申请动态注册获得deviceSecret

import requests
import time
import json

from hashlib import sha256
import hmac


def get_sign(data,key):
    data = data.encode('utf-8')
    key = key.encode('utf-8')
    sign = hmac.new(key, data, digestmod=sha256).hexdigest().lower()
    return sign



timestamp = str(round(time.time() * 1000))
productKey = "cu3dvw7f1ql1lxDa"
productSecret = "59e7cc19d1deb0c8ff7e9648c2e157e2"
deviceKey = "20220217"
signMethod = "hmacsha256"

sign = get_sign(deviceKey + productKey + signMethod + timestamp, productSecret)

url = "https://dmp-https.cuiot.cn:8943/auth/autoregist"


payload = json.dumps({
    "productKey": productKey,
    "productSecret": productSecret,
    "deviceKey": deviceKey,
    "timestamp": timestamp,
    "signMethod": signMethod,
