# 示例2: https://www.caorui.net/blog/38.html 中的钉钉加签python3代码示例
import hmac
import hashlib
import base64
import re
import time
import urllib

# secret：密钥，机器人安全设置页面，加签一栏下面显示的SEC开头的字符串，例如：SECxxxxxxxx
secret = 'SECxxx'
# timestamp：当前时间戳，单位是毫秒，与请求调用时间误差不能超过1小时
timestamp = int(round(time.time() * 1000))
# 加密，获取sign和timestamp
data = (str(timestamp) + '\n' + secret).encode('utf-8')
secret = secret.encode('utf-8')
# 使用HmacSHA256算法计算签名，然后进行Base64 encode
signature = base64.b64encode(hmac.new(secret, data, digestmod=hashlib.sha256).digest())
reg = re.compile(r"'(.*)'")
signature = str(re.findall(reg, str(signature))[0])
# 最后进行urlEncode
urlencode = urllib.parse.quote_plus(signature)
print(timestamp)
print(urlencode)
