Client & Credentials

Using AccessKey call

from aliyunsdkcore.client import AcsClient
from aliyunsdkecs.request.v20140526.AcceptInquiredSystemEventRequest import AcceptInquiredSystemEventRequest

# Create and initialize a AcsClient instance
client = AcsClient(
  '<access_key_id>', # The AccessKey ID of the RAM account
  '<access_secret>', # The AccessKey Secret of the RAM account
  '<region_id>' # The region ID
)

# Create an API request and set parameters
request = AcceptInquiredSystemEventRequest()
request.set_accept_format('json')
# Initiate the request and handle the response or exceptions
response = client.do_action_with_exception(request)

print(str(response, encoding='utf-8'))

Use the default credential provider chain

  1. Environment Credentials

Look for environment credentials in environment variable. If the ALIYUN_ACCESS_KEY_ID and ALIYUN_ACCESS_KEY_SECRET environment variables are defined and are not empty, the program will use them to create default credentials.

from aliyunsdkcore.client import AcsClient
from aliyunsdkecs.request.v20140526.AcceptInquiredSystemEventRequest import AcceptInquiredSystemEventRequest

client = AcsClient(
  region_id='<region_id>'
)

request = AcceptInquiredSystemEventRequest()
request.set_accept_format('json')
response = client.do_action_with_exception(request)

print(str(response, encoding='utf-8'))
  1. STS Credentials

Create a temporary security client by applying Temporary Security Credentials (TSC) through the Security Token Service (STS).

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.auth.credentials import StsTokenCredential
from aliyunsdkecs.request.v20140526.AcceptInquiredSystemEventRequest import AcceptInquiredSystemEventRequest

cred = StsTokenCredential(
    sts_access_key_id = '<sts_access_key_id>',
    sts_access_key_secret = '<sts_access_key_secret>',
    sts_token = '<sts_token>'
)

client = AcsClient(
    region_id='<region_id>',
    credential=cred
)

request = AcceptInquiredSystemEventRequest()
request.set_accept_format('json')
response = client.do_action_with_exception(request)

print(str(response, encoding='utf-8'))
  1. RamRoleArn Credentials

By specifying RAM Role, the client will be able to automatically request maintenance of STS Token before making a request, and be automatically converted to a time-limited STS client. You may also apply for Token maintenance by yourself before creating STS Client.

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.auth.credentials import RamRoleArnCredential
from aliyunsdkecs.request.v20140526.AcceptInquiredSystemEventRequest import AcceptInquiredSystemEventRequest

cred = RamRoleArnCredential(
    sts_access_key_id='<sts_access_key_id>',
    sts_access_key_secret='<sts_access_key_secret>',
    role_arn='<role_arn>',
    session_role_name='<session_role_name>'
)

client = AcsClient(
    region_id='<region_id>',
    credential=cred
)

request = AcceptInquiredSystemEventRequest()
request.set_accept_format('json')
response = client.do_action_with_exception(request)

print(str(response, encoding='utf-8'))
  1. EcsRamRole Credentials

When instantiating Esc Ram role credentials, the program will carry the specified role name and request http://100.100.100.200/latest/meta-data/ram/security-credentials/ to obtain temporary security credentials.

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.auth.credentials import EcsRamRoleCredential
from aliyunsdkecs.request.v20140526.AcceptInquiredSystemEventRequest import AcceptInquiredSystemEventRequest

cred = EcsRamRoleCredential(
    role_name='<role name>'
)

client = AcsClient(
    region_id='<region_id>',
    credential=cred
)

request = AcceptInquiredSystemEventRequest()
request.set_accept_format('json')
response = client.do_action_with_exception(request)

print(str(response, encoding='utf-8'))
