Question

我得到错误：输出时出现异常：从https://github.com/haydnw/AirPi/blob/master/outputs/ubidots.py调试此AirPi代码时，'instancemethod'对象无法迭代

这假设将我的传感器数据上传到Ubidots服务器。

*我将正确的令牌和变量ID放在此AirPi的配置文件中。

requiredSpecificParams = ["token"]
optionalSpecificParams = ["showcost",
                  "ID-BMP085-temp",

for response in req.json:

根据the documentation，json是一种方法，必须调用，所以这应该是：

for response in req.json():

将来，尽可能多地包含重现问题所需的代码，并包含带有回溯的完整错误消息是很有帮助的。
