# Flask JWT Router
Flask JWT Router is a Python library that adds authorised routes to a Flask app. Both basic & Google's OAuth2.0 authentication
is supported.
##  Google's OAuth2.0 supported
## Quik Start
```python
from flask_jwt_router import JwtRoutes
jwt_routes = JwtRoutes()
jwt_routes.init_app(
app,
entity_models=[MyModel],
)
```
Now your front end needs a token. Create an endpoint &
return a new access token from the clients header *code*.
For Example::
```python
from flask import request
@app.routes("/login", methods=["POST"])
def login():
jwt_routes.google.oauth_login(request) # Pass in Flask's request
```
Now, the next time your front-end requests authorised resources
flask-jwt-router will authenticate with this access token until
it expires.
## Installation
Stable version
```bash
pip install flask-jwt-router
```
## Basic Usage
```python
from flask import Flask
from flask_jwt_router import JwtRoutes
app = Flask(__name__)
# You are required to always set a unique SECRET_KEY for your app
app.config["SECRET_KEY"] = "your_app_secret_key"
JwtRoutes(app)
# If you're using the Flask factory pattern:
jwt_routes = JwtRoutes() # Example with *entity_model - see below
def create_app(config):
...
jwt_routes.init_app(app)
```
## Whitelist Routes
```python
app.config["WHITE_LIST_ROUTES"] = [
("POST", "/register"),
]
@app.route("/register", methods=["POST"])
def register():
return "I don't need authorizing!"
```
## Prefix your api name to whitelisted routes
```python
# All routes will
app.config["JWT_ROUTER_API_NAME"] = "/api/v1"
app.config["WHITE_LIST_ROUTES"] = [
("POST", "/register"),
]
@app.route("/api/v1/register", methods=["POST"])
def register():
return "I don't need authorizing!"
```
## Bypass Flask-JWT-Router on specified routes
```python
# Define homepage template routes for example on JWT_IGNORE_ROUTES
# & still get to use the api name on request handlers returning resources
app.config["IGNORED_ROUTES"] = [
("GET", "/")
]
```
## Declare an entity model
```python
# Create your entity model (example uses Flask-SqlAlchemy)
class UserModel(db.Model):
__tablename__ = "users"
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String)
# You can define the primary key name with `ENTITY_KEY` on Flask's config
app.config["ENTITY_KEY"] = "user_id"
# (`id` is used by default)
JwtRoutes(app, entity_models=[UserModel, TeacherModel, ...etc])
# Or pass later with `init_app`
def create_app(config):
...
jwt_routes.init_app(app, entity_models=[UserModel, TeacherModel, ...etc])
```
## Authorization
```python
from your_app import jwt_routes
# white list the routes
app.config["WHITE_LIST_ROUTES"] = [
("POST", "/register"),
("POST", "/login"),
]
@app.route("/login", methods=["POST"])
def register():
"""I'm registering a new user & returning a token!"""
return jsonify({
"token": jwt_routes.create_token(entity_id=1, table_name='users')
})
@app.route("/your_resource", methods=["POST"])
def login():
"""I'm authorized & updating my token!"""
return jsonify({
"token": jwt_routes.update_token(entity_id=1)
})
```
*Warning: The `table_name` must be the same as your tablename or `__tablename__` attribute's value.
(With SqlAlchemy, you can define a `__tablename__` attribute directly or else
the name is derived from your entity’s database table name).
## Setting the Token Expire Duration
There are two ways to set the expire duration of the JWT.
from your app config
```python
# Set the token expire duration to 7 days
app.config["JWT_EXPIRE_DAYS"] = 7
```
calling the `set_exp`
```python
# Set the token expire duration to 14 days
jwt_routes = JwtRoutes()
# jwt_routes.init_app( ...etc
jwt_routes.set_exp(expire_days=14)
```
By default the expire duration is set to 30 days
## Create & update Tokens on Routes
Create a new entity & return a new token
```python
@app.route("/register", methods=["POST"])
def register():
user_data = request.get_json()
try:
user = UserModel(**user_data)
user.create_user() # your entity creation logic
# Here we pass the id as a kwarg to `create_token`
token: str = jwt_routes.create_token(entity_id=user.id, table_name="users")
# Now we can return a new token!
return {
"message": "User successfully created.",
"token": str(token), # casting is optional
}, 200
```
Access entity on Flask's global context
```python
from app import app, jwt_routes
# Example uses Marshmallow to serialize entity object
class EntitySchema(Schema):
id = fields.Integer()
name = fields.String()
@app.route("/login", methods=["GET"])
def login():
user_data = g.get("users") # This is your SqlAlchemy `__tablename__` or the default name.
try:
user_dumped = UserSchema().dump(user_data)
except ValidationError as _:
return {
"error": "User requested does not exist."
