例如,在插入userId之后,我有这个方法打开灯：

@PUT
@Path("/lampon")
@Produces({"application/json","text/plain"})
@Consumes("multipart/form-data")
public boolean turnOnLamp(@FormParam("userId") String userId) throws Exception
{
    boolean response = new LampManager().turnOnLamp(userId);
    return response;
}

在我的客户端应用程序中,我这样做,它的工作原理：

String webPage = "http://localhost:8080/BliveServices/webresources/services.actuators/lampon";
 
    URL urlToRequest = new URL(webPage);
 
    //Authentication
 
    urlConnection = (HttpURLConnection) urlToRequest.openConnection();
    urlConnection.setReadTimeout(10000);
    urlConnection.setConnectTimeout(15000);
    urlConnection.setRequestMethod("PUT");
    urlConnection.setRequestProperty("Authorization",basicAuth);
    urlConnection.setRequestProperty("Content-type","multipart/form-data");
    urlConnection.setRequestProperty("Accept","application/json");
    urlConnection.setDoOutput(true);
    urlConnection.setDoInput(true);
 
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("userId","2"));
 
    (...)

但是如何通过浏览器发送userId呢？

另一件事,我在构建项目时收到此消息：

SEVERE: Resource methods utilizing @FormParam and consuming "multipart/form-data" are no longer supported. See @FormDataParam.

谢谢
