i am creating simple file upload module in Angular js(v1.3.4). I am using Nodejs server side. I am using https://github.com/danialfarid/angular-file-upload library. It looks pretty straight forward but i am stuck at the basic step.
index.html
<div ng-controller="FileUploadController">
<input type="file" ng-file-select="onFileSelect($files)" multiple>
</div>
controller.js
$scope.onFileSelect = function($files) {
for (var i = 0; i < $files.length; i++) {
var file = $files[i];
$scope.upload = $upload.upload({
url: 'http://localhost:8080/file-transfer/123/upload',
// headers: {'Content-Type': undefined},
// withCredentials: true,
// transformRequest: angular.identity,
file: file
}).progress(function(evt) {
console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
}).success(function(data, status, headers, config) {
// file is uploaded successfully
console.log(data);
});
}
On Server side, I am using multer
for multipart . client is sending the request to server but not sending the file data.
app.all('/file-transfer/:id/upload', function (req, res) {
res.header('Access-Control-Allow-Credentials', true);
res.header('Access-Control-Allow-Origin', req.headers.origin);
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header('Access-Control-Allow-Headers', 'X-Requested-With, X-HTTP-Method-Override, Content-Type, Accept');
console.log(req.body); // prints - {}
console.log(req.files); // prints - {}
});
Request Header -
Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding gzip, deflate
Accept-Language en-US,en;q=0.5
Access-Control-Request-Me... POST
Cache-Control no-cache
Connection keep-alive
Host localhost:8080
Origin http://localhost
Pragma no-cache
User-Agent Mozilla/5.0 (Windows NT 6.2; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0
I used the same code as in example of repository.Maybe i am missing something.
Note - Server codes working fine when i use simple html 5 form without angular or if i use $http.post.
EDIT : It was CORS problem, Read the comments of answer.
I'm using same library, the only thing different in my client side code is I have the method: 'POST'
header being sent:
$scope.upload = $upload.upload({
url: '/api/uploads', //upload.php script, node.js route, or servlet url
// method: 'POST' or 'PUT',
method: 'POST',
// headers: {'header-key': 'header-value'},
// withCredentials: true,
data: { type: 'profileImage' },
file: file//, // or list of files: $files for html5 only
// fileName: 'doc.jpg' or ['1.jpg', '2.jpg', ...] // to modify the name of the file
/* customize file formData name ('Content-Desposition'), server side file variable name.
Default is 'file' */
//fileFormDataName: myFile, //or a list of names for multiple files (html5).
/* customize how data is added to formData. See #40#issuecomment-28612000 for sample code */
//formDataAppender: function(formData, key, val){}
}).progress(function (e) {
console.log('percent: ' + parseInt(100.0 * e.loaded / e.total));
}).success(function (data, status, headers, config) {
// file is uploaded successfully
console.log(data);
$scope.user.profileImages = data;
$rootScope.$emit('message', { text: "Your profile image has been updated." });
}).error(function(data){
if ( data.error === 'UnsupportedFiletype' ) {
$rootScope.$emit('message', { type: 'error', text: "Woops, we don't support that filetype." });
}
});
Edit: The solution was to just properly serve a cors header:
npm install cors
and app.use(cors())
.
