ASP.Net Core Web API基于约定的路由？
我错过了什么，我为这个控制器打了404欢迎？ 我真的不想使用基于属性的路由。 我也不希望action成为任何URI的一部分。
我正在使用Visual Studio 2017和.Net Core 1.1。
TestController.cs
using System; using Microsoft.AspNetCore.Mvc; namespace Foo.Controllers { public class TestController : Controller { public long Get() => DateTimeOffset.Now.ToUnixTimeSeconds(); } }
请注意，这适用于[Route("api/Test")]属性。 但我不想使用基于属性的路由。 一旦我取消该属性，我就会得到404。
Startup.cs
namespace Foo { public class Startup { public Startup(IHostingEnvironment env) { var builder = new ConfigurationBuilder() .SetBasePath(env.ContentRootPath) .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true) .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true) .AddEnvironmentVariables(); Configuration = builder.Build(); } public IConfigurationRoot Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { // Add framework services. services.AddMvc(); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { loggerFactory.AddConsole(Configuration.GetSection("Logging")); loggerFactory.AddDebug(); app.UseMvc(routes => { routes.MapRoute( name: "default", template: "api/{controller}/{id?}" ); }); } } }
注意这里也有一些用于Autofac / DI的东西，但是我把它拿出去以消除分心。

这不起作用，因为没有定义映射到操作方法。 AFAIK，您可以使用属性路由实现WebApi REST，就像路由一样，您可以在控制器级别定义它：
[Route("api/[controller]")] public class TestController : Controller { [HttpGet] public long Get() => DateTimeOffset.Now.ToUnixTimeSeconds(); }
更新 ：发现此github问题Web API无法使用基于约定的例程，并且：
对于ASP.NET Core MVC，我们决定采用MVC 5.x的传统路由方法而不是Web API 2.x的方法。 使用传统的路由方法， 路由必须同时指定控制器和动作 。
您可以将路径模板更改为
template: "api/{controller}/{action}/{id?}"
但在这种情况下，您的URL将是/api/test/get 。
更新2 （基于指南 ）：您可以包含Microsoft.AspNetCore.Mvc.WebApiCompatShim的NuGet包，仍然使用ApiController。 如果您对它的作用感到好奇，那么代码就在GitHub上。 然后，您可以定义WebApi路由：
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { app.UseMvc(routes => { routes.MapWebApiRoute("DefaultApi", "api/{controller}/{id?}"); }); }
