ASP.NET MVC初始化控制器和编程呼吁采取行动 [英] ASP.NET MVC initialize Controller and call action programatically
问题描述
我建立一个计划的作业控制器 - 这些工作将调用控制器和动作捕捉的结果。我宁愿这一切都发生在后台,不涉及HTTP调用。
它有点像单元测试会发生什么 - 例如:
VAR控制器=新的TestController();
VAR的结果= controller.Index(TestParameter)作为的ViewResult;
的问题是在本实施例的控制器和动作不是动态的,没有人知道如何初始化控制器和调用与控制器和行动作为字符串paramater名称的行动?比如 -
公众的ActionResult运行(字符串controllerName,串actionName)
{
无功控制器=新控制器(controllerName);
VAR的结果= controller.action(actionName)(TestParameter)作为的ViewResult。
返回内容(结果);
}
使用的ControllerFactory
ActionDescriptor 来动态地执行操作沿>:
公众的ActionResult运行(字符串controllerName,串actionName)
{
//获取控制
VAR ctrlFactory = ControllerBuilder.Current.GetControllerFactory();
VAR CTRL = ctrlFactory.CreateController(this.Request.RequestContext,controllerName)作为控制器;
变种ctrlContext =新的ControllerContext(this.Request.RequestContext,CTRL);
变种ctrlDesc =新ReflectedControllerDescriptor(ctrl.GetType());
//获取行动
VAR actionDesc = ctrlDesc.FindAction(ctrlContext,actionName);
//执行
VAR的结果= actionDesc.Execute(ctrlContext,新的字典<字符串对象>
{
{参数名称,TestParameter}
})为的ActionResult;
//返回其他行动结果作为当前动作的结果
返回结果;
}
请参阅的 MSDN
I am building a scheduled jobs controller - these jobs will call a Controller and an Action capturing the result. I would rather have all this happen on the backend and not involve http calls.
Its kind of like what happens with Unit testing - for instance:
var controller = new TestController();
var result = controller.Index("TestParameter") as ViewResult;
The issue is in this example the controller and action are not dynamic, does anyone know how to initialize a controller and call an action with the name of the controller and action as string paramater? Such as -
public ActionResult run(string controllerName, string actionName)
{
var controller = new Controller(controllerName);
var result = controller.action(actionName).("TestParameter") as ViewResult;
return Content(result);
}
Use the ControllerFactory
along with the ActionDescriptor
to dynamically execute the action:
public ActionResult Run(string controllerName, string actionName)
{
// get the controller
var ctrlFactory = ControllerBuilder.Current.GetControllerFactory();
var ctrl = ctrlFactory.CreateController(this.Request.RequestContext, controllerName) as Controller;
var ctrlContext = new ControllerContext(this.Request.RequestContext, ctrl);
var ctrlDesc = new ReflectedControllerDescriptor(ctrl.GetType());
// get the action
var actionDesc = ctrlDesc.FindAction(ctrlContext, actionName);
// execute
var result = actionDesc.Execute(ctrlContext, new Dictionary<string, object>
{
{ "parameterName", "TestParameter" }
}) as ActionResult;
// return the other action result as the current action result
return result;
}
