Hey. I'm new to Kotlin and Ktor. I'm trying to get my uploading function to work but it reads only the first 4096 bytes. I can't figure out what I'm doing wrong and Google doesn't help too.
My code:

val bytes = ByteArrayOutputStream()
val multipart = call.receiveMultipart()
multipart.forEachPart { part ->
     if (part is PartData.FileItem) {
          val stream = part.streamProvider()
          var data = stream.read()
          while (data != -1) {
               bytes.write(data)
               data = stream.read()
         }
         stream.close()
     }
     part.dispose()
}

Hi, @ZargorNET. Thanks for the report. Client or server? Could you provide some additional request information?

[ZargorNET]

It's server side. So basically I want to create an image-uploading service for myself. For that I've added a route

post("/u") {

. In that route I'm asking for an authentication header(just a simple string password) so that just I can upload images:

if (call.request.header("Auth") != configObj.uploadPw) {
                    call.response.status(HttpStatusCode.Unauthorized)
                    call.respondText("""{"error": "unauthorized"}""", ContentType.Application.Json)
                    return@post
                }

And then I'm trying to get all bytes from the uploading images with the method above.

My request is a POST request with the auth header included. The body is "form-data". And in the body I'm creating a field named "file" with the specific image I want to upload

by form-data you mean multipart/form-data?

[ZargorNET]

Yep. Here's the request in text form

POST /u HTTP/1.1
Host: 127.0.0.1:8089
Auth: mypassword
Cache-Control: no-cache
Postman-Token: 9eaafc43-81e9-4620-9136-3dd625a8bfac
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="400px-KeyboardLayout-Danish.png"
Content-Type: image/png
