Installation

Usage Examples

Using requests

from aws_http_auth.credentials import AWSCredentials
from aws_http_auth.http_auth import AWSV4SignerAuth
import requests

creds = AWSCredentials.from_ini_file("~/.aws/credentials")
auth = AWSV4SignerAuth(credentials=creds)

session = requests.Session()
session.auth = auth

response = session.request(
    method="POST",
    url="https://secretsmanager.us-east-1.amazonaws.com/",
    json={
        "SecretId": "MyTestDatabaseSecret",
    },
    headers={
        "Content-Type": "application/x-amz-json-1.1",
        "X-Amz-Target": "secretsmanager.GetSecretValue",
    },
)

Using httpx

from aws_http_auth.credentials import AWSCredentials
from aws_http_auth.http_auth import AWSV4SignerAuth
import httpx

creds = AWSCredentials.from_ini_file()
auth = AWSV4SignerAuth(credentials=creds)

async with httpx.AsyncClient(auth=auth) as client:
    response = await client.post(
        "https://secretsmanager.us-east-1.amazonaws.com/",
        json={
            "SecretId": "MyTestDatabaseSecret",
        },
        headers={
            "Content-Type": "application/x-amz-json-1.1",
            "X-Amz-Target": "secretsmanager.GetSecretValue",
        },
    )

Profile Selection

• If no profile is specified, the library uses the AWS_PROFILE environment variable
• If only one profile exists in the credentials file, it's used automatically
• If multiple profiles exist and none is specified, an error is raised
