import time

import urllib.parse
from dingtalkchatbot.chatbot import DingtalkChatbot

timestamp = str(round(time.time() * 1000))

robot_webhook = "" # 机器人的 webhook
secret = ""  # 替换成你的签

secret_enc = secret.encode("utf-8")
string_to_sign = "{}\n{}".format(timestamp, 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))

webhook = f"{robot_webhook}&timestamp={timestamp}&sign={sign}"

msg_text = "" # 你要发送的消息内容

msgs = DingtalkChatbot(webhook)

'''
at_mobiles: 被@的人的手机号 eg: ['138xxxxxxxx', '136xxxxxxxx']
is_at_all : 是否 @ 全员

states = msgs.send_text(msg=(msg_text), at_mobiles=[], is_at_all=False)

print(f"钉钉机器人消息状态: {states}")
