It reads the passed NetworkReadStream and prints its contents onto console (for now). It would be writing contents into file. To simplify work with raw NetworkReadStream there is a new CurlRequest. It basically does nothing, but as ConnMan handles transfers only if there is an active Request, you need some Request to get NetworkReadStream working. Thus, there is a CurlRequest, which is active until NetworkReadStream is completely read. CurlRequest also has useful addHeader() and addPostField() methods in order to customize the request easily. Use execute() method to get its NetworkReadStream. DropboxStorage implements streamFile() and download() API methods. As DownloadRequest is incomplete, it is not actually downloading a file, though.
