
};
var reader = new FileReader();
//$scope.blobSasUrl is url to upload to azure blob storage
reader.onloadend = function (evt) {
$(’#fileContents’).html(e.target.result);
reader.readAsDataURL(file);
fileReader.onload = function (e) {
file = e.target.result;
//navigator.notification.alert(file, null, 'file2');
var ajaxRequest = new XMLHttpRequest();
try {
// Performing an PutBlob (BlockBlob) against storage
ajaxRequest.open('PUT', blobSasUrl, true);
ajaxRequest.setRequestHeader('Content-Type', 'image/jpeg');
ajaxRequest.setRequestHeader('x-ms-blob-type', 'BlockBlob');
ajaxRequest.send(file);
navigator.notification.alert('uploaded', null, 'requestData');
}
catch (e) {
console.warn("can't upload the image to server.\n" + e.toString());
}
}
};
and so on…
