Question

当我使用以下代码向eclipse中的给定网站发出get请求时：

public String getLink(){
    vidLink = "https://www.youtube.com/results?search_query=paradise+city+guns+n+roses+audio+only";
    try {
        URL url = new URL(vidLink);
        HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
        InputStream in = new BufferedInputStream(urlConnection.getInputStream());
        Scanner s = new Scanner(in).useDelimiter("\\A");
        result = s.hasNext() ? s.next() : "";
    }
    catch(Exception e){
        System.out.println("error");

我得到了回应（存储在可变结果中）

<li><div class="yt-lockup yt-lockup-tile yt-lockup-video vve-check clearfix" data-context-item-id="CutFtFcZLrA"

（这是我想要的）

然而，当我使用异步任务在android studio中发出相同的get请求时，使用以下代码：

    public class HttpGetRequest extends AsyncTask<String, Void, String> {
    public static final String REQUEST_METHOD = "GET";
    public static final int READ_TIMEOUT = 15000;
    public static final int CONNECTION_TIMEOUT = 15000;
    String result;
    String inputLine;
    String sname = "hello";
    @Override
    protected String doInBackground(String... params){
        try {
            String stringUrl = "https://www.youtube.com/results?search_query=paradise+city+guns+n+roses+audio+only";
            URL myUrl = new URL(stringUrl);
            HttpURLConnection connection = (HttpURLConnection)
                    myUrl.openConnection();
            connection.setRequestMethod(REQUEST_METHOD);
            connection.setReadTimeout(READ_TIMEOUT);
            connection.setConnectTimeout(CONNECTION_TIMEOUT);
            connection.connect();
            InputStream in = new BufferedInputStream(connection.getInputStream());
            Scanner s = new Scanner(in).useDelimiter("\\A");
            result = s.hasNext() ? s.next() : "";

            linkloc = result.indexOf(testString) + testString.length();
            for(int i = linkloc; result.charAt(i) != ('\"'); i++){
                sname += result.charAt(i) + "";
            }

        }
        catch(IOException e){
            e.printStackTrace();
            sname = "Error";
        }


        return result;
    }

我得到了响应（存储在可变结果中）的内容：＆lt; ！DOCTYPE html＆gt; @ font-fac等....

两个请求之间有什么区别，如何修复android studio响应以获取eclipse中的响应？任何帮助将不胜感激！

与eclipse相比，为什么我使用AsyncTask获得不同的HTML响应？
