BedrockTokenGenerator

✓ from aws_bedrock_token_generator import BedrockTokenGenerator

✗ from aws_bedrock_token_generator import get_bearer_token

✗ from aws_bedrock_token_generator import get_bearer_token

token_generator

✓ from aws_bedrock_token_generator import token_generator

✗ from aws_bedrock_token_generator import get_bearer_token

Generate a bearer token using default AWS credentials (from environment or ~/.aws/credentials).

from aws_bedrock_token_generator import get_bearer_token import os # AWS credentials must be configured (via env vars or boto3 session) token = get_bearer_token() # token is a dict: {'access_token': '...', 'expires_in': 3600} print(token['access_token'])

Debug

Known issues

gotchaThe token expires quickly (default 1 hour). Do not cache tokens without respecting the expiry. Re-generate for each session or use the BedrockTokenGenerator class with caching built-in.

fix

Use BedrockTokenGenerator class or implement your own caching with token expiry check.

affects: <=1.1.0

deprecatedThe low-level `get_bearer_token` function is deprecated in favor of the `BedrockTokenGenerator` class which provides better caching and refresh logic.

fix

Use `from aws_bedrock_token_generator import BedrockTokenGenerator` and instantiate `generator = BedrockTokenGenerator()` then call `generator.get_token()`.

affects: >=1.0.0

gotchaThe library requires boto3 and AWS credentials. If credentials are missing, it raises a `CredentialsError` (from boto3).

fix

Ensure AWS credentials are set via environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY) or a default profile.

affects: all
