Java 从网页抽取数据 存入数据库

台风的编号和名称直接在源码中有，但时间和地理位置我只能跟踪到
function totf(tfbh){
locationhref( "Typhoonaspxid="+tfbh);
}
数据需要从aspx中拿到的，应该是存放到数据库的，页面上是拿不到的
我认为可以通过循环模拟发送请求Typhoonaspxid="+XXX，然后通过解析response包的方式可以获得详细的信息
下面一个页面是讲模拟发送请求的

希望对你有帮助
我写了一段获得一组数据的代码
//get Typhoon content by param
public static String getTyphoon(String param) {
URL url = null;
try {
url = new URL(param);
} catch (MalformedURLException e) {
eprintStackTrace();
}
HttpURLConnection connection = null;
InputStream is = null;
try {
connection = (HttpURLConnection) urlopenConnection();
is = connectiongetInputStream();
} catch (IOException e) {
eprintStackTrace();
}
BufferedInputStream bis = new BufferedInputStream(is);

int len = 0;
byte[] buf_all = new byte[0];
try {
while (true) {
byte[] buf1 = new byte[4096];
byte[] buf2 = buf_all;
len = bisread(buf1);
if(len <= 0){
break;
}
buf_all = new byte[len+buf2length];
Systemarraycopy(buf2, 0, buf_all, 0, buf2length);
Systemarraycopy(buf1, 0, buf_all, buf2length, len);
}
} catch (IOException e) {
eprintStackTrace();
}
String content = null;
try {
content = new String(buf_all, "utf-8");
} catch (UnsupportedEncodingException e) {
eprintStackTrace();
}
int startIndex = contentindexOf("var ary0=")+9;
content = contentsubstring(startIndex);
int endIndex = contentindexOf("var aryyb0=");
content = contentsubstring(0, endIndex);
return content;
}
得到的结果是这样的：

再下去字符串的拆分实在是太复杂了，不想写了
使用时只要参数为http://wwwwztf121com/Typhoonaspxid=
id后是台风的代码号，写一个循环就可以了
