Grails UrlMapping重定向以保持DRY [英] Grails UrlMapping Redirect to keep DRY

问题描述

我正在使用 Grails 2.1.1 ，并希望添加一些映射到控制器操作的自定义URL。

我可以这样做，但原始映射仍然有效。

例如，我在中创建了一个映射 add-property-to-directory UrlMappings 如下：

  class UrlMappings {
 
 static mappings = { 
/ add-property-to-directory（controller：property，action：create）
/ $ controller / $ action？/ $ id？{
 constraints {
 //在这里应用约束
} 
} 
 
/（view：/ index）
500（view：' / error'）
} 
} 
  

现在，我可以点击 / mysite / add-property-to-directory ，它会执行 PropertyController.create ，如我所料。然而，我仍然可以打到 / mysite / property / create ，它会执行相同的 PropertyController.create 方法。

本着DRY的精神，我想做一个301重定向从 / mysite / property / create 到 / mysite的/附加属性到目录。

我找不到在 UrlMappings.groovy 中执行此操作的方法。有没有人知道我可以在Grails中实现这一点的方法？

非常感谢！

更新

以下是我根据Tom的回答实施的解决方案：

UrlMappings.groovy

  class UrlMappings {
 
 static mappings = {
 
/ add-property-to目录（控制器：属性，操作：创建）
/ property / create{
 controller =redirect
 destination =/ add-property-to-目录
} 
 
 
/ $ controller / $ action？/ $ id？{
 constraints {
 // apply constraints here 
 
 
 $ b/（view：/ index）
500（view：'/ error'）
} 
} 
  

RedirectController.groovy

  class RedirectController {
 
 def index（）{
 redirect（url：params.de stination，permanent：true）
} 
} 
  

解决方案可以实现这一点：

 / $ controller / $ action？/ $ id？ （
 controller：'myRedirectControlller'，action：'myRedirectAction'，params：[controller：$ controller，action：$ action，id：$ id] 
）
 
/ user / list（controller：'user'，action：'list'）
  

你可以在params中得到normallny的值：

  log.trace'myRedirectController.myRedirectAction：'+ params.controller +'，'+ params.action +'，'+ params.id 
  

I am working with Grails 2.1.1 and would like to add a handful of customized URLs that map to Controller Actions.

I can do that, but the original mapping still works.

For example, I created a mapping add-property-to-directory in my UrlMappings as follows:

class UrlMappings {

    static mappings = {
        "/add-property-to-directory"(controller: "property", action: "create")
        "/$controller/$action?/$id?"{
            constraints {
                // apply constraints here
            }
        }

        "/"(view:"/index")
        "500"(view:'/error')
    }
}

Now, I can hit /mysite/add-property-to-directory and it will execute PropertyController.create, as I would expect.

However, I can still hit /mysite/property/create, and it will execute the same PropertyController.create method.

In the spirit of DRY, I would like to do a 301 Redirect from /mysite/property/create to /mysite/add-property-to-directory.

I could not find a way to do this in UrlMappings.groovy. Does anyone know of a way I can accomplish this in Grails?

Thank you very much!

UPDATE

Here is the solution that I implemented, based on Tom's answer:

UrlMappings.groovy

class UrlMappings {

    static mappings = {

        "/add-property-to-directory"(controller: "property", action: "create")
        "/property/create" {
            controller = "redirect"
            destination = "/add-property-to-directory"
        }


        "/$controller/$action?/$id?"{
            constraints {
                // apply constraints here
            }
        }

        "/"(view:"/index")
        "500"(view:'/error')
    }
}

RedirectController.groovy

class RedirectController {

    def index() {
        redirect(url: params.destination, permanent: true)
    }
}

解决方案

It is possible to achieve this:

"/$controller/$action?/$id?" (
    controller: 'myRedirectControlller', action: 'myRedirectAction', params:[ controller: $controller, action: $action, id: $id ]
)

"/user/list" ( controller:'user', action:'list' )

and in the action you get the values normallny in params:

log.trace 'myRedirectController.myRedirectAction: ' + params.controller + ', ' + params.action + ', ' + params.id
