### Managing token cache
To avoid asking for a new token every new request, a token cache is used.
Default cache is in memory but it is also possible to use a physical cache.
You need to provide the location of your token cache file. It can be a full or relative path.
If the file already exists it will be used, if the file do not exists it will be created.
```python
from httpx_auth import OAuth2, JsonTokenFileCache
OAuth2.token_cache = JsonTokenFileCache('path/to/my_token_cache.json')
```
## AWS Signature v4
Amazon Web Service Signature version 4 is implemented following [Amazon S3 documentation](https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-auth-using-authorization-header.html) and [request-aws4auth](https://github.com/sam-washington/requests-aws4auth).
Use `httpx_auth.AWS4Auth` to configure this kind of authentication.
```python
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)
```
### 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](http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region). 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](http://docs.aws.amazon.com/general/latest/gr/rande.html). e.g. elasticbeanstalk. | Mandatory | |
| `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`.
```python
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`.
```python
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](#multiple-authentication-at-once).
```python
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:
```python
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`][6] fixtures.
### token_cache_mock
```python
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:
```python
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`](https://pypi.org/project/PyJWT/) is a required dependency in this case as it is used to generate the token returned by the authentication.
```python
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`][6] fixture will return the token cache and ensure it is reset at the end of the test case.
```python
from httpx_auth.testing import token_cache
def test_something(token_cache):
# perform code using authentication
pass
```
#### browser_mock
This [`pytest`][6] fixture will allow to mock the behavior of a web browser.
With this [`pytest`][6] fixture you will be allowed to fine tune your authentication related failures handling.
[`pyjwt`](https://pypi.org/project/PyJWT/) is a required dependency if you use `create_token` helper function.
```python
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."
)

### Managing token cache
To avoid asking for a new token every new request, a token cache is used.
Default cache is in memory but it is also possible to use a physical cache.
You need to provide the location of your token cache file. It can be a full or relative path.
If the file already exists it will be used, if the file do not exists it will be created.
```python
from httpx_auth import OAuth2, JsonTokenFileCache
OAuth2.token_cache = JsonTokenFileCache('path/to/my_token_cache.json')
```
## AWS Signature v4
Amazon Web Service Signature version 4 is implemented following [Amazon S3 documentation](https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-auth-using-authorization-header.html) and [request-aws4auth](https://github.com/sam-washington/requests-aws4auth).
Use `httpx_auth.AWS4Auth` to configure this kind of authentication.
```python
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)
```
### 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](http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region). 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](http://docs.aws.amazon.com/general/latest/gr/rande.html). e.g. elasticbeanstalk. | Mandatory | |
| `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`.
```python
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`.
```python
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](#multiple-authentication-at-once).
```python
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:
```python
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`][6] fixtures.
### token_cache_mock
```python
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:
```python
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`](https://pypi.org/project/PyJWT/) is a required dependency in this case as it is used to generate the token returned by the authentication.
```python
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`][6] fixture will return the token cache and ensure it is reset at the end of the test case.
```python
from httpx_auth.testing import token_cache
def test_something(token_cache):
# perform code using authentication
pass
```
#### browser_mock
This [`pytest`][6] fixture will allow to mock the behavior of a web browser.
With this [`pytest`][6] fixture you will be allowed to fine tune your authentication related failures handling.
[`pyjwt`](https://pypi.org/project/PyJWT/) is a required dependency if you use `create_token` helper function.
```python
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."
)
```

| Name | Description |
|:----------------|:---------------------------------------------------------------------|
| `prompt` | none to avoid prompting the user if a session is already opened. |
### Managing token cache
To avoid asking for a new token every new request, a token cache is used.
Default cache is in memory but it is also possible to use a physical cache.
You need to provide the location of your token cache file. It can be a full or relative path.
If the file already exists it will be used, if the file do not exists it will be created.
```python
from httpx_auth import OAuth2, JsonTokenFileCache
OAuth2.token_cache = JsonTokenFileCache('path/to/my_token_cache.json')
```
## AWS Signature v4
Amazon Web Service Signature version 4 is implemented following [Amazon S3 documentation](https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-auth-using-authorization-header.html) and [request-aws4auth](https://github.com/sam-washington/requests-aws4auth).
Use `httpx_auth.AWS4Auth` to configure this kind of authentication.
```python
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)
```
### 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](http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region). 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](http://docs.aws.amazon.com/general/latest/gr/rande.html). e.g. elasticbeanstalk. | Mandatory | |
| `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`.
```python
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`.
```python
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](#multiple-authentication-at-once).
```python
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:
```python
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`][6] fixtures.
### token_cache_mock
```python
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:
```python
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`](https://pypi.org/project/PyJWT/) is a required dependency in this case as it is used to generate the token returned by the authentication.
```python
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`][6] fixture will return the token cache and ensure it is reset at the end of the test case.
```python
from httpx_auth.testing import token_cache
def test_something(token_cache):
# perform code using authentication
pass
```
#### browser_mock
This [`pytest`][6] fixture will allow to mock the behavior of a web browser.
With this [`pytest`][6] fixture you will be allowed to fine tune your authentication related failures handling.
[`pyjwt`](https://pypi.org/project/PyJWT/) is a required dependency if you use `create_token` helper function.
```python
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."
)
