在 MVC 中使用 ChildActionOnly [英] Using ChildActionOnly in MVC

问题描述

您何时会使用属性 ChildActionOnly?什么是 ChildAction，在什么情况下您希望使用此属性限制操作?

When would you use the attribute ChildActionOnly? What is a ChildAction and in what circumstance would you want restrict an action using this attribute?

推荐答案

ChildActionOnly 属性确保动作方法只能作为子方法调用从视图中.一个动作方法不需要有这个属性作为子动作使用，但是我们倾向于使用此属性来防止操作方法因用户而被调用要求.定义了一个动作方法后，我们需要创建动作时将呈现的内容调用.子操作通常与部分视图相关联，尽管这不是强制性的.

The ChildActionOnly attribute ensures that an action method can be called only as a child method from within a view. An action method doesn’t need to have this attribute to be used as a child action, but we tend to use this attribute to prevent the action methods from being invoked as a result of a user request. Having defined an action method, we need to create what will be rendered when the action is invoked. Child actions are typically associated with partial views, although this is not compulsory.
