获取不到usertoken是怎么回事？

[smc326]

HA错误提示login fail: not exist，对应的是获取不到usertoken。
已通过以下命令，授权第三方应用，并可以看到usertoken，不知道啥原因？
import time import hashlib tick = int(time.time()) appkey = " " callbackurl = "http://localhost" apptoken = " " sdata = "appkey=" + appkey sdata += "&auth_callback=" + callbackurl sdata += "&time=" + str(tick) sdata += "&apptoken=" + apptoken sign = hashlib.md5(sdata.encode(encoding='UTF-8')).hexdigest() url = "https://api.ilifesmart.com/app/auth.authorize?id=001&" url += "&appkey=" + appkey url += "&time=" + str(tick) url += "&auth_callback=" + callbackurl url += "&sign=" + sign url += "&lang=zh" print(url)
