#### [ JavaScript ]
**SDK para JavaScript (v3)**
Hay más información. 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/javascriptv3/example_code/s3#code-examples).
Primero, importe todos los módulos necesarios.
```
// Used to check if currently running file is this file.
import { fileURLToPath } from "node:url";
import { readdirSync, readFileSync, writeFileSync } from "node:fs";
// Local helper utils.
import { dirnameFromMetaUrl } from "@aws-doc-sdk-examples/lib/utils/util-fs.js";
import { Prompter } from "@aws-doc-sdk-examples/lib/prompter.js";
import { wrapText } from "@aws-doc-sdk-examples/lib/utils/util-string.js";
import {
S3Client,
CreateBucketCommand,
PutObjectCommand,
ListObjectsCommand,
CopyObjectCommand,
GetObjectCommand,
DeleteObjectsCommand,
DeleteBucketCommand,
} from "@aws-sdk/client-s3";
```
Las importaciones anteriores hacen referencia a algunas utilidades auxiliares. Estas utilidades son locales del GitHub repositorio vinculado al principio de esta sección. Consulte las siguientes implementaciones de esas utilidades a modo de referencia.
```
export const dirnameFromMetaUrl = (metaUrl) =>
fileURLToPath(new URL(".", metaUrl));
import { select, input, confirm, checkbox, password } from "@inquirer/prompts";
export class Prompter {
/**
* @param {{ message: string, choices: { name: string, value: string }[]}} options
*/
select(options) {
return select(options);
}
/**
* @param {{ message: string }} options
*/
input(options) {
return input(options);
}
/**
* @param {{ message: string }} options
*/
password(options) {
return password({ ...options, mask: true });
}
/**
* @param {string} prompt
*/
checkContinue = async (prompt = "") => {
const prefix = prompt && `${prompt} `;
const ok = await this.confirm({
message: `${prefix}Continue?`,
});
if (!ok) throw new Error("Exiting...");
};
/**
* @param {{ message: string }} options
*/
confirm(options) {
return confirm(options);
}
/**
* @param {{ message: string, choices: { name: string, value: string }[]}} options
*/
checkbox(options) {
return checkbox(options);
}
}
export const wrapText = (text, char = "=") => {
const rule = char.repeat(80);
return `${rule}\n ${text}\n${rule}\n`;
};
```
Los objetos se almacenan en «cubos». Definamos una función para crear un nuevo bucket.
```
export const createBucket = async () => {
const bucketName = await prompter.input({
message: "Enter a bucket name. Bucket names must be globally unique:",
});
const command = new CreateBucketCommand({ Bucket: bucketName });
await s3Client.send(command);
console.log("Bucket created successfully.\n");
return bucketName;
};
```
Los buckets contienen «objetos». Esta función carga el contenido de un directorio al bucket en forma de objetos.
```
export const uploadFilesToBucket = async ({ bucketName, folderPath }) => {
console.log(`Uploading files from ${folderPath}\n`);
const keys = readdirSync(folderPath);
const files = keys.map((key) => {
const filePath = `${folderPath}/${key}`;
const fileContent = readFileSync(filePath);
return {
Key: key,
Body: fileContent,
};
});
for (const file of files) {
await s3Client.send(
new PutObjectCommand({
Bucket: bucketName,
Body: file.Body,
Key: file.Key,
}),
);
console.log(`${file.Key} uploaded successfully.`);
}
};
```
Después de cargar los objetos, confirme que se hayan subido correctamente. Puedes usarlos ListObjects para eso. Utilizará la propiedad «Clave», pero también hay otras propiedades útiles en la respuesta.
```
export const listFilesInBucket = async ({ bucketName }) => {
const command = new ListObjectsCommand({ Bucket: bucketName });
const { Contents } = await s3Client.send(command);
const contentsList = Contents.map((c) => ` • ${c.Key}`).join("\n");
console.log("\nHere's a list of files in the bucket:");
console.log(`${contentsList}\n`);
};
```
A veces, es posible que quiera copiar un objeto de un bucket en otro bucket. Usa el CopyObject comando para eso.
