使用 Razor 页面更改 ASP.Net Core 2.1 中的主页

Question

我正在使用 Razor 页面开发 ASP.Net Core 2.1 网站，这是我第一次使用 Razor 页面。但我想做的是更改主页或登录页面。因此，如果用户未登录，该站点应重定向到 Areas 文件夹中的 /Account/Login 页面，但如果用户已登录，则应转到页面文件夹中名为 DataManagement 的页面，如下所示。

我已经缝制了身份，并且在配置服务中尝试了类似下面的操作：

services.AddMvc().AddRazorPagesOptions(options =>
{
    options.Conventions.AddAreaPageRoute("Identity", "/Account/Login", "");
}).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

并且在配置方法中：

app.UseMvc(routes =>
{
    routes.MapRoute(
        name: "default",
        template: "{controller=Home}/{action=Index}/{id?}");
});

无果。

编辑我的 StartUp.cs

public class 启动 { public Startup(IConfiguration配置) { 配置=配置； }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });

        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(
                Configuration.GetConnectionString("Connection")));
        services.AddIdentity<ApplicationUser, ApplicationRole>(
            options => options.Stores.MaxLengthForKeys = 128)
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultUI()
            .AddDefaultTokenProviders()
            .AddEntityFrameworkStores<ApplicationDbContext>();


        services.AddMvc().AddRazorPagesOptions(opts =>
        {
            opts.Conventions.AddPageRoute("/DataManagement", "/");
            opts.Conventions.AddPageRoute("/DataManagement", "home");
            opts.Conventions.AddPageRoute("/DataManagement", "index");

        }).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);


    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ApplicationDbContext context, RoleManager<ApplicationRole> roleManager, UserManager<ApplicationUser> userManager, IServiceProvider serviceProvider)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseDatabaseErrorPage();
        }
        else
        {
            app.UseExceptionHandler("/Error");
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseCookiePolicy();

        app.UseAuthentication();

        app.UseMvc();

    }

最简单的方法就是在 DataManagement.cshtml.cs 文件中使用 [Authorize] 属性。

[Authorize]
public class DataManagementModel : PageModel
{
    public void OnGet()
    {

    }
}

只需像往常一样在 Startup.cs 中配置您的默认主页：

services.AddMvc().AddRazorPagesOptions(opts =>
{
    opts.Conventions.AddPageRoute("/DataManagement", "/");
    opts.Conventions.AddPageRoute("/DataManagement", "home");
    opts.Conventions.AddPageRoute("/DataManagement", "index");
    opts.Conventions.AddAreaPageRoute("Account", "/Login", "/Account/Login");

}).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

services.ConfigureApplicationCookie(options =>
{
    options.LoginPath = $"/Account/Login";
});

并在配置中：

        app.UseMvc(routes =>
        {
            routes.MapRoute(
               name: "default",
               template: "{controller=Home}/{action=Index}/{id?}");

        });

然后删除 Index.cshtml

我认为在这种情况下你需要像上面那样定义自定义登录，取自here
