支付網關沒有向URL發送請求參數？

Question

這是我自定義支付網關的以下代碼。 當我試圖在檢出頁面下訂單時，它顯示連接到由我創建的服務器異常。當我們檢查螢火蟲中的參數時，它只顯示結帳並且響應失敗。 我嘗試發送請求參數到網關URL但沒有成功。 請告訴我我犯了什麼錯誤？ 在此先感謝..

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://www.qpayindia.com/wwws/Payment/PaymentDetails.aspx'

     $customer_order->add_order_note(__('Authorize.net payment completed.', 'spyr-authorizenet-aim')); 

     // Mark order as Paid 
     $customer_order->payment_complete(); 

     // Empty the cart (Very important step) 
     $woocommerce->cart->empty_cart(); 

     // Redirect to thank you page 
     return array(
      'result' => 'success', 
      'redirect' => $this->get_return_url($customer_order), 
     ); 
    } else { 
     // Transaction was not succesful 
     // Add notice to the cart 
     wc_add_notice($r['Message'], 'error'); 
     // Add note to the order for your reference 
     $customer_order->add_order_note('Error: '. $r['Message']); 
    } 

} 

// Validate fields 
public function validate_fields() { 
    return true; 
}

我想你在這裏混淆了邏輯：

if (is_wp_error($response)) 
    throw new Exception(....); 
else 
{ 
    throw new Exception(....); 
} 

所以你不管扔效應初探的異常，而這樣一來，你永遠也達不到的代碼進一步下跌。一個例外總會打破目前的流程，除非被「try ... catch」所困擾，否則它會突破程序。對於快速測試，請嘗試以下方法（請注意大括號）：

if (is_wp_error($response)) { 
    throw new Exception(__('We are currently experiencing problems trying to connect to this payment gateway. Sorry for the inconvenience.', 'spyr-authorizenet-aim')); 
} else if (empty($response['body'])) { 
    throw new Exception(__('Authorize.net\'s Response was empty.', 'spyr-authorizenet-aim')); 
} 

// Retrieve the body's resopnse if no errors found 
// ...
