与 AWS SDK或DescribeDocumentClassificationJob一起使用 CLI

以下代码示例演示如何使用 DescribeDocumentClassificationJob。

操作示例是大型程序的代码摘录，必须在上下文中运行。在以下代码示例中，您可以查看此操作的上下文：

AWS CLI

描述文档分类作业

以下 describe-document-classification-job 示例将获取异步文档分类作业的属性。

aws comprehend describe-document-classification-job \
    --job-id 123456abcdeb0e11022f22a11EXAMPLE

输出：

{
    "DocumentClassificationJobProperties": {
        "JobId": "123456abcdeb0e11022f22a11EXAMPLE",
        "JobArn": "arn:aws:comprehend:us-west-2:111122223333:document-classification-job/123456abcdeb0e11022f22a11EXAMPLE",
