Dropwizard ExceptionMapper：验证原始标头字段 [英] Dropwizard ExceptionMapper: Validate original header fields

问题描述

有人知道我如何从请求中获取原始标头字段吗？我想验证，如果客户端将收到html或只是纯文本/文本响应。我可以在exceptionMapper的 toResponse方法中获取此字段吗？

Does anyone know how I can get the original header fields from request? I would like to validate, if client will receive html or just plain/text response. Can I get this fields inside 'toResponse' method of exceptionMapper?

我创建了exceptionMapper，如下所示：

推荐答案

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.core.Context;

@Path("/my")
@Produces(["application/json", "application/hal+json"])
class MyController {

  @Context
  protected HttpServletRequest httpRequest

  @Timed
  @GET
  public Response getOne(){
    httpRequest.getHeaders(); 
    ... //do something with headers
    return Response.ok(new Person(id:1), httpRequest.getContentType());
  }
