c# - 配置 ASP.NET Core 应用程序的正确顺序是什么？

Question

我有一个带有多个 Web Api Controller 的 ASP.NET Core 应用程序。我不知道是否有某种联系，但该应用程序是使用 VS2015 更新 2 创建的，现在我正在使用 VS2015 更新 3。所以我创建了另一个 Web Api Controller ，当对该 Controller 有查询时，我遇到了这个异常:

System.NotSupportedException: The given path's format is not supported.

   at System.IO.Path.GetFullPath(String path)
   at Microsoft.AspNet.FileProviders.PhysicalFileProvider.GetFullPath(String path)
   at Microsoft.AspNet.FileProviders.PhysicalFileProvider.GetFileInfo(String subpath)
   at Microsoft.AspNet.StaticFiles.StaticFileContext.LookupFileInfo()
   at Microsoft.AspNet.StaticFiles.StaticFileMiddleware.Invoke(HttpContext context)

   at Microsoft.AspNet.Diagnostics.DeveloperExceptionPageMiddleware.<Invoke>d__7.MoveNext()

有趣的是，StaticFileMiddleware 以某种方式参与处理对 Controller 的简单请求。虽然我可以通过调用

更改配置应用程序的顺序来解决问题

app.UseMvc(...

之前

app.UseStaticFiles()

我仍然想知道这是怎么发生的以及配置应用程序的正确顺序是什么。

请记住，所有以前添加的 Controller 都可以在两种配置方式下正常工作，但新 Controller 只能与后者一起工作。

新 Controller 不使用静态文件进行操作。

已编辑路由:在 Controller 中:

[Route("api/[controller]")]
    public class ViewsController : Controller
    {
        [HttpGet("{path}", Name = "Views")]
        public async Task<IActionResult> Get(string path)
        {
            return Json("bla");
        }
    }

在 Startup.cs 中:

app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "angular2app",
                template: "ng/{*.}",
                defaults: new { controller = "Home", action = "Index" });

            routes.MapRoute(
                name: "api",
                template: "api/{controller}/{action}/{id?}");

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

麻烦的请求:

http://localhost:5000/api/Views/blablapath

如果您将 Core2 预览与发布 nuget 混合使用，您必须将静态文件 nuget 添加到您的项目中。 (Core2已经包含了，但还是要加上才能解决一些问题)

Microsoft.AspNetCore.StaticFiles
