如何从Grails中的UrlMapping中排除特定关键字？ [英] How to exclude specific keywords from UrlMapping in Grails?

问题描述

我在Grails中使用以下URL映射：

 / $ id{
 controller =user 
 action =show
} 
  

可映射网址，例如 mydomain.com/someusername

如何将约束附加到url映射以排除诸如login，logout等关键字

即，
mydomain.com/someusername应该路由到mydomain.com/user/show/someusername，
mydomain.com/login不应路由至mydomain.com/user/show/login。

解决方案

您可以使用这个映射的约束：

 / $ id{
 controller =user
 action =show
 constraints {
 //在url映射中为$ id添加一个验证器
 id（validator：{
 return！（it in ['login'，'logout']）
}）
} 
} 
  

I use the following url mapping in Grails:

"/$id"{
  controller = "user"
  action = "show"
}       

to map urls like mydomain.com/someusername

How do I attach constrains to the url mapping to exclude keywords like "login", "logout",...

I.e., mydomain.com/someusername should route to mydomain.com/user/show/someusername, mydomain.com/login should not route to mydomain.com/user/show/login.

解决方案

You can use contrainsts for this mapping:

"/$id"{
  controller = "user"
  action = "show"
  constraints {
    //add a validator for $id from url mapping
    id(validator: {
        return !(it in ['login', 'logout'])
    })
  }
}
