问题描述

通过Azure AD的注册应用获取到Token后，访问AAD Group并查看日志信息时候，遇见了 {"error":{"code":"UnauthorizedAccessException","message":"Attempted to perform an unauthorized operation."}}

Python 代码 -- 使用AAD 注册应用获取Token

import requests
import json

def get_bearer_token():
    tenant_id = "your azure tenant id"
    client_id = "your AAD registrations application id "
    client_secret = "***********************************"

    # The resource (URI) that the bearer token will grant access to
    scope = 'https://api.azrbac.azurepim.identitygovernance.azure.cn/.default'
    # Azure AD authentication endpoint
    AUTHORITY = f'https://login.chinacloudapi.cn/{tenant_id}/oauth2/v2.0/token'
    # Request an access token from Azure AD
    response = requests.post(
        AUTHORITY,
        data={
            'grant_type': 'client_credentials',
            'client_id': client_id,
            'client_secret': client_secret,
            'scope': scope
        }
    )

    if response.status_code == 200:
        access_token = response.json().get('access_token')
    else:
        print("Error occurred while retrieving token:", response.text)
    return access_token

但是，在调用 https://api.azrbac.azurepim.identitygovernance.azure.cn/api/v2/privilegedAccess/aadGroups/activities 接口时候，遇见错误，提示权限不够。

{"error":{"code":"UnauthorizedAccessException","message":"Attempted to perform an unauthorized operation."}}

问题解答

因错误消息提示当前 Access Token无权查看AAD Groups的Activities日志，所以需要进入具体的AAD Groups查看，当前AAD注册应用是否由权限进行任何操作。如无，加入权限后就可以解决问题(PS: 赋予Member 或 Owner权限都可以）

在门户上直接查看的方式：

门户入口：https://portal.azure.cn/#view/Microsoft_Azure_PIMCommon/CommonMenuBlade/~/aadgroup

通过API来列出权限操作列表：

url = "https://api.azrbac.azurepim.identitygovernance.azure.cn/api/v2/privilegedAccess/aadGroups/resources/"+str(aad_groups_list[index]['id'])+"/permissions"

将应用程序加入active assignment后即可获得权限

{'accessLevel': 'AdminRead', 'isActive': True, 'isEligible': False}, {'accessLevel': 'ActivityRead', 'isActive': True, 'isEligible': False}

附录：根据AAD Token获取AAD Group列表和每一个AAD Group的Activity Logs
