Querying Task Execution Status

Function

This API is used to query the execution status of an asynchronous request task.

After an asynchronous request task is issued, for example, creating or deleting an ECS, performing operations on ECSs in a batch, or performing operations on ECS NICs, a task ID will be returned, based on which you can query the execution status of the task.

For details about how to obtain the task ID, see Responses (Task).

URI

GET /v1/{project_id}/jobs/{job_id}

Table 1 describes the parameters in the URI.

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the ID, see Obtaining a Project ID.
job_id	Yes	Specifies the ID of an asynchronous request task.

Request

None

Response

Table 2 describes the response parameters.

**Table 2** Response parameters
Parameter	Type	Description
status	String	Specifies the task status. SUCCESS: indicates the task is successfully executed. RUNNING: indicates that the task is in progress. FAIL: indicates that the task failed. INIT: indicates that the task is being initialized.
entities	Object	Specifies the object of the task. The value of this parameter varies depending on the type of the task. If the task is an ECS-related operation, the value is server_id. If the task is a NIC operation, the value is nic_id. If a sub-Job is available, details about the sub-job are displayed. For details, see Table 3.
job_id	String	Specifies the ID of an asynchronous request task.
job_type	String	Specifies the type of an asynchronous request task.
begin_time	String	Specifies the time when the task started.
end_time	String	Specifies the time when the task finished.
error_code	String	Specifies the returned error code when the task execution fails. After the task is executed successfully, the value of this parameter is null.
fail_reason	String	Specifies the cause of the task execution failure. After the task is executed successfully, the value of this parameter is null.
message	String	Specifies the error message returned when an error occurs in the request to query a task.
code	String	Specifies the error code returned when an error occurs in the request to query a task. For details about the error code, see Returned Values for General Requests.

**Table 3** **entities** field description
Parameter	Type	Description
server_id	String	If the task is an ECS-related operation, the value is server_id.
nic_id	String	If the task is a NIC-related operation, the value is nic_id.
sub_jobs_total	Integer	Specifies the number of subtasks.
sub_jobs	Array of objects	Specifies the execution information of a subtask. For details, see Table 4.

**Table 4** **sub_jobs** field description
Parameter	Type	Description
status	String	Specifies the task status. SUCCESS: indicates the task is successfully executed. RUNNING: indicates that the task is in progress. FAIL: indicates that the task failed. INIT: indicates that the task is being initialized.
entities	Object	Specifies the object of the task. The value of this parameter varies depending on the type of the task. If the task is an ECS-related operation, the value is server_id. If the task is a NIC operation, the value is nic_id. For details, see Table 5.
job_id	String	Specifies the subtask ID.
job_type	String	Specify the subtask type.
begin_time	String	Specifies the time when the task started.
end_time	String	Specifies the time when the task finished.
error_code	String	Specifies the returned error code when the task execution fails. After the task is executed successfully, the value of this parameter is null.
fail_reason	String	Specifies the cause of the task execution failure. After the task is executed successfully, the value of this parameter is null.

**Table 5** **sub_jobs.entities** field description
Parameter	Type	Description
server_id	String	If the task is an ECS-related operation, the value is server_id.
nic_id	String	If the task is a NIC-related operation, the value is nic_id.
errorcode_message	String	Indicates the cause of a subtask execution failure.
