I have created a file into the formData like this:
var fd = new FormData();
fd.append('file', file);
how do i get the content out of the formData? like the filename and the file?
something like this?: fd.filename()
, fd.getData()
.
or fd.get('file')
to retrieve the file back?
There is no way to retrieve the files after you've appended them in to a formData-object I believe.
You'll have to send the formData-object somewhere and then get the files from a req-object or something like that.
In my case (angularJS + nodeJS) I tested this from an answer on SO (link below):
Angular:
var fd = new FormData();
fd.append('file', file);
$http({
method:"POST",
url:"uploadFile",
data: fd,
withCredentials: true,
headers: {'Content-Type': undefined },
transformRequest: angular.identity
});
Node (expressJS):
app.post('/uploadFile', function(req,res){
fs.readFile(req.files.file.path, function(err, data){
// Do something with the data (which holds the file information)
});
});
To see what you can do with the file, read this: http://nodejs.org/api/fs.html
The code is taken from : AngularJS: how to implement a simple file upload with multipart form?
