c# - MVC 6 - request.path の構築中に Krestel がエラーをスローし、呼び出しをコントローラーにルーティングするための回避策

Question

次の例外が発生します。

System.ArgumentException

   at Microsoft.AspNet.Http.PathString..ctor(String value)
   at Microsoft.AspNet.Http.Internal.DefaultHttpRequest.get_Path()
   at Microsoft.AspNet.StaticFiles.Helpers.TryMatchPath(HttpContext context,   PathString matchUrl, Boolean forDirectory, PathString& subpath)

the Request METHOD is GET
 HTTP Version HTTP/1.1
Content-Type : application/x-www-form-urlencoded
Accept-Encoding : {gzip}

どんな助けでも大歓迎です。

public Startup(IHostingEnvironment env)

        .AddJsonFile("XDCRInfo.json")
        .AddEnvironmentVariables();
    Configuration = builder.Build();

public void ConfigureServices(IServiceCollection services)

    var policy = new Microsoft.AspNet.Cors.Infrastructure.CorsPolicy();

    policy.SupportsCredentials = true;

    app.Use(next => async context => 
        // Keep the original stream in a separate
        // variable to restore it later if necessary.
        var stream = context.Request.Body;

        // Optimization: don't buffer the request if
        // there was no stream or if it is rewindable.
        if (stream == Stream.Null || stream.CanSeek)
        {
            await next(context);
            return;

            { 
                // Copy the request stream to the memory stream.
                await stream.CopyToAsync(buffer);

                // Rewind the memory stream.
                buffer.Position = 0L;

                // Replace the request stream by the memory stream.
                context.Request.Body = buffer;

                // Invoke the rest of the pipeline.
                await next(context);
            }
        }
        catch (System.ArgumentException ex)
        {
            var Frame = (Microsoft.AspNet.Server.Kestrel.Http.Frame)context.Features;

            Console.WriteLine(Frame.RequestUri);
        }
        finally
        {
            // Restore the original stream.
            context.Request.Body = stream;
            Console.WriteLine(context.Request);
        }
    });

    app.UseCors("CrossOrigin");

    app.UseMvc();
}

App.useエラーをキャプチャするために使用されました。そうしないと、リクエストを見ることができませんでした。
