python - Instancemethod 对象不可迭代 (AirPi) (Python)

Question

在调试来自 https://github.com/haydnw/AirPi/blob/master/outputs/ubidots.py 的 AirPi 代码时，我遇到了输出期间出现异常:“instancemethod”对象不可迭代

这假设将我的传感器数据上传到 Ubidots 服务器。

*我将正确的 token 和变量 ID 放入此 AirPi 的配置文件中。

requiredSpecificParams = ["token"]
optionalSpecificParams = ["showcost",
                  "ID-BMP085-temp",
                  "ID-BMP085-pres",
                  "ID-DHT22-hum",
                  "ID-DHT22-temp",
                  "ID-LDR",
                  "ID-TGS2600",
                  "ID-MiCS-2710",
                  "ID-MiCS-5525",
                  "ID-Microphone",
                  "ID-Raingauge"
                  ]

def __init__(self, config):
    super(Ubidots, self).__init__(config)        
    self.token = self.params["token"]
    if "showcost" in self.params:
        self.showcost = self.params["showcost"]
    else:
        self.showcost = False
    self.ubivariables = {}
    for key, value in self.params.iteritems():
        if key[:3] == "ID-":
            if value:
                self.ubivariables[key[3:]] = value

def output_data(self, datapoints, dummy):
    """Output data.

for response in req.json:

根据the documentation , json 是一个方法，必须调用，所以应该是:

for response in req.json():

将来，包含重现问题所需的尽可能多的代码以及包含带有回溯的完整错误消息会很有帮助。
