Use AWS SigV4 authorization with requests.

Accessing an API secured with IAM authorization in AWS API Gateway can be tricky.

This tool uses the built-in authorization strategy in `requests` to help you access your secured endpoints.

## Installation

```bash

pip install requests-iamauth

```

## Usage

### Signing Version 4

AWS [sigv4](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html) is the current standard for signing requests bound for AWS services.

Use `requests-iamauth` to as an authorizer for the `requests` Python library:

```python

import requests

from iamauth import Sigv4Auth

sigv4 = Sigv4Auth(

  service_name="execute-api",  # default

)

session = requests.Session()

session.auth = sigv4

session.get('https://abcdef0123.execute-api.us-east-2.amazonaws.com/my/api')

```

Override the default boto3 session by passing a custom one into the constructor for `Sigv4Auth`:

```python

import boto3

sigv4 = Sigv4Auth(

  boto3_session=boto3.Session(),

)

```

### Signing Version 4a

AWS [sigv4a](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html) is an extension to the sigv4 signing process that enables signing requests bound for more than one region.

> Note — at the time of this writing, the only API Gateway API type that appears to support the new sigv4a are REST APIs.

Use `requests-iamauth` to as an authorizer for the `requests` Python library:

```python

import requests

from iamauth import Sigv4aAuth

sigv4a = Sigv4aAuth(

  service="execute-api",  # default

  region="*",             # default

)

session = requests.Session()

session.auth = sigv4a

session.get('https://abcdef0123.execute-api.us-east-2.amazonaws.com/my/api')

```

Override the default AWS credentials provider by passing a custom one into the constructor for `Sigv4aAuth`:

```python

from botocore.compat import awscrt

sigv4a = Sigv4aAuth(

  credentials_provider=awscrt.auth.AwsCredentialsProvider.new_default_chain(),

)

```