```
export const copyFileFromBucket = async ({ destinationBucket }) => {
const proceed = await prompter.confirm({
message: "Would you like to copy an object from another bucket?",
});
if (!proceed) {
return;
}
const copy = async () => {
try {
const sourceBucket = await prompter.input({
message: "Enter source bucket name:",
});
const sourceKey = await prompter.input({
message: "Enter source key:",
});
const destinationKey = await prompter.input({
message: "Enter destination key:",
});
const command = new CopyObjectCommand({
Bucket: destinationBucket,
CopySource: `${sourceBucket}/${sourceKey}`,
Key: destinationKey,
});
await s3Client.send(command);
await copyFileFromBucket({ destinationBucket });
} catch (err) {
console.error("Copy error.");
console.error(err);
const retryAnswer = await prompter.confirm({ message: "Try again?" });
if (retryAnswer) {
await copy();
}
}
};
await copy();
};
```
No existe ningún método de SDK para obtener varios objetos de un bucket. En su lugar, creará una lista de objetos para descargarlos e iterarlos.
```
export const downloadFilesFromBucket = async ({ bucketName }) => {
const { Contents } = await s3Client.send(
new ListObjectsCommand({ Bucket: bucketName }),
);
const path = await prompter.input({
message: "Enter destination path for files:",
});
for (const content of Contents) {
const obj = await s3Client.send(
new GetObjectCommand({ Bucket: bucketName, Key: content.Key }),
);
writeFileSync(
`${path}/${content.Key}`,
await obj.Body.transformToByteArray(),
);
}
console.log("Files downloaded successfully.\n");
};
```
Ha llegado el momento de limpiar los recursos. Un bucket debe estar vacío para poder eliminarlo. Estas dos funciones vacían y eliminan el bucket.
```
export const emptyBucket = async ({ bucketName }) => {
const listObjectsCommand = new ListObjectsCommand({ Bucket: bucketName });
const { Contents } = await s3Client.send(listObjectsCommand);
const keys = Contents.map((c) => c.Key);
const deleteObjectsCommand = new DeleteObjectsCommand({
Bucket: bucketName,
Delete: { Objects: keys.map((key) => ({ Key: key })) },
});
await s3Client.send(deleteObjectsCommand);
console.log(`${bucketName} emptied successfully.\n`);
};
export const deleteBucket = async ({ bucketName }) => {
const command = new DeleteBucketCommand({ Bucket: bucketName });
await s3Client.send(command);
console.log(`${bucketName} deleted successfully.\n`);
};
```
La función «principal» reúne todo. Si ejecuta este archivo directamente, se llamará a la función principal.
```
const main = async () => {
const OBJECT_DIRECTORY = `${dirnameFromMetaUrl(
import.meta.url,
)}../../../../resources/sample_files/.sample_media`;
try {
console.log(wrapText("Welcome to the Amazon S3 getting started example."));
console.log("Let's create a bucket.");
const bucketName = await createBucket();
await prompter.confirm({ message: continueMessage });
console.log(wrapText("File upload."));
console.log(
"I have some default files ready to go. You can edit the source code to provide your own.",
);
await uploadFilesToBucket({
bucketName,
folderPath: OBJECT_DIRECTORY,
});
await listFilesInBucket({ bucketName });
await prompter.confirm({ message: continueMessage });
console.log(wrapText("Copy files."));
await copyFileFromBucket({ destinationBucket: bucketName });
await listFilesInBucket({ bucketName });
await prompter.confirm({ message: continueMessage });
console.log(wrapText("Download files."));
await downloadFilesFromBucket({ bucketName });
console.log(wrapText("Clean up."));
await emptyBucket({ bucketName });
await deleteBucket({ bucketName });
} catch (err) {
console.error(err);
}
};

# Acciones para Amazon S3 mediante AWS SDKs
Los siguientes ejemplos de código muestran cómo realizar acciones individuales de Amazon S3 con AWS SDKs. Cada ejemplo incluye un enlace a GitHub, donde puede encontrar instrucciones para configurar y ejecutar el código.
