我有一個 Lambda 函數，旨在打開/關閉我的 Philip HUE 燈泡。我能夠執行 python 腳本并在我的本地機器上運行（無錯誤）。但是，當我觸發 Lambda 函數（使用 IoT 按鈕）時，我收到以下錯誤消息。[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)我認為該錯誤與以下代碼行有關：internal_dict_value = internal_dict_value.get(k, None)但是，我幾乎可以肯定“internal_dict_value”變量是字典，而不是列表。為了驗證，我將以下代碼行插入到我的腳本中：internal_dict_value = input_dictprint (internal_dict_value)這是我收到的輸出：{ "state": { "on": true, "bri": 254, "hue": 8597, "sat": 121, "effect": "none", "xy": [ 0.4452, 0.4068 ], "ct": 343, "alert": "select", "colormode": "xy", "mode": "homeautomation", "reachable": false }, "swupdate": { "state": "noupdates", "lastinstall": "2019-07-26T19:09:58" }, "type": "Extended color light", "name": "Couch Light", "modelid": "LCT016", "manufacturername": "Philips", "productname": "Hue color lamp", "capabilities": { "certified": true, "control": { "mindimlevel": 1000, "maxlumen": 800, "colorgamuttype": "C", "colorgamut": [ [ 0.6915, 0.3083 ], [ 0.1700, 0.7000 ], [ 0.1532, 0.0475 ] ], "ct": { "min": 153, "max": 500 } }, "streaming": { "renderer": true, "proxy": true } },我腳本的最后一行調用了 lambda_handler() 函數。我被告知我不需要此行，因為我的 Lambda 在觸發 Lambda 函數時調用該函數。但是我（相信）在我的本地機器上執行腳本時，我確實需要手動調用該函數。

在循環期間更改 internal_dict_value 的值的問題是您不知道它將保存什么類型。嘗試類似的東西if type(internal_dict_value) is dict:

這是我的（全功能）python 腳本的最終版本。
import requests,json
bridgeIP = "IP/FQDN_Here:port_here"
userID = "userHash_here"
lightID = "2"
def lambda_handler(event, 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:
if type(internal_dict_value) is dict:
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"])
if bulbStatus == False:
requests.put(f"{url}/state",json.dumps({"on":True}))
elif bulbStatus == True:
requests.put(f"{url}/state",json.dumps({"on":False}))
return {
'statusCode': 200,
'body': json.dumps('Mission accomplished!')
}
