[SOLVED] why this https request only works with urllib3 and requests libraries?

Issue

I'm making this request and it only works with urllib3 and requests library i'm guessing it's because of ssl version or cert verification. any clue would be appreciated

this works

import urllib3

params = {...}
http = urllib3.PoolManager(cert_reqs='CERT_NONE', assert_hostname=False)
r = http.request("POST", "https://android.clients.google.com/auth" , fields=params)
print(r.data)

this return Error=BadAuthentication

from urllib import request, parse
import urllib

params = {...}
data = parse.urlencode(params).encode()
req = request.Request("https://android.clients.google.com/auth", data=data)
try:
  resp = request.urlopen(req)
  print(resp.read())
except urllib.error.HTTPError as e:
  print("error", e.read())

Solution

there was a problem with ciphers using this code worked for me

from urllib import request, parse
import urllib
import ssl

params = {...}

data = parse.urlencode(params).encode()
req = request.Request("https://android.clients.google.com/auth" , data=data) # this will make the method "POST"

DEFAULT_CIPHERS = ':'.join([
    'TLS13-AES-256-GCM-SHA384',
    'TLS13-CHACHA20-POLY1305-SHA256',
    'TLS13-AES-128-GCM-SHA256',
    'ECDH+AESGCM',
    'ECDH+CHACHA20',
    'DH+AESGCM',
    'DH+CHACHA20',
    'ECDH+AES256',
    'DH+AES256',
    'ECDH+AES128',
    'DH+AES',
    'RSA+AESGCM',
    'RSA+AES',
    '!aNULL',
    '!eNULL',
])

ssl_context = ssl.SSLContext()
if getattr(ssl_context, 'supports_set_ciphers', True):  # Platform-specific: Python 2.6
    ssl_context.set_ciphers(DEFAULT_CIPHERS)

try:
  resp = request.urlopen(req, context=ssl_context)
  print(resp.read())
except urllib.error.HTTPError as e:
  print("error", e.read())
