在 wordpress 插件中执行 get 请求

你好，我正在修改一个 wordpress 支付网关插件，我想要做的是在每次付款时调用安装在另一台服务器上的 rest api 我从浏览器中这样调用它并且它可以工作 http://xxx。 xxx.xxx.xxx:3000/ ，我使用 wp_remote_request( "http://xxx.xxx.xxx.xxx:3000/", "" );但它没有用。

 // Submit payment and handle response
public function process_payment( $order_id ) {
    global $woocommerce;
    
    // Get this Order's information so that we know
    // who to charge and how much
    $customer_order = new WC_Order( $order_id );
    
    // Are we testing right now or is it a real transaction
    $environment = ( $this->environment == "yes" ) ? 'TRUE' : 'FALSE';

    // Decide which URL to post to
    $environment_url = ( "FALSE" == $environment ) 
                       ? 'https://secure.authorize.net/gateway/transact.dll'
                       : 'https://test.authorize.net/gateway/transact.dll';

    // This is where the fun stuff begins
