如何通过 ASP.NET Core 中的端点在 AWS S3 存储桶中上传文件

Question

我正在使用 ASP.NET Core 和 AWSSDK.S3 nuget 包。

我可以通过提供 accessKeyID、secretKey、bucketName 和 region

来上传文件

像这样：

var credentials = new BasicAWSCredentials(accessKeyID, secretKey);

   using (var client = new AmazonS3Client(credentials, RegionEndpoint.USEast1))
   {
       var request = new PutObjectRequest
       {
             AutoCloseStream = true,
             BucketName = bucketName,
             InputStream = storageStream,
             Key = fileName
       }
   }

但我只有一个 URL 来上传文件

11.11.11.111:/aa-bb-cc-dd-useast1

如何通过 URL 上传文件？我是 AWS 新手，如果能得到一些帮助，我将不胜感激。

       private const string filePath = "*** provide the full path name of the file to upload ***";
        // Specify your bucket region (an example region is shown).
        private static readonly RegionEndpoint bucketRegion = RegionEndpoint.USWest2;
        private static IAmazonS3 s3Client;

        public static void Main()
        {
            s3Client = new AmazonS3Client(bucketRegion);
            UploadFileAsync().Wait();
        }

        private static async Task UploadFileAsync()
        {
            try
            {
                var fileTransferUtility =
                    new TransferUtility(s3Client);  
                // Option 1. Upload a file. The file name is used as the object key name.
               await fileTransferUtility.UploadAsync(filePath, bucketName);
               Console.WriteLine("Upload 1 completed");

             }
         }
      }
    }

您可以使用提供的访问点代替存储桶名称。
