定义和使用 codeigniter 控制器的全局对象

Question

您好，我正在使用 Magento Soap clinet。我正在一个控制器内创建很多功能，这就是为什么我想将 $client 和 $session_id 设置为全局。

这是我的代码-

    <?php

//关闭所有错误报告

      error_reporting(0);

//包括 SOAP 客户端

      require_once APPPATH.'third_party/client/soap_clinet.php';

//API 类

     class Api extends CI_Controller{

//公共变量

     public $variable = "tree";  //working fine

//如下定义$client对象也会产生错误。

      public $client = new SoapClient('http://localhost/mystore/index.php/api/?wsdl');  

      public $session_id;


 public function _construct()
 {
   parent::_construct();
 }


  function index()
 {

 $data['title'] = "SOAP";
 $data['heading'] = "Showing Magento SOAP connectiviy";

  $this->load->view('apiview', $data);  
 }

//我需要此功能的帮助

  function login(){


 try{
        $this->session_id = $this->client->login(
        'fmniloy',
        'abc123'
        );

        echo 'Connection complete: session id ='.$this->session_id;
     }

  catch (SoapFault $fault)
  {
   echo 'Fault Code: '.$fault->faultcode.'<br/>';
   echo 'Fault Reason: '.$fault->faultstring;
  }


  }  //login ends


   function tree()
  {   
   //it's printing global $variable successfully

      echo $this->variable;
  }




  }
  ?>

终于我找到了解决方案。 首先，不可能将对象声明为公共对象。我们可以将 $client 对象和 $session_id 传递给其他函数。解决办法如下。

    <?php

//关闭所有错误报告 错误报告（0）； //包括 SOAP 客户端

      require_once APPPATH.'third_party/client/soap_clinet.php';

//API 类

       class Api extends CI_Controller{

 //public variable
      public $remote_server = "http://localhost/mystore/index.php/api/?wsdl";
      public $username = "fmniloy";
      public $password = "abc123";


         public function _construct()
        {
            parent::_construct();
         }


    function index()
   {

     $data['title'] = "SOAP";
     $data['heading'] = "Showing Magento SOAP connectiviy";

      $this->load->view('apiview', $data);  
    }


       //Login to Server
        function login(){


     //login to Client Serve
      $client = new SoapClient($this->remote_server); 

      try{
      //filled with webservice username and passwd 
         $session_id = $client->login(
         $this->username,
          $this->password
        );

        //echo 'Connection complete: session id ='.  $session_id;

        }

        catch (SoapFault $fault)
       {
           echo 'Fault Code: '.$fault->faultcode.'<br/>';
           echo 'Fault Reason: '.$fault->faultstring;
        }

//将$client对象和$session_id输入到数组中 $soap_vars = array($client, $session_id); //返回值供其他函数使用 返回 $soap_vars;

         }  

//登录结束

          function tree()
          {
           $soap_vars =  $this->login();




           $result = $soap_vars[0]->call($soap_vars[1], 'catalog_category.tree');
          echo '</br></br></br>Catagory Tree: ';
         var_dump($result);

        }




    }
       ?>
