Question

大家好，我需要做的一件事就是...... 点击我做过的任何网址

public class UrlPinger extends AsyncTask<URL, Void, Void> {

        @Override
        protected Void doInBackground(URL... urls) {
            URL url = urls[0];

            try {
                HttpURLConnection urlConnection = (HttpURLConnection) url
                        .openConnection();
                urlConnection.connect();
                System.out.println("thisi si wie URL>>>"+url+"");
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                System.out.println("ERROR "+e.getMessage()+"");
            }

            return null;

        }

上面的类没有给我任何错误但是也没有打到URL我错了什么？并像这样称呼它

UrlPinger pinger = new UrlPinger();
                    pinger.execute(myURL);// this is perfect url copy pase in browser hits

HttpURLConnection connection = null;
    try {
        URL u = new URL("http://www.google.com/");
        connection = (HttpURLConnection) u.openConnection();
        connection.setRequestMethod("HEAD");
        int code = connection.getResponseCode();
        System.out.println("" + code);
        // You can determine on HTTP return code received. 200 is success.
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } finally {
        if (connection != null) {
            connection.disconnect();
        }
    }
