API Endpoints for benhall/flask-demo

Documentation: Defined Routes in benhall/flask-demo

Overview

This documentation provides an in-depth overview of the routes defined in the benhall/flask-demo codebase. The routes are primarily structured using Flask blueprints, allowing for modular application design. Below, the routes and their implementation details are discussed along with relevant code snippets.

Routes Defined

Index Route

  • Route: /
  • Method: GET
  • Description: This route serves as the entry point of the application. When accessed, it displays a welcome message.

Implementation Example:

@app.route('/')
def index():
return "Welcome to the Flask demo with Blueprints!"

Test Case Example:

def test_index(self):
response = self.app.get('/')
self.assertEqual(response.status_code, 200)
self.assertIn('Welcome to the Flask demo with Blueprints!', response.data.decode())

Hello Route

  • Route: /hello
  • Method: GET
  • Description: This endpoint responds with a greeting message.

Implementation Example in greetings blueprint:

@greetings.route('/hello')
def hello():
return "Hello there!"

Test Case Example:

def test_hello(self):
response = self.app.get('/hello')
self.assertEqual(response.status_code, 200)
self.assertIn('Hello there!', response.data.decode())

Goodbye Route

  • Route: /goodbye
  • Method: GET
  • Description: This endpoint sends a farewell message.

Implementation Example in greetings blueprint:

@greetings.route('/goodbye')
def goodbye():
return "Goodbye!"

Test Case Example:

def test_goodbye(self):
response = self.app.get('/goodbye')
self.assertEqual(response.status_code, 200)
self.assertIn('Goodbye!', response.data.decode())

Get JSON Route

  • Route: /getjson
  • Method: GET
  • Description: This route returns a JSON object containing a pre-defined set of key-value pairs.

Implementation Example in data blueprint:

@data.route('/getjson')
def get_json():
return jsonify({'key': 'value', 'numbers': [1, 2, 3]})

Test Case Example:

def test_get_json(self):
response = self.app.get('/getjson')
self.assertEqual(response.status_code, 200)
self.assertEqual(response.json, {'key': 'value', 'numbers': [1, 2, 3]})

Post Data Route

  • Route: /postdata
  • Method: POST
  • Description: This route accepts JSON data and returns it back in the response.

Implementation Example:

@data.route('/postdata', methods=['POST'])
def post_data():
data = request.get_json()
return jsonify(data)

Test Case Example:

def test_post_data(self):
response = self.app.post('/postdata',
data=json.dumps({'name': 'Jane', 'age': 28}),
content_type='application/json')
self.assertEqual(response.status_code, 200)
self.assertEqual(response.json, {'name': 'Jane', 'age': 28})

Summary

The routes defined in the benhall/flask-demo codebase leverage Flask’s routing capabilities alongside blueprints for modular design. This setup facilitates clear organization of endpoints, making it straightforward to understand and expand the application’s functionality. The examples provided show both the implementation of the routes and the corresponding test cases, ensuring that the application behaves as expected.
