c# - 如何在 Amazon S3 中创建文件夹

Question

下面是我将文档上传到 S3 的代码，它工作正常但是你能帮助我如何在不存在的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);
        }

Answer 1

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，如果您想要区分文件和文件夹，而不是通过带“/”的路径获取文件夹路径，而对于不带“/”的文件路径获取。

此外，如果您想创建带有“/”的文件夹名称，而不是 amazon s3 浏览器，请创建不带“/”的文件夹。

创建文件使用下面的代码

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);

    }
}
