java實現：用URLConnection開啟指定的url，然後用InputStream讀入網頁內容，將讀入的內容存入String中，這個程式網上有很多。import java.io.*;import java.net.*;public class VisitWeb {public String getWeb(String url) {try {StringBuffer txt = new StringBuffer();URL url = new URL(url);URLConnection conn = url.openConnection();conn.setDoOutput(true);InputStream in = conn.getInputStream();InputStreamReader inReader = new InputStreamReader(in);BufferedReader reader = new BufferedReader(inReader);String rdline = "";while((rdline=reader.readLine())!=null) {txt.append(rdline+"\n");}} catch(Exception e) {e.printStackTrace();}return txt.toString();}}