Estos fragmentos llaman a la API de Amazon S3 y son fragmentos de código de programas más grandes que deben ejecutarse en contexto. Puede ver las acciones en contexto en [Escenarios para el uso de Amazon S3 AWS SDKs](s3_code_examples_scenarios.md).
Los siguientes ejemplos incluyen solo las acciones que se utilizan con mayor frecuencia. Para obtener una lista completa, consulte la [Referencia de la API de Amazon Simple Storage Service](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html).

#### [ CLI ]
**AWS CLI**
El siguiente comando completa una carga multiparte de la clave `multipart/01`en el bucket `amzn-s3-demo-bucket`:
```
aws s3api complete-multipart-upload --multipart-upload file://mpustruct --bucket amzn-s3-demo-bucket --key 'multipart/01' --upload-id dfRtDYU0WWCCcH43C3WFbkRONycyCpTJJvxu2i5GYkZljF.Yxwh6XG7WfS2vC4to6HiV6Yjlx.cph0gtNBtJ8P3URCSbB7rjxI5iEwVDmgaXZOGgkk5nVTW16HOQ5l0R
```
El ID de carga requerido por este comando se genera mediante `create-multipart-upload` y también se puede recuperar con `list-multipart-uploads`.
La opción de carga multiparte del comando anterior utiliza una estructura JSON que describe las partes de la carga multiparte que se deben volver a ensamblar en el archivo completo. En este ejemplo, el prefijo `file://` se usa para cargar la estructura JSON desde un archivo de la carpeta local denominada `mpustruct`.
mpustruct:
```
{
"Parts": [
{
"ETag": "e868e0f4719e394144ef36531ee6824c",
"PartNumber": 1
},
{
"ETag": "6bb2b12753d66fe86da4998aa33fffb0",
"PartNumber": 2
},
{
"ETag": "d0a0112e841abec9c9ec83406f0159c8",
"PartNumber": 3
}
]
}
```
El ETag valor de cada parte que se carga se muestra cada vez que se carga una parte mediante el `upload-part` comando y también se puede recuperar mediante una llamada `list-parts` o calcularse utilizando la MD5 suma de verificación de cada parte.
Salida:
```
{
"ETag": "\"3944a9f7a4faab7f78788ff6210f63f0-3\"",
"Bucket": "amzn-s3-demo-bucket",
"Location": "https://amzn-s3-demo-bucket.s3.amazonaws.com/multipart%2F01",

#### [ CLI ]
**AWS CLI**
**Ejemplo 1: Creación de un bucket**
En los siguientes ejemplos de `create-bucket` se crea un bucket denominado `amzn-s3-demo-bucket`:
```
aws s3api create-bucket \
--bucket amzn-s3-demo-bucket \
--region us-east-1
```
Salida:
```
{
"Location": "/amzn-s3-demo-bucket"
}
```
Para obtener más información, consulte [Crear un bucket](https://docs.aws.amazon.com/AmazonS3/latest/userguide/create-bucket-overview.html) en la *Guía del usuario de Amazon S3*.
**Ejemplo 2: Creación de un bucket con propietario obligatorio**
En el siguiente ejemplo de `create-bucket` se crea un bucket denominado `amzn-s3-demo-bucket` que utiliza la configuración Aplicada al propietario del bucket de S3 Object Ownership.
```
aws s3api create-bucket \
--bucket amzn-s3-demo-bucket \
--region us-east-1 \
--object-ownership BucketOwnerEnforced
```
Salida:
```
{
"Location": "/amzn-s3-demo-bucket"
}
```

**Ejemplo 3: creación de un bucket fuera de la región us-east-1**
En el siguiente ejemplo `create-bucket`, se crea un bucket denominado `amzn-s3-demo-bucket` en la región `eu-west-1`. Las regiones situadas fuera de `us-east-1` requieren que se especifique el `LocationConstraint` correspondiente para poder crear el bucket en la región deseada.
