php facebook api发布在facebook wall publish_actions上

Question

我们开发了一个购物网站，我们使用Facebook登录，当客户购买时，我们已经将产品发布在他们的墙上。为了执行此操作，我使用xxx@test.com在developer.facebook.com中创建了一个应用程序。

如果我使用xxx@test.com并登录我的网站并购买产品它正在发布到Facebook墙但是如果我使用不同的帐户获取例外

user not authorized application 

我开始谷歌搜索，最后我提交了publish_actions审核权限

这是否是在fb墙上发布的唯一方式？为什么单独发布xxx@test.com？

以下是我使用的代码

public function postFbWall($customer_name) {

    if(!isset($this->fbconnect)) {
            require_once(DIR_SYSTEM . 'vendor/facebook-sdk/facebook.php');
            $this->fbconnect = new Facebook(array(
                'appId'  => $this->config->get('fbconnect_apikey'),
                'secret' => $this->config->get('fbconnect_apisecret'),
                "cookie"=>true,
            ));
            $_SERVER_CLEANED = $_SERVER;
            $_SERVER = $this->clean_decode($_SERVER);
    }
    $fbuser = $this->fbconnect->getUser();
    if($fbuser){
        try {
            $fbuser_profile = $this->fbconnect->api("/$fbuser");
            $access_token = $this->fbconnect->getAccessToken();
            $message = "First three users who registers through this links will get 5% of the product price as reward points";
            $attributes = array(
                'name' => $customer_name,
                'caption' => HTTP_SERVER,
                'access_token' => $access_token,
                'message' => 'message goes here',
                'link' => 'link',
                'description' => 'description goes here',
                            );
            $ch = curl_init();
            $purl = "https://graph.facebook.com/".$fbuser."/feed";
            $mattr = "";
            foreach($attributes as $key=>$value):
                $mattr .= $key."=".$value."&";
            endforeach;
            curl_setopt($ch,CURLOPT_URL,$purl);
            curl_setopt($ch,CURLOPT_POST,count($attributes));
            curl_setopt($ch,CURLOPT_POSTFIELDS,$mattr);
            curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
            curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
            curl_setopt($ch,CURLOPT_VERBOSE ,true);
            $res = curl_exec($ch);
            curl_close($ch);
            $resultobj = json_decode($res);
            if(isset($resultobj->id)) { $res =true;} else {$res=false;}
        } catch (FacebookApiException $e) {
            error_log($e);
            $fbuser = null;
        }
    }
}
