Authenticating with GitLab Credentials in Karate Store

The Karate Store is a basic e-commerce application developed using the Qt 6.0 framework. In this article, we'll explore how to implement an authenticator login process that uses GitLab credentials.

GitLab allows users to register and log in with their email address and password. However, for an even more secure authentication mechanism, we can use the Authenticator API provided by GitLab.

Authenticating using GitLab Authenticator API

The Authenticator API provides a simple way to authenticate users without storing passwords. Here's how it works:

• When a user logs in, the server sends an authenticator token with their username and password.
• The client (Karate Store) receives this token and includes it in the next request.
• The server then verifies the authenticity of the token by checking the GitLab Authenticator API.

Here's a simple example of how to implement the authenticator login process using Python and the Qt 6.0 framework:

        import QtWebEngineWidgets
        from PyQt5.QtCore import QUrl, QString

        class AuthenticatorLogin(QWidget):
            def __init__(self):
                super().__init__()

                self.windowState = None
                self.authToken = ""

            def login(self, username, password):
                # Send a request to the GitLab Authenticator API with the username and password
                url = "https://gitlab.com/oauth/v4/token"
                headers = {
                    'Content-Type': 'application/x-www-form-urlencoded',
                    'Accept': 'application/json'
                }
                data = {
                    'grant_type': 'password',
                    'username': username,
                    'password': password,
                    'client_id': "your_client_id",
                    'redirect_uri': "https://gitlab.com"
                }

                response = requests.post(url, headers=headers, data=data)
                if response.status_code == 200:
                    self.authToken = response.json()['access_token']
                    return True
                else:
                    return False

        def authenticate(self):
            # Get the username and password from the user
            username = "your_username"
            password = "your_password"

            # Login to the GitLab server using the AuthenticatorLogin class
            login_window = AuthenticatorLogin()
            if login_window.login(username, password):
                print("Login successful!")
            else:
                print("Invalid credentials")

        def showWindow(self):
            self.resize(300, 200)
            self.setWindowTitle("Karate Store Authenticated")
            self.show()

    # Create an instance of the AuthenticatorLogin class
    login_window = AuthenticatorLogin()
    login_window.showWindow()
