使用适用于 .NET 的 AWS SDK 上传到 Google 云存储`预期哈希值不等于计算哈希值`

Question

我正在尝试使用适用于 .NET 的 AWS 开发工具包上传到 Google 云存储。我在 GCS 上启用了互操作性模式，并将 AWSSecretKey 和 AWSAccessKey 放入我的 App.config 中。我可以列出对象，但上传对我不起作用。

我使用的代码是

            AmazonS3Config c = new AmazonS3Config();
            c.ServiceURL = "https://storage.googleapis.com";
            client = new AmazonS3Client(c);
            PutObjectRequest request = new PutObjectRequest()
            {
                ContentBody = "asdf",
                BucketName = bucketName,
                Key = keyName
            };
            client.PutObject(request);

但是我得到的结果是：

相同的代码在 S3 上工作正常（减去设置 ServiceURL）

Answer 1

GCS 文档说：

In the Cloud Storage XML API, chunked transfer encoding and V4 signatures cannot currently be used simultaneously. Some Amazon S3 tools use chunked transfer encoding along with signatures by default; you should disable chunked transfer encoding in such cases.

我发现要解决此错误，我需要将 UseChunkEncoding = false 添加到 PutObjectRequest：

            PutObjectRequest request = new PutObjectRequest()
            {
                ContentBody = "asdf",
                BucketName = bucketName,
                Key = keyName,
                UseChunkEncoding = false,  // <<<<<<
            };
            client.PutObject(request);
