پَرباد چیست؟

آنچه که شما در این مطلب یاد خواهید گرفت:

• طریقه نصب
  
• ایجاد صورتحساب و ارسال کاربر به درگاه پرداخت
• تایید صورتحساب
• مردود کردن صورتحساب قبل از انتقال وجه از مشتری به فروشنده
• برگشت وجه به حساب مشتری پس از تأیید صورتحساب
  
• درگاه مجازی پرداخت (برای تست وب اپلیکیشن، بدون داشتن حساب واقعی در درگاه‌های بانکی)
• تنظیمات
  
• ذخیره سازی اطلاعات پرداخت

طریقه نصب

PM> Install-Package Parbad.MVC5

ایجاد صورتحساب و ارسال کاربر به درگاه پرداخت

در وب سایت‌های MVC می‌توانید به روش زیر عمل کنید

if (result.Status == RequestResultStatus.Success)
{
   // کاربر را به سمت وب سایت درگاه پرداخت هدایت میکند 
   return new RequestActionResult(result);
}
else
{
   return View("Error");
}

تأیید صورتحساب

برگشت وجه به حساب مشتری پس از تأیید صورتحساب

var refundResult = Payment.Refund(new RefundInvoice([Order Number], [Amount]));

درگاه مجازی پرداخت

در نتیجه در هنگام هدایت کاربر به درگاه پرداخت، کاربر به درگاه مجازی هدایت خواهد شد.

1. هاست اشتراکی
2. سرورهای مجازی
3. سرور اختصاصی

نکته ای در مورد سرورهای اختصاصی و حتی گاها VPSها هست اینکه عموما پشتیبانی این‌ها توسط شما تامین می‌شود و  یا باید یک مدیر سرور با حق ماهیانه اختیار کنید یا در صورت بروز مشکل به صورت ساعتی حق حل مشکل را بدهید. بهتر هست این مورد را از قبل توسط میزبان جویا شوید.

1. دیتاسنتر
2. سرور
3. نزدیکی سرور به محل زندگی کاربران هدف
