Procedures for the. NET MYMVC Framework to perform action

In the Ajaxhandlerfactory GetHandler method, you will eventually create a actionhandler, which is a httphandler, which will be called in the 15th step of the pipeline (referencing the blog "Write your own service framework with ASP." In the order).

Note: The GetHandler method of Ajaxhandlerfactory is called in the 10th step, and the 12th step is to prepare the session (non-in-process mode), so you must decide how to use the session before the 12th step.

All action codes are executed in Actionhandler:

Internal class actionhandler:ihttphandler{    internal Invokeinfo invokeinfo;    public void ProcessRequest (HttpContext context)    {        //Call the Core tool class, execute action        actionexecutor.executeaction ( Context, this. invokeinfo);    }

The ExecuteAction implementation process is as follows:

internal static void ExecuteAction (HttpContext context, Invokeinfo Vkinfo) {if (context = = null) throw new Argu    Mentnullexception ("context");    if (Vkinfo = = null) throw new ArgumentNullException ("Vkinfo");    Call Method Object result = executeactioninternal (context, vkinfo);    Set OutputCache Outputcacheattribute OutputCache = vkinfo.getoutputcachesetting ();    if (OutputCache! = null) Outputcache.setresponsecache (context);    The return result of the processing method Iactionresult Executeresult = result as Iactionresult;    if (Executeresult! = null) {executeresult.ouput (context); } else {if (result! = NULL) {//plain type result context.            Response.ContentType = "Text/plain"; Context. Response.Write (Result.        ToString ()); }}}internal Static Object Executeactioninternal (HttpContext context, Invokeinfo Info) {//Prepare parameters to be passed to the calling method object[] Parameters = Getactioncallparameters (context, info.    Action); Call the method if (info. Action.Hasreturn) return info. Action.MethodInfo.Invoke (info.    Instance, parameters); else {info. Action.MethodInfo.Invoke (info.        Instance, parameters);    return null; }}

Before I did not say the time to call Setresponsecache (), this time is here: after executing the action.
Once the outputcache has been set, the return value is processed.

In the previous code, there was an important call:

Prepare parameters to be passed to the calling method object[] Parameters = getactioncallparameters (context, info. Action);
