php 与java安卓客户端的查询交互

PHP 服务器端：

    function getids()
    {
        $this->output->set_header('Content-Type: application/json; charset=utf-8');
        $jsonstr = '';
        $pname = $pcallid = $pworkid = '';
 
        if (isset($_GET['name'])) {
            $pname = $_GET['name'];
        }
 
        if (isset($_GET['callid'])) {
            $pcallid = $_GET['callid'];
        }
 
        if (isset($_GET['workid'])) {
            $pworkid = $_GET['workid'];
        }
 
        $this->load->model('wireid_model');
 
        $this->wireid_model->insertonly($pname, $pcallid);
 
        if ($pname == '' && $pcallid == '' && $pworkid == '') {
            die();
        } else {
            $sqlstr = 'select * from twireid where 1=1 ';
            if ($pname != '') {
                $sqlstr = $sqlstr . " and GNAME='{$pname}' ";
            } else
                if ($pcallid != '') {
                    $sqlstr = $sqlstr . " and GOLDCALLID='{$pcallid}' ";
                } else
                    if ($pworkid != '') {
                        $sqlstr = $sqlstr . " and GCARDID='{$pworkid}' ";
                    }
            $getdata = $this->wireid_model->getsql($sqlstr);
            //  JSON_FORCE_OBJECT  防止出现 []
            $jsonstr = json_encode($getdata->result_array(), JSON_FORCE_OBJECT);
            echo $jsonstr;
        }
    }

　　java 安卓端：

	doAskTask = new Runnable() {
			@Override
			public void run() {
				// TODO
				// 在这里进行 http request.网络请求相关操作
				ggname = etname.getText().toString();
				ggworkid = etworkid.getText().toString();
				ggcallid = etcallid.getText().toString();
 
				String baseurl = ConfidDatas.askbaseurl;
				String askstr = "name=" + ggname + "&callid=" + ggcallid
						+ "&workid=" + ggworkid;
				String result = null;
 
				HttpGet httpGet = new HttpGet(baseurl + askstr);
				// 第二步，使用execute方法发送HTTP GET请求，并返回HttpResponse对象
				HttpResponse httpResponse = null;
 
				try {
					httpResponse = new DefaultHttpClient().execute(httpGet);
				} catch (ClientProtocolException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
 
				Message msg = new Message();
				Bundle data = new Bundle();
 
				if (httpResponse.getStatusLine().getStatusCode() == 200) {
					// 第三步，使用getEntity方法活得返回结果
					try {
						result = EntityUtils.toString(httpResponse.getEntity());
						data.putString("value", result);
						data.putString("result", "isok");
						msg.setData(data);
						handler.sendMessage(msg);
					} catch (ParseException e) {
						// e.printStackTrace();
					} catch (IOException e) {
						// e.printStackTrace();
					}
				} else { // 错误
					data.putString("value", "");
					data.putString("result", "iserr");
					msg.setData(data);
					handler.sendMessage(msg);
				}
			}
