将参数从控制器传递给拦截器在Grails 3.x中的（）操作之后

Question

我需要将一个参数从控制器传递给拦截器的after（）动作。我怎样才能做到这一点？

Answer 1

在拦截器关闭之前，您有请求和响应对象可用，但请求/响应对象的作用域在以模型对象为参数的关闭之后执行完成。

class YourInterceptor { 
    boolean before(){ 
    //code before reaching respective controller 
     return true 
    } 
    //this part is executed before the view is rendered, 
    def afterInterceptor = { model -> 
     def myParam = model.yourParam; 
    } 
} 

You can set the model object used above in your controller as 
public class YourController { 
    //your controller logic 
[yourParam: paramValue] // this map is the model object which contains `the data for your view, this object is the model object that is used in after closure of interceptor.` 
}
