Python API Power BI获取令牌但获取请求获取响应401

我已经在Azure中注册了一个应用程序来访问PBI（使用MFA）

应用程序详细信息：

• 本机应用程序（移动桌面）
• API权限
  • Azure Active Directory图表（1）用户。读取
  • Power Bi服务（1）DataSet.ReadWrite.All

我可以获取令牌，但当尝试运行get请求时，我得到错误401

import adal
import requests


authority_url = 'https://login.windows.net/<tennantID>'
resource_url = 'https://analysis.windows.net/powerbi/api'
target_url = 'https://api.powerbi.com/v1.0/myorg/groups/<groupID>/datasets'

client_id = '<applicationID>'
secret= '<clientsecretID>'

context = adal.AuthenticationContext(authority=authority_url,
                                     validate_authority=True,
                                     api_version=None)

token = context.acquire_token_with_client_credentials(resource=resource_url,
                                                     client_id=client_id,
                                                     client_secret=secret)

access_token = token.get('accessToken')

#print(access_token)


header = {'Authorization': f'Bearer {access_token}'}
#print(header)
r = requests.get(url=target_url, headers=header)
r

以下是从python访问powerBI报告数据的步骤

先决条件


一个组织的Active Directory和一个全局管理员
PowerBI Pro许可证（您可以免费获得一个，供试用）
您的广告中同时登录到Power BI的用户

创建应用程序


您需要创建一个应用程序，请遵循以下教程：。确保保存应用程序机密和应用程序id

确保所有权限都正确（请记住，在Azure AD中修改权限时，必须先单击“保存”，然后单击“授予权限”）


确保链接的power bi报告存在并已发布

生成访问令牌


首先，您需要生成一个访问令牌，用于在与API的进一步通信中对自己进行身份验证

端点：
https://login.microsoftonline.com/common/oauth2/token 方法：发布数据：

grant_type: password
scope: openid
resource: https://analysis.windows.net/powerbi/api
client_id: APPLICATION_ID
client_secret: APPLICATION_SECRET
username: USER_ID
password: USER_PASSWORD

用在AAD中创建应用程序后获得的应用程序ID和机密替换应用程序ID，应用程序机密。用主用户的登录名/密码替换用户ID和用户密码。剩下的就这样吧

如果成功，您应获得类似以下内容的响应：

{'access_token': 'eyJ0...ubUA',
 'expires_in': '3599',
 'expires_on': '1515663724',
 'ext_expires_in': '0',
 'id_token': 'eyJ0A...MCJ9.',
 'not_before': '1515659824',
 'refresh_token': 'AQABAA...hsSvCAA',
 'resource': 'https://analysis.windows.net/powerbi/api',
 'scope': 'Capacity.Read.All Capacity.ReadWrite.All Content.Create Dashboard.Read.All Dashboard.ReadWrite.All Data.Alter_Any Dataset.Read.All Dataset.ReadWrite.All Group.Read Group.Read.All Metadata.View_Any Report.Read.All Report.ReadWrite.All Tenant.Read.All Workspace.Read.All Workspace.ReadWrite.All',
 'token_type': 'Bearer'}

一旦获得了令牌，就可以继续进行PowerBIAPI调用了

张贴我使用过的示例代码

这肯定是不对的，如果您为应用程序的服务主体提供了对工作区的访问，那么您不应该需要用户id和密码。这就像是手动登录用户一样。也就是说，它可以工作，但对于服务访问目的来说毫无意义。