```
aws s3api create-bucket \
--bucket amzn-s3-demo-bucket \
--region eu-west-1 \
--create-bucket-configuration LocationConstraint=eu-west-1
```

**Herramientas para la PowerShell versión 4**
**Ejemplo 1: este comando elimina el objeto “sample.txt” del bucket “test-files”. Antes de ejecutar el comando, se le solicitará que lo confirme; para suprimir el mensaje, utilice el conmutador -Force.**
```
Remove-S3Object -BucketName amzn-s3-demo-bucket -Key sample.txt
```
**Ejemplo 2: este comando elimina la versión especificada del objeto “sample.txt” del bucket “test-files”, suponiendo que el bucket se haya configurado para habilitar las versiones de los objetos.**
```
Remove-S3Object -BucketName amzn-s3-demo-bucket -Key sample.txt -VersionId HLbxnx6V9omT6AQYVpks8mmFKQcejpqt
```
**Ejemplo 3: este comando elimina los objetos “sample1.txt”, “sample2.txt” y “sample3.txt” del bucket “test-files” como una sola operación por lotes. La respuesta del servicio mostrará una lista de todas las claves procesadas, independientemente del estado de éxito o error de la eliminación. Para obtener únicamente los errores de las claves que el servicio no pudo procesar, añada el ReportErrorsOnly parámetro - (este parámetro también se puede especificar con el alias -Quiet).**
```
Remove-S3Object -BucketName amzn-s3-demo-bucket -KeyCollection @( "sample1.txt", "sample2.txt", "sample3.txt" )
```
**Ejemplo 4: En este ejemplo se utiliza una expresión en línea con el KeyCollection parámetro - para obtener las claves de los objetos que se van a eliminar. Get-S3Objectdevuelve una colección de instancias de Amazon.S3.Model.S3Object, cada una de las cuales tiene un elemento clave del tipo string que identifica** el objeto.
```
Remove-S3Object -bucketname "amzn-s3-demo-bucket" -KeyCollection (Get-S3Object "test-files" -KeyPrefix "prefix/subprefix" | select -ExpandProperty Key)
```
**Ejemplo 5: este ejemplo obtiene todos los objetos que tienen un prefijo de clave “prefijo/subprefijo” en el bucket y los elimina. Tenga en cuenta que los objetos entrantes se procesan de uno en uno. En el caso de colecciones grandes, considere la posibilidad de pasar la colección al parámetro - InputObject (alias -S3ObjectCollection) del cmdlet para permitir que la eliminación se realice por lotes con una sola llamada al servicio.**
```

**Ejemplo 1: este comando elimina el objeto “sample.txt” del bucket “test-files”. Antes de ejecutar el comando, se le solicitará que lo confirme; para suprimir el mensaje, utilice el conmutador -Force.**
```
Remove-S3Object -BucketName amzn-s3-demo-bucket -Key sample.txt
```
**Ejemplo 2: este comando elimina la versión especificada del objeto “sample.txt” del bucket “test-files”, suponiendo que el bucket se haya configurado para habilitar las versiones de los objetos.**
```
Remove-S3Object -BucketName amzn-s3-demo-bucket -Key sample.txt -VersionId HLbxnx6V9omT6AQYVpks8mmFKQcejpqt
```
**Ejemplo 3: este comando elimina los objetos “sample1.txt”, “sample2.txt” y “sample3.txt” del bucket “test-files” como una sola operación por lotes. La respuesta del servicio mostrará una lista de todas las claves procesadas, independientemente del estado de éxito o error de la eliminación. Para obtener únicamente los errores de las claves que el servicio no pudo procesar, añada el ReportErrorsOnly parámetro - (este parámetro también se puede especificar con el alias -Quiet).**
```
Remove-S3Object -BucketName amzn-s3-demo-bucket -KeyCollection @( "sample1.txt", "sample2.txt", "sample3.txt" )
```
**Ejemplo 4: En este ejemplo se utiliza una expresión en línea con el KeyCollection parámetro - para obtener las claves de los objetos que se van a eliminar. Get-S3Objectdevuelve una colección de instancias de Amazon.S3.Model.S3Object, cada una de las cuales tiene un elemento clave del tipo string que identifica** el objeto.
