我想下载网页内容，但它不能正常工作

Question

我想下载一个网站并将内容作为字符串显示在日志中，但首先应用程序需要几个小时才能加载，如果加载，我就不会获得该网站的源代码。

public class MainActivity extends AppCompatActivity {


    public class DownloadTask extends AsyncTask<String, Void, String> {


        @Override
        protected String doInBackground(String... urls) {

            String result = "";
            URL url;
            HttpURLConnection urlConnection = null;

            try {

                url = new URL(urls[0]);

                urlConnection = (HttpURLConnection)url.openConnection();

                InputStream in = urlConnection.getInputStream();

                InputStreamReader reader = new InputStreamReader(in);

                int data = reader.read();

                while (data!= -1) {

                    char current = (char) data;

                    result += current;

                    data = reader.read();

                }

                return result;

            }
            catch (Exception e){

                e.printStackTrace();

                return "Failed";

            }


        }
    }



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        DownloadTask task = new DownloadTask();
        String result = null;

        try {

            result = task.execute("http://www.kicker.de/").get();


        } catch (InterruptedException e) {

            e.printStackTrace();

        } catch (ExecutionException e) {

            e.printStackTrace();

        }

        Log.i("Contents of URL", result);


    }


}

您应该使用BufferedReader来获取从InputStreamReader
