# Escenarios de uso CloudFront AWS SDKs
<a name="cloudfront_code_examples_scenarios"></a>

Los siguientes ejemplos de código muestran cómo implementar escenarios comunes en CloudFront with AWS SDKs. Estos escenarios muestran cómo realizar tareas específicas mediante la invocación de varias funciones internas CloudFront o combinadas con otras Servicios de AWS. En cada escenario se incluye un enlace al código fuente completo, con instrucciones de configuración y ejecución del código. 

Los escenarios requieren un nivel intermedio de experiencia para entender las acciones de servicio en su contexto.

 Hay más en marcha GitHub. Busque el ejemplo completo y aprenda a configurar y ejecutar en el [Repositorio de ejemplos de código de AWS](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javav2/example_code/cloudfront#code-examples). 
El siguiente ejemplo demuestra cómo crear una distribución de varios inquilino con parámetros y un certificado comodín.

En el siguiente ejemplo, se muestra cómo hacerlo con una solicitud de certificado CloudFront gestionada alojada. Esto es ideal si aún no tiene tráfico hacia el dominio. En este caso, creamos un ConnectionGroup para generar un RoutingEndpoint. Luego lo usamos RoutingEndpoint para crear registros DNS que verifican la propiedad del dominio y apuntan a CloudFront. CloudFront luego, entregará automáticamente un token para validar la propiedad del dominio y crear un certificado administrado.

El siguiente ejemplo demuestra cómo hacerlo con una solicitud de certificado autoadministrada. Esto es ideal si tiene tráfico hacia el dominio y no puede tolerar el tiempo de inactividad durante una migración. Al final de este ejemplo, el inquilino se creará con un estado de espera de la validación del dominio y la configuración de DNS. Siga los pasos [aquí] (https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/managed-cloudfront-certificates.html\$1complete-domain-ownership) para completar la configuración cuando esté listo para migrar el tráfico.

# Comience con una CloudFront distribución básica mediante la CLI
<a name="cloudfront_example_cloudfront_GettingStarted_section"></a>

En el siguiente ejemplo de código, se muestra cómo:
+ Creación de un bucket de Amazon S3 para el almacenamiento de contenido
+ Carga del contenido de ejemplo en el bucket de S3
+ Creación de un control de acceso de origen (OAC) para el acceso seguro a S3
+ Cree una CloudFront distribución con S3 como origen
+ Actualice la política de buckets de S3 para permitir el CloudFront acceso
+ Espera para la implementación de la distribución y prueba del acceso al contenido
+ Eliminación de los recursos, incluidos la distribución, el OAC y el bucket de S3

# Crea cookies URLs y firmadas mediante un AWS SDK
<a name="cloudfront_example_cloudfront_CloudFrontUtilities_section"></a>

El siguiente ejemplo de código muestra cómo crear cookies firmadas URLs y cookies que permitan el acceso a recursos restringidos.

------
#### [ Java ]

**SDK para Java 2.x**  
 Hay más información al respecto GitHub. Busque el ejemplo completo y aprenda a configurar y ejecutar en el [Repositorio de ejemplos de código de AWS](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javav2/example_code/cloudfront#code-examples). 
Usa la [CannedSignerRequest](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudfront/model/CannedSignerRequest.html)clase para firmar URLs o usar cookies con una *política* estándar.  

```
import software.amazon.awssdk.services.cloudfront.model.CannedSignerRequest;

import java.net.URL;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.time.Instant;
import java.time.temporal.ChronoUnit;

public class CreateCannedPolicyRequest {

    public static CannedSignerRequest createRequestForCannedPolicy(String distributionDomainName,
            String fileNameToUpload,
            String privateKeyFullPath, String publicKeyId) throws Exception {
        String protocol = "https";
        String resourcePath = "/" + fileNameToUpload;

        String cloudFrontUrl = new URL(protocol, distributionDomainName, resourcePath).toString();
        Instant expirationDate = Instant.now().plus(7, ChronoUnit.DAYS);
        Path path = Paths.get(privateKeyFullPath);

        return CannedSignerRequest.builder()
                .resourceUrl(cloudFrontUrl)
                .privateKey(path)
                .keyPairId(publicKeyId)
                .expirationDate(expirationDate)
                .build();
    }
}
```
Usa la [CustomSignerRequest](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudfront/model/CustomSignerRequest.html)clase para firmar URLs o usar cookies con una política *personalizada*. `activeDate` y `ipRange` son métodos opcionales.  

```
import software.amazon.awssdk.services.cloudfront.model.CustomSignerRequest;

import java.net.URL;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.time.Instant;
import java.time.temporal.ChronoUnit;

public class CreateCustomPolicyRequest {

    public static CustomSignerRequest createRequestForCustomPolicy(String distributionDomainName,
            String fileNameToUpload,
            String privateKeyFullPath, String publicKeyId) throws Exception {
        String protocol = "https";
        String resourcePath = "/" + fileNameToUpload;

        String cloudFrontUrl = new URL(protocol, distributionDomainName, resourcePath).toString();
        Instant expireDate = Instant.now().plus(7, ChronoUnit.DAYS);
        // URL will be accessible tomorrow using the signed URL.
        Instant activeDate = Instant.now().plus(1, ChronoUnit.DAYS);
        Path path = Paths.get(privateKeyFullPath);

        return CustomSignerRequest.builder()
                .resourceUrl(cloudFrontUrl)
                // .resourceUrlPattern("https://*.example.com/*")  // Optional.
                .privateKey(path)
                .keyPairId(publicKeyId)
                .expirationDate(expireDate)
                .activeDate(activeDate) // Optional.
                // .ipRange("192.168.0.1/24") // Optional.
                .build();
    }
}
```
El siguiente ejemplo demuestra el uso de la [CloudFrontUtilities](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/cloudfront/CloudFrontUtilities.html)clase para producir cookies firmadas y URLs.
