Nopcommerce - 自定义支付方式的 PostProcessPayment 不重定向到支付网关 URL

Question

I am developing a custom payment method plugin for a Nopcommerce site. This is the the payment processor class code:

public class CODBookingPaymentProcessor : BasePlugin, IPaymentMethod
{
    private IShoppingCartService _shoppingCartService;
    private IOrderService _orderService;
    private IHttpContextAccessor _httpContextAccessor;

    #region Ctor
    public CODBookingPaymentProcessor(IShoppingCartService shoppingCartService,
        IOrderService orderService, IHttpContextAccessor httpContextAccessor)
    {
        this._shoppingCartService = shoppingCartService;
        this._orderService = orderService;
        this._httpContextAccessor = httpContextAccessor;
    }
    #endregion

    ~~~~~~~~~~~~~~~~ SOME CODE ~~~~~~~~~~~~~~~~~~~~~
public void PostProcessPayment(PostProcessPaymentRequest postProcessPaymentRequest)
    {
          // some code
          string url = protocol + host + "/" + "PaymentCODBooking/ProcessInternetPayment";

        _httpContextAccessor.HttpContext.Response.Redirect(url);
    }

The breakpoint is coming at last line and url is forming correctly. But the page is not redirecting to the url when CONFIRM button is clicked on Checkout page. It just stays on the page or sometimes empties the cart. It means order is being created without going to payment gateway.

UPDATE

The redirect is also not working in ConfirmOrder action of CheckoutController .

if (_webHelper.IsRequestBeingRedirected || _webHelper.IsPostBeingDone)
{
    //redirection or POST has been done in PostProcessPayment
    //return Content("Redirected");

    return Redirect("http://localhost:15536/PaymentCODBooking/ProcessInternetPayment");
}

Answer 1

The redirect has to be an action result. For example in controller's action we write like this:

return Redirect("http://www.google.com");

Without the return keyword it would not redirect.

To redirect from the controller of a plugin check out the similar implementation in the \Plugins\Nop.Plugin.Payments.PayPalStandard\Controllers\PaymentPayPalStandardController.cs class of the PayPalStandard plugin that comes out of the box

Answer 2

If you are trying to develop a plugin, it's so much better to not change the nopCommerce source code. You can perform the redirection in the plugin itself, don't change the ConfirmOrder action of CheckoutController . Change your code to this:

public void PostProcessPayment(PostProcessPaymentRequest postProcessPaymentRequest)
{
      // some code
      string url = protocol + host + "/" + "PaymentCODBooking/ProcessInternetPayment";

    _httpContextAccessor.HttpContext.Response.Redirect(url);
    return;
}

you can find these lines in ConfirmOrder action. The application will rich here after the PostProcessPayment . The redirection performs here:

if (_webHelper.IsRequestBeingRedirected || _webHelper.IsPostBeingDone)
{
    //redirection or POST has been done in PostProcessPayment
    return Content("Redirected");
}

Thank you everyone for help. Your answers gave me some hint and find the issue. The issue was that I forgot to set public PaymentMethodType PaymentMethodType => PaymentMethodType.Redirection; . It was set to Standard which caused the issue.

Answer 4

Changes PaymentMethodType to PaymentMethodType.Redirection It will work