```
Remove-S3Object -bucketname "amzn-s3-demo-bucket" -KeyCollection (Get-S3Object "test-files" -KeyPrefix "prefix/subprefix" | select -ExpandProperty Key)
```
**Ejemplo 5: este ejemplo obtiene todos los objetos que tienen un prefijo de clave “prefijo/subprefijo” en el bucket y los elimina. Tenga en cuenta que los objetos entrantes se procesan de uno en uno. En el caso de colecciones grandes, considere la posibilidad de pasar la colección al parámetro - InputObject (alias -S3ObjectCollection) del cmdlet para permitir que la eliminación se realice por lotes con una sola llamada al servicio.**

```
aws s3api get-object --bucket text-content --key dir/my_images.tar.bz2 my_images.tar.bz2
```
Tenga en cuenta que el parámetro outfile se especifica sin un nombre de opción, como "--outfile". El nombre del archivo de salida debe ser el último parámetro del comando.
El siguiente ejemplo muestra el uso de `--range` para descargar un intervalo de bytes específico de un objeto. Tenga en cuenta que los intervalos de bytes deben tener el prefijo "bytes=":
```
aws s3api get-object --bucket text-content --key dir/my_data --range bytes=8888-9999 my_data_range

#### [ CLI ]
**AWS CLI**
El comando siguiente aplica una configuración del ciclo de vida a un bucket denominado `amzn-s3-demo-bucket`:
```
aws s3api put-bucket-lifecycle-configuration --bucket amzn-s3-demo-bucket --lifecycle-configuration file://lifecycle.json
```
El archivo `lifecycle.json` es un documento JSON en la carpeta actual que especifica dos reglas:
```
{
"Rules": [
{
"ID": "Move rotated logs to Glacier",
"Prefix": "rotated/",
"Status": "Enabled",
"Transitions": [
{
"Date": "2015-11-10T00:00:00.000Z",
"StorageClass": "GLACIER"
}
]
},
{
"Status": "Enabled",
"Prefix": "",
"NoncurrentVersionTransitions": [
{
"NoncurrentDays": 2,
"StorageClass": "GLACIER"
}
],
"ID": "Move old versions to Glacier"
}
]
}
```
La primera regla mueve los archivos con el prefijo `rotated` a Glacier en la fecha especificada. La segunda regla mueve las versiones del objeto antiguas a Glacier cuando ya no están actualizadas.

#### [ CLI ]
**AWS CLI**
**Ejemplo 1: Configuración del registro de políticas de bucket**
En el siguiente ejemplo de `put-bucket-logging`, se establece la política de registro para *amzn-s3-demo-bucket*. En primer lugar, conceda al servicio de registro el permiso de entidad principal en la política de bucket mediante el comando `put-bucket-policy`.
```
aws s3api put-bucket-policy \
--bucket amzn-s3-demo-bucket \
--policy file://policy.json
```
Contenido de `policy.json`:
```
{
"Version":"2012-10-17",
"Statement": [
{
"Sid": "S3ServerAccessLogsPolicy",
"Effect": "Allow",
"Principal": {"Service": "logging.s3.amazonaws.com"},
"Action": "s3:PutObject",
"Resource": "arn:aws:s3:::amzn-s3-demo-bucket/Logs/*",
"Condition": {
"ArnLike": {"aws:SourceARN": "arn:aws:s3:::SOURCE-BUCKET-NAME"},
"StringEquals": {"aws:SourceAccount": "SOURCE-AWS-ACCOUNT-ID"}
}
}
]
}
```
Para aplicar la política de registro, use `put-bucket-logging`.
```
aws s3api put-bucket-logging \
--bucket amzn-s3-demo-bucket \
--bucket-logging-status file://logging.json
```
Contenido de `logging.json`:
```
{
"LoggingEnabled": {
"TargetBucket": "amzn-s3-demo-bucket",
"TargetPrefix": "Logs/"
}
}
```
El comando `put-bucket-policy` es necesario para conceder permisos `s3:PutObject` a la entidad principal del servicio de registro.
