使用Kestrel在.NET Core控制台应用程序中返回HTML视图

Question

I've got .Net Core Console application. I've been trying for awhile to make it possible to run Process and listen to port at the same moment and this was my way of doing it:

This is my program.cs class:

 class Program
{
    static void Main(string[] args)
    {
        var ConsOut = Console.Out; 
        Console.SetOut(new StreamWriter(Stream.Null));
        BuildWebHost(args).Start();                    
        Console.SetOut(ConsOut); 
        while (true)
        {
            RunIbit();
        }
    }

    public static IWebHost BuildWebHost(string[] args)
    {
        var config = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: true)
            .AddCommandLine(args)
            .Build();

        var host = new WebHostBuilder()
            .UseKestrel()
            .UseConfiguration(config)
            .UseStartup<Startup>()
            .UseIISIntegration()
           .Build();

        return host;
    }


    public static void RunIbit()
    {
        // Execute Proccess.Start();
    }}

and here is Startup.cs :

public class Startup
{
    public Startup()
    {
        var builder = new ConfigurationBuilder().AddJsonFile("appsettings.json");
        Configuration = builder.Build();
    }

    public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
        services.AddLogging();
        var serviceProvider = services.BuildServiceProvider();
        services.AddSingleton<IConfigurationRoot>(Configuration);

        return WindsorRegistrationHelper.CreateServiceProvider(ContainerManager.Container, services);
    }
     public void Configure(IApplicationBuilder app){
        app.Run(context => {
            return context.Response.WriteAsync("Hello world");
        });
     }
}

Since I want to show the results of the process in a web page I've been wondering whether it's possible to do that somehow instead of writing that Hello world ? Tried adding app.UseMvc() instead of app.Run(context => { return context.Response.WriteAsync("Hello world"); }); but it didn't work with .net core console application and this was the only that worked for me (or at least the one I found) but I couldn't find how to replace that text with html file. Does anyone know a way?

I've been trying for awhile to make it possible to run Process and listen to port at the same moment

short answer :

1. reference packages as dependencies
2. configure services and add a middleware to serve incoming request
3. use your own controllers and views as your need

here's a how-to in details :

I'm not sure whether you want to achieve the goal via MVC solution or static html files , so I provide you with two solutions :

Plan A : As I notice that you have said

tried adding app.UseMvc() ... but id didn't work

let's config a console program with MVC first .

Plan B : config a console with static files .

Just as a reminder , either Plan A or Plan B requires a Microsoft.NET.Sdk.Web SDK . So we must reference correct SDK at frist , namely change the project sdk from Microsoft.NET.Sdk to Microsoft.NET.Sdk.Web :

<Project Sdk="Microsoft.NET.Sdk.Web">
   <!-- ... -->
</Project>

Plan A

1. We need first add package references in your .csproj file :

  <Project Sdk="Microsoft.NET.Sdk.Web"> <PropertyGroup> <TargetFramework>netcoreapp2.0</TargetFramework> </PropertyGroup> <ItemGroup> <Folder Include="wwwroot\\" /> </ItemGroup> <ItemGroup> <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.5" /> </ItemGroup> <ItemGroup> <Content Update="appsettings.json"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> </Content> </ItemGroup> </Project> 

2. and then you can configure MVC in your Startup class:

     public void ConfigureServices(IServiceCollection services) { // ... services.AddMvc(); // add mvc services here // ... } public void Configure(IApplicationBuilder app, IHostingEnvironment env) { app.UseMvcWithDefaultRoute(); // use mvc here app.Run(context => { return context.Response.WriteAsync("Hello world"); }); } 

3. At last , you can add controllers and views file as you need . For instance , if you add a HelloController with a Index action , and the coresponding view file is :

   @{ ViewData["Title"] = "Index"; }

   Index

   it woooooooooooooooooooorks

you will get a response as expected when you access the URL /hello tes-console-with-mvc

Plan B

you can simply add a wwwroot directory in your project and register a middleware with UseStaticFiles() in Configure() method:

public void Configure(IApplicationBuilder app, IHostingEnvironment env){
    // ...

    // app.UseMvcWithDefaultRoute();

    app.UseStaticFiles();     // add a StaticFiles middleware here

    app.Run(async context => {
        await context.Response.WriteAsync("Hello,world");
    });
}
