自己写的欢迎指正，soap如何调用thinkphp3.2

namespace Home\Controller;

use Think\Controller;

class IndexController extends Controller {

        $host = $_SERVER['HTTP_HOST']; 

        $module = MODULE_NAME; 

        $action = ACTION_NAME;

        $server="";

        $wsdl="";      

        $soaparray=array("location"=>"http://".$host."/".$module."/".$action,"uri"=>$action.".html");

        $server= new \SoapServer(null,$soaparray); 

        $server->setClass(get_class($this)); 

        $server->handle();        


    }  

    public  function Add($a,$b)

   {

      return $a+$b;

   }

   public function testsoap(){
