如何根据环境制作一些URL映射？

Question

获取HTTP状态代码500时,我想根据运行环境显示2个不同的页面.

在发展模式,我想显示stackStrace页(如默认Grails的500错误页面),并在生产模式,我想显示一个正式的"内部错误"页面.

有可能,我该怎么做？

Answer 1

您可以在其中执行特定于环境的映射 UrlMappings.groovy

grails.util.GrailsUtil 救援

它不漂亮,但我认为它将解决你的问题

例如

import grails.util.GrailsUtil

class UrlMappings {
    static mappings = {


        if(GrailsUtil.getEnvironment() == "development") {

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

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

        if(GrailsUtil.getEnvironment() == "test") {
            "/$controller/$action?/$id?"{
                constraints {
                    // apply constraints here
                }
            }

            "/"(view:"/testIndex")
            "500"(view:'/error')

        }



        if(GrailsUtil.getEnvironment() == "production") {
            "/$controller/$action?/$id?"{
                constraints {
                    // apply constraints here
                }
            }

            "/"(view:"/prodIndex")
            "500"(view:'/error')

        }
    }
}

Answer 2

可能有一种更简洁的方法可以做到这一点,但我将错误代码映射到控制器并在那里处理逻辑:

class UrlMappings {

   static mappings = {

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

      "/"(view:"/index")

      "403"(controller: "errors", action: "accessDenied")
      "404"(controller: "errors", action: "notFound")
      "405"(controller: "errors", action: "notAllowed")
      "500"(view: '/error')
   }
}

然后创建相应的控制器(grails-app/conf/controllers/ErrorsController.groovy):

import grails.util.Environment

class ErrorsController extends AbstractController {

   def accessDenied = {}

   def notFound = {}

   def notAllowed = {}

   def serverError = {
      if (Environment.current == Environment.DEVELOPMENT) {
         render view: '/error'
      }
      else {
         render view: '/errorProd'
      }
   }
}

您需要在grails-app/views/errors(accessDenied.gsp,notFound.gsp等)以及新的grails-app/views/errorProd.gsp中创建相应的GSP.通过为所有错误代码路由到控制器方法,您可以更轻松地将逻辑添加到其他错误代码处理程序中.
