ftp client/server for asyncio (http://aioftp.readthedocs.org)

• Simple.
• Extensible.
• Client socks proxy via siosocks (pip install aioftp[socks]).

• Minimum usable core.
• Do not use deprecated or overridden commands and features (if possible).
• Very high level api.

Client use this commands: USER, PASS, ACCT, PWD, CWD, CDUP, MKD, RMD, MLSD, MLST, RNFR, RNTO, DELE, STOR, APPE, RETR, TYPE, PASV, ABOR, QUIT, REST, LIST (as fallback)

Server support this commands: USER, PASS, QUIT, PWD, CWD, CDUP, MKD, RMD, MLSD, LIST (but it's not recommended to use it, cause it has no standard format), MLST, RNFR, RNTO, DELE, STOR, RETR, TYPE ("I" and "A"), PASV, ABOR, APPE, REST

This subsets are enough for 99% of tasks, but if you need something, then you can easily extend current set of commands.

Compared with pyftpdlib and checked with its ftpbench script.

Client example

WARNING

For all commands, which use some sort of «stats» or «listing», aioftp tries at first MLSx-family commands (since they have structured, machine readable format for all platforms). But old/lazy/nasty servers do not implement this commands. In this case aioftp tries a LIST command, which have no standard format and can not be parsed in all cases. Take a look at FileZilla «directory listing» parser code. So, before creating new issue be sure this is not your case (you can check it with logs). Anyway, you can provide your own LIST parser routine (see the client documentation).

import asyncio
import aioftp


async def get_mp3(host, port, login, password):
    async with aioftp.Client.context(host, port, login, password) as client:
        for path, info in (await client.list(recursive=True)):
            if info["type"] == "file" and path.suffix == ".mp3":
                await client.download(path)


async def main():
    tasks = [
        asyncio.create_task(get_mp3("server1.com", 21, "login", "password")),
        asyncio.create_task(get_mp3("server2.com", 21, "login", "password")),
        asyncio.create_task(get_mp3("server3.com", 21, "login", "password")),
    ]
    await asyncio.wait(tasks)

asyncio.run(main())

Server example

import asyncio
import aioftp


async def main():
    server = aioftp.Server([user], path_io_factory=path_io_factory)
    await server.run()

asyncio.run(main())

Or just use simple server

python -m aioftp --help
