如何使用 Jersey 读取 RESTful 服务的 POST 参数? [英] How do I read POST parameters for a RESTful service using Jersey?

问题描述

我没有使用 JSON 或类似的东西.我有一个简单的表单来上传文件，我想读取表单的参数.下面的代码没有按预期工作.它不会显示任何参数.

I am not using JSON or anything like that. I have a simple form to upload a file and I want to read the parameters of the form. The code below is not working as expected. It will not show any parameters.

@POST
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
@Path("{appNum}/{docId}/file")
public Response uploadDocFile(
        @PathParam("appNum") String appNum,
        @PathParam("docId") String docId,
        @Context HttpServletRequest req)
{

    try {

        log.info("POST Parameters:");

        Enumeration e = req.getParameterNames();

        while(e.hasMoreElements())
        {
            Object key = e.nextElement();
            log.info("Key: " + key);
            log.info("Val: " + req.getParameter(key.toString()));
        }


    }  catch (Exception e) {
        e.printStackTrace();
        return Response.status(Status.INTERNAL_SERVER_ERROR).entity(new StatusResponse(e)).build();
    }

    return Response.ok().build();
}

推荐答案

仅供参考，您需要使用@FormParam.还要确保 INPUT HTML 类型使用 name= 而不是 id=.

FYI, You need to use @FormParam. Also make sure INPUT HTML types are using name= not id=.
