如何在 Amazon S3 中创建文件夹

本文关键字：创建 文件夹 S3 Amazon | 更新日期: 2024-10-30 20:57:59

下面是我将文档上传到 S3 的代码，它工作正常，但你能帮忙吗，如果存储桶不存在，我如何在存储桶中创建一个文件夹并将文件上传到该文件夹

try
        {
            TransferUtility fileTransferUtility = new
            TransferUtility(new AmazonS3Client(Amazon.RegionEndpoint.USEast1));
            // Specify advanced settings/options.
            TransferUtilityUploadRequest fileTransferUtilityRequest = new TransferUtilityUploadRequest
            {
                BucketName = existingBucketName,
                FilePath = filePath,
                StorageClass = S3StorageClass.ReducedRedundancy,
                PartSize = 9291456, // 6 MB.
                Key = keyName,
                CannedACL = S3CannedACL.PublicRead
            };
            fileTransferUtility.UploadDirectory("C:''Build", existingBucketName);
            fileTransferUtilityRequest.Metadata.Add("param1", "Value1");
            fileTransferUtilityRequest.Metadata.Add("param2", "Value2");
            fileTransferUtility.Upload(fileTransferUtilityRequest);
            Console.WriteLine("Upload 4 completed");
        }
        catch (AmazonS3Exception s3Exception)
        {
            Console.WriteLine(s3Exception.Message,
                              s3Exception.InnerException);
        }

如何在 Amazon S3 中创建文件夹

public void CreateFolder(string awsBucketName, string awsFolderName)
{
    EncryptionMaterials encryptionMaterials = new EncryptionMaterials(RSA.Create());
    AmazonS3EncryptionClient client = new AmazonS3EncryptionClient(encryptionMaterials);
        if ((cloudKaseClient != null) & (_Security.IsTokenAuthenticate(tokenUsr, tokenPasswd)))
        {
            PutObjectRequest putObjectRequest = new PutObjectRequest
            {
                BucketName = awsBucketName,
                StorageClass = S3StorageClass.Standard,
                ServerSideEncryptionMethod = ServerSideEncryptionMethod.AES256,
                CannedACL = S3CannedACL.Private,
                Key = awsFolderName + "/",
                ContentBody = awsFolderName
            };
            client.PutObject(putObjectRequest);
    }
}

对于 Amazon S3 的概念，如果您想区分文件和文件夹而不是文件夹路径，请按带"/"的路径获取，对于文件路径，则不带"/"。

此外，如果您想创建带有"/"的文件夹名称，则 Amazon s3 浏览器会创建不带"/"的文件夹。

用于创建文件，请使用以下代码

public void CreateFile(string awsBucketName, string awsFolderName)
{
    EncryptionMaterials encryptionMaterials = new EncryptionMaterials(RSA.Create());
    AmazonS3EncryptionClient client = new AmazonS3EncryptionClient(encryptionMaterials);
        if ((cloudKaseClient != null) & (_Security.IsTokenAuthenticate(tokenUsr, tokenPasswd)))
        {
            PutObjectRequest putObjectRequest = new PutObjectRequest
            {
                BucketName = awsBucketName,
                StorageClass = S3StorageClass.Standard,
                ServerSideEncryptionMethod = ServerSideEncryptionMethod.AES256,
                CannedACL = S3CannedACL.Private,
                Key = awsFolderName,
                ContentBody = awsFolderName
            };
            client.PutObject(putObjectRequest);
    }
}

重要的是要知道 Amazon S3 中没有文件夹的概念。这些只是带有斜杠的长 S3 文件名，用于对 Amazon S3 对象进行分组。

通过发送 PUT 对象请求，您可以创建一个文件夹。在请求中，您需要在其名称中输入"/"，然后用"/"分隔字符串，文件大小为零。
