ASP.NET Core 3.1区域在某些方法上返回404，但不在索引1上返回404 [英] ASP.NET Core 3.1 areas return 404 on some methods but not on the Index one

问题描述

我有以下简单的解决方案，其中一个区域名为Test:

在我的Startup.cs中:

 公共类启动{公共启动(IConfiguration配置){配置=配置；}公共IConfiguration配置{}//此方法由运行时调用.使用此方法将服务添加到容器.公共无效ConfigureServices(IServiceCollection服务){services.AddAuthentication(AzureADB2CDefaults.AuthenticationScheme).AddAzureADB2C(options => Configuration.Bind("AzureAdB2C"，options));services.AddControllersWithViews();services.AddRazorPages();}//此方法由运行时调用.使用此方法来配置HTTP请求管道.公共无效配置(IApplicationBuilder应用程序，IWebHostEnvironment env){如果(env.IsDevelopment()){app.UseDeveloperExceptionPage();}别的{app.UseExceptionHandler("/Home/Error");//HSTS的默认值为30天.您可能要针对生产方案更改此设置，请参见https://aka.ms/aspnetcore-hsts.app.UseHsts();}app.UseHttpsRedirection();app.UseStaticFiles();app.UseRouting();app.UseAuthentication();app.UseAuthorization();app.UseEndpoints(endpoints =>{endpoints.MapControllerRoute(名称:"test"，模式:测试/{controller = Map}/{action = Index}/{id?}")；endpoints.MapControllerRoute(名称:默认"，模式:"{controller = Home}/{action = Index}/{id?}")；endpoints.MapRazorPages();});}} 

在MapController.cs中:

  [Area("Test")][Route("test/[controller]")]公共类MapController:控制器{公共IActionResult Index(){返回View();}[Route("[action]")]公共IActionResult LoadNearbySitesAsync(){返回Ok("data");}} 

当我尝试访问

当我尝试使用jQuery $.get 函数访问 LoadNearbySitesAsync 方法时，我也收到HTTP 404异常.

之前，我使用的是ASP.NET Core 2.2，并且工作正常.现在，我切换到ASP.NET Core 3.1和新的Endpoints东西，我无法使它正常工作.

我尝试了属性 [Area] 和 [Route] 的不同组合，甚至添加了 [Route("[action]")] LoadNearbySitesAsync 方法上的code>属性，到目前为止没有任何效果.

知道我在这里缺少什么吗?

解决方案

1. 从 LoadNearbySitesAsync 操作中删除 [Route("[action]")] 并删除 [Route("Test/[controller]")] 来自控制器
2. 将 MapControllerRoute 更改为 MapAreaControllerRoute

  app.UseEndpoints(endpoints => {endpoints.MapControllers();endpoints.MapAreaControllerRoute(测试"，测试"，"Test/{controller = Map}/{action = Index}/{id?}")；endpoints.MapControllerRoute(名称:默认"，模式:"{controller = Home}/{action = Index}/{id?}")；}); 

3. 将操作名称从 LoadNearbySitesAsync 更改为 LoadNearbySites 或调用此网址 https://localhost:44319/Test/Map/LoadNearbySites

I have the following simple solution, with one Area named Test:

In my Startup.cs:

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    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.AddAuthentication(AzureADB2CDefaults.AuthenticationScheme)
            .AddAzureADB2C(options => Configuration.Bind("AzureAdB2C", options));
        services.AddControllersWithViews();
        services.AddRazorPages();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }
        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseAuthentication();
        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "test",
                pattern: "Test/{controller=Map}/{action=Index}/{id?}");

            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");
            endpoints.MapRazorPages();
        });
    }
}

And in the MapController.cs:

[Area("Test")]
[Route("test/[controller]")]
public class MapController : Controller
{
    public IActionResult Index()
    {
        return View();
    }

    [Route("[action]")]
    public IActionResult LoadNearbySitesAsync()
    {
        return Ok("data");
    }
}

When I try to reach https://localhost:44319/Test/Map/Index, the Index page is showing up. When I try to reach https://localhost:44319/Test/Map/LoadNearbySitesAsync, I get an HTTP 404 exception:

I also get an HTTP 404 exception when I try accessing the LoadNearbySitesAsync method with jQuery $.get function.

Before, I was using ASP.NET Core 2.2 and it was working fine. Now that I switched to ASP.NET Core 3.1 and the new Endpoints stuff, I can't get this to work.

I tried different combinations of attributes [Area] and [Route], I even added a [Route("[action]")] attribute on the LoadNearbySitesAsync method, nothing worked so far.

Any idea what I am missing here?

解决方案

1. Remove [Route("[action]")] from LoadNearbySitesAsync action and remove [Route("Test/[controller]")] from controller
2. Change the MapControllerRoute to MapAreaControllerRoute

app.UseEndpoints(endpoints => {
        endpoints.MapControllers();
        endpoints.MapAreaControllerRoute(
            "Test",
            "Test",
            "Test/{controller=Map}/{action=Index}/{id?}");

        endpoints.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}");  
});

3. change the name of action from LoadNearbySitesAsync to LoadNearbySites or call this url https://localhost:44319/Test/Map/LoadNearbySites
