演示如何检索操作状态。
代码示例
Java
import com.google.cloud.automl.v1beta1.AutoMlClient;
import com.google.longrunning.Operation;
import java.io.IOException;
class GetOperationStatus {
static void getOperationStatus() throws IOException {
// TODO(developer): Replace these variables before running the sample.
String operationFullId = "projects/[projectId]/locations/us-central1/operations/[operationId]";
getOperationStatus(operationFullId);
}
// Get the status of an operation
static void getOperationStatus(String operationFullId) throws IOException {
// Initialize client that will be used to send requests. This client only needs to be created
// once, and can be reused for multiple requests. After completing all of your requests, call
// the "close" method on the client to safely clean up any remaining background resources.
try (AutoMlClient client = AutoMlClient.create()) {
// Get the latest state of a long-running operation.
Operation operation = client.getOperationsClient().getOperation(operationFullId);
// Display operation details.
System.out.println("Operation details:");
System.out.format("\tName: %s%n", operation.getName());
System.out.format("\tMetadata Type Url: %s%n", operation.getMetadata().getTypeUrl());
System.out.format("\tDone: %s%n", operation.getDone());
if (operation.hasResponse()) {
System.out.format("\tResponse Type Url: %s%n", operation.getResponse().getTypeUrl());
}
if (operation.hasError()) {
System.out.println("\tResponse:");
System.out.format("\t\tError code: %s%n", operation.getError().getCode());
System.out.format("\t\tError message: %s%n", operation.getError().getMessage());
}
}
}
}Python
