DNS over HTTPS based on aiohttp and async_dns.
$ pip install async-dohusage: python3 -m async_doh.client [-h] [-n NAMESERVERS [NAMESERVERS ...]] [-t TYPES [TYPES ...]] hostnames [hostnames ...]
Async DNS resolver with DoH
positional arguments:
hostnames the hostnames to query
optional arguments:
-h, --help show this help message and exit
-n NAMESERVERS [NAMESERVERS ...], --nameservers NAMESERVERS [NAMESERVERS ...]
name servers
-t TYPES [TYPES ...], --types TYPES [TYPES ...]
query types, default as `any`
Examples:
$ python3 -m async_doh.client -n https://223.5.5.5/dns-query -t ANY -- www.google.comimport asyncio
import aiohttp
from async_doh.client import DoHClient
async def main():
async with DoHClient() as client:
result = await client.query('https://1.1.1.1/dns-query', 'www.google.com', 'A')
print('query:', result)
result = await client.query_json('https://1.1.1.1/dns-query', 'www.google.com', 'A')
print('query_json:', result)
asyncio.run(main())from aiohttp import web
from async_doh.server import application
web.run(application)Now you have http://localhost:8080/dns-query as an endpoint.
By importing the patch, async_dns will use aiohttp to send queries through HTTPS (aka DNS over HTTPS):
import asyncio
from async_dns.core import types
from async_dns.resolver import ProxyResolver
from async_doh.client import patch
async def main():
revoke = await patch()
resolver = ProxyResolver(proxies=['https://dns.alidns.com/dns-query'])
res, _ = await resolver.query('www.google.com', types.A)
print(res)
await revoke()
asyncio.run(main())
