如何在python脚本上使用azure cli命令导出数据库

我使用Azure CLI将资源组中的数据库导出到blobstorage，因此我希望在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我的资源组中的数据库：

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)

---

如何使用Python脚本实现这一点？

您可以使用Python中的REST API将Azure SQL数据库导出为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

请求主体

{
  "storageKeyType": "SharedAccessKey",
  "storageKey": "?sr=b&sp=rw&se=2018-01-01T00%3A00%3A00Z&sig=sdfsdfklsdjflSLIFJLSIEJFLKSDJFDd/%2wdfskdjf3%3D&sv=2015-07-08",

  "administratorLogin": "dummyLogin",
  "administratorLoginPassword": "Un53cuRE!",
  "authenticationType": "SQL"
}

样本响应

确保使用pip安装azure管理sql==0.16.0包

在下面的代码段中调整参数，您就可以开始了

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)

来自azure.common.credentials导入服务PrincipalCredentials
从azure.mgmt.sql导入SqlManagementClient
从azure.mgmt.sql.models导入StorageKeyType、AuthenticationType
从msrestazure.azure\u异常导入CloudError
