JSP Implementation of the thief Program

I graduated more than half a year...

I used to work hard at school. After graduation, I began to devote myself to the programming world. However, I still have a low length of service and lack of experience. I only knew a month ago that there were thieves.ProgramHaha

How can we implement this? Isn't it possible to access other people's databases? Later, I checked the information and found out that I had read the webpage files of other people, filtered the keywords, and crawled the required information ..... The name is really an image .. Thief Program

Haha, I was suddenly interested a month later. I studied it with JSP and found that the original thief could be so simple .... It's almost just reading files, but it's just changing to remote.

CodeAs follows:
========================================================== ========================================
<% @ Page Language = "Java" pageencoding = "UTF-8" %>
<% @ Page import = "Java. Io. *, java.net. url" %>
<%
URL url = new URL ("http://www.itpub.net"); // create a URL object and instantiate it as a URL to get the address of the web page to be crawled
Bufferedreader reader = new bufferedreader (New inputstreamreader (URL. openstream (), "gb2312"); // create a bufferedreader object and instantiate it as reader. Here, gb2312 is the webpage encoding format to be crawled.
While (reader. Ready ())
{
Out. println (reader. Readline ());
}
Reader. Close ();
%>

The content of the webpage has been captured here. As for what content is needed, I will not describe the specific screening. The specific requirements are implemented.
