    Server Migration Center:Use SMC SDK for Python

    Last Updated:Aug 20, 2024

    This topic describes how to install the environment for using Server Migration Center (SMC) SDK for Python and run the sample code to call an API operation.

    Prerequisites

    • Python 3 is downloaded and installed.

      Run the python --version command on the terminal to check the Python version.

    • A Python code editor is downloaded.

      In this example, PyCharm is used.

    • An AccessKey pair is obtained.

      When you call an API operation, you must use an AccessKey pair to complete identity authentication. An AccessKey pair consists of an AccessKey ID and an AccessKey secret. For more information about how to create an AccessKey pair, see Create an AccessKey pair.

    Procedure

    Step 1: Configure environment variables

    In this example, environment variables are configured to manage the AccessKey pair. This prevents security risks that are caused by hard-coding the AccessKey pair into your business code. For more information, see Configure environment variables in Linux, macOS, and Windows.

    Step 2: Install dependencies

    Use one of the following methods to install the dependencies:

    Note

    If pip is not installed, visit the official website of pip to download and install pip. For more information, see Installation. 

    pip install alibabacloud_credentials
pip install alibabacloud_smc20190601==1.0.2
pip install alibabacloud_tea_console==0.0.1
pip install alibabacloud_tea_util==0.3.11
pip install alibabacloud_tea_openapi==0.3.8

    Step 3: Download the sample SDK project

    1. Go to the

      API debugging page of OpenAPI Portal. In the left-side navigation pane, select an API operation that you want to call.

      In this example, the DescribeSourceServers operation is selected.

    2. In the DescribeSourceServers pane, specify the Region parameter and click the Parameters tab. On the Parameters tab, specify the request parameters. When you specify the request parameters of the API operation, you can refer to the information on the Document tab on the right. On this tab, you can also learn about the limits and usage notes of an API operation, especially the billing information, and the specific meaning and usage of each parameter in the request.

    3. On the SDK Sample Code tab, select Python for the Languages parameter and click Download Project.
