Activity 39: Python Flask Cookie

Implementation of a Flask application that handles cookies using both POST and GET methods as per the Activity 39 requirements.

Implementing Cookies in Flask

Step 1: Set Up Your Flask Project

Create a New Project Folder:

  mkdir nicolas_python_flask_cookies
  cd nicolas_python_flask_cookies

Set Up a Virtual Environment:

  python -m venv venv
  venv\Scripts\activate  # For Windows users
  pip install Flask

Create the Main Application File: Create a file named app.py and add the following code:

  from flask import Flask, request, make_response, jsonify

  app = Flask(__name__)

  @app.route('/setcookies', methods=['POST'])
  def set_cookies():
      # Get the cookie value from the POST request
      cookie_value = request.form.get('cookie_value')
      response = make_response(jsonify({"message": "Cookie has been set!"}))
      # Set the cookie
      response.set_cookie('my_cookie', cookie_value)
      return response

  @app.route('/getcookies', methods=['GET'])
  def get_cookies():
      # Retrieve the cookie from the request
      cookie_value = request.cookies.get('my_cookie')
      if cookie_value:
          return jsonify({"cookie_value": cookie_value})
      return jsonify({"message": "No cookie found!"})

  if __name__ == '__main__':
      app.run(debug=True)

Step 2: Test Your Application

Run the Flask Application: Execute the following command in your terminal:
```
  python app.py
```

Setting the Cookie: You can use a tool like Postman.

Set method to POST

  http://127.0.0.1:5000/setcookies -d "cookie_value=your_cookie_value_here"

Getting the Cookie: To retrieve the cookie, send a GET request:
```
  http://127.0.0.1:5000/getcookies
```

Step 3: Initialize Git and Push to GitHub

git init
git add .
git commit -m "Initial commit for Python Flask cookie implementation"
git remote add origin https://github.com/MonetForProgrammingPurposes/nicolas_python_flask_cookies.git
git branch -M master
git push -u origin master
