如何检索 AWS Secrets Manager 密钥的特定值？

Question

我有这个 java 代码可以从秘密中检索值：

public class fetchSecrets {
    public static void main(String[] args) {
        String secretId = "test";
        SecretsManagerClient secretsClient = SecretsManagerClient.builder()
                .region(Region.EU_WEST_1)
                .build();
        fetchPassword(secretsClient, secretId);
        secretsClient.close();
    }

    public static void fetchPassword(SecretsManagerClient secretsClient, String secretId) {
        try {
            GetSecretValueRequest valueRequest = GetSecretValueRequest.builder()
                .secretId(secretId)
                .build();
            GetSecretValueResponse valueResponse = secretsClient.getSecretValue(valueRequest);
            String secret = valueResponse.secretString();
            System.out.println(secret);
        } catch (SecretsManagerException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }
}

当我运行这段代码时，我得到：

{"username":"test","password":"password123456"}

如何仅输出密码或用户名密钥的值？

所以预期的输出是例如password123456

Answer 1

我建议执行以下操作：首先，像这样创建一个名为 User 的 class：

public class User {

    private String username;
    private String  password;

    //setter
    void setUsername(String username) {
        this.username = username;
    }

    void setPassword(String password) {
        this.password = password;
    }

    //getter
    String getUsername(){
        return this.username;
    }

    String getPassword(){
        return this.password;
    }
}

然后您可以像这样找回密码：

User user = gson.fromJson(secret , User.class);
System.out.println(user.getPassword());

Answer 2

原来我必须创建一个 json 对象并传入字符串以提取其值：

try {
    GetSecretValueRequest request = GetSecretValueRequest.builder()
           .secretId(secretId)
           .build();

    GetSecretValueResponse valueResponse = secretsClient.getSecretValue(request);
    String secret = valueResponse.secretString();

    //defining a JSON string     
    Object obj = JSONValue.parse(secret); 
   
    //creating an object of JSONObject class
    //and casting the object into JSONObject type  
    JSONObject jsonObject = (JSONObject) obj;   
 
    //getting values form the JSONObject
    //and casting that values into corresponding types  
    String username = (String) jsonObject.get("username");    

    //printing the values   
    System.out.println(username); 

} catch (SecretsManagerException e) {
    System.err.println(e.awsErrorDetails().errorMessage());
    System.exit(1);
}

输出：password123456
