[Java] 讀取網頁中的文字 HttpURLConnection 和 URL

import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.net.HttpURLConnection;
import java.net.URL;

以下是在接XML中方便接傳值的方法，首先設定要抓取的網頁位置
URL url = new URL("http://localhost/test.jsp");
用HttpURLConnection 開起
HttpURLConnection huc = (HttpURLConnection)url.openConnection();

InputStreamReader之後在寫使用方式
BufferedReader br = new BufferedReader(new InputStreamReader(huc.getInputStream(), "UTF-8"));

一樣用BufferedReader去讀回來

String str = "";
StringBuffer sb = new StringBuffer();
while(null != ((str=br.readLine()))) {
sb.append(str);
}
br.close();
String xmlResponse = sb.toString();

最後要記的關閉連結
br.close();
huc.disconnect();
