Question

因此，我正在尝试向网站发送帖子请求，以便搜索特定内容，例如游戏网站上的游戏。问题是每当我执行帖子时，它似乎只返回主网站的帖子值放入搜索栏，而不是结果页面。我打印出整个日志，但是它非常长，所以我只是把它放在我放置字符串的部分，但它仍然是主页。

public class Search extends Fragment {

/*Fragment Variables*/
private String[] results = new String[]{};
private EditText searchEdit;
private View view;

/*AsyncTask Variables*/
private Document doc;
private String urlString = "http://www.vogella.com";
private String title;
private String gamespotSearchId = "siteSearch";
private List<NameValuePair> list = new ArrayList<NameValuePair>(1);


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.fragment_search, container, false);
    searchEdit = (EditText) view.findViewById(R.id.searchEditText);
    new BackGroundTask().execute();
    return view;
}
class BackGroundTask extends AsyncTask<Void, Void, String> {

    @Override
    protected String doInBackground(Void... params) {
        HttpPost httpPost = new HttpPost("http://www.gamespot.com");
        list.add(new BasicNameValuePair("q", "final fantasy"));
        try {
            httpPost.setEntity(new UrlEncodedFormEntity(list));
            try {
                HttpClient httpClient = new DefaultHttpClient();
                HttpResponse response = httpClient.execute(httpPost);
                // writing response to log
                readStream(response.getEntity().getContent());
            } catch (ClientProtocolException e) {
                // writing exception to log
                e.printStackTrace();

            } catch (IOException e) {
                // writing exception to log
                e.printStackTrace();
            }
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }

        // Making HTTP Request

        return null;
    }

    private void readStream(InputStream inputStream) {
        BufferedReader buf = null;
        try{
            buf = new BufferedReader(new InputStreamReader(inputStream));
            String line = "";
            while((line = buf.readLine())!= null){
                System.out.println(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }finally{
            if(buf != null){
                try{
                    buf.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }


    @Override
    protected void onPostExecute(String result) {
        Log.d("onPostExecute", "just set the text view");
        super.onPostExecute(result);
    }

}

}

Answer 1

我使用Chrome PostMan Rest Client做同样的事情，我得到了相同的结果。

我怀疑Gamespot是否希望人们像这样抓取他们的页面，也许他们会被用户代理标题或类似的东西过滤掉。

看看他们的HTML，无论如何我都不想尝试。

Answer 2

通过Java http post

打印PHP echo消息是有效的

HttpClient client = new DefaultHttpClient();
HttpPost postMethod = new HttpPost("http://192.195.68.83/Upload/index.php");

ArrayList<NameValuePair> arrayList = new ArrayList<NameValuePair>();
arrayList.add(new BasicNameValuePair("cmd", "1"));
arrayList.add(new BasicNameValuePair("comment", "This is comment"));

postMethod.setEntity(new UrlEncodedFormEntity(arrayList));

HttpResponse response = client.execute(postMethod);
HttpEntity httpEntity = response.getEntity();
String state = EntityUtils.toString(httpEntity);
Log.i("chauster",state);

Http Post没有张贴
