Gerar uma chave de API do Amazon Bedrock

Para criar uma chave de API Amazon Bedrock de longo prazo, você usa operações de AWS Identity and Access Management API. Primeiro, é necessário atender aos pré-requisitos:

Pré-requisito

Certifique-se de que sua configuração permita que AWS CLI o reconheça automaticamente suas AWS credenciais. Para saber mais, consulte Como definir as configurações da AWS CLI.

Abra um terminal e execute os seguintes comandos:

Execute o seguinte script para criar um usuário do IAM, anexar permissões para realizar ações do Amazon Bedrock e gerar uma chave de API de longo prazo do Amazon Bedrock para associá-la ao usuário:

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)

Abra um terminal e execute o seguinte comando:

pip install aws-bedrock-token-generator

Abra um terminal e execute o seguinte comando:

npm install @aws/bedrock-token-generator

Se você usa o Maven, adicione a seguinte dependência ao pom.xml:

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

Se você usa o Gradle, adicione o seguinte ao seu arquivo 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();
