我有一个用于将支付网关集成到wordpress woocommerce中的插件。它工作正常，但是当响应来自网关时，我不知道如何在wordpress中获取和显示它。这是插件代码：

    function sb_gtpay_init() {
    if (!class_exists('WC_Payment_Gateway')) {
        return;
    }

    class WC_GTPay extends WC_Payment_Gateway { 

        public function __construct() { 
            global $woocommerce;

            $this->id       = 'gtpay';
            $this -> icon  =  plugins_url( 'GTPay.png' , __FILE__ );
            $this->has_fields   = false;

            $this->method_title     = __( 'GTPay', 'woocommerce' );

            // Load the form fields.
            $this->init_form_fields();

            // Load the settings.
            $this->init_settings();

            // Define user set variables
            $this->title        = $this->settings['title'];
            $this->description  = $this->settings['description'];
            $this->marchant_id  = $this->settings['marchant_id'];   
            $this->hash_key     = $this->settings['hash_key'];  
            $this->thanks_message   = $this->settings['thanks_message'];    
            $this->error_message    = $this->settings['error_message']; 
            $this->feedback_message …
