NanoHTTPD 2.0.5 issue with file upload with spaces in filename

Question

I have an android app that uses NanoHTTPD to serve HTML context. I'm using NanoHTTP 2.0.5 in my App.

There's a problem with file uploads. Suppose I upload a file named kr d.mp4; it gets uploaded but renamed to k (starting from one character before space till last char in filename including extension is removed).

Any file upload that has space shows this behaviour. I tried other file name :

 ORIGINAL         GOT THIS
-----------------------------
NO_SPACE.TXT      NO_SPACE.TXT  (works as expected)
ABC DEF.txt       AB
AB1234 gf.txt     AB123
A D.txt           Failed to upload ???

How do I fix this issue ?

Answer 1

I got this working with help from IRC channel #android-dev by user : memoryleak. It was an encoding related issue.

To fix it do this when uploading on :

Client side (Javascript) :

formdata.append("filedata", file, encodeURIComponent(file['name']));

Server Side (NanoHTTPD) :

URLDecoder.decode(session.getParms().get(entry.getKey()), "UTF-8");
