Confirm Endpoint

Baidu AI Cloud currently supports multiple regions. Please refer to[Region Selection Guide](Reference/Region Selection Instructions/Region.md).

Currently, only the "North China-Beijing" region is supported. Beijing region: https://iam.bj.baidubce.com Corresponding information:

Access region	Endpoint	Supported protocols
BJ	iam.bj.baidubce.com	HTTP,HTTPS

Retrieve access key

To use Baidu AI Cloud IAM, you need valid AK (Access Key ID) and SK (Secret Access Key) credentials for signature authentication. AK/SK are system-assigned strings used for user identification and signature verification in IAM. You can obtain and understand your AK/SK details using the following steps:

Create AK/SK

Create IamClient

The IamClient acts as the client for IAM services, offering developers a range of methods to interact with IAM services.

Before creating IamClient, a configuration file must be created to configure IamClient. Below, this configuration file is named iam_sample_conf.py, with the following specific configuration information:

                Python
                
            

                #Import standard logging module
import logging
 #Introduce configuration management module and security certification module
from baidubce.bce_client_configuration import BceClientConfiguration
from baidubce.auth.bce_credentials import BceCredentials
 #Set the Host, Access Key ID and Secret Access Key
HOST = ''
AK = ''
SK = ''
 #Set log file handles and log levels
logger = logging.getLogger('baidubce.services.iam.iamclient')
fh = logging.FileHandler('sample.log')
fh.setLevel(logging.DEBUG)
 #Set the order, structure and content of log file output
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
fh.setFormatter(formatter)
logger.setLevel(logging.DEBUG)
logger.addHandler(fh)
 #Create BceClientConfiguration instance
config = BceClientConfiguration(credentials=BceCredentials(AK, SK), endpoint=HOST)
            

Create IamClient, refer to sample/iam/iam_sample.py

                Python
                
            

                #Import configuration module
import iam_sample_conf
 #Import IamClient module
from baidubce.services.iam.iam_client import IamClient
 #Create IamClient
iam_client = IamClient(iam_sample_conf.config)
            

Configure IamClient

Set network parameters

Users can set some network parameters:

                Python
                
                    #Set request timeout duration
iam_sample_conf.config.connection_timeout_in_mills = TIMEOUT
    	
 #Set receive buffer size
iam_sample_conf.config.recv_buf_size(BUF_SIZE)

 #Set send buffer size
iam_sample_conf.config.send_buf_size(BUF_SIZE)

 #Set connection retry policy
 #Three-time exponential backoff retry
iam_sample_conf.config.retry_policy = BackOffRetryPolicy()

Parameter description

The following parameters can be configured via BceClientConfiguration:

Parameters	Description
send_buf_size	Send buffer size
recv_buf_size	Receive buffer size
connection_timeout_in_mills	Request timeout duration (unit: millisecond)
retry_policy	For the connection retry policy, default to three-time exponential backoff during Client initialization
