Question

我已按照教程tutorial进行操作。我已经读过在我的web应用程序中要执行的第一个文件是startup.cs，但startup.cs只包含以下代码。执行此文件后发生了哪些步骤？我没有看到任何页面打开...谢谢！

using Microsoft.Owin;
using Owin;

[assembly: OwinStartupAttribute(typeof(ContactManager.Startup))]
namespace ContactManager
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
        }
    }
}

Index.cshtml页面：

@{
    ViewBag.Title = "Home Page";
}

<div class="jumbotron">

Answer 1

Startup.cs将通过设置各种服务来初始化您的项目。在这种情况下，它设置身份验证框架。位于Startup.cs的代码只运行一次，这是IIS第一次启动您的网站时。它不会为每个后续请求运行。

当您尝试打开页面时，您的浏览器发出HTTP GET请求，然后由MVC路由管理系统拦截和处理。尝试找到您的路由配置（可能在名为RouteConfig.cs的文件中）。您的路由配置将指示默认情况下将加载哪个视图。

例如;以下路线告诉我，我的默认视图将是Index

中HomeController.cs方法生成的内容

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
