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

Background information

  • To use an 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 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 code provides an example on how to call the AssumeRole API operation by using the SDK for Python. For information about other API operations, visit OpenAPI Explorer, debug 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 that is used to initiate requests.
# When you construct the client, specify the AccessKey ID and AccessKey secret.
client = AcsClient('<accessKeyId>', '<accessSecret>', 'cn-hangzhou')

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

# Configure 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'))
