本篇主要講述MVC處理請求時創(chuàng)建Controller和執(zhí)行Action的完整過程。
創(chuàng)建Controller
先查看MvcHandler中處理請求的方法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
{
……
}
}
