python - AWS Lambda 错误：AttributeError 'list' 对象没有属性 'get'

问题描述

我有一个 Lambda 函数，旨在打开/关闭我的 Philip HUE 灯泡。我能够执行 python 脚本并在我的本地机器上运行（无错误）。但是，当我触发 Lambda 函数（使用 IoT 按钮）时，我收到以下错误消息。

[ERROR] AttributeError: 'list' object has no attribute 'get'
Traceback (most recent call last):
  File "/var/task/lambda_function.py", line 21, in lambda_handler
    bulbStatus = nested_get(data,["state","on"])
  File "/var/task/lambda_function.py", line 16, in nestedDictLookup
    internal_dict_value = internal_dict_value.get(k, None)

我认为该错误与以下代码行有关：

internal_dict_value = internal_dict_value.get(k, None)

但是，我几乎可以肯定“internal_dict_value”变量是字典，而不是列表。为了验证，我将以下代码行插入到我的脚本中：

internal_dict_value = input_dict
print (internal_dict_value)

这是我收到的输出：

这是我正在使用的脚本。如果您有任何鼓舞人心的想法，请分享！谢谢。

import requests,json

bridgeIP = "IP_Address_Here"
userID = "userID_here"
lightID = "4" #Represents the ID assigned to lightbulb, in the living room.

def lambda_handler(lightID, lambda_context):
    url = f"http://{bridgeIP}/api/{userID}/lights/{lightID}"

    r = requests.get(url)
    data = json.loads(r.text)

    def nested_get(input_dict, nested_key):
        internal_dict_value = input_dict
        for k in nested_key:
            internal_dict_value = internal_dict_value.get(k, None)
            if internal_dict_value is None:
                return None
        return internal_dict_value


    bulbStatus = nested_get(data,{"state","on"})
    #the nested_get() function captures the dict value, assigned to the "on" key.
    #{"state":{"on":{True}} or {"state":{"on":{False}}

    if bulbStatus == False:
        r = requests.put(f"{url}/state", json.dumps({"on":True}))
    elif bulbStatus == True:
        r = requests.put(f"{url}/state", json.dumps({"on":False}))

lambda_handler(lightID, 4)

我脚本的最后一行调用了 lambda_handler() 函数。我被告知我不需要此行，因为我的 Lambda 在触发 Lambda 函数时调用该函数。但是我（相信）在我的本地机器上执行脚本时，我确实需要手动调用该函数。
