問題描述

我正在查看 Microsoft 文檔 這里 和 這里，我在 Azure Active Directory 中創建了 Web 應用程序來訪問 Data Lake Store

I 'm looking at Microsoft Documentation here and here, I have created Web App in Azure Active Directory to access the Data Lake Store

在 Web 應用中，我有 Object ID、Application ID 和 Key

From the Web App I have Object ID, Application ID and Key

查看我看到的文檔:

adlCreds = lib.auth(tenant_id = 'FILL-IN-HERE', client_secret = 'FILL-IN-HERE', client_id = 'FILL-IN-HERE', resource = 'https://datalake.azure.net/')

如何使用它來驗證我的代碼并在 Data Lake Store 上運行操作?

how to use it to authenticate my code and run operation on Data Lake Store?

這是我的完整測試代碼:

here is my full test code:

## Use this for Azure AD authentication
from msrestazure.azure_active_directory import AADTokenCredentials

## Required for Azure Data Lake Store account management
from azure.mgmt.datalake.store import DataLakeStoreAccountManagementClient
from azure.mgmt.datalake.store.models import DataLakeStoreAccount

## Required for Azure Data Lake Store filesystem management
from azure.datalake.store import core, lib, multithread

# Common Azure imports
import adal
from azure.mgmt.resource.resources import ResourceManagementClient
from azure.mgmt.resource.resources.models import ResourceGroup

## Use these as needed for your application
import logging, getpass, pprint, uuid, time


## Declare variables
subscriptionId = 'FILL-IN-HERE'
adlsAccountName = 'FILL-IN-HERE'

tenant_id = 'FILL-IN-HERE'
client_secret = 'FILL-IN-HERE'
client_id = 'FILL-IN-HERE'


## adlCreds = lib.auth(tenant_id = 'FILL-IN-HERE', client_secret = 'FILL-IN-HERE', client_id = 'FILL-IN-HERE', resource = 'https://datalake.azure.net/')
from azure.common.credentials import ServicePrincipalCredentials
adlCreds = lib.auth(tenant_id, client_secret, client_id, resource = 'https://datalake.azure.net/')


## Create a filesystem client object
adlsFileSystemClient = core.AzureDLFileSystem(adlCreds, store_name=adlsAccountName)

## Create a directory
adlsFileSystemClient.mkdir('/mysampledirectory')

當我嘗試運行代碼時，我得到了錯誤:

when I try to ru the code I get error:

有兩種不同的身份驗證方式.第一個是交互式的，適合最終用戶.它甚至適用于多因素身份驗證.這是你如何做到的.您需要進行交互才能登錄.

There are two different ways of authenticating. The first one is interactive which is suitable for end users. It even works with multi factor authentication. Here is how you do it. You need to be interactive in order to log on.

from azure.datalake.store import core, lib, multithread
token = lib.auth()

第二種方法是使用 Azure Active Directory 中的服務主體標識.此處提供了有關設置 Azure AD 應用程序、檢索客戶端 ID 和機密以及使用 SPI 配置訪問權限的分步教程:https://docs.microsoft.com/en-us/azure/data-lake-store/data-lake-store-service-to-service-authenticate-using-active-directory#create-an-active-directory-applicationp>

The second method is to use service principal identities in Azure Active directory. A step by step tutorial for setting up an Azure AD application, retrieving the client id and secret and configuring access using the SPI is available here: https://docs.microsoft.com/en-us/azure/data-lake-store/data-lake-store-service-to-service-authenticate-using-active-directory#create-an-active-directory-application

from azure.common.credentials import ServicePrincipalCredentials
token = lib.auth(tenant_id = '<your azure tenant id>', client_secret = '<your client secret>', client_id = '<your client id>')

這是一篇博文，展示了如何通過 pandas 和 Jupyter 訪問它.它還逐步介紹了如何獲取身份驗證令牌.https://medium.com/azure-data-lake/using-jupyter-notebooks-and-pandas-with-azure-data-lake-store-48737fbad305

Here is blog post that shows how to access it through pandas and Jupyter. It also has a step by step on how to get the authentication token. https://medium.com/azure-data-lake/using-jupyter-notebooks-and-pandas-with-azure-data-lake-store-48737fbad305
