HttpUrlConnection 使用

package com.longtop;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;

import sun.net.www.protocol.http.HttpURLConnection;
//注意: 这里的HttpURLConnection 类所属的包是sun.net.www.protocol.http
public class HTTPtest {

	public static void main(String[] args) {

		try {
			URL url = new URL("http://www.baidu.com");
			HttpURLConnection connection = (HttpURLConnection) url.openConnection();
			connection.getContent();
			BufferedReader reader = new BufferedReader(new InputStreamReader(
					connection.getInputStream(),"GBK"));
			String lines = null;
			while ((lines = reader.readLine()) != null) {
				System.out.println(lines);
			}
			reader.close();
			// 断开连接
			connection.disconnect();

		} catch (MalformedURLException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}

	}

}
