Grails：映射到响应代码，无法更改http状态代码

Question

"404" (controller: 'error', action: 'pageNotFound')

Any changes to response.status inside the pageNotFound action is reverted back to 404 before the response is sent to the client. Is it possible to work around this some way? I would like to be able to change it to 410 when I detect that the resource has been deleted or 301 when it's moved permanently.

Answer 1

If that's not working try this in your error controller:

class ErrorController {

    def notFound = {
        redirect( action: 'gone')
      }

    def gone= {
        response.sendError(410, "Gone")
    }
}

Answer 2

尝试通过response.setHeader（）手动设置标题
