twilio教程问题

Question

我跟着教程https://www.twilio.com/docs/quickstart/java/twiml/record-caller-leave-message，我被卡在录音。 twilio日志显示“使用404的问题访问/处理键”。我设置了localtunnel，并且我配置了我的号码以指向http://43v8.localtunnel.com/myapp/twilio网址。问候的作品，我只有在拨号盘上选择1或2时遇到麻烦。我将不胜感激任何帮助。

TwilioHandleRecordingServlet：

package com.twilio; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import java.io.IOException; 
import java.util.HashMap; 

import com.twilio.sdk.verbs.TwiMLResponse; 
import com.twilio.sdk.verbs.TwiMLException; 
import com.twilio.sdk.verbs.Say; 
import com.twilio.sdk.verbs.Play; 
import com.twilio.sdk.verbs.Dial; 

public class TwilioHandleRecordingServlet extends HttpServlet { 

    public void service(HttpServletRequest request, HttpServletResponse response) throws IOException { 

     String recordingUrl = request.getParameter("RecordingUrl"); 
     TwiMLResponse twiml = new TwiMLResponse(); 
     if (recordingUrl != null) { 
      try { 
       twiml.append(new Say("Thanks for howling... take a listen to what you howled.")); 
       twiml.append(new Play(recordingUrl)); 
       twiml.append(new Say("Goodbye")); 
      } catch (TwiMLException e) { 
       e.printStackTrace(); 
      } 
     } else { 
      response.sendRedirect("/twiml"); 
      return; 
     } 

     response.setContentType("application/xml"); 
     response.getWriter().print(twiml.toXML()); 
    } 
}
