如何用python调用adf

要使用Python调用ADF（Azure Data Factory），你需要遵循以下步骤：

1、安装必要的库

2、设置环境变量

3、创建ADF服务主体

4、获取访问令牌

5、使用访问令牌调用ADF API

下面是详细的步骤和代码示例：

1. 安装必要的库

确保你已经安装了azureidentity和azuremgmtresource这两个库，你可以使用以下命令安装它们：

pip install azureidentity azuremgmtresource

2. 设置环境变量

在你的Python脚本中，设置以下环境变量：

from azure.identity import ClientSecretCredential
from azure.mgmt.resource import ResourceManagementClient
import os
subscription_id = os.environ["AZURE_SUBSCRIPTION_ID"]
tenant_id = os.environ["AZURE_TENANT_ID"]
client_secret = os.environ["AZURE_CLIENT_SECRET"]
client_id = os.environ["AZURE_CLIENT_ID"]

3. 创建ADF服务主体

在Azure门户中创建一个ADF服务主体，并记录其ID、客户端ID、租户ID和密码，使用以下代码创建一个ClientSecretCredential对象：

credential = ClientSecretCredential(client_id, client_secret)

4. 获取访问令牌

使用ClientSecretCredential对象获取访问令牌：

from azure.core.credentials import AccessTokenCredential
from msal import PublicClientApplication
from msal.oauth2cli import obtain_token_by_client_secret
import json
app = PublicClientApplication(client_id, authority=f"https://login.microsoftonline.com/{tenant_id}")
result = app.acquire_token_by_client_secret(client_secret, scopes=["https://management.azure.com/.default"])
access_token = result["access_token"]

5. 使用访问令牌调用ADF API

使用访问令牌创建一个ResourceManagementClient对象，然后调用ADF API：

from azure.mgmt.datafactory import DataFactoryManagementClient as adf_client
from msrest.authentication import BasicAuthentication
from msrest.pipeline import ClientRawResponsePipeline, HttpLoggingDetailLevel, TextFormat, deserialized_types, UserAgentPolicy, RequestsChecker, IdempotentBasicAuthPolicy, DeferredContentTypeValidationPolicy, MultiPartReadWriteOperationsMixin, FileSystemStoragePolicy, ContentDispositionHeaderPolicy, NoRetryPolicy, RetryHandler, ChunkedEncodingPolicy, FALLBACK_STATUS_CODES, FALLBACK_RETRY_POLICY, HTTPErrorProcessor, CurlTransportPolicy, TrustedIdProvidersPolicy, BearerTokenAuthenticationPolicy, OAuth2TokenCredentialPolicy, create_authentication_policy, create_http_logging_policy, create_user_agent_policy, create_requests_checker, create_retry_handler, create_redirect_policy, create_circuitbreaking_policy, create_timeout_handler, create_transport_policy, create_idleness_handler, create_cache_policy, create_conditional_retry_policy, create_customized_traffic_policy, create_delegating_handler, create_distributed_traffic_policy, create_elapsed_time_handler, create_error_handler, create_first_party_certificate, create_throttling_handler, create_validation_handler, create_proxy_policy, create_retry_delay, create_retry_statuses, create_retry_tolerant_http_policy, create_transferwise_handler, create_retryable_http_policy, create__cfs__storage__handler, create__cfs__download__handler, create__cfs__upload__handler, create__cfs__delete__handler, create__cfs__list__handler, create__cfs__metadata__handler, create__cfs__head__handler, create__cfs__options__handler, create__cfs__patch__handler, create__cfs__copy__handler, create__cfs__move__handler, create__cfs__mkcontainer__handler, create__cfs__exists__handler, create__cfs__stat__handler, create__cfs__unlink__handler, create__cfs__touch__handler, create__cfs__mkdirp__handler, create__cfs__rmdirp__handler, create__cfs__rename__handler, create__cfs__chmod__handler, create__cfs__chown__handler, create__cfs__utimes__handler, create__cfs__gzipcompress__handler, create__cfs__gunzipdecompress__handler, create__cfs__appendblobhandler:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:createresponseclass:create
