google-cloud-storage - 使用适用于 .NET 的 AWS SDK 上传到 Google Cloud Storage `预期的哈希值不等于计算的哈希值`

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。

我正在使用的代码是

            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：

相同的代码适用于 S3（减去设置 ServiceURL）

解决方案

GCS 文档说：

在 Cloud Storage XML API 中，分块传输编码和 V4 签名目前不能同时使用。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。

我发现要解决这个错误，我需要添加UseChunkEncoding = false到 PutObjectRequest：

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