To avoid asking for a new token every new request, a token cache is used.

You need to provide the location of your token cache file. It can be a full or relative path (str or pathlib.Path).

If the file already exists it will be used, if the file do not exist it will be created.

from httpx_auth import OAuth2, JsonTokenFileCache

OAuth2.token_cache = JsonTokenFileCache('path/to/my_token_cache.json')

Managing the web browser

You can configure the browser display settings thanks to httpx_auth.OAuth2.display as in the following:

from httpx_auth import OAuth2, DisplaySettings

OAuth2.display = DisplaySettings()

The following parameters can be provided to DisplaySettings:

Name Description Default value

AWS Signature v4

Amazon Web Service Signature version 4 is implemented following Amazon S3 documentation and request-aws4auth 1.2.3 (with some changes, see below).

Use httpx_auth.AWS4Auth to configure this kind of authentication.

import httpx
from httpx_auth import AWS4Auth

aws = AWS4Auth(access_id="my-access-id", secret_key="my-secret-key", region="eu-west-1", service="s3")
with httpx.Client() as client:
    client.get('http://s3-eu-west-1.amazonaws.com', auth=aws)

Note that the following changes were made compared to requests-aws4auth:

Parameters

Name Description Mandatory Default value
access_id AWS access ID. Mandatory  
secret_key AWS secret access key. Mandatory  
region The region you are connecting to, as per this list. For services which do not require a region (e.g. IAM), use us-east-1. Mandatory  
service The name of the service you are connecting to, as per this list. e.g. elasticbeanstalk. Mandatory  
security_token Used for the x-amz-security-token header, for use with STS temporary credentials. Optional  
include_headers Set of headers to include in the canonical and signed headers (in addition to the default). Note that x-amz-client-context is not included by default and * will include all headers. Optional {“host”, “content-type”, “x-amz-*”} and if security_token is provided, x-amz-security-token.

Dynamically retrieving credentials using boto3

While httpx-auth does not want to include support for botocore, the following authentication class should allow you to automatically retrieve up-to-date credentials.

import httpx
from botocore.session import Session
from httpx_auth import AWS4Auth

class AWS4BotoAuth(AWS4Auth):
    def __init__(self, region: str, service: str = "s3", **kwargs):
        self.refreshable_credentials = Session().get_credentials()
        AWS4Auth.__init__(self, access_id=kwargs.pop("access_id", "_"), secret_key=kwargs.pop("secret_key", "_"), region=region, service=service, **kwargs)

    def auth_flow(self, request):
        self.refresh_credentials()
        yield super().auth_flow(request)

    def refresh_credentials(self):
        credentials = self.refreshable_credentials.get_frozen_credentials()
        self.access_id = credentials.access_key
        self.secret_key = credentials.secret_key
        self.security_token = credentials.token


aws = AWS4BotoAuth(region="eu-west-1")
with httpx.Client() as client:
    client.get('http://s3-eu-west-1.amazonaws.com', auth=aws)

API key in header

You can send an API key inside the header of your request using httpx_auth.HeaderApiKey.

import httpx
from httpx_auth import HeaderApiKey

with httpx.Client() as client:
    client.get('https://www.example.com', auth=HeaderApiKey('my_api_key'))

Parameters

Name Description Mandatory Default value
api_key The API key that will be sent. Mandatory  
header_name Name of the header field. Optional “X-API-Key”

API key in query

You can send an API key inside the query parameters of your request using httpx_auth.QueryApiKey.

import httpx
from httpx_auth import QueryApiKey

with httpx.Client() as client:
    client.get('https://www.example.com', auth=QueryApiKey('my_api_key'))

Parameters

Name Description Mandatory Default value
api_key The API key that will be sent. Mandatory  
query_parameter_name Name of the query parameter. Optional “api_key”

Basic

You can use basic authentication using httpx_auth.Basic.

The only advantage of using this class instead of httpx native support of basic authentication, is to be able to use it in multiple authentication.

import httpx
from httpx_auth import Basic

with httpx.Client() as client:
    client.get('https://www.example.com', auth=Basic('username', 'password'))

Parameters

Name Description Mandatory Default value
username User name. Mandatory  
password User password. Mandatory  

Multiple authentication at once

You can also use a combination of authentication using +or & as in the following sample:

import httpx
from httpx_auth import HeaderApiKey, OAuth2Implicit

api_key = HeaderApiKey('my_api_key')
oauth2 = OAuth2Implicit('https://www.example.com')
with httpx.Client() as client:
    client.get('https://www.example.com', auth=api_key + oauth2)

This is supported on every authentication class exposed by httpx_auth, but you can also enable it on your own authentication classes by using httpx_auth.SupportMultiAuth as in the following sample:

from httpx_auth import SupportMultiAuth
# TODO Import your own auth here
from my_package import MyAuth

class MyMultiAuth(MyAuth, SupportMultiAuth):
    pass

Available pytest fixtures

Testing the code using httpx_auth authentication classes can be achieved using provided pytest fixtures.

token_cache_mock

from httpx_auth.testing import token_cache_mock, token_mock

def test_something(token_cache_mock):
    # perform code using authentication
    pass

Use this fixture to mock authentication success for any of the following classes:

By default, an access token with value 2YotnFZFEjr1zCsicMWpAA is generated.

You can however return your custom token by providing your own token_mock fixture as in the following sample:

import pytest

from httpx_auth.testing import token_cache_mock


@pytest.fixture
def token_mock() -> str:
    return "MyCustomTokenValue"


def test_something(token_cache_mock):
    # perform code using authentication
    pass

You can even return a more complex token by using the create_token function.

Note that pyjwt is a required dependency in this case as it is used to generate the token returned by the authentication.

import pytest
from httpx_auth.testing import token_cache_mock, create_token


@pytest.fixture
def token_mock() -> str:
    expiry = None  # TODO Compute your expiry
    return create_token(expiry)


def test_something(token_cache_mock):
    # perform code using authentication
    pass

Advanced testing

token_cache

This pytest fixture will return the token cache and ensure it is reset at the end of the test case.

from httpx_auth.testing import token_cache

def test_something(token_cache):
    # perform code using authentication
    pass

browser_mock

This pytest fixture will allow to mock the behavior of a web browser.

With this pytest fixture you will be allowed to fine tune your authentication related failures handling.

pyjwt is a required dependency if you use create_token helper function.

import datetime

from httpx_auth.testing import browser_mock, BrowserMock, create_token

def test_something(browser_mock: BrowserMock):
    token_expiry = datetime.datetime.now(datetime.timezone.utc) + datetime.timedelta(hours=1)
    token = create_token(token_expiry)
    tab = browser_mock.add_response(
        opened_url="http://url_opened_by_browser?state=1234",
        reply_url=f"http://localhost:5000#access_token={token}&state=1234",
    )

    # perform code using authentication

    tab.assert_success()
