Q1: java中如何根据一个网址获得该网页的源代码？
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("", "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);
}
}
