AWS Elasticsearch Service - 手动快照到 S3

Question

我尝试创建我的"Amazon Elasticsearch Service"的手动快照我找到了此文档，但在最后一步注册快照存储库时遇到问题。我搜索 .net 的解决方案，但此示例是一个 python 脚本，我找不到 .net 的解决方案

是否有可用于对 c# 请求进行签名的解决方案？

用于签署请求的 Phyton 脚本

from boto.connection import AWSAuthConnection
class ESConnection(AWSAuthConnection):
    def __init__(self, region, **kwargs):
        super(ESConnection, self).__init__(**kwargs)
        self._set_auth_region_name(region)
        self._set_auth_service_name("es")
    def _required_auth_capability(self):
        return ['hmac-v4']
if __name__ == "__main__":
    client = ESConnection(
            region='eu-west-1',
            host='search-domain.eu-west-1.es.amazonaws.com',
            profile_name='ifOtherThanDefault',
            is_secure=False)
    print 'Registering Snapshot Repository'
    resp = client.make_request(method='PUT',
            path='/_snapshot/es-index-backups',
            data='{"type": "s3","settings": { "bucket": "my-es-snapshot-repo","region": "eu-west-1","role_arn": "arn:aws:iam::123456789012:role/es-snapshots-role"}}')
    body = resp.read()
    print body

C# 解决方案

Amazon Requests (AWSSDK.身份管理(

//Change the bucket to the correct bucket
var s3BucketName = "test.elasticsearch";
createPolicyJson = createPolicyJson.Replace("my-es-snapshot-repo", s3BucketName);

var awsCredentials = new BasicAWSCredentials("accessKey", "secretKey");
var client = new AmazonIdentityManagementServiceClient(awsCredentials, Amazon.RegionEndpoint.EUCentral1);

var responseCreateRole = client.CreateRole(createRoleRequest);
var responseCreatePolicy = client.CreatePolicy(createPolicyRequest);
var responseAttachRolePolicy = client.AttachRolePolicy(new AttachRolePolicyRequest { PolicyArn = responseCreatePolicy.Policy.Arn, RoleName = responseCreateRole.Role.RoleName });
