在使用Abp框架的Web应用程序中，可以动态种子菜单以显示用户有权访问的页面或操作。这可以在Blazor wasm中完成。以下是步骤：

1.在Web应用程序中创建名为AppMenus的类，用于描述菜单项。此类应继承AbpApplicationMenus类型，并在构造函数中添加菜单项。

public class AppMenus : AbpApplicationMenus { public AppMenus(IServiceProvider serviceProvider) : base(serviceProvider) { var adminMenuItem = new ApplicationMenuItem("AbpAdmin", "Admin") { AllowedRoles = new[] { "admin" } }; adminMenuItem.AddItem(new ApplicationMenuItem("AbpAdmin.Home", "Home", "/")); adminMenuItem.AddItem(new ApplicationMenuItem("AbpAdmin.Users", "Users", "/users")); adminMenuItem.AddItem(new ApplicationMenuItem("AbpAdmin.Roles", "Roles", "/roles")); AddItem(adminMenuItem);

    var salesmanMenuItem = new ApplicationMenuItem("AbpSalesman", "Salesman")
    {
        AllowedRoles = new[] { "salesman" }
    };
    salesmanMenuItem.AddItem(new ApplicationMenuItem("AbpSalesman.Home", "Home", "/"));
    salesmanMenuItem.AddItem(new ApplicationMenuItem("AbpSalesman.Customers", "Customers", "/customers"));
    AddItem(salesmanMenuItem);
}

}

2.在Startup.cs文件中添加菜单种子的代码。

services.AddApplication().AddUnitOfWork(); services.AddScoped(); services.AddControllersWithViews() .AddJsonOptions(options => options.JsonSerializerOptions.Converters.Add(new StringEnumConverter()));

services.AddRazorPages();

app.UseStaticFiles();

app.UseRouting();

app.UseAuthentication(); app.UseAbpClaimsMap();

app.UseAuthorization();

app.UseEndpoints(endpoints => { endpoints.MapControllers(); endpoints.MapRazorPages(); endpoints.MapBlazorHub(); endpoints.MapFallbackToPage("/_Host"); });

var serviceProvider = app.ApplicationServices;

var menuBuilder = serviceProvider.GetRequiredService(); menuBuilder.Build(new AppMenus(serviceProvider));

3.在Pages\App.razor文件中，使用标记包装显示菜单的组件以确保只有有权访问的用户才能看到这些菜单。
