The Alibaba Cloud Python Software Development Kit (SDK) allows you to access Alibaba Cloud services such as Elastic Compute Service (ECS), Object Storage Service (OSS), and Resource Access Management (RAM). You can access Alibaba Cloud services without the need to handle API related tasks, such as signing and constructing your requests.
This document introduces how to obtain and call Alibaba Cloud Python SDK.
-
To use Alibaba Cloud Python SDK, you must have an Alibaba Cloud account as well as an AccessKey.
The AccessKey is required when initializing
AcsClient. You can create an AccessKey in the Alibaba Cloud console. For more information, see Create an AccessKey.Note: To increase the security of your account, we recommend that you use the AccessKey of the RAM user to access Alibaba Cloud services.
-
To use Alibaba Cloud Python SDK to access the APIs of a product, you must first activate the product on the Alibaba Cloud console if required.
-
Alibaba Cloud Python SDK requires 2.6.x, 2.7.x, and Python 3.x.
Alibaba Cloud Python SDK supports Python 2.6.x, 2.7.x, and Python 3.x. Run python --version to check your version of Python.
You can install the Alibaba Cloud Python SDK using the following two methods. Regardless of which method and cloud service are used, the core library aliyun-python-sdk-core must be installed.
-
Install with pip
Python SDK uses a common package management tool named
pip. If pip is not installed, see the pip user guide to install pip.Run the following command to install the individual libraries of Alibaba Cloud services:
# Install the core library pip install aliyun-python-sdk-core # Install the ECS management library pip install aliyun-python-sdk-ecs # Install the RDS management library pip install aliyun-python-sdk-rds
Note: If you are using Python 3.x, run the following command to install the core library:
>`pip install aliyun-python-sdk-core-v3`
-
Install from GitHub
You can clone the source code to your local folder and then run
setup.py installto install the SDK:git clone https://github.com/aliyun/aliyun-openapi-python-sdk.git # Install the core library cd aliyun-python-sdk-core python setup.py install # Install the ECS management library cd aliyun-python-sdk-ecs python setup.py install
-
Import the required modules as follows:
from aliyunsdkcore.client import AcsClient from aliyunsdkcore.acs_exception.exceptions import ClientException from aliyunsdkcore.acs_exception.exceptions import ServerException from aliyunsdkecs.request.v20140526 import DescribeInstancesRequest from aliyunsdkecs.request.v20140526 import StopInstanceRequest
-
Initialize the
AcsClientinstance:client = AcsClient( "<access-key-id>", "<access-key-secret>", "<region-id>" );
where:
-
access-key-idis the Accesskey ID for your account. -
access-key-secretis the AccessKey secret for your account. -
region-idis the ID of the region where the service is called. For a list of region IDs, see Regions and zones.
Note: The sequence of these parameters cannot be changed.
-
-
Initialize a request and print response.
# Initialize a request and set parameters request = DescribeInstancesRequest.DescribeInstancesRequest() request.set_PageSize(10) # Print response response = client.do_action_with_exception(request) print response
##Code example
The following example shows how to query a list of ECS instances in a specific region using DescribeInstances. Substitute the values for
your-access-key-id,your-access-key-secret, andyour-region-id.# -*- coding: utf8 -*- from aliyunsdkcore.client import AcsClient from aliyunsdkcore.acs_exception.exceptions import ClientException from aliyunsdkcore.acs_exception.exceptions import ServerException from aliyunsdkecs.request.v20140526 import DescribeInstancesRequest from aliyunsdkecs.request.v20140526 import StopInstanceRequest # Initialize AcsClient instance client = AcsClient( "<your-access-key-id>", "<your-access-key-secret>", "<your-region-id>" ); # Initialize a request and set parameters request = DescribeInstancesRequest.DescribeInstancesRequest() request.set_PageSize(10) # Print response response = client.do_action_with_exception(request) print response
