关于urllib在python2和python3中的验签差异

在python2中

import urllib

def compute_sign(ding_secret):
    timestamp = str(int(round(time.time() * 1000)))
    secret_enc = ding_secret.encode('utf-8')
    string_to_sign = '{}\n{}'.format(timestamp, ding_secret)
    string_to_sign_enc = string_to_sign.encode('utf-8')
    hmac_code = hmac.new(secret_enc, string_to_sign_enc, digestmod=hashlib.sha256).digest()
    sign = urllib.quote(base64.b64encode(hmac_code))
    return [timestamp, sign]

 

在python3中

import urllib.parse

def compute_sign(ding_secret):
    timestamp = str(round(time.time() * 1000))
    secret_enc = ding_secret.encode('utf-8')
    string_to_sign = '{}\n{}'.format(timestamp, ding_secret)
    string_to_sign_enc = string_to_sign.encode('utf-8')
    hmac_code = hmac.new(secret_enc, string_to_sign_enc, digestmod=hashlib.sha256).digest()
    sign = urllib.parse.quote_plus(base64.b64encode(hmac_code))
    return [timestamp, sign]
