Generare una chiave API Amazon Bedrock

Per creare una chiave API Amazon Bedrock a lungo termine, utilizzi le operazioni AWS Identity and Access Management API. Verifica innanzitutto di soddisfare il prerequisito:

Prerequisito

Assicurati che la configurazione consenta loro di AWS CLI riconoscere automaticamente le tue AWS credenziali. Per ulteriori informazioni, consulta Configurazione delle impostazioni per la AWS CLI.

Esegui lo script seguente per creare un utente IAM, collegare le autorizzazioni per eseguire azioni Amazon Bedrock e generare una chiave API Amazon Bedrock a lungo termine da associare all’utente:

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)

Apri un terminale ed esegui questo comando:

pip install aws-bedrock-token-generator

Apri un terminale ed esegui questo comando:

npm install @aws/bedrock-token-generator

Se utilizzi Maven, aggiungi la dipendenza seguente a pom.xml:

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

Se usi Gradle, aggiungi quanto segue a build.gradle:

implementation 'software.amazon.bedrock:aws-bedrock-token-generator:1.1.0'

from aws_bedrock_token_generator import provide_token

token = provide_token()
print(f"Token: {token}")

import { getTokenProvider } from "@aws/bedrock-token-generator";

// Create a token provider that uses default credentials and region providers.
// You can configure it to use other credential providers.
const provideToken = getTokenProvider();

async function example() {
    
  const token = await provideToken();

  // 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 
  // token validity period will always be the minimum of the requested expiration 
  // time and the AWS credentials' expiry time
  console.log(`Bearer Token: ${token}`);
}

import software.amazon.bedrock.token.BedrockTokenGenerator;

// Credentials and region will be picked up from the default provider chain
BedrockTokenGenerator tokenGenerator = BedrockTokenGenerator.builder().build();
tokenGenerator.getToken();
