c# - [ASP.net]MVC 在我的 Controller 之前做什么？

Question

我的 MVC Controller 出现了一些奇怪的性能问题，或者更确切地说是在它之前？

根据 Mini Profiler 输出，在到达我的 Controller 之前有 120 毫秒的开销。

有人知道为什么会这样吗？这是在服务器上(非本地)，设置了 Compilation debug=false，所以这不是在 release 模式下运行的问题。

它之后的所有内容，我都可以调整/修改，但之前呢？我迷路了..

想法??

在一些性能工具之后，我遇到了 enter link description here & enter link description here结果如下:

unity 会导致一些问题吗？

Answer 1

你应该看看The ASP.NET MVC Pipeline

ASP.NET MVC Pipeline可以分为以下几个部分-

• 应用程序初始化 - 在此方法中，您可以将 Route 对象添加到静态 RouteTable.Routes 集合(属于 RouteCollection 类型)。

• 路由部分 – 路由模块尝试将传入的 URL 与路由表，并调用相应的IRouteHandler。

• Controller 创建 – IControllerFactory 创建一个实例基于路由参数和默认命名的 Controller 约定。

• Action Execution – IActionInvoker 标识要执行的方法执行时，IModelBinder 验证并绑定(bind)方法参数IFilterProvider 发现要应用的过滤器。那个行动返回类型 ActionResult。

• View – IViewEngine 实例化正确的 View 引擎和模型传递给 View 。使用模型验证提供程序，检索验证规则以创建客户端验证脚本以及远程验证脚本
