using ng-file-upload to upload file to hard drive - angularjs

Question

I want to use ng-file-upload to upload files to hard drive in the server
this.uploadFiles = function(files, errFiles) {
this.files = files;
this.errFiles = errFiles;
angular.forEach(files, function(file) {
file.upload = Upload.upload({
url: 'C:\Java\logs',
data: {file: file}
});
file.upload.then(function (response) {
$timeout(function () {
file.result = response.data;
});
}, function (response) {
if (response.status > 0)
this.errorMsg = response.status + ': ' + response.data;
}, function (evt) {
file.progress = Math.min(100, parseInt(100.0 *
evt.loaded / evt.total));
});
});
}
when I use this code I get this error
angular.js:10765 XMLHttpRequest cannot load file:///C:/Javalogs. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.
that what I did but it didn't work
this.uploadFiles = function(file, errFiles) {
Upload.dataUrl(file[0], true).then(function (base64Url) {
var filename = 'test.jpg';
var a = document.createElement("a");
var myDocument = getFileContainer(base64Url);
var blob = new Blob([myDocument.data], {type: 'image/jpg'});
var file = new File([blob], 'imageFileName.jpg');
if(window.navigator.msSaveOrOpenBlob) {
window.navigator.msSaveBlob(blob, filename);
}
else{
var elem = window.document.createElement('a');
elem.href = window.URL.createObjectURL(file);
elem.download = filename;
document.body.appendChild(elem);
elem.click();
document.body.removeChild(elem);
}
})
the picture is generated but I can't view it

I send them via a base64 url to the backend. It depends on which data you need but it should roughly look like the following code.
function getMimeTypeFromUrl(imageUrl) {
return imageUrl.substring(imageUrl.indexOf(':') + 1, imageUrl.indexOf(';'));
}
function getDataFromUrl(imageUrl){
return imageUrl.substring(imageUrl.indexOf(',') + 1);
}
function getFileContainer(imageUrl, file){
return {
data:getDataFromUrl(imageUrl),
mimeType: getMimeTypeFromUrl(imageUrl),
filename: file.name,
}
}
this.uploadFiles = function(files, errFiles) {
Upload.dataUrl(file, true).then(function (base64Url) {
myDocument = getFileContainer(base64Url, file);
//here you have to post myDocument
}
}
Upload is a service of ng-file-upload, which loads the file to the browser as a base64 url.
I hope I could help you.
