使用REST API时是否可以使用文件上传的进度条？

Question

I use base64 encoding for file uploads. The REST API is as below for file uploads:

POST /users/:resourceid/files

Authentications are handled through resourceid. And the content of the POST request is files content in base64 format.

Can I have progress bar for my file uploads? If no, then which path should I take to handle file uploads with progress bar?

Answer 1

You can do something like this,

request.upload.addEventListener('progress', function(e){
    _progress.style.width = Math.ceil(e.loaded/e.total) * 100 + '%';
}, false);
