import java.net.URL;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;
public class ReadUrl1 {
public static void main(String arg[]) {
String str;
try {
URL url = new URL("http://www.sohu.com/");
InputStream is = url.openStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
while((str = br.readLine()) != null)
System.out.println(str);
br.close();
} catch(IOException e) {
System.out.println(e);
}
}
}
另一种方法：
import java.net.URL;
import java.net.URLConnection;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;
public class ReadUrl2 {
public static void main(String arg[]) {
String str;
try {
URL url = new URL("http://www.sohu.com/");
URLConnection uc = url.openConnection();
InputStream is = uc.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
while((str = br.readLine()) != null)
System.out.println(str);
br.close();
} catch(IOException e) {
System.out.println(e);
}
}
}
还可以设置代理：
import java.net.URL;
import java.net.URLConnection;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;
import java.util.Properties;
public class ReadUrl3 {
public static void main(String arg[]) {
String str;
Properties props = System.getProperties();
props.setProperty("proxySet","true");
props.setProperty("proxyPort","8080");
props.setProperty("proxyHost","proxy");
try {
URL url = new URL("http://www.sohu.com/");
URLConnection uc = url.openConnection();
InputStream is = uc.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
while((str = br.readLine()) != null)
System.out.println(str);
br.close();
} catch(IOException e) {
System.out.println(e);
}
}
}
