【问题描述】：

在尝试使用 Lambda Java 函数检索旧版本 S3 对象的元数据时，我遇到了一个不允许的 405 方法。

AmazonS3 amazonS3 = getAmazonS3();
GetObjectRequest getObjectRequest = new GetObjectRequest(bucket, templateKey, versionId);
ObjectMetadata objectMetadata = amazonS3.getObject(getObjectRequest).getObjectMetadata(); // Exception thrown at this line

public AmazonS3 getAmazonS3() {
    String region = PropertyManager.getValue(PropertyKey.AWS_REGION.getKey(stage));
    return AmazonS3ClientBuilder.standard().withRegion(region)
                .withCredentials(new EnvironmentVariableCredentialsProvider()).build();
    }

Lambda 中的堆栈跟踪：

    The specified method is not allowed against this resource. (Service: Amazon S3; Status Code: 405; Error Code: MethodNotAllowed; Request ID: 1D12DDA5F0493282): com.amazonaws.services.s3.model.AmazonS3Exception

【问题讨论】：

在尝试获取对象本身而不是其元数据时，您是否会遇到同样的异常？
我可以在不指定 versionId 时获取对象。如果我指定，则会收到类似的错误。

【解决方案1】：

一些旧版本的 S3 对象具有删除标记strong>。 AWS 支持表示，尝试将对象作为删除标记的版本导致 405 错误。
