java网页数据抓取

对于加密的网站还没去研究，不知道能不能抓取，现在只是对一些没有加密的网站进行网页数据抓取。刚刚开始写的时候以为很多网站都能抓取，但是发现很多都加密了，本来以为一些地址可以通过网页数据检测工具测出他的数据变化，但是只能监测到一些通过js显示的数据，依然不能抓取到加密的网站。嗨，这个问题以后再说吧。

我抓取的网站是手机号查询和身份证查询的网站。http://qq.ip138.com/idsearch/index.asp这个是查询身份证的网站，源地址是这个，但当你输入自己的身份证是地址就会变成http://qq.ip138.com/idsearch/index.asp?action=idcard&userid=你输入的省份证&B1=%B2%E9+%D1%AF根据这个变化就可以抓取到输入特定身份证的网页源代码，再通过解析读取到需要的数据。下面是代码：

 

import java.net.* ;
import java.io.* ;
import java.util.regex.* ;
publicclass Capture{
publicstaticvoid main(String args[])throws Exception{
System.out.println("*************************手机号查询************************") ;
System.out.println("我的位置是：" + new GrabMobile().grabMobileLocation("15023141745")) ;
System.out.println("手机卡类型是：" + new GrabMobile().grabMobileType("15023141745")) ;
System.out.println("我的邮编是：" + new GrabMobile().grabMobilePost("15023141745")) ;
System.out.println("*************************身份证查询************************") ;
System.out.println("我的性别是：" + new GrabIdentity().grabIdentitySex("362203199208243575")) ;
System.out.println("我的生日是：" + new GrabIdentity().grabIdentityBirth("362203199208243575")) ;
System.out.println("我的家乡是：" + new GrabIdentity().grabIdentityHome("362203199208243575")) ;
