CodeIgniter更新查询执行两次

我正在使用CodeIgniter 2.2.

每次访问页面时,我都必须使用+1更新数据库.代码有效,但每次增加+2.

示例:如果total views=2,单击页面total views应该是3,但数据库中的值是4.

我确信我add_one_to_view_image只在控制器中调用一次模型.

调节器

   function view(){

    $view_id =  $this->uri->segment(3);

    if($view_id){
        $this->property->add_one_to_view_image($view_id);
        $prop['prop_detail'] = $this->property->get_single_property_for_view($view_id);
        $prop['prop_imgs'] = $this->property->get_single_property_images($view_id);
        $prop['amenities'] = $this->property->get_single_property_amenities($view_id);
        $prop['latest'] =  $this->home->get_latest_properties();

        $size = sizeof($prop['latest']);
        for($k=0; $k< $size; $k++){
        $Image_name = $this->property->get_property_first_image($prop['latest'][$k]->property_id);
            if($Image_name){
            $prop['latest'][$k]->image=$Image_name[0]->name;
            }else {
                $prop['latest'][$k]->image="";
            }
        }


    $this->load->view('property_view', $prop); 
    }

HttpsURLconnection发布并获取Android

我正在开发一个简单的应用程序,它使用https协议从服务器发布和获取数据.我在互联网上搜索但是资源很少,我尝试了大部分资源但是无法成功完成.

我尝试使用HttpClient它是成功的,但我想用HttpsURLconnection来做

我是否需要从设备中获取公共RSA密钥,如果是这样,我该怎么做呢.

有人能告诉我如何才能实现这一目标httpsURLconnection.
