Multipart upload list files

Question

How I can upload list files from the client with ktor?

I try:

newPostDto.images.map {
    append("images", it)
}

But its variant does not work.

Here's an example (for more information you could check out this repo for a complete image file upload example)

client.submitFormWithBinaryData(
        formData {
            appendInput(key = ICON_FILE_PART, headers = Headers.build {
                append(HttpHeaders.ContentDisposition, "filename=${appId}_ic")
            }) {
                buildPacket { writeFully(icon.toByteArray()) }
            }
        }) {
        apiUrl("$APPLICATIONS_BASE_URL/${appId}/icon")
    }
