Java中进行url请求（简单示例）

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

public class URLTest {
public static void main(String[] args){
try {
URL url = new URL("http://www.baidu.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.connect();

InputStream is = conn.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));

String line = "";
while((line = br.readLine()) != null){
System.out.println("readLine = " + line);
}

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

}
}
