我想用和dotnet-cli 1.0.0-rc4-004771使用NancyFX（clint-eastwood）。我目前的项目结构是 -南希500服务器错误dotnetcore和kestrel

CustomBootstrapper.cs 
HomeModule.cs 
index.sshtml 
nancyapp.csproj 
Program.cs 
Startup.cs

和代码是 -

nancyapp.csproj

<Project Sdk="Microsoft.NET.Sdk.Web"> 
    <PropertyGroup> 
    <TargetFramework>netcoreapp1.1</TargetFramework> 
    </PropertyGroup> 
    <ItemGroup> 
    <PackageReference Include="Microsoft.AspNetCore.Owin"> 
     <Version>1.1.0</Version> 
    </PackageReference> 
    <PackageReference Include="Microsoft.AspNetCore.Server.Kestrel"> 
     <Version>1.1.0</Version> 
    </PackageReference> 
    <PackageReference Include="Nancy"> 
     <Version>2.0.0-clinteastwood</Version> 
    </PackageReference> 
    </ItemGroup> 
</Project>

的Program.cs

using System.IO; 
using Microsoft.AspNetCore.Builder; 
using Microsoft.AspNetCore.Hosting; 

namespace nancyapp 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      var host = new WebHostBuilder() 
       .UseKestrel() 
       .UseContentRoot(Directory.GetCurrentDirectory()) 
       .UseStartup<Startup>() 
       .Build(); 

      host.Run(); 
     } 
    } 
}

Startup.cs

using Microsoft.AspNetCore.Builder; 
using Nancy.Owin; 

namespace nancyapp 
{ 
    public class Startup 
    { 
     public void Configure(IApplicationBuilder app) 
     { 
      app.UseOwin(x => x.UseNancy()); 
     } 
    } 
}

个

HomeModule.cs

using Nancy; 

namespace nancyapp 
{ 
    public class HomeModule : NancyModule 
    { 
     public HomeModule() 
     { 
      Get("/", _ => { return View["index.sshtml"]; }); 
      Get("/test/{name}", args => new Person() { Name = args.name }); 
     } 
    } 

    public class Person 
    { 
     public string Name { get; set; } 
    } 
}

index.sshtml

<!DOCTYPE html> 
<html lang="en"> 
<head> 
    <meta charset="UTF-8"> 
    <title>Document</title> 
</head> 
<body> 
    Welcome to Nancy App. 
</body> 
</html>

CustomBootstrapper.cs目前是空的。

当我尝试从休息客户端访问Get("/test/{name}", args => new Person() { Name = args.name });时，我得到了预期的结果。

然而，当我尝试访问根或Get("/", _ => { return View["index.sshtml"]; });，我得到一个500服务器错误说 - 目前

错误细节被禁用。要启用它，请将 TraceConfiguration.DisplayErrorTraces设置为true。例如，通过重写你的引导程序的配置方法，并呼吁 environment.Tracing（启用：假的，displayErrorTraces：真）

我试图在错误信息的指令之后，使误差通过在CustomBootstrapper.cs下面的代码跟踪试图运行与dotnet run

    key has already been added. Key: Nancy.TraceConfiguration at

    nancyapp.Program.Main(String[] args) in D:\TempWork\nancyapp\Program.cs:line 11

应用程序时

protected override void ApplicationStartup(Nancy.TinyIoc.TinyIoCContainer container, IPipelines pipelines) 
{ 
    var environment = GetEnvironment(); 
    environment.Tracing(true, true); 
}

但后来我得到以下错误0

我不确定是什么原因导致错误或如何启用跟踪。谁能帮忙？

当您尝试从浏览器访问'url'时会发生什么？请显示'GetEnvironment'的代码。 – zulq

的两个问题在这里：

500，是因为认为没有被发现，你需要做的是通过实施IRootPathProvider提供根路径并返回Directory.GetCurrent()。
其次要启用跟踪，你需要public override void Configure(INancyEnvironment environment)这增加了键，因此你是你得到的例外。
