Core Code Analysis

1. Server Entry (Form1.frm)

Option Explicit

Private Sub Command1_Click()
    'Launch Layui version
    Shell "explorer.exe http://127.0.0.1:800/layui/easyweb/"
End Sub

Private Sub Command2_Click()
    'Launch Vue2 version
    Shell "explorer.exe http://127.0.0.1:800/vue/eleadmin2/"
End Sub

Private Sub Form_Load()
    'Start Web server
    With HttpServer
        'Register business modules
        .Router.Reg "Users", New bUsers
        .Router.Reg "Menus", New bMenus
        
        'Configure static file directory
        .Start 800, App.Path & "\www"
    End With
End Sub

2. User Management Implementation (bUsers.cls)

'User management business class
Option Explicit

'User list
Public Sub List(ctx As cHttpServerContext)
    With ctx.Response.NewJson
        .Items.Add GetUser(1, "admin", "Administrator")
        .Items.Add GetUser(2, "test", "Test User")
    End With
End Sub

'User login
Public Sub Login(ctx As cHttpServerContext)
    Dim username As String, password As String
    username = ctx.Request.PostData("username")
    password = ctx.Request.PostData("password")
    
    If CheckLogin(username, password) Then
        'Generate token
        With ctx.Response.NewJson
            .Item("code") = 0
            .Item("token") = GenerateToken(username)
            .Item("userInfo") = GetUserInfo(username)
        End With
    Else
        ctx.Response.Error 401, "Invalid username or password"
    End If
End Sub

3. Menu Management Implementation (bMenus.cls)

'Menu management business class
Option Explicit

'Get menu tree
Public Sub GetTree(ctx As cHttpServerContext)
    With ctx.Response.NewJson
        'System management
        With .NewJson("system")
            .Item("title") = "System Management"
            .Item("icon") = "layui-icon-set"
            
            'Add submenus
            With .NewJson("children")
                .Items.Add GetMenuItem("User Management", "/system/user")
                .Items.Add GetMenuItem("Role Management", "/system/role")
                .Items.Add GetMenuItem("Menu Management", "/system/menu")
            End With
        End With
        
        'Business management
        With .NewJson("business")
            .Item("title") = "Business Management"
            .Item("icon") = "layui-icon-app"
            
            With .NewJson("children")
                .Items.Add GetMenuItem("Order Management", "/business/order")
                .Items.Add GetMenuItem("Product Management", "/business/product")
                .Items.Add GetMenuItem("Customer Management", "/business/customer")
            End With
        End With
    End With
End Sub
