CredentialProviderChain

This API returns temporary credentials for an Alibaba Cloud service. The credentials are automatically updated every 15 minutes by default. Call this API to retrieve the latest credentials before you access the service. The credential format includes the following parameters:

Parameter	Type	Description
accessKeyId	String	The AccessKey ID. An AccessKey pair consists of an AccessKey ID and an AccessKey secret. It is used for identity authentication in API requests to Alibaba Cloud services.
accessKeySecret	String	The AccessKey secret.
securityToken	String	The security token.

The following example shows how to use CredentialProviderChain().get_credential() to access the OSS service.

import oss2
import lecoresdk

def handler(event, context):
  cred = lecoresdk.CredentialProviderChain().get_credential()
  auth = oss2.StsAuth(cred['accessKeyId'], cred['accessKeySecret'], cred['securityToken'])
  bucket = oss2.Bucket(auth, 'http://oss-cn-shanghai.aliyuncs.com', 'le-fc-bucket')
  bucket.put_object('fileFromEdgePy.txt', 'Content of object')
  print("-- Put fileFromEdgePy.txt to OSS.")
  return 'OK'
