Génération d’une clé d’API Amazon Bedrock

Pour créer une clé d’API Amazon Bedrock à long terme, vous devez utiliser les opérations d’API Gestion des identités et des accès AWS. Tout d’abord, vérifiez que vous remplissez les conditions requises :

Conditions préalables

Assurez-vous que votre configuration permet à l’AWS CLI de reconnaître automatiquement vos informations d’identification AWS. Pour en savoir plus, consultez Configuration des paramètres pour l’AWS CLI.

Ouvrez une fenêtre de terminal et exécutez les commandes suivantes :

Assurez-vous que votre configuration permet à Python de reconnaître automatiquement vos informations d’identification AWS. Pour en savoir plus, consultez Configuration des paramètres pour l’AWS CLI.

Exécutez le script suivant pour créer un utilisateur IAM, associer des autorisations pour effectuer des actions Amazon Bedrock et générer une clé d’API Amazon Bedrock à long terme à associer à l’utilisateur :

import boto3
from datetime import datetime, timedelta

# Replace with name for your IAM user
username = "bedrock-api-user"
# Add any AWS-managed or custom policies that you want to the user
bedrock_policies = [
    "arn:aws:iam::aws:policy/AmazonBedrockLimitedAccess",        # Limited access
#    "arn:aws:iam::aws:policy/AmazonBedrockMarketplaceAccess",   # Optional: Access to Amazon Bedrock Marketplace actions
]
# Set the key expiration time to a number of your choice
expiration_time_in_days = 30

iam_client = boto3.client("iam")
    
# Create IAM user
user = iam_client.create_iam_user(username)

# Attach policies to user
for policy_arn in bedrock_policies:
    iam_client.attach_managed_policy(username, policy_arn)

# Create long-term Amazon Bedrock API key and return it
service_credentials = iam_client.create_service_specific_credential(
    user_name=username, 
    service_name="bedrock",
    credential_age_days=expiration_time_in_days
) 
api_key = service_credentials["ServiceApiKeyValue"]
print(api_key)

Ouvrez un terminal et exécutez la commande suivante :

pip install aws-bedrock-token-generator

Si vous utilisez Maven, ajoutez la dépendance suivante à votre fichier pom.xml :

<dependency>
    <groupId>software.amazon.bedrock</groupId>
    <artifactId>aws-bedrock-token-generator</artifactId>
    <version>1.1.0</version>

Si vous utilisez Gradle, ajoutez ce qui suit à votre build.gradle :

// You can configure it to use other credential providers.
const provideToken = getTokenProvider();

async function example() {

  // Use the token for API calls. The token has a default expiration of 12 hour.
  // If the expiresInSeconds parameter is specified during token creation, the 
  // expiration can be configured up to a maximum of 12 hours. However, the actual

  console.log(`Bearer Token: ${token}`);
