本篇主要讲述MVC处理请求时创建Controller和执行Action的完整过程。
创建Controller
先查看MvcHandler中处理请求的方法BeginProcessRequest：
protected internal virtual IAsyncResult BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, object state)
{
IController controller;
IControllerFactory factory;
ProcessRequestInit(httpContext, out controller, out factory);
IAsyncController asyncController = controller as IAsyncController; if (asyncController != null)
{
……
} else
{
……
}
}
