java Grails：集成测试Ajax请求xhr

Question

如何在Grails中为控制器设置ajax请求测试

我试过了

    def homeController = new HomeController()

    homeController.request.contentType = "text/json"
    homeController.request.content = '{"event_id":2}'.getBytes()
    homeController.request.xhr = true //error: can't be set

    homeController.landingPage()

在我的“登陆页面”行动中

Controller
...
...
 if(params.event_id){
     //set values of the "event" object
 }

 if (request.xhr) {

       def result = [eventTile: event.getAt(0).title, eventId: event.getAt(0).id]

            render result as JSON
            return
        }
...
...

我无法找到一种方法，在没有正常指定的情况下访问params字段

 homeController.params.event_id = 2

那么，如何设置Grails集成测试来将xhr设置为true，从而从控制器返回JSON呢
