Login with HTTP in Qt C++ (Client-Side) | Media Player Project Tutorial – Part 2a

Part 2a – Qt + C++ Media Player: Login (Client-Side)
Welcome back to the Ultimate Qt + C++ Media Player Tutorial Series!
In this part, we’re diving into the Login system — but from the backend (client) side. We’ll send login credentials (email + password) from Qt to our dummy FastAPI server using QNetworkAccessManager( https://doc.qt.io/qt-6/qnetworkaccess... ), all while handling async responses.

The dummy python server used in the tutorial is here ====)

What You'll Learn in This Part:

🔹 Sending POST requests from Qt C++ to a backend
🔹 Using QNetworkAccessManager and QNetworkReply properly
🔹 Building a clean, reusable login backend logic for your UI
🔹 Managing loading states using Q_PROPERTY and signals

This is Part 2a — just the start of the authentication flow. In Part 2b, we’ll handle token-based authentication and fetch the user profile to complete a real login system.
