httpx2-aws-auth 1.0.0

Provides AWS authentication classes to be used with httpx2 authentication parameter

httpx2-aws-auth

Overview

This module provides AWS Signature Version 4 (SigV4) authentication for HTTPX2 (pydantic), supporting both synchronous and asynchronous authentication flows. It includes two main classes:

• AwsSigV4Auth: For direct AWS credential authentication
• AwsSigV4AssumeRoleAuth: For authentication using AWS IAM Role assumption

Features

• Simple integration with HTTPX2 (pydantic)
• Support for both synchronous and asynchronous authentication
• AWS SigV4 signing for API requests
• IAM Role assumption with configurable duration
• Credential expiration and automatic refresh
• Flexible configuration options

Installation

Install the package using pip:

pip install httpx2-aws-auth

Usage

Basic AWS Credentials Authentication

import httpx2
from httpx2_aws_auth import AwsSigV4Auth, AwsCredentials

# Create AWS credentials
credentials = AwsCredentials(
    access_key='YOUR_ACCESS_KEY',
    secret_key='YOUR_SECRET_KEY'
)

# Create an authenticated client
client = httpx2.Client(
    auth=AwsSigV4Auth(
        credentials=credentials,
        region='us-west-2',
        service='execute-api'
    )
)

# Make a request
response = client.get('https://your-api-endpoint.com')

IAM Role Assumption (Synchronous)

import boto3
import httpx2
from httpx2_aws_auth import AwsSigV4AssumeRoleAuth

# Create AWS session
session = boto3.Session()

# Create an authenticated client with role assumption
client = httpx2.Client(
    auth=AwsSigV4AssumeRoleAuth(
        region='us-west-2',
        role_arn='arn:aws:iam::123456789012:role/YourRole',
        session=session,
        duration=timedelta(hours=1)
    )
)

# Make a request
response = client.get('https://your-api-endpoint.com')

IAM Role Assumption (Asynchronous)

import aioboto3
import httpx2
from httpx2_aws_auth import AwsSigV4AssumeRoleAuth

# Create async AWS session
async_session = aioboto3.Session()

# Create an authenticated async client with role assumption
async_client = httpx2.AsyncClient(
    auth=AwsSigV4AssumeRoleAuth(
        region='us-west-2',
        role_arn='arn:aws:iam::123456789012:role/YourRole',
        async_session=async_session,
        duration=timedelta(hours=1)
    )
)

# Make an async request
async with async_client as client:
    response = await client.get('https://your-api-endpoint.com')

Configuration Options

AwsSigV4Auth

• credentials: AWS credentials object
• region: AWS region
• service: AWS service name (default: 'execute-api')

AwsSigV4AssumeRoleAuth

• region: AWS region
• role_arn: IAM Role ARN to assume
• service: AWS service name (default: 'execute-api')
• session: Synchronous boto3 session
• async_session: Asynchronous aioboto3 session
• duration: Credential validity duration (default: 1 hour)
• refresh_buffer: Time before expiration to refresh credentials (default: 0 seconds)

Dependencies

• HTTPX2
• boto3 (for synchronous authentication)
• aioboto3 (for asynchronous authentication)
