我怎么能执行普通code为每个请求？ [英] How can I execute common code for every request?

问题描述

是否有可能找到像的Page_Load 功能？我有MVC应用程序，我需要运行一些code每次加载页面时，或重新加载，否则我调用一些控制器。一切类的一个共享功能？

Is there any possibility to find function like Page_Load? I have MVC application and I need run some code every page is loaded, or reloaded, or I call some controller. One shared function for everything classes?

我尝试的Application_Start，但只执行首次运行的应用程序。我搜索了一些像的BeginRequest ，不过这个功能已经调用好几次，我只需要第一次，当我加载页面，我需要结束的功能，如构造函数和析构函数为整个项目

I try Application_Start, but this execute only for first time application run. I search some like BeginRequest, but this function have been call several times, I need only first, when I load page and I need end function, like constructor and destructor for whole project.

下面是示例code。

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
    }  
}

的document.ready 不是我的情况。并调用函数的每个控制器是最后的选择。任何其他函数被调用之前，必须执行code。而所有年底前，我需要运行结束的功能。例如，在首先我需要创造的MySQL Connector所有类共享。而在最后，我需要关闭MySQL连接。

document.ready isn't my case. And call function every controller is last option. The code must be executed before any other function have been called. And before all end, i need run end function. For example, at first I need created mysql connector shared for all classes. And at end I need close mysql connection.

推荐答案

请所有的控制器从定制BaseController继承：

Make all your controllers inherit from a custom BaseController:

public class BaseController : Controller
{
    protected override void OnActionExecuting(ActionExecutingContext context)
    {
        base.OnActionExecuting(context);
        // your code here
    }
}

public class HomeController : BaseController // instead of Controller
{
    // ...
}
