我正在尝试使用适用于 .NET 的 AWS S3 API 在 apache OZone 中创建密钥。

我尝试创建的密钥必须位于我使用 AWS S3 CLI 创建的名为“test”的存储桶中。

我的代码:

    static async Task WriteFile()
    {
        AmazonS3Config config = new AmazonS3Config();
        config.ServiceURL = "http://myApacheOzoneEndpoint:8744"; // This port is mapped from a docker container to (not the original endpoint port for Ozone)

        AWSCredentials credentials = new BasicAWSCredentials("testuser/scm@EXAMPLE.COM", "c261b6ecabf7d37d5f9ded654b1c724adac9bd9f13e247a235e567e8296d2999"); // Credentials must be set but can be random since Ozone doesn't use authentication
        AmazonS3Client client = new AmazonS3Client(credentials, config);

        using (FileStream fs = File.OpenRead(@"C:\Users\me\path.to.file\image.jpg"))
        {
            string responseBody = "";
            try
            {
                PutObjectRequest request = new PutObjectRequest
                {

                    BucketName = "test",
                    Key = "deleteme.jpg",
                    InputStream = fs
                };

                PutObjectResponse response = await client.PutObjectAsync(request);
                Console.WriteLine($"Result: {response.HttpStatusCode.ToString()}");
            }
            catch (AmazonS3Exception e)
            {
                Console.WriteLine("Error encountered ***. Message:'{0}' when writing an object", e.Message);
            }
            catch (Exception e)
            {
                Console.WriteLine("Unknown encountered on server. Message:'{0}' when writing an object", e.Message);
            }
        }
    }

此代码返回 200 代码错误(OK),如果我从 API 调用 GetObjectAsync,我会得到一个带有元数据的 HTML(但目前无法读取文件内容)

然后我去 Apache Ozone 并在臭氧外壳中执行这些命令:

bash-4.2$ ozone s3  path test
Volume name for S3Bucket is : s3c89e813c80ffcea9543004d57b2a1239
Ozone FileSystem Uri is : o3fs://test.s3c89e813c80ffcea9543004d57b2a1239
bash-4.2$ ozone sh bucket list /s3c89e813c80ffcea9543004d57b2a1239
[ {
  "volumeName" : "s3c89e813c80ffcea9543004d57b2a1239",
  "bucketName" : "test",
  "createdOn" : "Wed, 01 Apr 2020 08:06:40 GMT",
  "acls" : null,
  "versioning" : "DISABLED",
  "storageType" : "DISK",
  "encryptionKeyName" : "N/A"
}, {
  "volumeName" : "s3c89e813c80ffcea9543004d57b2a1239",
  "bucketName" : "deleteme.jpg",
  "createdOn" : "Tue, 31 Mar 2020 10:57:26 GMT",
  "acls" : null,
  "versioning" : "DISABLED",
  "storageType" : "DISK",
  "encryptionKeyName" : "N/A"
} ]
bash-4.2$ ozone sh key list /s3c89e813c80ffcea9543004d57b2a1239/test => This command returns only keys that have been put from AWS S3 CLI

如您所见,该对象被创建为用于 S3 的 Ozone 卷内的新存储桶,而不是作为test存储桶下方的新键创建的。如果我尝试从 AWS S3 Cli 放置密钥,它会按预期工作

怎么了?

仅供参考,我从 Java API 做了同样的例子,同样的问题发生了!

谢谢

Ozone s3-gateway 默认使用路径式寻址,而更新的 sdk 库使用虚拟托管寻址。最快的解决方案是切换到路径样式:

// AmazonS3Config config = new AmazonS3Config();
config.ForcePathStyle = true;

或者,如文档中所述,您可以在臭氧中启用虚拟托管模式。

请注意,路径样式将在 aws s3中被弃用。
