CSN

Updated at：2025-11-11

Retrieve Endpoint

Before configuring the endpoint for SDK usage, please refer to the developer guide section on CSN Service Domain Name to understand endpoint-related concepts.

Note: CSN API supports both HTTP and HTTPS calling methods. To enhance data security, it is recommended to call via HTTPS.

Retrieve AK/SK

To use Baidu AI Cloud CSN, you must have a valid AK (Access Key ID) and SK (Secret Access Key) for signature authentication. These AK/SK credentials are system-generated strings used to identify users and authenticate service access. You can obtain and review your AK/SK information using the following steps:

Create CsnClient

CsnClient serves as the client for CSN services, providing developers with a range of methods to interact with CSN services. When creating a CsnClient, first configure a BCE client configuration-type config instance using endpoint, AK and SK, and then use the config instance to configure the CsnClient. The specific configuration method is as follows:

                Java
                
            

                static final String ENDPOINT = "";
static final String AK = "";
static final String SK = "";
BceClientConfiguration config = new BceClientConfiguration();
config.setCredentials(new DefaultBceCredentials(AK, SK));
config.setEndpoint(ENDPOINT);
CsnClien csnClient = new CsnClien(config);
