Obtaining Service Objects

You can use the API to obtain the service object list of a user.

Sample Code

In ModelArts notebook, you do not need to enter authentication parameters for session authentication. For details about session authentication of other development environments, see Session Authentication.

Scenario 1: Obtain all service objects of a user.

      
           from modelarts.session import Session
from modelarts.model import Predictor

session = Session()
predictor_list_object_resp = Predictor.get_service_object_list(session)
print(predictor_list_object_resp)

Scenario 2: Obtain the service objects of a user based on search criteria.

      
           from modelarts.session import Session
from modelarts.model import Predictor

session = Session()
predictor_object_list = Predictor.get_service_object_list(session, service_name="digit", order="asc", offset="0", infer_type="real-time")
print(predictor_object_list)

Parameters

You can use the API to obtain the service list. The list size is equal to the number of services deployed by the user. Each element in the list is a predictor object. The object attributes are the same as those in service initialization.
For example, in service_list_resp = [service_instance1, service_instance2, service_instance3 ...], each service_instance in the list is a service API that can be called in the service management section.
The service list can be queried based on the query parameters. Table 1 describes the query parameters.
When the model list is queried, details about the services are returned. See Table 2 and Table 3.

**Table 1** Query parameters
Parameter	Mandatory	Type	Description
session	Yes	Object	Session object. For details about the initialization method, see Session Authentication.
is_show	No	Boolean	Whether to print service object information. Default value: True
service_id	No	String	Service ID. By default, the service ID is not filtered.
service_name	No	String	Service name. By default, the service name is not filtered.
infer_type	No	String	Inference mode. The value can be real-time or batch. By default, this parameter is left blank.
offset	No	Integer	Start page of the paging list. Default value: 0
