# Aiohttp session
|
|
|
|
AiohttpSession represents a wrapper-class around `ClientSession` from [aiohttp]('https://pypi.org/project/aiohttp/')
|
|
|
|
Currently `AiohttpSession` is a default session used in `aiogram.Bot`
|
|
|
|
## Usage example
|
|
|
|
```python
|
|
from aiogram import Bot
|
|
from aiogram.api.client.session.aiohttp import AiohttpSession
|
|
|
|
session = AiohttpSession()
|
|
Bot('token', session=session)
|
|
```
|
|
|
|
|
|
## Proxy requests in AiohttpSession
|
|
|
|
In order to use AiohttpSession with proxy connector you have to install [aiohttp-socks]('https://pypi.org/project/aiohttp-socks/')
|
|
|
|
Binding session to bot:
|
|
```python
|
|
from aiogram import Bot
|
|
from aiogram.api.client.session.aiohttp import AiohttpSession
|
|
|
|
session = AiohttpSession(proxy="protocol://host:port/")
|
|
Bot(token="bot token", session=session)
|
|
```
|
|
|
|
!!! note "Protocols"
|
|
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:
|
|
```python
|
|
from aiohttp import BasicAuth
|
|
from aiogram.api.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 "Credential priorities"
|
|
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]('https://pypi.org/project/aiohttp-socks/') supports proxy chains, you're able to use them in aiogram
|
|
|
|
Example of chain proxies:
|
|
```python
|
|
from aiohttp import BasicAuth
|
|
from aiogram.api.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
|
|
)
|
|
```
|
|
|
|
