aioftp 0.8.0

ftp client/server for asyncio

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

Features

• Simple.

• Extensible.

• Proxy via twunnel3.

Goals

• 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 (only “I”), 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.

Server benchmark

Compared with pyftpdlib and checked with its ftpbench script.

Getting started

Client example

import asyncio
import aioftp


async def get_mp3(host, port, login, password):
    async with aioftp.ClientSession(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)


loop = asyncio.get_event_loop()
tasks = (
    get_mp3("server1.com", 21, "login", "password")),
    get_mp3("server2.com", 21, "login", "password")),
    get_mp3("server3.com", 21, "login", "password")),
)
loop.run_until_complete(asyncio.wait(tasks))
loop.close()

Server example

import asyncio
import aioftp


loop = asyncio.get_event_loop()
server = aioftp.Server()
loop.run_until_complete(server.start(None, 8021))
try:
    loop.run_forever()
except KeyboardInterrupt:
    server.close()
    loop.run_until_complete(server.wait_closed())
    loop.close()

Or just use simple server

python -m aioftp --help
