I'm using HTML5 file API to upload files to my web application.
I have an input element on my web page using which I read files and call upload function
<input type="file">
$('input[type="file"]').on("change",function(e){
console.log(this.files);
// upload each file in this.files
});
This works perfectly for native files on os. I want to now upload remote files eg, example.com/blah/file1.jpg My question is how do I read this file using File API? Is there a way to do it?
You can download remote files over XMLHttpRequest
, and process them as Blob
. Then upload it to another server. The upload has to be over XMLHttpRequest
. It relies on the browser's implementation of XHR Level 2. This link contains the code snippets you will need:

It has both snippets for downloading remote file as a Blob
and uploading a Blob
to a server.
