通过URL获取页面内容

1、

public static void main(String[] args) {
try {
//创建一个URL实例
URL url = new URL("https:/p.php");

try {
//通过URL的openStrean方法获取URL对象所表示的自愿字节输入流
InputStream is = url.openStream();
InputStreamReader isr = new InputStreamReader(is,"utf-8");

//为字符输入流添加缓冲
BufferedReader br = new BufferedReader(isr);
String data = br.readLine();//读取数据

while (data!=null){//循环读取数据
System.out.println(data);//输出数据
data = br.readLine();
}
br.close();
isr.close();
is.close();
} catch (IOException e) {
e.printStackTrace();
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
}

}
