httpx-auth-awssigv4

0.1.4 verified Mon Apr 27 auth: no python

A Python library that provides AWS Signature V4 authentication for HTTPX requests. Current version 0.1.4 supports IAM user credentials and STS temporary credentials. Release cadence is low; no recent updates.

pip install httpx-auth-awssigv4

Common errors

error ModuleNotFoundError: No module named 'httpx-auth-awssigv4' ↓

cause Using hyphen instead of underscore in import statement.

fix

Use from httpx_auth_awssigv4 import SigV4Auth.

error TypeError: __init__() missing required positional arguments: 'access_key' and 'secret_key' ↓

cause Credentials not provided to SigV4Auth.

fix

Provide access_key, secret_key (and optionally session_token).

Warnings

gotcha The library requires Python >=3.6.2 but no longer actively maintained; consider using `aws-sigv4` for httpx if updates are needed. ↓

fix Use aws-sigv4 package if newer features required.

gotcha Credentials are passed as parameters; avoid hardcoding. Use environment variables or AWS credential providers. ↓

fix Use os.environ.get() or boto3 session.

gotcha The library does not support automatic credential chain resolution (e.g., from ~/.aws/credentials). You must supply keys explicitly. ↓

fix Provide access_key and secret_key explicitly.

Quickstart

Initialize SigV4Auth with credentials and use it as HTTPX auth.

import os
from httpx import Client
from httpx_auth_awssigv4 import SigV4Auth

auth = SigV4Auth(
    access_key=os.environ.get('AWS_ACCESS_KEY_ID', 'YOUR_ACCESS_KEY'),
    secret_key=os.environ.get('AWS_SECRET_ACCESS_KEY', 'YOUR_SECRET_KEY'),
    region='us-east-1',
    service='execute-api'
)

with Client() as client:
    response = client.get('https://example.amazonaws.com', auth=auth)
    print(response.status_code)
