This topic describes how to install STS SDK for Python and provides an example about how to use STS SDK for Python.

Background information

  • To use STS SDK for Python, you must install the core library of Alibaba Cloud SDK for Python (aliyun-python-sdk-core) and the STS SDK (aliyun-python-sdk-sts).
  • Alibaba Cloud provides OpenAPI Explorer to simplify API usage. You can use OpenAPI Explorer to debug API operations and dynamically generate SDK sample code.
  • For information about STS API operations, see What is STS?
  • For information about endpoints to access STS, see Endpoints.

Install the SDK for Python

For more information about how to install the SDK for Python, see Quick start.

You can download the installation packages of the SDK for Python from the following links:

Example

The following sample code shows how to call the AssumeRole API operation by using the SDK for Python. You can use OpenAPI Explorer to debug other API operations and obtain sample code.

#!/usr/bin/env python
#coding=utf-8

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdksts.request.v20150401.AssumeRoleRequest import AssumeRoleRequest

# Construct an Alibaba Cloud client to initiate requests.
# When you construct the client, specify your AccessKey ID and AccessKey secret.
client = AcsClient('<accessKeyId>', '<accessSecret>', 'cn-hangzhou')

# Construct a request.
request = AssumeRoleRequest()
request.set_accept_format('json')

# Specify request parameters.
request.set_RoleArn("<RoleArn>")
request.set_RoleSessionName("<RoleSessionName>")

# Initiate the request and obtain a response.
response = client.do_action_with_exception(request)
# python2:  print(response)
print(str(response, encoding='utf-8'))
