Java extracts data from web pages and stores it in the database.
Function totf (tfbh) (
location.href( "Typhoon.aspx？ id = "+tfbh)；
}
You need to get data from aspx. The data should be stored in the database, but it can't be obtained on the page.
I think we can send the request Typhoon.aspx through loop simulation? Id="+XXX ",and then parse the response package to get detailed information.
The next page is about analog sending requests.

I hope it helps you.
I wrote a piece of code to get a set of data.
//Get typhoon content through parameters.
Common static string gettyphoon (stringparam) (
URL url = null
Try {
Url = new URL (param);
} catch(malformedurexception e){
e . printstacktrace()；
}
HttpURLConnection connection = null
InputStream is = null.
Try {
connection =(http urlconnection)URL . open connection()；
is = connection . getinputstream()；
} catch (IOException e) {
e . printstacktrace()；
}
BufferedInputStream bis = new BufferedInputStream(is)；
int len = 0；
Byte[] buf_all = new byte [0];
Try {
while (true) {
Byte[] buf 1 = new byte [4096];
byte[]buf 2 = buf _ all；
len = bis . read(buf 1)；
if(len & lt； = 0){
Break;
}
Buf_all = new byte [len+buf2.length];
System.arraycopy(buf2，0，buf_all，0，buf 2 . length)；
System.arraycopy(buf 1，0，buf_all，buf2.length，len)；
}
} catch (IOException e) {
e . printstacktrace()；
}
String content = null
Try {
content = new String(buf_all，“utf-8”)；
} catch(UnsupportedEncodingException e){
e . printstacktrace()；
}
int startIndex = content . index of(" var ary 0 = ")+9；
content = content . substring(startIndex)；
int end index = content . index of(" var aryb 0 = ")；
content = content.substring(0，end index)；
Return content;
}
The result is this:

Disassembling strings is too complicated, so I don't want to write.
As long as the parameter is /Typhoon.aspx? id=
After the id is the code name of the typhoon, just write a cycle.
