要通过 GetLatestConfiguration API 访问 AWS AppConfig 中的特征标志配置,可以使用 AWS SDK for Java,并按照以下步骤操作:
import com.amazonaws.services.appconfig.AWSAppConfig; import com.amazonaws.services.appconfig.AWSAppConfigClientBuilder; import com.amazonaws.services.appconfig.model.GetConfigurationRequest; import com.amazonaws.services.appconfig.model.GetConfigurationResult; import com.amazonaws.services.appconfig.model.ResourceNotFoundException;
public class App { public static void main(String args[]) { final String application = "my-app"; final String environment = "prod"; final String configuration = "my-config"; final String client_id = "123";
AWSAppConfig client = AWSAppConfigClientBuilder.standard().build();
GetConfigurationRequest request = new GetConfigurationRequest()
.withApplication(application)
.withEnvironment(environment)
.withConfiguration(configuration)
.withClientId(client_id);
GetConfigurationResult response = null;
try {
response = client.getConfiguration(request);
} catch (ResourceNotFoundException e) {
System.out.println("Configuration not found: " + e.getMessage());
System.exit(1);
}
//response.getCodeConfiguration() returns an object of AWS AppConfig ConfigurationData type
//Call getCodeConfiguration() method of GetConfigurationResult class to get the configuration data
System.out.println(response.getCodeConfiguration().getContent());
}
}
上述代码示例中,我们使用了 AWS SDK for Java 和 GetLatestConfiguration API 获取了 AWS AppConfig 中的特征标志配置。我们使用 getConfiguration() 方法向 GetLatestConfiguration API 发送了一个 GetConfigurationRequest,并从 GetConfigurationResult 类中获取了特征标志配置。
注意:为了使用上述代码示例,您需要安装 AWS SDK for Java,并配置您的 AWS 访问凭据。