}, 401
return {
"data": user_dumped,
"token": jwt_routes.update_token(entity_id=user_data.id),
}, 200
```
If you are handling a request with a token in the headers you can call::
```python
jwt_routes.update_token(entity_id=user_data.id)
```
If you are handling a request without a token in the headers you can call::
```python
jwt_routes.create_token(entity_id=user_data.id, table_name="users")
```
An Example configuration for registering & logging in users of different types:
```python
app.config["IGNORED_ROUTES"] = [("GET", "/")]
app.config["JWT_ROUTER_API_NAME"] = "/api/v1"
app.config["WHITE_LIST_ROUTES"] = [
("POST", "/auth/user"), ("POST", "/auth/user/login"),
("POST", "/auth/teacher"), ("POST", "/auth/teacher/login"),
]
# Optionally, you can pass your models to Flask's config:
app.config["ENTITY_MODELS"] = [ UserModel, TeacherModel, ...etc ]
```
## JSON Web Token setup
To send the JSON web token from your front end, you will need to pass a `Bearer` string in your authorization header.
For example:
```javascript
fetch(url, {
headers: {
Authorization: "Bearer <my_token>",
}
})
```
### Routing without headers
If you require calling a resource without passing headers, then you can use the ``auth`` query param (useful when streaming video files):
```python
url = "http://example.com/cars?auth=my_token"
```
### Google OAuth 2.0 Quick Start
Read the detailed instructions here: [Flask-JWT-Router](https://flask-jwt-router.readthedocs.io/en/latest/google.html)
```python
from flask_jwt_router import Google, JwtRoutes
oauth_options = {
"client_id": "<CLIENT_ID>",
"client_secret": "<CLIENT_SECRET>",
"redirect_uri": "http://localhost:3000",
"tablename": "users",
"email_field": "email",
"expires_in": 3600,
}
jwt_routes = JwtRoutes()
jwt_routes.init_app(
app,
google_oauth=oauth_options,
strategies=[Google],
entity_models=[MyModel],
)
```
## Google OAuth 2.0 with ReactJS
Flask-JWT-Router supports auth Google's OAuth 2.0 Single Sign On strategy if you are using React only.
(We will provide Google's OAuth 2.0 Single Sign On strategy for server to server as soon as possible!).
### Quick Start
Create a login route for Google's OAuth 2.0
```python
@app.route("/api/v1/google_login", methods=["POST"])
def google_login():
google = jwt_routes.get_strategy("Google")
data = google.oauth_login(request)
return data, 200
```
If your app requires multiple redirect uri's then
you can use the `redirect_uri` kwarg to assign a uri for the current
request handler. For example:
```python
google = jwt_routes.get_strategy("Google")
data = google.oauth_login(request, redirect="http://another_redirect.com")
```
We have created a ReactJS library specifically for Flask-JWT-Router - [react-google-oauth2.0](https://github.com/joegasewicz/react-google-oauth2.0)
In your React app directory install react-google-oauth2.0:
```bash
npm install react-google-oauth2 --save
```
## Testing
Testing OAuth2.0 in a Flask app is non-trivial, especially if you rely on Flask-JWT-Router
to append your user onto Flask's global context (or `g`). Therefore we have provided a
utility method that returns a headers Dict that you can then use in your test view handler
request. This example is using the Pytest library:
```python
from flask_jwt_router import (
BaseJwtRoutes,
JwtRoutes,
Google,
GoogleTestUtil,
TestRoutingMixin,
)
class TestJwtRoutes(TestRoutingMixin, BaseJwtRoutes):
pass
if not Config.E2E_TEST:
jwt_routes = JwtRoutes()
else:
jwt_routes = TestJwtRoutes()
if not config.E2E_TEST:
jwt_routes.init_app(
app,
google_oauth=oauth_options,
strategies=[Google],
entity_models=[MyModel],
)
else:
jwt_routes.init_app(
app,
google_oauth=oauth_options,
strategies=[GoogleTestUtil],
entity_models=[MyModel],
)
```
```python
@pytest.fixture()
def client():
# See https://flask.palletsprojects.com/en/1.1.x/testing/ for details
def test_blogs(client):
google = jwt_routes.get_strategy("GoogleTestUtil")
user_headers = google.create_test_headers(email="user@gmail.com")
rv = client.get("/blogs", headers=user_headers)
```
If you are not running a db in your tests, then you can use the `entity` kwarg.
For example:
```python
# user is an instantiated SqlAlchemy object
google = jwt_routes.get_strategy("GoogleTestUtil")
user_headers = google.create_test_headers(email="user@gmail.com", entity=user)
# user_headers: { "X-Auth-Token": "Bearer <GOOGLE_OAUTH2_TEST>" }
```
If you require more than one request to a Flask view handler in a single unit test, then set
the *scope* kwarg to **application**. (Default is *function*). If you are testing different
entities within a single unit test method or function then you must pass in your entity.
For example:
```python
my_entity = User(email="user@gmail.com") # If you're testing against a real db, make sure this is an entry in the db
google = jwt_routes.get_strategy("GoogleTestUtil")
_ = google.create_test_headers(email="user@gmail.com", scope="application", entity=my_entity)
```
