试图读取网站的内容但是当打印到logcat时，只显示前5行代码

Question

公共类MainActivity扩展了AppCompatActivity {

我在哪里设置了url和HttpUrlConnection，允许程序读取网址的内容。

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 null;
    }
}

@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.historyplace.com/specials/").get();
        Log.i("Contents of URL", result);
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    }
}

}

我相信我的代码写得正确，因为logCat会显示几行代码。不幸的是它没有显示所有内容。我试图首先检索所有代码，以便我可以使用正则表达式为教育学校项目提取某些图片和名称。
