2tabactivity...
3 public static String getHttpPost(String actionCode, Map<String, String> map)
throws AppException{

InputStream inputStream = null;

String str = "" ;

String uriAPI = URLs.PATH + actionCode;
        // HttpPost httpRequest =new HttpPost(uriAPI);
        List<NameValuePair> params = new ArrayList<NameValuePair>();        params.add(new BasicNameValuePair("Msisdn", AppContext.getMsisdn()));
//        params.add(new BasicNameValuePair("ActionCode", actionCode));
        for(Map.Entry<String, String> entry : map.entrySet()){
         params.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
        }        try {
            BasicHttpParams httpParameters = new BasicHttpParams();
            HttpConnectionParams.setConnectionTimeout(httpParameters, URLs.TIME_OUT);// 超时时间25秒
            HttpPost httpRequest = new HttpPost(uriAPI);
            HttpClient httpClient = new DefaultHttpClient(httpParameters);            httpRequest.setEntity(new UrlEncodedFormEntity(params, "gbk"));//web端格式是gbk            HttpResponse httpResponse = httpClient.execute(httpRequest);            int statusCode = httpResponse.getStatusLine().getStatusCode();
            if (statusCode == HttpStatus.SC_OK) {             str  = EntityUtils.toString(httpResponse.getEntity());            } else {
                // Log.v("tag", "error resp="+httpResponse);            }        } catch (IOException e) {
            e.printStackTrace();
        }


return str;
