Python 3.x 无法从Azure python函数验证Azure Web App

我已经创建了一个azure python函数，需要从中连接webapp客户端

下面是我的azure python函数代码

import logging
from azure.identity import ManagedIdentityCredential
from azure.mgmt.resource import SubscriptionClient
import azure.functions as func
from azure.mgmt.web import WebSiteManagementClient
from azure.mgmt.web import WebSiteManagementClientConfiguration
from  azure.mgmt.web.models import SiteAuthSettings


def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')
    credentials = ManagedIdentityCredential()
    subscription_client = SubscriptionClient(credentials)
    subscription = next(subscription_client.subscriptions.list())
    subscription_id = subscription.subscription_id

    web_app_client = WebSiteManagementClient(credentials=credentials, subscription_id=subscription_id)

    for i in web_app_client.web_apps.list():
        print ("===================")
        print (i.resource_group)
        print (i.repository_site_name)
        print ("===================")
        get_auth = web_app_client.web_apps.get_auth_settings(i.resource_group, i.repository_site_name)
        if get_auth.enabled == False:
            print ("Auth Method is not enabled on: {} Web APP, Auth method will be enabled!!".format(i.repository_site_name))
            print (get_auth.enabled)
            web_app_client.web_apps.update_auth_settings(i.resource_group, i.repository_site_name, site_auth_settings=SiteAuthSettings(enabled=True, default_provider='AzureActiveDirectory'))
            print ("Auth Method is now enabled on: {} Web APP!!".format(i.repository_site_name))
        else:
            print ("Auth Method is Already enabled on: {} Web App".format(i.repository_site_name))
    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')

    if name:
        return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
    else:
        return func.HttpResponse(
            "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
            status_code=200
        )

当运行代码时，我得到下面的错误

**

看起来你为此打开了一个github问题：-在我看来他们回答了你的问题
