Querying Snapshot Tasks

Notes

  • You can query snapshot tasks by task ID, task status, time range, or page number, or perform compound query.
  • If there are more than 10 records and the page number and maximum number of records on each page are not specified, 10 records are displayed by default on each page.

By Task ID

1
2
3
4
5
6
 
// You can query up to 10 tasks.
ListThumbnailsTaskRequest req = new ListThumbnailsTaskRequest().withTaskId(Collections.singletonList("2210744"));
// Send the request to MPC.
ListThumbnailsTaskResponse rsp = initMpcClient().listThumbnailsTask(req);
// Return a message.
System.out.println("rsp=" + JsonUtils.toJSON(rsp));

By Page Number

1
2
3
4
5
6
 
// Set the page number and number of records on each page.
ListThumbnailsTaskRequest req = new ListThumbnailsTaskRequest().withPage(1).withSize(4);
// Send the request to MPC.
ListThumbnailsTaskResponse rsp = initMpcClient().listThumbnailsTask(req);
// Return a message.
System.out.println("rsp=" + JsonUtils.toJSON(rsp));

By Time Range

1
2
3
4
5
 
ListThumbnailsTaskRequest req = new ListThumbnailsTaskRequest().withStartTime("20201220131400").withEndTime("20201220131400");
// Send the request to MPC.
ListThumbnailsTaskResponse rsp = initMpcClient().listThumbnailsTask(req);
// Return a message.
System.out.println("rsp=" + JsonUtils.toJSON(rsp));

By Task Status

1
2
3
4
5
6
 
// Create a request for querying a task by task status.
ListThumbnailsTaskRequest req = new ListThumbnailsTaskRequest().withStatus(ListThumbnailsTaskRequest.StatusEnum.FAILED);
// Send the request to MPC.
ListThumbnailsTaskResponse rsp = initMpcClient().listThumbnailsTask(req);
// Return a message.
System.out.println("rsp=" + JsonUtils.toJSON(rsp));

Compound Query

1
2
3
4
5
 
// Configure the following parameters:
ListThumbnailsTaskRequest req = new ListThumbnailsTaskRequest().withPage(1).withSize(4)
        .withStartTime("20201220131400")
        .withEndTime("20201220131400")
        .withStatus(ListThumbnailsTaskRequest.StatusEnum.FAILED);
