Question

         URLPing urlPing = new URLPing();
         PingResponse pingResponse = urlPing.ping(URLName);
         if(pingResponse.getResponseCode() == 200){
                response = true;
         }
         else{
                response=false;
         }

这是我目前尝试过的。

Ping URL from JAVA Code

public static boolean pingUrl(final String address) {
 try {
  final URL url = new URL("http://" + address);
  final HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();
  urlConn.setConnectTimeout(1000 * 10); // mTimeout is in seconds
  final long startTime = System.currentTimeMillis();
  urlConn.connect();
  final long endTime = System.currentTimeMillis();
  if (urlConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
   System.out.println("Time (ms) : " + (endTime - startTime));
   System.out.println("Ping to "+address +" was success");
   return true;
  }
 } catch (final MalformedURLException e1) {
  e1.printStackTrace();
 } catch (final IOException e) {
  e.printStackTrace();
 }
 return false;
}
