后台服务器是Python写的代码，

wx_c_url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token={}".format(self.access_token)

headers = {'Content-Type': 'application/json;charset=UTF-8'}

resp = requests.post(wx_c_url, data=json.dumps(payload, ensure_ascii=False).encode())

content = resp.json()

errcode = content.get("errcode")

if errcode == 0:

print("create menu bar success !!!!")

else:

errmsg = content.get("errmsg")

print("create menu bar error: {} errcode is: {}".format(errmsg, errcode))

服务器输出的 错误信息是 ：

invalid credential, access_token is invalid or not latest rid: 60473ebc-41c85711-1e2c14d3 errcode is: 40001
