Python 不记名令牌写访问问题的 ADAL

ADAL for Python bearer token write access issue

https://github.com/Azure-Samples/ms-identity-python-webapp 中使用此配置对我有用。范围必须包括 CDS organization/environment API URL.

ADAL 问题 Pyhton 不记名令牌问题

我正在使用与 Common Data Service 交互的 REST 应用程序的客户端 ID 和机密进行非交互身份验证。首先在 Postman 中进行测试,我能够使用我的凭据成功执行读取和写入操作。

在 Python 中实现 REST API 时,我只能通过版本 adal==1.2.2Azure AD Authentication Library (ADAL) 执行读取操作。我通过配置文件在 Python 中的 Postman 环境中使用相同的凭据,下面是一个示例。我还在 Postman 中测试了这个 Python ADAL 生成的令牌,以验证我是否可以发出获取请求,因为我注意到令牌字符串在我在 Python 中生成的和我在 Postman 中生成的字符串之间是不同的。发出 post 请求时,我收到下面进一步显示的错误。我的猜测是我需要 python 中的逻辑以某种方式告诉 ADAL 允许请求令牌的用户写入权限。

代码和 Postman 错误

import adal

from .config import *

class AzureAuth:
    bearerToken = ""

    def __init__(self):
        authCtx = adal.AuthenticationContext(AUTHORITY_URL)
        tokenResponse = authCtx.acquire_token_with_client_credentials(RESOURCE, CLIENT_ID, CLIENT_SECRET)
        self.bearerToken = tokenResponse["accessToken"]

这是我的 config.py 的示例。

AUTHORITY_URL=""
CDS_API_URL=""
CLIENT_ID=""
CLIENT_SECRET=""
REDIRECT_URI=""
RESOURCE="" # like "https://your_cds_environment.api.crm.dynamics.com/"
TENANT="" # like "https://login.microsoftonline.com/put_your_tenant"

当我将 Python 令牌复制粘贴到 Postman post 请求时,Postman 抛出错误。

这些是我在请求令牌时在 Postman 中归档的字段以及这些字段的值,为了安全我删除了密码。

这些是我的应用使用的权限。

根据您提供的代码和图片,在postman中,您使用OAuth 2.0 code grant flow to require Azure AD access token. The way is getting access on behalf of a user. The token is user token. But in your application, you use the method acquire_token_with_client_credentials to require Azure AD access token. It means that you use OAuth 2.0 Client Credentials Grant Flow请求Azure AD访问令牌。方法是在没有用户的情况下获得访问权限。令牌是应用程序令牌。他们是不同的。

此外,根据 error, you do not have enough privilege and you need to configure the permissions. It means that if you still want to use OAuth 2.0 Client Credentials Grant Flow to require access token, you need to provide enough privilege for the service principal(the AD application ) you use. Or you change your code to use OAuth 2.0 code grant flow to require access token. For more details about how to change, please refer to the sample
