package test; import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.URL; public class HttpTest { private String u; private String encoding; public static void main(String[] args) throws Exception { HttpTest client = new HttpTest("http://www.baidu.com/", "UTF-8"); client.run(); } public HttpTest(String u, String encoding) { this.u = u; this.encoding = encoding; } public void run() throws Exception { URL url = new URL(u);// 根据链接(字符串格式),生成一个URL对象 HttpURLConnection urlConnection = (HttpURLConnection) url .openConnection();// 打开URL BufferedReader reader = new BufferedReader(new InputStreamReader( urlConnection.getInputStream(), encoding));// 得到输入流,即获得了网页的内容 String line; // 读取输入流的数据,并显示 while ((line = reader.readLine()) != null) { System.out.println(line); } } }
