未使用 Python 在 MS Fabric API 中为服务主体令牌授予身份验证

Question

我正在尝试在 VScode 中使用 Python 连接到 Microsoft Fabric 中的 OneLake API。

到目前为止我已经

1. 使用这些 API 权限在 Azure 中注册了一个应用程序

2. 然后为我的服务主体创建一个秘密
3. 然后我尝试使用 azure.identity 通过此函数获取令牌：

from azure.identity import ClientSecretCredential, AuthenticationRequiredError

def get_access_token(app_id, client_secret, directory_id):
    try:
        # Create the ClientSecretCredential using the provided credentials
        credential = ClientSecretCredential(
            client_id=app_id,
            client_secret=client_secret,
            tenant_id=directory_id
            #scope="https://storage.azure.com/.default"
        )

        # Use the credential to get the access token
        token = credential.get_token("https://storage.azure.com/.default").token

        return token, credential

    except AuthenticationRequiredError as e:
        print("Authentication failed. Please check your credentials.")
        raise e

    except Exception as e:
        print("An error occurred while getting the access token:")
        print(str(e))
        raise e
    
access_token, credential = get_access_token(app_id, client_secret, directory_id)

看来我得到了令牌。但权限、范围或访问权限有问题。因为当我运行此函数来检查连接时，我收到状态代码 400

def check_connection_with_onelake(access_token):
    base_url = "https://onelake.dfs.fabric.microsoft.com/9c3ffd43-b537-4ca2-b9ba-0c59d0094033/Files/sample?resource=file" 
    token_headers = {
        "Authorization": "Bearer " + access_token
    }

    try:
        response = requests.put(base_url, headers=token_headers)

        if response.status_code == 200:
            print("Connection with OneLake is successful.")
        else:
            print("Failed to connect with OneLake. Status code:", response.status_code)

    except requests.exceptions.RequestException as e:
        print("An error occurred while checking the connection:", str(e))

# Assuming 'access_token' is already defined and contains a valid access token
check_connection_with_onelake(access_token)

4. 我还以管理员身份将应用程序的服务主体添加到 Fabric 工作区中的用户

我在哪里缺少访问权限以及如何授予正确的访问权限？
