凭据管家客户端 - 密钥管理服务

凭据管家客户端（SecretsManager Client）基于KMS凭据管家API封装了业务逻辑、最佳实践和设计模式，更易于开发者在业务系统中集成。主要适用于应用中动态使用托管在凭据管家中的凭据，告别对敏感信息的硬编码。

功能特性

凭据管家客户端具有以下功能特性：

支持开发者在应用中快速集成凭据管家能力，一行代码读取凭据信息。
封装凭据在应用中缓存和刷新的功能。
封装API错误的重试机制，智能处理服务端错误。
开放插件式设计模式，支持开发者自定义扩展缓存、错误重试等功能模块。

凭据管家Java客户端

安装SDK

凭据管家客户端支持Java语言，您可以访问SecretsManager Client for Java开源代码仓库了解更多代码信息。

您可以通过Maven在项目中使用凭据管家Java客户端，需要添加的依赖信息如下：

<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>alibabacloud-secretsmanager-client</artifactId>
    <version>x.x.x</version>
</dependency>

说明凭据管家Java客户端具体版本，请参见alibabacloud-secretsmanager-client-java。

示例代码

通过配置文件（secretsmanager.properties）构建客户端

建议您采用基于Client Key的应用接入点，通过凭据管家Java SDK使用Client Key。关于如何创建Client Key，请参见为AAP绑定Client Key。

凭据管家Java客户端在1.1.8及以上版本支持基于Client Key应用接入点访问凭据管家，需要配置以下配置文件：

## 配置访问方式。
credentials_type=client_key

## 读取Client Key的解密密码：支持从环境变量或者文件读取。
client_key_password_from_env_variable=#your client key private key password environment variable name#
client_key_password_from_file_path=#your client key private key password file path#

## 获取Client Key的私钥文件。
client_key_private_key_path=#your client key private key file path#

## 配置关联的KMS地域。
cache_client_region_id=[{"regionId":"#regionId#"}]

通过配置文件（secretsmanager.properties）构建客户端的示例代码如下：

import com.aliyuncs.kms.secretsmanager.client.SecretCacheClient;
import com.aliyuncs.kms.secretsmanager.client.SecretCacheClientBuilder;
import com.aliyuncs.kms.secretsmanager.client.exception.CacheSecretException;
import com.aliyuncs.kms.secretsmanager.client.model.SecretInfo;

public class CacheClientEnvironmentSample {

    public static void main(String[] args) {
        try {
            SecretCacheClient client = SecretCacheClientBuilder.newClient();
            SecretInfo secretInfo = client.getSecretInfo("#secretName#");
            System.out.println(secretInfo);
        } catch (CacheSecretException e) {
            e.printStackTrace();
        }
    }
}

通过指定参数（Access Key、Access Secret、RegionID等）构建客户端

import com.aliyuncs.kms.secretsmanager.client.SecretCacheClient;
import com.aliyuncs.kms.secretsmanager.client.SecretCacheClientBuilder;
import com.aliyuncs.kms.secretsmanager.client.exception.CacheSecretException;
import com.aliyuncs.kms.secretsmanager.client.model.SecretInfo;
import com.aliyuncs.kms.secretsmanager.client.service.BaseSecretManagerClientBuilder;
import com.aliyuncs.kms.secretsmanager.client.utils.CredentialsProviderUtils;

public class CacheClientSimpleParametersSample {

    public static void main(String[] args) {
        try {
            SecretCacheClient client = SecretCacheClientBuilder.newCacheClientBuilder(
                    BaseSecretManagerClientBuilder.standard().withCredentialsProvider(CredentialsProviderUtils
                            .withAccessKey("#accessKeyId#", "#accessKeySecret#")).withRegion("#regionId#").build()).build();
            SecretInfo secretInfo = client.getSecretInfo("#secretName#");
            System.out.println(secretInfo);
        } catch (CacheSecretException e) {
            e.printStackTrace();
        }
    }
}

通过自定义参数构建客户端

import com.aliyuncs.kms.secretsmanager.client.SecretCacheClient;
import com.aliyuncs.kms.secretsmanager.client.SecretCacheClientBuilder;
import com.aliyuncs.kms.secretsmanager.client.cache.FileCacheSecretStoreStrategy;
import com.aliyuncs.kms.secretsmanager.client.exception.CacheSecretException;
import com.aliyuncs.kms.secretsmanager.client.model.SecretInfo;
import com.aliyuncs.kms.secretsmanager.client.service.BaseSecretManagerClientBuilder;
import com.aliyuncs.kms.secretsmanager.client.service.DefaultRefreshSecretStrategy;
import com.aliyuncs.kms.secretsmanager.client.service.FullJitterBackoffStrategy;
import com.aliyuncs.kms.secretsmanager.client.utils.CredentialsProviderUtils;

public class CacheClientDetailParametersSample {

    public static void main(String[] args) {
        try {
            SecretCacheClient client = SecretCacheClientBuilder.newCacheClientBuilder(BaseSecretManagerClientBuilder.standard()
                    .withCredentialsProvider(CredentialsProviderUtils.withAccessKey("#accessKeyId#", "#accessKeySecret#"))
                    .withRegion("#regionId#")
                    .withBackoffStrategy(new FullJitterBackoffStrategy(3, 2000, 10000)).build())
                    .withCacheSecretStrategy(new FileCacheSecretStoreStrategy("#cacheSecretPath#", true, "#salt#"))
                    .withRefreshSecretStrategy(new DefaultRefreshSecretStrategy("#ttlName#"))
                    .withCacheStage("#stage#")
                    .withSecretTTL("#secretName#", 1 * 60 * 1000l)
                    .withSecretTTL("#secretName1#", 2 * 60 * 1000l).build();
            SecretInfo secretInfo = client.getSecretInfo("#secretName#");
            System.out.println(secretInfo);
        } catch (CacheSecretException e) {
            e.printStackTrace();
        }
    }
