Grails 如何使我的URL映射不区分大小写？

默认情况下，Grails在将URL映射到控制器操作或视图时区分大小写

例如，www.mywebsite.com/book/list将起作用，但www.mywebsite.com/book/list将返回404页

---

我能做些什么（欢迎使用代码片段）使我的URL不区分大小写（即www.mywebsite.com/Book/list是一个有效的URL）？

只需简单介绍一下，请尝试以下操作：

static mappings = {
"/$controller/$action?/$id?"{
    controller = controller.toLowerCase()
    action = action.toLowerCase()
}

控制器是一个“保留关键字”，您必须将其重命名为类似“controllerName”的名称

静态映射={ “/$controllerName/$action？/$id？”{ 控制器={“${params.controllerName}”.toLowerCase（）} action=action.toLowerCase（） }

Aaron Saunders在这里有一个很好的解决方案，但他的网站被我屏蔽了。这是他的奇妙解决方案。证实了它在Grails 2.x中非常有效

import org.codehaus.groovy.grails.commons.GrailsClass

class UrlMappings {

    def grailsApplication

    static mappings = {
        "/$controller/$action?/$id?"{
            constraints {
                // apply constraints here
            }
        }
        //Case InSeNsItIvE URLS!!!
        "/$_ctrl/$_action/$id?" {
            controller = {

                def foundControllerMatch = false
                def returnCtrl = params._ctrl   

                grailsApplication.controllerClasses.each { GrailsClass c ->
                    def l_className = c.name.toLowerCase()

                    // find the class
                    if (params._ctrl?.equalsIgnoreCase(l_className) && foundControllerMatch == false) {
                        foundControllerMatch = true
                        returnCtrl = c.getLogicalPropertyName()
                        //println " foundControllerMatch ${returnCtrl}"
                    }
                }

                return returnCtrl
            }

            action = {

                def foundActionMatch = false
                def returnAction = params?._action
                def returnCtrl = params._ctrl

                grailsApplication.controllerClasses.each { GrailsClass c ->
                    def l_className = c.name.toLowerCase()

                    // find the class
                    if (params._ctrl?.equalsIgnoreCase(l_className) && foundActionMatch == false) {

                        returnCtrl = c.name

                        c.URIs.each { _uri ->

                            if (foundActionMatch == false) {
                                def uri = _uri

                                //println "u-> $uri"

                                def uri_action
                                uri_action = uri.split('/')[2]

                                //println "uri_action-> $uri_action"
                                if (uri_action?.trim()?.equalsIgnoreCase(params._action.trim())) {
                                    foundActionMatch = true
                                    returnAction = uri_action
                                }
                            }
                        }
                    }
                }

                return returnAction

            }

        }
    }
}

下面是我如何基于

想想看，你不能在使用URL之前将其转换成小写吗？或者你不能控制代码中的URL？这就是问题所在！基本上问题是：如何在Grails中使用UrlMapping.groovy文件或其他文件来实现这一点。不，这会给出：

无法调用方法toLowerCase（）在空对象上

。你是说你不知道如何处理一个空的动作？我没说这是一个无脑的动作
