[FRONTEND] User login logic

[emttiew]

Task Description: Implementing User Login Logic Using REST API with Boost.Beast (Client-Side)

Requirements:

1. HTTP Client Setup:

   • Configure Boost.Beast to act as an HTTP client for making requests to the backend REST API.
   • Set up necessary headers for sending JSON payloads and handling responses.

2. User Authentication Flow:

   • Implement logic to capture user input (username/email and password) from the login interface.
   • Construct JSON payloads containing user credentials to be sent to the backend API endpoint.
   • Handle user interaction events (e.g., button clicks) to initiate the authentication process.

3. HTTP Requests:

   • Use Boost.Beast to send HTTP POST requests to the backend API endpoint for user authentication.
   • Include appropriate error handling mechanisms to deal with network failures or invalid responses.

4. Response Handling:

   • Parse JSON responses received from the backend API to extract authentication status and relevant data.
   • Implement logic to handle different authentication outcomes (e.g., successful login, incorrect credentials, server errors).

5. User Feedback:

   • Provide clear feedback to the user based on the authentication status (e.g., success message, error message).
   • Update the UI dynamically to reflect the outcome of the authentication attempt.

6. Security Considerations:

   • Ensure that sensitive information (e.g., passwords) is transmitted securely over HTTPS.
   • Implement client-side validation to prevent unnecessary requests and enhance security.

7. Testing:

   • Perform unit testing to validate the functionality of the client-side authentication logic.
   • Conduct integration testing to ensure compatibility with the backend REST API.
