Activity 39: Python Flask Cookie (SIA2)

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

1. Create a New Project Folder:

    mkdir nicolas_python_flask_cookies
    cd nicolas_python_flask_cookies
   

2. Set Up a Virtual Environment:

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

3. 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

1. Run the Flask Application: Execute the following command in your terminal:

    python app.py
   

2. 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"
   

   

3. 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
