通过Amazon.S3 nuget包的Scaleway提供的S3

Question

我想使用Scaleway对象存储(S3标准) (https://www.scaleway.com/en/object-storage/)的Scaleway nuget包。

但我得到了这样的错误：“‘授权标头格式错误；区域'us-east-1’错误；应为'fr-par'”“

我需要更改我的区域，但是如何更改呢？谢谢

    public static async Task UploadFile(FileStream file, string bucket = "default")
    {
         var config = new AmazonS3Config { ServiceURL = endPoint };
        using (var client = new AmazonS3Client(keyId, secretAccessKey, config))
        {

            using (var newMemoryStream = new MemoryStream())
            {
                var uploadRequest = new TransferUtilityUploadRequest
                {
                    InputStream = file, 
                    Key = file.Name,
                    BucketName = bucket,
                    CannedACL = S3CannedACL.PublicRead
                };

                var fileTransferUtility = new TransferUtility(client);
                await fileTransferUtility.UploadAsync(uploadRequest);
            }
        }
    }

存储团队成员@ Scaleway。

感谢您使用我们的服务，

不幸的是，C#中的AWS不允许您自定义请求区域和端点，只有一个是可能的。

目前，我们建议您暂时使用MinIO开发工具包(请参阅此处：https://github.com/minio/minio-dotnet)

尽管如此，

我们知道这种情况，并正在研究解决方案。

示例

首先安装sdk

dotnet add package Minio --version 3.1.4

然后代码

using System;
using System.IO;
using Minio;
using Minio.Exceptions;
using Minio.DataModel;
using System.Threading.Tasks;

namespace FileUploader
{
    class FileUpload
    {
        static void Main(string[] args)
        {
            try
            {
                var minio = new MinioClient(
                    "s3.fr-par.scw.cloud",
                    "SCWXXXXXXXXXXX",
                    "xxxxx-xxxx-xxx-xxxxx-xxxx",
                    "fr-par"
                ).WithSSL();

                string [] fileEntries = Directory.GetFiles("/app");
                foreach(string fileName in fileEntries) {
                    FileUpload.Run(minio, fileName).Wait();
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

        // File uploader task.
        private async static Task Run(MinioClient minio, string file)
        {
            try
            {
                await minio.PutObjectAsync("my-bucket", Path.GetFileName(file), file, "");
                Console.WriteLine("Successfully uploaded " + file );
            }
            catch (MinioException e)
            {
                Console.WriteLine("File Upload Error: {0}", e.Message);
            }
        }
    }
}

如果您的存储桶区域是'fr-par'，则可以使用引用欧盟西部(巴黎)端点的EUWest3端点。

var config = new AmazonS3Config
{
    RegionEndpoint = RegionEndpoint.EUWest3,
    ServiceURL = "https://s3.fr-par.scw.cloud/"
}
