Documentation
|
||||
Configuration
|
||||
=============
|
||||
|
||||
Refer to the `documentation on Read the Docs`_.
|
||||
Flask-DigestAuth takes the configuration ``DIGEST_AUTH_REALM`` as the
|
||||
realm. The default realm is ``Login Required``.
|
||||
|
||||
|
||||
Change Log
|
||||
==========
|
||||
Setting the Password
|
||||
====================
|
||||
|
||||
Refer to the `change log`_.
|
||||
The password hash of the HTTP Digest Authentication is composed of the
|
||||
realm, the username, and the password. Example for setting the
|
||||
password:
|
||||
|
||||
::
|
||||
|
||||
from flask_digest_auth import make_password_hash
|
||||
|
||||
user.password = make_password_hash(realm, username, password)
|
||||
|
||||
The username is part of the hash. If the user changes their username,
|
||||
you need to ask their password, to generate and store the new password
|
||||
hash.
|
||||
|
||||
|
||||
Flask-DigestAuth Alone
|
||||
======================
|
||||
|
||||
Flask-DigestAuth can authenticate the users alone.

||||

|
||||
|
||||
In your ``my_app/views.py``:

||||
|
||||
::
|
||||
|

|

||||
|
||||
|

|
||||
Flask-Login Integration
|
||||
=======================
|
||||
|
||||
Flask-DigestAuth works with Flask-Login_. You can write a Flask
|
||||
module that requires log in, without specifying how to log in. The
|
||||
application can use either HTTP Digest Authentication, or the log in
|
||||
forms, as needed.
|
||||
|
||||
To use Flask-Login with Flask-DigestAuth,
|
||||
``login_manager.init_app(app)`` must be called before
|
||||
``auth.init_app(app)``.
|
||||
|
||||
The currently logged-in user can be retrieved at
|
||||
``flask_login.current_user``, if any.
|
||||
|
||||
The views only depend on Flask-Login, but not the Flask-DigestAuth.
|
||||
You can change the actual authentication mechanism without changing
|
||||
the views.
|
||||
|
||||
|
||||

::
|
||||
|

from flask import Flask
|
||||
from flask_digest_auth import DigestAuth
|

from flask_login import LoginManager
|

|
||||
|
||||
In your ``my_app/views.py``:
|
||||
|
||||
::
|
||||
|
||||
import flask_login
|
||||
from flask import Flask, Blueprint, request, redirect
|
||||
from my_app import auth
|
||||
|
||||
bp = Blueprint("admin", __name__, url_prefix="/admin")
|
||||
|
||||
@bp.get("/admin")
|
||||
@flask_login.login_required
|
||||
def admin():
|
||||
return f"Hello, {flask_login.current_user.get_id()}!"
|
||||
|

|

|
||||
|
||||
def init_app(app: Flask) -> None:
|
||||
app.register_blueprint(bp)
|
||||
|
||||
The views only depend on Flask-Login, but not the actual
|
||||
authentication mechanism. You can change the actual authentication
|
||||
mechanism without changing the views.
|
||||
|
||||
|
||||
Session Integration
|
||||
===================
|
||||
|
||||
Flask-DigestAuth features session integration. The user log in
|
||||
is remembered in the session. The authentication information is not
|
||||
requested again. This is different to the practice of the HTTP Digest
|
||||
Authentication, but is convenient for the log in accounting.
|
||||
|
||||
|
||||
Log In Bookkeeping
|
||||
==================
|
||||
|
||||
You can register a callback to run when the user logs in, for ex.,
|
||||
logging the log in event, adding the log in counter, etc.
|
||||
|
||||
::
|
||||
|
||||
@auth.register_on_login
|
||||
def on_login(user: User) -> None:
|
||||
user.visits = user.visits + 1
|
||||
|
||||
|
||||
Log Out
|
||||
=======
|
||||
|
||||
Flask-DigestAuth supports log out. The user will be prompted for the
|
||||
new username and password.
|
||||
|
||||
|
||||
Test Client
|
||||
===========
|
||||
|
||||
Flask-DigestAuth comes with a test client that supports HTTP digest
|
||||
authentication.
|
||||
|
||||
|
||||

||||

||||

def test_admin(self):
|

|
||||
self.assertEqual(response.status_code, 401)
|
||||
response = self.client.get(
|