Para obtener más información, consulte [Registro de acceso al servidor de Amazon S3](https://docs.aws.amazon.com/AmazonS3/latest/userguide/ServerLogs.html) en la *Guía del usuario de Amazon S3*.
**Ejemplo 2: Establecimiento de una política de bucket para registrar el acceso a un solo usuario**
En el siguiente ejemplo de `put-bucket-logging`, se establece la política de registro para *amzn-s3-demo-bucket*. El AWS usuario *bob@example.com* tendrá el control total sobre los archivos de registro y nadie más tendrá acceso a ellos. En primer lugar, conceda permiso de S3 mediante `put-bucket-acl`.
```
aws s3api put-bucket-acl \
--bucket amzn-s3-demo-bucket \
--grant-write URI=http://acs.amazonaws.com/groups/s3/LogDelivery \
--grant-read-acp URI=http://acs.amazonaws.com/groups/s3/LogDelivery
```
A continuación, aplique la política de registro mediante `put-bucket-logging`.
```
aws s3api put-bucket-logging \
--bucket amzn-s3-demo-bucket \
--bucket-logging-status file://logging.json
```
Contenido de `logging.json`:
```
{
"LoggingEnabled": {
"TargetBucket": "amzn-s3-demo-bucket",
"TargetPrefix": "amzn-s3-demo-bucket-logs/",
"TargetGrants": [
{
"Grantee": {
"Type": "AmazonCustomerByEmail",
"EmailAddress": "bob@example.com"
},
"Permission": "FULL_CONTROL"
}
]
}
}
```
el comando `put-bucket-acl` es necesario para conceder los permisos necesarios (write y read-acp) al sistema de entrega de registros de S3.
Para obtener más información, consulte [Registro de acceso al servidor de Amazon S3](https://docs.aws.amazon.com/AmazonS3/latest/userguide/ServerLogs.html) en la *Guía para desarrolladores de Amazon S3*.

```
aws s3api put-bucket-notification --bucket amzn-s3-demo-bucket --notification-configuration file://notification.json
```
El archivo `notification.json` es un documento JSON en la carpeta actual que especifica un tema de SNS y un tipo de evento para supervisar:

# Úselo `PutBucketReplication` con un AWS SDK o CLI
Los siguientes ejemplos de código muestran cómo utilizar `PutBucketReplication`.

#### [ CLI ]
**AWS CLI**
**Configurar la replicación de un bucket de S3**
El siguiente ejemplo de `put-bucket-replication` aplica una configuración de replicación al bucket de S3 especificado.
```
aws s3api put-bucket-replication \
--bucket amzn-s3-demo-bucket1 \
--replication-configuration file://replication.json
```
Contenido de `replication.json`:
```
{
"Role": "arn:aws:iam::123456789012:role/s3-replication-role",
"Rules": [
{
"Status": "Enabled",
"Priority": 1,
"DeleteMarkerReplication": { "Status": "Disabled" },
"Filter" : { "Prefix": ""},
"Destination": {
"Bucket": "arn:aws:s3:::amzn-s3-demo-bucket2"
}
}
]
}
```
El bucket de destino debe tener habilitado el control de versiones. El rol especificado debe tener permiso para escribir en el bucket de destino y tener una relación de confianza que permita a Amazon S3 asumir el rol.
Ejemplo de política de permisos de roles:
```
{
"Version":"2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:GetReplicationConfiguration",
"s3:ListBucket"

{
"Effect": "Allow",

"s3:GetObjectVersionAcl",
"s3:GetObjectVersionTagging"
],
"Resource": [
"arn:aws:s3:::amzn-s3-demo-bucket1/*"
]
},
{
"Effect": "Allow",
"Action": [
"s3:ReplicateObject",
"s3:ReplicateDelete",
"s3:ReplicateTags"
],
"Resource": "arn:aws:s3:::amzn-s3-demo-bucket2/*"
}
]
}
```
Ejemplo de política de relación de confianza:
```

# Utilizar `PutBucketRequestPayment` con una CLI
Los siguientes ejemplos de código muestran cómo utilizar `PutBucketRequestPayment`.
