NKN File Transfer
A decentralized file transfer application using NKN client.
This application uses simple control mechanism similar to TCP. If you want to use it in production, it's recommended to implement more advanced mechanism (such as erasure coding) to achieve higher performance and reliability.
You need Go 1.12+ to build from source:
go get -u github.com/nknorg/nkn-file-transfer
Then you can use
go run github.com/nknorg/nkn-file-transfer -$MODE
to run it, where
$MODE can be one of
mode should be used with
receive mode to send file to peer, while
should be used with
host mode to fetch file to peer.
When starting as
receive mode or
host, you will see something like
Start receiver in receive mode at xxx or
Start sender in host mode at xxx, where
xxx will be your NKN address, and you will need that address when sending or
getting files from other peers.
You can enable multiple modes together. For example, you can enable
mode together with
host mode to create a file storage server that can accept
both send request (equivalent to HTTP PUT) and get request (equivalent to HTTP
GET), and you can use
send mode with
get mode to create a client that can
upload to (
send) and download from (
get) the aforementioned server. Actually
if you enable both
send mode and
get mode together, you can use
to download file, and
PUT receiveAddress/fileName localFilePath
to upload file.
There is also a HTTP mode that can be enabled by
-http together with
receive mode. By default it will start a HTTP server at
http://127.0.0.1:8080 and can accept HTTP GET/PUT/HEAD request with route
remoteAddr/fileName. It accepts HTTP GET request with Range header so browser
can stream video while downloading.
By default a random NKN address (key pair) will be generated each time. You can
use a specific address by passing
-identifier argument, same as a
NKN client. Use
-help argument to see all supported arguments.
