I really want to contribute to it. In China, 10,000,000 people use alipay payment gateway every day. I'm trying to integrate into NopCommerce1.20.
So far I'm almost there, but I got two problems, I hope stuff here can give me some hints.
I follow the steps below:
Step1: I add a new payment gateway in Administration control panel
this new payment method id is 21
Step2: configue the payment method like this:
Configuration template path: Payment\Alipay\ConfigurePaymentMethod.ascx
User template path: ~\Templates\Payment\Alipay\PaymentModule.ascx
Class name: NopSolutions.NopCommerce.Payment.Methods.Alipay.AlipayPaymentProcessor, Nop.Payment.Alipay
Step3: Payment\Alipay\ConfigurePaymentMethod.ascx
Step4: ~\Templates\Payment\Alipay\PaymentModule.ascx
Step5: Set the AlPpayPaymentModule.Message as
English//AliPayPaymentModule.Message//You will be redirected to Alipay site to complete the order.
Step6: NopSolutions.NopCommerce.Payment.Methods.Alipay.AlipayPaymentProcessor, Nop.Payment.Alipay

document structure:
after this preparation, I tried to debug and I was very confident that I almost done this. but- -
choose payment gateway-->alipay
click next
click next
click confirm to enter debug mode, i set up break point here.
Begin to debug
first problem:
payment info: all fields: Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized.
and I continue to debug, when the process reached
IPaymentMethod iPaymentMethod = Activator.CreateInstance(Type.GetType(paymentMethod.ClassName)) as IPaymentMethod;
another problem occured and at this time, paymentMethod.ClassName = "NopSolutions.NopCommerce.Payment.Methods.Alipay.AlipayPaymentProcessor, Nop.Payment.Alipay".
program breaks and the error message is: Value cannot be null. Parameter name: type, which means Activator can not create an instance of class(NopSolutions.NopCommerce.Payment.Methods.Alipay.AlipayPaymentProcessor, Nop.Payment.Alipay), why???
I'm wondering why this happened.
Anyone got a clue?
Many thanks in advance.
As soon as I finish this payment gateway, I will put it on the extension section of this website.
