Setting Up the Routes

For this section, we'll need to add three routes to:

• Display the login page,
• Process the login request, and
• Process the logout request.

We'll add these new routes to the previously created userRoutes group in routes.go as follows:

// routes.go

    userRoutes := router.Group("/u")
    {
        // . (existing content, not shown)
        // .
        userRoutes.GET("/login", showLoginPage)
        userRoutes.POST("/login", performLogin)
        userRoutes.GET("/logout", logout)
    }
