基于ASP.Net Core Web API约定的路由? [英] ASP.Net Core Web API convention-based routing?
问题描述
我为这个控制器打了404，我想念什么?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.
What am I missing that I'm greeted with a 404 for this controller? I really don't want to use attribute-based routing. I also don't want action to be part of any URIs.
我正在使用Visual Studio 2017和.Net Core 1.1.
I'm using Visual Studio 2017 and .Net Core 1.1.
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.但是我不想使用基于属性的路由.而一旦我取消该属性，我就会得到404.
Note that this works with a [Route("api/Test")] attribute. But I don't want to use attribute-based routing. And as soon as I take that attribute off, I get 404s.
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?}"
);
});
}
}
}
请注意，这里还有一些有关Autofac/DI的内容，但我删除了这些内容是为了消除干扰.
Note there's also some stuff in here for Autofac/DI, but I took that out to remove the distraction.

推荐答案
这是行不通的，因为未定义到操作方法的映射. AFAIK，您可以像只使用属性路由一样实现WebApi REST ，并且可以在控制器级别进行定义:
This is not works, as mapping to action method is not defined. AFAIK, you may achieve the WebApi REST like routing ONLY using the attribute routing and you may define it on controller level:
[Route("api/[controller]")]
public class TestController : Controller
{
[HttpGet]
public long Get() => DateTimeOffset.Now.ToUnixTimeSeconds();
}
更新:发现此github问题 Web API无法使用基于惯例的例程和:
Update: have found this github issue Web API not working with convention based routin and:
对于ASP.NET Core MVC，我们决定采用MVC 5.x的常规路由方法，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操作.
您可以将路由模板更改为
You may change route template to
template: "api/{controller}/{action}/{id?}"
但是在这种情况下，您的URL将是/api/test/get.
But in this case, your URL will be /api/test/get.
更新2 (基于指南):您可以包括 Microsoft.AspNetCore的NuGet程序包. Mvc.WebApiCompatShim 并仍使用ApiController.如果您是，则代码位于 GitHub 上对它的作用感到好奇.然后，您可以定义WebApi路由:
Update 2 (based on the guide): you can include the NuGet package for Microsoft.AspNetCore.Mvc.WebApiCompatShim and still use ApiController. The code is on GitHub if you are curious as to what it does. Then you can define the WebApi routing:
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
app.UseMvc(routes =>
{
routes.MapWebApiRoute("DefaultApi", "api/{controller}/{id?}");
});
}
