DoH example

DoT example:

import dns.message

import dns.name

import dns.query

qname = dns.name.from_text('dns.google.')

q = dns.message.make_query(qname, dns.rdatatype.A)

response = dns.query.tls(q, '8.8.8.8')

print(response)

Hey

I have a new issue while running the DoH Example inside docker

Traceback (most recent call last):
File "temp.py", line 42, in <module>
    main()
File "temp.py", line 21, in main
    r = dns.query.https(q, where, session=session)
File "/usr/local/lib/python3.8/dist-packages/dns/query.py", line 278, in https
    raise NoDOH # pragma: no cover
dns.query.NoDOH: DNS over HTTPS (DOH) was requested but the requests module is not
    available.

But I have requests module installed and up-to-date.

How can I fix this

That exception means that one of the requirements could not be imported. dnspython needs both requests and requests-toolbelt. Maybe you're missing the latter?

If you're installing dnspython with pip, you can say

pip install dnspython[doh]

to install dnspython and all the requirements for DoH.

DoT uses python's ssl module, so no extra requirements.
