th1*_*ey3 4 nancy .net-core dotnet-cli
我正在尝试使用NancyFX(clint-eastwood)dotnetcore1.1和dotnet-cli 1.0.0-rc4-004771.我目前的项目结构是 -
CustomBootstrapper.cs
HomeModule.cs
index.sshtml
nancyapp.csproj
Program.cs
Startup.cs
代码是 -
<Project Sdk="Microsoft.NET.Sdk.Web">

<PackageReference Include="Microsoft.AspNetCore.Owin">

CustomBootstrapper.cs 目前是空的.
当我尝试Get("/test/{name}", args => new Person() { Name = args.name });从休息客户端访问时,我得到了预期的结果.
但是,当我尝试访问root或者Get("/", _ => { return View["index.sshtml"]; });,我收到500服务器错误说 -
错误详细信息目前已禁用.要启用它,请将TraceConfiguration.DisplayErrorTraces设置为true.例如,通过覆盖Bootstrapper的Configure方法并调用environment.Tracing(enabled:false,displayErrorTraces:true)
我尝试按照错误消息中的说明进行操作,并通过包含以下代码启用错误跟踪 CustomBootstrapper.cs
protected override void ApplicationStartup(Nancy.TinyIoc.TinyIoCContainer container, IPipelines pipelines)
{
var environment = GetEnvironment();
environment.Tracing(true, true);
}
但是在尝试运行应用程序时出现以下错误 dotnet run

我不确定是什么导致错误或如何启用跟踪.有人可以帮忙吗？

这里有两个问题:
IRootPathProvider和返回提供根路径Directory.GetCurrent().public override void Configure(INancyEnvironment environment)添加密钥,因此您将获得异常.| 归档时间： |
