如何在 python 脚本上使用命令 azure cli 导出数据库

Question

我使用Azure CLI将资源组中的数据库备份导出到blobstorage ，所以我想在python 脚本上使用相同的命令。

例如，我在 Azure CLI 中使用以下命令导出资源组中的数据库：

az sql db export -s (sql server) -n (database) -g (group) -p (password)
  -u login --storage-key " key "
  --storage-key-type
  --storage-uri (url blob)

如何改用 Python 脚本来实现这一点？

Answer 1

You can use REST API from Python to export an Azure SQL Database as a bacpac.

这是一个示例请求。

POST https://management.azure.com/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/sqlcrudtest-4799/providers/Microsoft.Sql/servers/sqlcrudtest-5961/databases/testdb/export?api-version=2014-04-01

请求正文。

{
  "storageKeyType": "SharedAccessKey",
  "storageKey": "?sr=b&sp=rw&se=2018-01-01T00%3A00%3A00Z&sig=sdfsdfklsdjflSLIFJLSIEJFLKSDJFDd/%2wdfskdjf3%3D&sv=2015-07-08",
  "storageUri": "https://test.blob.core.windows.net/bacpacs/testbacpac.bacpac",
  "administratorLogin": "dummyLogin",
  "administratorLoginPassword": "Un53cuRE!",
  "authenticationType": "SQL"
}

示例响应。

  "id": "/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/sqlcrudtest-4799/providers/Microsoft.Sql/servers/sqlcrudtest-5961/importExportOperationResult/f01d7bfe-7162-44e7-9350-f1c85ce83e4c",

    "serverName": "test",
    "databaseName": "testdb",
    "status": "Completed",
    "errorMessage": null
  }
}

确保使用 pip 安装azure-mgmt-sql==0.16.0 package。

调整以下代码段中的参数，您应该对 go 很好。

from azure.common.credentials import ServicePrincipalCredentials
from azure.mgmt.sql import SqlManagementClient
from azure.mgmt.sql.models import StorageKeyType, AuthenticationType
from msrestazure.azure_exceptions import CloudError


TENANT_ID = '<your_tennant_id>'
CLIENT = '<your_client_id>'
KEY = '<your_client_key>'
SUBSCRIPTION_ID = '<your_subscription_id>'

credentials = ServicePrincipalCredentials(
    client_id=CLIENT,
    secret=KEY,
    tenant=TENANT_ID
)

sql_client = SqlManagementClient(credentials, SUBSCRIPTION_ID)

kwargs = dict()
kwargs['storage_key_type'] = 'StorageAccessKey'
kwargs['storage_key'] = '<your_storage_account_key'
kwargs['storage_uri'] = 'https://<name>.blob.core.windows.net/<container>/<name>.bacpac'
kwargs['administrator_login'] = '<admin_name>'
kwargs['administrator_login_password'] = '<admin_password>'
kwargs['authentication_type'] = 'SQL'

try:
    poller = sql_client.databases.export(
        database_name='<your_db_name>',
        server_name='<your_server_name>',
        resource_group_name='<your_rg_name>',
        storage_key_type='StorageAccessKey',
        storage_key='<your_storage_account_key',
        parameters=kwargs)

    print(poller.result())

except CloudError as err:
    print(err.error)
    print(err.message)
