razor - vNext : Console app that uses razor views without hosting

Question

我正在创建执行一些文件转换的控制台应用程序。这些转换很容易完成，从输入文件创建模型，然后为输出执行 Razor 模型。

为了让它在 IDE 中工作，我使用了 Visual Studio 2015 预览版并创建了一个使用 MVC 的 vnext 控制台应用程序。 (然后，您将获得开箱即用的 Razor 支持)。为了让这一切正常工作，您需要托管 MVC 应用程序，而最便宜的方式是通过 WebListener 托管。所以我托管 MVC 应用程序，然后通过 "http://localhost:5003/etc/etc" 调用它获取构建输出的渲染 View 。

但是控制台应用程序不应该监听/使用端口。它只是一个用于文件转换的命令行工具。如果多个实例同时运行，它们将争取在同一端口上托管页面。 (这可以通过动态选择端口来防止，但这不是我要找的)

所以我的问题是如何在不使用端口但尽可能多地使用 vnext 框架的情况下使其工作。

简而言之:如何使用我在控制台应用程序中传递模型的 cshtml 文件，该应用程序不使用使用 vnext razor 引擎的端口。

这是我目前使用的一些代码:

            _hostServiceProvider = hostServiceProvider;
        }

        {
            using (var httpClient = new HttpClient())
            {
                httpClient.BaseAddress = new Uri("http://localhost:5003/home/svg?idx=1");
                httpClient.DefaultRequestHeaders.Accept.Clear();
                httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/xml"));
                return await httpClient.GetStringAsync("");
            }
        }

        public Task<int> Main(string[] args)
        {
            var config = new Configuration();
            config.AddCommandLine(args);

            var serviceCollection = new ServiceCollection();
            serviceCollection.Add(HostingServices.GetDefaultServices(config));
            serviceCollection.AddInstance<IHostingEnvironment>(new HostingEnvironment() { WebRoot = "wwwroot" });
            var services = serviceCollection.BuildServiceProvider(_hostServiceProvider);

            var context = new HostingContext()
            {
                Services = services,
                Configuration = config,
                ServerName = "Microsoft.AspNet.Server.WebListener",
                ApplicationName = "ConsoleTest"
            };

            var engine = services.GetService<IHostingEngine>();
            if (engine == null)
            {
                throw new Exception("TODO: IHostingEngine service not available exception");
            }

            using (engine.Start(context))
            {
                var tst = GetWebpageAsync();
                tst.Wait();
                File.WriteAllText(@"C:\\result.svg", tst.Result.TrimStart());

                Console.WriteLine("Started the server..");
                Console.WriteLine("Press any key to stop the server");
                Console.ReadLine();
            }
            return Task.FromResult(0);
        }
    }

我使用以下代码解决了它:

程序.cs

using System;
using System.Threading.Tasks;
using Microsoft.AspNet.TestHost;
using Microsoft.AspNet.Builder;
using Microsoft.Framework.Runtime.Infrastructure;

namespace ConsoleTest
{
    public class Program
    {
        private Action<IApplicationBuilder> _app;
        private IServiceProvider _services;

        public async Task<string> TestMe()
        {
            var server = TestServer.Create(_services, _app);
            var client = server.CreateClient();
            return await client.GetStringAsync("http://localhost/home/svg?idx=1");
        }

        public void Main(string[] args)
        {
            _services = CallContextServiceLocator.Locator.ServiceProvider;
            _app = new Startup().Configure;

            var x = TestMe();
            x.Wait();
            Console.WriteLine(x.Result);

            Console.ReadLine();
        }
    }
}
