Azure Function App 错误：AttributeError：“str”对象在从字典中提取数据时没有属性“get”-解网

问：

我开发的函数应用突然出现错误，我使用 .get（）方法从字典中提取数据。下面是我使用的示例代码：

def sendOpenAIPromptRequest(azureopenai_endpoint, azureopenai_deployment,azureopenai_token, azureopenai_version, workItemDetails):
    workItemSummary = []

    #Iteration per object in workItemDetails
    for item in workItemDetails:
        openai_prompt = openAIPrompt(item)
        try:
            url =  f"{azureopenai_endpoint}/openai/deployments/{azureopenai_deployment}/chat/completions?{azureopenai_version}"
            headers = {
                        "Content-Type": "application/json",
                        "Authorization": f"Bearer {azureopenai_token}"
                        }
            body = {
                                "max_tokens": 590,
                                "messages": [
                                    {
                                        "role": "user", 
                                        "content": openai_prompt
                                    }
                                ],
                                "temperature": 0.25
                    }
            response = requests.post(url=url, headers=headers, json=body)
            print(response)
            responseContent = json.loads(response.text)
            
        except:
            return print("An error has occurred.")
        container = {
            "UserStoryId": item.get("UserStoryId", ""),
            "UserStoryTitle": item.get("UserStoryTitle", ""),
            "UserStoryState":item.get("UserStoryState", ""),
            "UserStoryType": item.get("UserStoryType", ""),
            "Summary": responseContent['choices'][0]['message']['content']
        }
        
        workItemSummary.append(container)
    
    return json.dumps({"workItemSummaryValue": workItemSummary})

workItemDetails 是一个字典列表，我需要在其中将其数据传输到“容器”变量。

workItemDetails = [
{
            "UserStoryId": "id1",
            "UserStoryTitle": "title1",
            "UserStoryState": "state1",
            "UserStoryType": "type1"
            "RawUpdates": "updates1",
            "RawComments": "comments1"
        },
{
            "UserStoryId": "id2",
            "UserStoryTitle": "title2",
            "UserStoryState": "state2",
            "UserStoryType": "type2"
            "RawUpdates": "updates2",
            "RawComments": "comments2"
        }]

在过去的几周里，它运行良好，但是当我从VScode或已部署的应用程序再次运行它时，它将返回此错误：

[2023-11-09T23:41:43.106Z] Executed 'Functions.MyFunctionApp' (Failed, Id=d91f7dc1-8c42-477d-a506-6128fd5e6898, Duration=10120ms) [2023-11-09T23:41:43.109Z] System.Private.CoreLib: Exception while executing function: Functions.MyFunctionApp. System.Private.CoreLib: Result: Failure Exception: AttributeError: 'str' object has no attribute 'get'

请帮我解决这个问题。

我需要将数据从字典传输到 Azure 函数应用中的另一个字典变量。

python 字典调试 azure-functions

workItemDetails = [ {             "UserStoryId": "id1",             "UserStoryTitle": "title1",             "UserStoryState": "state1",             "UserStoryType": "type1"             "RawUpdates": "updates1",             "RawComments": "comments1"         }, {             "UserStoryId": "id2",             "UserStoryTitle": "title2",             "UserStoryState": "state2",             "UserStoryType": "type2"             "RawUpdates": "updates2",             "RawComments": "comments2"         }]

我编辑了我的帖子以显示workItemDetail数据

是的。我的代码在本地 Python 文件中工作。但是，当我在终端中使用“func start”命令通过 Azure 函数应用运行它时，它将返回错误。

workItemDetails 是一个字典列表你确定吗？作为调试步骤，请尝试在循环顶部进行打印。item

您可以通过以下方式检查数据类型：

for item in workItemDetails:
  print(type(item))

我假设你是这样的：workItemDetails

workItemDetails = ['{ "UserStoryId": "id1","UserStoryTitle": "title1","UserStoryState": "state1", "UserStoryType": "type1","RawUpdates": "updates1","RawComments": "comments1"}',
'{"UserStoryId": "id2","UserStoryTitle": "title2","UserStoryState": "state2","UserStoryType": "type2","RawUpdates": "updates2","RawComments": "comments2"}']

现在，如果您这样做：

for item in workItemDetails:
  container = {
            "UserStoryId": item.get("UserStoryId", ""),
            "UserStoryTitle": item.get("UserStoryTitle", ""),
            "UserStoryState":item.get("UserStoryState", ""),
            "UserStoryType": item.get("UserStoryType", ""),
            
        }

您将收到以下错误：

AttributeError                            Traceback (most recent call last)
<ipython-input-12-a611593be7a6> in <cell line: 1>()
      1 for item in workItemDetails:
      2   container = {
----> 3             "UserStoryId": item.get("UserStoryId", ""),
      4             "UserStoryTitle": item.get("UserStoryTitle", ""),
      5             "UserStoryState":item.get("UserStoryState", ""),

AttributeError: 'str' object has no attribute 'get'

解决方法：

from ast import literal_eval
workItemDetails = [literal_eval(item) for item in workItemDetails]

for item in workItemDetails:
    container = {
            "UserStoryId": item.get("UserStoryId", ""),
            "UserStoryTitle": item.get("UserStoryTitle", ""),
            "UserStoryState":item.get("UserStoryState", ""),
            "UserStoryType": item.get("UserStoryType", ""),
            
        }

print(container)

{'UserStoryId': 'id2',
 'UserStoryTitle': 'title2',
 'UserStoryState': 'state2',
 'UserStoryType': 'type2'}

上一个：VScode 无法识别我的 launch.json 参数，我该如何解决这个问题？

下一个：如何在Visual Studio调用堆栈中读取匿名lambda的名称？
