Apache Ozone + AWS S3 .Net API:PutObject正在创建存储桶而不是密钥

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

我要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(确定),如果我从API调用GetObjectAsync,我将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并在臭氧外壳内执行以下命令:

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,该对象在用于S3的Ozone体积内创建为新存储桶,而不是在test存储桶下创建为新键。如果我尝试放置来自AWS S3 Cli的密钥,它将按预期工作

发生了什么事?

仅供参考,我从Java API制作了相同的示例,并且发生了相同的问题!

谢谢

默认情况下,臭氧s3-gateway使用path-style addressing,而更新的sdk库则使用虚拟主机寻址。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主机架构。

请注意,aws s3中的路径样式is going to be deprecated