------
#### [ CLI ]
**AWS CLI**
**Ejemplo 1: habilitar la configuración de “el solicitante paga” para un bucket**
El siguiente ejemplo de `put-bucket-request-payment` habilita `requester pays` para el bucket especificado.
```
aws s3api put-bucket-request-payment \
--bucket amzn-s3-demo-bucket \
--request-payment-configuration '{"Payer":"Requester"}'
```
Este comando no genera ninguna salida.
**Ejemplo 2: deshabilitar la configuración de “el solicitante paga” para un bucket**
El siguiente ejemplo de `put-bucket-request-payment` deshabilita `requester pays` para el bucket especificado.
```
aws s3api put-bucket-request-payment \
--bucket amzn-s3-demo-bucket \
--request-payment-configuration '{"Payer":"BucketOwner"}'
```
Este comando no genera ninguna salida.

# Utilizar `PutBucketTagging` con una CLI
Los siguientes ejemplos de código muestran cómo utilizar `PutBucketTagging`.
Los ejemplos de acciones son extractos de código de programas más grandes y deben ejecutarse en contexto. Puede ver esta acción en contexto en el siguiente ejemplo de código:
+ [Introducción a S3](s3_example_s3_GettingStarted_section.md)
------
#### [ CLI ]
**AWS CLI**
El siguiente comando aplica una configuración de etiquetado a un bucket denominado `amzn-s3-demo-bucket`:
```
aws s3api put-bucket-tagging --bucket amzn-s3-demo-bucket --tagging file://tagging.json
```
El archivo `tagging.json` es un documento JSON en la carpeta actual que especifica etiquetas:
```
{
"TagSet": [
{
"Key": "organization",
"Value": "marketing"
}
]
}
```
O aplique una configuración de etiquetado a `amzn-s3-demo-bucket` directamente desde la línea de comandos:
```
aws s3api put-bucket-tagging --bucket amzn-s3-demo-bucket --tagging 'TagSet=[{Key=organization,Value=marketing}]'
```
+ Para obtener más información sobre la API, consulte [PutBucketTagging](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/s3api/put-bucket-tagging.html)la *Referencia de AWS CLI comandos*.
------
#### [ PowerShell ]
**Herramientas para la PowerShell versión 4**
**Ejemplo 1: este comando aplica dos etiquetas a un bucket denominado `cloudtrail-test-2018`, una etiqueta con una clave de Stage y un valor de Test, y una etiqueta con una clave de Environment y un valor de Alpha. Para comprobar que las etiquetas se han añadido al bucket, ejecute `Get-S3BucketTagging -BucketName bucket_name`. Los resultados deben mostrar las etiquetas que ha aplicado al bucket en el primer comando. Tenga en cuenta que `Write-S3BucketTagging` sobrescribe todo el conjunto de etiquetas existente en un bucket. Para añadir o eliminar etiquetas individuales, ejecute los cmdlets Resource Groups y Tagging API, `Add-RGTResourceTag` y `Remove-RGTResourceTag`. Como alternativa, puede utilizar el editor de etiquetas de la consola AWS de administración para gestionar las etiquetas de bucket de S3.**
```
Write-S3BucketTagging -BucketName amzn-s3-demo-bucket -TagSet @( @{ Key="Stage"; Value="Test" }, @{ Key="Environment"; Value="Alpha" } )
```
**Ejemplo 2: este comando canaliza un bucket denominado `cloudtrail-test-2018` al cmdlet de `Write-S3BucketTagging`. Aplica las etiquetas Stage:Production y Department:Finance al bucket. Tenga en cuenta que `Write-S3BucketTagging` sobrescribe todo el conjunto de etiquetas existente en un bucket.**
```
