How to Integrate

Opening the Login Window

// Load and display the login page of Casdoor

Listening to the Open Application Event

// Initialize the TcpServer object and listen on port 8080
m_tcpserver = new QTcpServer(this);
if (!m_tcpserver->listen(QHostAddress::LocalHost, 8080)) {
qDebug() << m_tcpserver->errorString();
connect(m_tcpserver, SIGNAL(newConnection()), this, SLOT(on_tcp_connected()));

Using Auth Code to Get the User Info

// Get the token and parse it with the JWT library
std::string token = m_casdoor->GetOAuthToken(code.toStdString());
auto decoded = m_casdoor->ParseJwtToken(token);
