我创建了一个.NET Core MVC Web app。我将 Startup 类移动到一个单独的库项目中，并将 MVC 项目中的依赖项添加到库项目上。在第三个命令行应用程序中，我可以使用此启动类。在我更新 MVC 项目以使用库项目中的 Startup 类而不是 Web 项目中的默认 Startup 类后，Visual Studio 中的 Web 服务器会为我提供 404。
找不到此本地主机页面 找不到网址的网页：https://localhost:44323/HTTP 错误 404
我可以通过 Startup.ConfigureServices(( 中此块的末尾调试进程，但随后调试器只是停止(无例外(，浏览器显示 404 页面。我的操作中的断点永远不会触发。
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
下面是启动类。这基本上是直接从Visual Studio模板复制的，并添加了DoWebStuff属性，CustomerServiceCollectionExtensions和DeliveryStackServiceCollectionExtensions ConfigureContentstackRepository((调用，以及catchall路由(我只是在测试(。
namespace Customer.Core.Configuration
{
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Deliverystack.Contentstack.Core.Configuration;
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
if (DoWebStuff)
{
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
// Microsoft.Extensions.DependencyInjection.AddMvc(services).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}
// IMPORTANT: First configure deserialization from JSON.
CustomerServiceCollectionExtensions.ConfigureSerialization(services, Configuration);
// then Add ContenstackOptions (connection details), ContentstackClient, and IRepository.
DeliverystackServiceCollectionExtensions.ConfigureContentstackRepository(
services,
Configuration);
}
public bool DoWebStuff { get; set; }
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (DoWebStuff)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseCookiePolicy();
app.UseMvc(routes =>
{
routes.MapRoute(
"default",
"{*url}",
new {controller = "Home", action = "Index"});
});
// app.UseMvc(routes =>
// {
// routes.MapRoute(
// name: "default",
// template: "{controller=Home}/{action=Index}/{id?}");
// });
}
}
}
}
以下是我如何启动命令行工具，该工具适用于此 Startup 类：
namespace scratch
{
using System;
using System.Collections;
using System.Collections.Generic;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting.Internal;
using Deliverystack.Contentstack.Core.Models;
using Deliverystack.Contentstack.Core.Repositories;
using Deliverystack.Core.Repositories;
using Contentstack.Core;
using Contentstack.Core.Models;
using Customer.Core.Configuration;
using Customer.Core.Models.Entries.DemoPage;
using Customer.Core.Models.Entries.DemoPage.DemoBlocks;
class Program
{
static void Main(string[] args)
{
HostingEnvironment env = new HostingEnvironment();
//TODO: env.ContentRootPath = Directory.GetCurrentDirectory();
//TODO: env.EnvironmentName = "Development";
IConfiguration configuration = new ConfigurationBuilder().AddJsonFile(
"appsettings.json",
optional: false,
reloadOnChange: true).Build();
Startup startup = new Startup(configuration); // this is in another project/assembly
startup.DoWebStuff = false; // can't add parameters to constructor
ServiceCollection serviceCollection = new ServiceCollection();
startup.ConfigureServices(serviceCollection);
using (var provider = serviceCollection.BuildServiceProvider())
{
这是我尝试共享到命令行和我们的应用程序的启动类：
namespace Customer.Core.Configuration
{
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Deliverystack.Contentstack.Core.Configuration;
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
if (DoWebStuff)
{
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
// Microsoft.Extensions.DependencyInjection.AddMvc(services).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}
// IMPORTANT: First configure deserialization from JSON.
CustomerServiceCollectionExtensions.ConfigureSerialization(services, Configuration);
// then Add ContenstackOptions (connection details), ContentstackClient, and IRepository.
DeliverystackServiceCollectionExtensions.ConfigureContentstackRepository(
services,
Configuration);
}
public bool DoWebStuff { get; set; }
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (DoWebStuff)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseCookiePolicy();
app.UseMvc(routes =>
{
routes.MapRoute(
"default",
"{*url}",
new {controller = "Home", action = "Index"});
});
}
}
}
}
在 ASP.NET Core MVC 应用中，是否有任何理由不能使用单独库中的启动类？为什么调试器似乎崩溃了？为什么在这种情况下我会得到 404？似乎 ASP.NET 已经崩溃了。我可以在哪里查找日志？

我可能有更多的信息。我写了一个命令脚本(.cmd 文件(。

所以我想问题是，这个 Web 服务器是否与 Visual Studio 使用的服务器相同(在这种情况下，原因可能相同(，以及如何禁用此尝试的 SSL 或其他安全内容。
我从来没有弄清楚这一点，但放弃了，因为我认为控制台和 Web 项目不应该使用相同的 Startup。控制台项目将需要一堆依赖项，它不应该只是禁用由启动启用的 Web 功能。必须有更好的方法来管理共享给两者的任何配置/代码。
