Amazon Aurora DSQL での認証トークンの生成

aws dsql generate-db-connect-admin-auth-token \
  --region region \
  --expires-in 3600 \
  --hostname your_cluster_endpoint

aws dsql generate-db-connect-admin-auth-token ^
  --region=region ^
  --expires-in=3600 ^
  --hostname=your_cluster_endpoint

次の方法でトークンを生成できます。

def generate_token(your_cluster_endpoint, region):
    client = boto3.client("dsql", region_name=region)
    # use `generate_db_connect_auth_token` instead if you are not connecting as admin.
    token = client.generate_db_connect_admin_auth_token(your_cluster_endpoint, region)
    print(token)
    return token

次の方法でトークンを生成できます。

#include <aws/core/Aws.h>
#include <aws/dsql/DSQLClient.h>
#include <iostream>

using namespace Aws;
using namespace Aws::DSQL;

std::string generateToken(String yourClusterEndpoint, String region) {
    Aws::SDKOptions options;
    Aws::InitAPI(options);
    DSQLClientConfiguration clientConfig;
    clientConfig.region = region;
    DSQLClient client{clientConfig};
    std::string token = "";
    
    // If you are not using the admin role to connect, use GenerateDBConnectAuthToken instead
    const auto presignedString = client.GenerateDBConnectAdminAuthToken(yourClusterEndpoint, region);
    if (presignedString.IsSuccess()) {
        token = presignedString.GetResult();
    } else {
        std::cerr << "Token generation failed." << std::endl;
    }

    std::cout << token << std::endl;

    Aws::ShutdownAPI(options);
    return token;
}

次の方法でトークンを生成できます。

import { DsqlSigner } from "@aws-sdk/dsql-signer";

async function generateToken(yourClusterEndpoint, region) {
  const signer = new DsqlSigner({
    hostname: yourClusterEndpoint,
    region,
  });
  try {
    // Use `getDbConnectAuthToken` if you are _not_ logging in as the `admin` user
    const token = await signer.getDbConnectAdminAuthToken();
    console.log(token);
    return token;
  } catch (error) {
      console.error("Failed to generate token: ", error);
      throw error;
  }
}

次の方法でトークンを生成できます。

import software.amazon.awssdk.auth.credentials.DefaultCredentialsProvider;
import software.amazon.awssdk.services.dsql.DsqlUtilities;
import software.amazon.awssdk.regions.Region;

public class GenerateAuthToken { 
    public static String generateToken(String yourClusterEndpoint, Region region) {
        DsqlUtilities utilities = DsqlUtilities.builder()
                .region(region)
                .credentialsProvider(DefaultCredentialsProvider.create())
                .build();

        // Use `generateDbConnectAuthToken` if you are _not_ logging in as `admin` user 
        String token = utilities.generateDbConnectAdminAuthToken(builder -> {
            builder.hostname(yourClusterEndpoint)
                    .region(region);
        });

        System.out.println(token);
        return token;
    }
}

次の方法でトークンを生成できます。

use aws_config::{BehaviorVersion, Region};
use aws_sdk_dsql::auth_token::{AuthTokenGenerator, Config};

async fn generate_token(your_cluster_endpoint: String, region: String) -> String {
    let sdk_config = aws_config::load_defaults(BehaviorVersion::latest()).await;
    let signer = AuthTokenGenerator::new(
        Config::builder()
            .hostname(&your_cluster_endpoint)
            .region(Region::new(region))
            .build()
            .unwrap(),
    );

    // Use `db_connect_auth_token` if you are _not_ logging in as `admin` user
    let token = signer.db_connect_admin_auth_token(&sdk_config).await.unwrap();
    println!("{}", token);
    token.to_string()
}

次の方法でトークンを生成できます。

require 'aws-sdk-dsql'

def generate_token(your_cluster_endpoint, region)
  credentials = Aws::SharedCredentials.new()

  begin
      token_generator = Aws::DSQL::AuthTokenGenerator.new({
          :credentials => credentials
      })
      
      # if you're not using admin role, use generate_db_connect_auth_token instead
      token = token_generator.generate_db_connect_admin_auth_token({
          :endpoint => your_cluster_endpoint,
          :region => region
      })
  rescue => error
    puts error.full_message
  end
end

次の方法でトークンを生成できます。

次の例では、DSQLAuthTokenGenerator ユーティリティクラスを使用して、admin ロールを持つユーザーの認証トークンを生成します。insert-dsql-cluster-endpoint をクラスターエンドポイントに置き換えます。

using Amazon;
using Amazon.DSQL.Util;
using Amazon.Runtime;

var yourClusterEndpoint = "insert-dsql-cluster-endpoint";

AWSCredentials credentials = FallbackCredentialsFactory.GetCredentials();

var token = DSQLAuthTokenGenerator.GenerateDbConnectAdminAuthToken(credentials, RegionEndpoint.USEast1, yourClusterEndpoint);

Console.WriteLine(token);

次のコード例では、PostgreSQL ユーザーに基づいて action を指定します。

次の例では、yourClusterEndpoint とリージョンに加えて、アクションを使用します。PostgreSQL ユーザーに基づいてアクションを指定します。

func GenerateDbConnectAdminAuthToken(yourClusterEndpoint string, region string, action string) (string, error) {
	// Fetch credentials
	sess, err := session.NewSession()
	if err != nil {
		return "", err
	}

	creds, err := sess.Config.Credentials.Get()
	if err != nil {
		return "", err
	}
	staticCredentials := credentials.NewStaticCredentials(
		creds.AccessKeyID,
		creds.SecretAccessKey,
		creds.SessionToken,
	)

	// The scheme is arbitrary and is only needed because validation of the URL requires one.
	endpoint := "https://" + yourClusterEndpoint
	req, err := http.NewRequest("GET", endpoint, nil)
	if err != nil {
		return "", err
	}
	values := req.URL.Query()
	values.Set("Action", action)
	req.URL.RawQuery = values.Encode()

	signer := v4.Signer{
		Credentials: staticCredentials,
	}
	_, err = signer.Presign(req, nil, "dsql", region, 15*time.Minute, time.Now())
	if err != nil {
		return "", err
	}

	url := req.URL.String()[len("https://"):]

	return url, nil
}
