security_token	Used for the x-amz-security-token header, for use with STS temporary credentials.	Optional

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)

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:

• OAuth2AuthorizationCodePKCE
• OktaAuthorizationCodePKCE
• OAuth2Implicit
• OktaImplicit
• OktaImplicitIdToken
• AzureActiveDirectoryImplicit
• AzureActiveDirectoryImplicitIdToken
• OAuth2AuthorizationCode
• OktaAuthorizationCode
• OAuth2ClientCredentials
• OktaClientCredentials
• OAuth2ResourceOwnerPasswordCredentials,

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.utcnow() + 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(
        "You are now authenticated on 1234 You may close this tab."
    )
