Cloudflare R2 在存储桶之间移动对象不适用于 S3 SDK

Question

我尝试在两个资源之间移动我的对象。 首先，我执行 CopyRequest，然后执行 DeleteRequest。但是当我尝试移动对象时，出现以下错误：

Header 'x-amz-tagging-directive' with value 'COPY' not implemented

。

我尝试在创建 CopyObjectRequest 实例后删除标头，但没有名称相似的标头。另外，在创建 CopyObjectRequest 的新实例时，我没有看到任何配置。

S3客户端的配置和实例

var config = new AmazonS3Config
        {
            ServiceURL = SabiartConfig.SabiartS3Domain
        };
        
var credentials = new BasicAWSCredentials(SabiartConfig.SabiartS3Key, SabiartConfig.SabiartS3Secret);

_client = new AmazonS3Client(credentials, config);

await _fileService.MoveToBucket(fileIdString, SabiartConfig.SabiartS3TemporaryBucketName,
            SabiartConfig.SabiartS3PublicBucketName);

移动代码：

public async Task MoveToBucket(string fileIdString, string originBucket, string destinationBucket)
    {
        var request = new CopyObjectRequest
        {
            SourceBucket = originBucket,
            SourceKey = fileIdString,
            DestinationBucket = destinationBucket,
            DestinationKey = fileIdString
        };
        
        await _client.CopyObjectAsync(request);
        await DeleteAsync(fileIdString, originBucket);
    }

Answer 1

根据 CloudFlare 文档，仍然不支持

x-amz-tagging-directive

标头：

❌ x-amz-标记指令

CopyObject

API 本身并不严格需要

x-amz-tagging-directive

标头，因为 S3 内部默认为

COPY

；如果未发送标头，CloudFlare 可能会在幕后执行无操作，但 .NET SDK 不提供省略此标头的方法。它总是为此标头设置一个值，以确定是否需要复制对象的标签。

你可以从源代码中看到这一点：

if (copyObjectRequest.IsSetTagSet())
{
    request.Headers.Add(S3Constants.AmzHeaderTagging, AmazonS3Util.TagSetToQueryString(copyObjectRequest.TagSet));
    request.Headers.Add(S3Constants.AmzHeaderTaggingDirective, TaggingDirective.REPLACE.Value);
}
else
{
    request.Headers.Add(S3Constants.AmzHeaderTaggingDirective, TaggingDirective.COPY.Value);
}

不幸的是，在 CloudFlare 支持此标头之前，您需要手动

GetObject

和

PutObject

跨越对象。
