使用适用于 .NET 的 AWS SDK 上传到 Google Cloud Storage`预期哈希不等于计算哈希`

问题描述

我正在尝试使用适用于 .NET 的 AWS SDK 上传到 Google Cloud Storage。我在 GCS 上启用了互操作模式并将 AWSSecretKey 和 AWSAccessKey 放在我的 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);

但我得到的结果是：

相同的代码在 S3 上运行正常（减去设置 ServiceURL）

解决方法

GCS 文档说：

在 Cloud Storage XML API 中，目前无法同时使用分块传输编码和 V4 签名。一些 Amazon S3 工具默认使用分块传输编码和签名；在这种情况下，您应该禁用分块传输编码。

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);
