aiohttp

AiohttpSession represents a wrapper-class around ClientSession from aiohttp

Currently AiohttpSession is a default session used in aiogram.Bot

class aiogram.client.session.aiohttp.AiohttpSession(proxy: Iterable[str | Tuple[str, BasicAuth]] | str | Tuple[str, BasicAuth] | None = None, limit: int = 100, **kwargs: Any)[source]

Usage example

from aiogram import Bot
from aiogram.client.session.aiohttp import AiohttpSession

session = AiohttpSession()
bot = Bot('42:token', session=session)

Proxy requests in AiohttpSession

In order to use AiohttpSession with proxy connector you have to install aiohttp-socks

Binding session to bot:

from aiogram import Bot
from aiogram.client.session.aiohttp import AiohttpSession

session = AiohttpSession(proxy="protocol://host:port/")
bot = Bot(token="bot token", session=session)

Note

Only following protocols are supported: http(tunneling), socks4(a), socks5 as aiohttp_socks documentation claims.

Authorization

Proxy authorization credentials can be specified in proxy URL or come as an instance of aiohttp.BasicAuth containing login and password.

Consider examples:

from aiohttp import BasicAuth
from aiogram.client.session.aiohttp import AiohttpSession

auth = BasicAuth(login="user", password="password")
session = AiohttpSession(proxy=("protocol://host:port", auth))

or simply include your basic auth credential in URL

session = AiohttpSession(proxy="protocol://user:password@host:port")

Note

Aiogram prefers BasicAuth over username and password in URL, so if proxy URL contains login and password and BasicAuth object is passed at the same time aiogram will use login and password from BasicAuth instance.

Proxy chains

Since aiohttp-socks supports proxy chains, you’re able to use them in aiogram

Example of chain proxies:

from aiohttp import BasicAuth
from aiogram.client.session.aiohttp import AiohttpSession

auth = BasicAuth(login="user", password="password")
session = AiohttpSession(
    proxy={
        "protocol0://host0:port0",
        "protocol1://user:password@host1:port1",
        ("protocol2://host2:port2", auth),
    }  # can be any iterable if not set
)
