Question

我使用下面的代码来获取存储桶中的对象。我期待一个空的响应，但代码在这里抛出异常。

final ListObjectsRequest listObjectRequest = new ListObjectsRequest().withBucketName(s3Bucket)
                .withMaxKeys(1).withPrefix(prefix);
        final ObjectListing objectListing = s3client.listObjects(listObjectRequest);

参数： s3_bucket =＆gt; “my-bucket / incoming /”和prefix =＆gt; “PRE _”

例外：

com.amazonaws.services.s3.model.AmazonS3Exception: The specified key does not exist. (Service: Amazon S3; Status Code: 404; Error Code: NoSuchKey; Request ID: BF85E6E0CF00717E)

获取AmazonS3Exception：将存储桶名称作为bucket-name / 10020 /传递时，指定的密钥不存在
