Implementación en Ruby de pago con WebpayPlus de Transbank.
Esta gema no es de Transbank. Aunque está basada al 100% en la documentación de TransbankDevelopers.
Agregar al Gemfile:
gem 'tbk-soap'Instalar gemas:
$ bundle
Or install it yourself as:
$ gem install tbk-soap
Generador: Falta copiar los archivos de tbk a la carpeta config/tbk
$ rails generate transbank:install
Add this line to your application's Gemfile:
gem 'tbk-soap'Configurar
Transbank::Webpay.configure do |config|
config.wsdl_transaction_url = 'https://webpay3gint.transbank.cl/WSWebpayTransaction/cxf/WSWebpayService?wsdl'
config.wsdl_nullify_url = 'https://webpay3gint.transbank.cl/WSWebpayTransaction/cxf/WSCommerceIntegrationService?wsdl'
config.cert_path = 'config/tbk/597020000541.crt'
config.key_path = 'config/tbk/597020000541.key'
config.server_cert_path = 'config/tbk/tbk.pem'
config.commerce_code = '597020000541'
endPara generar una nueva transacción
class WebpayController < ApplicationController
# ...
# Start a payment
def pay
# Setup the payment
@payment = Transbank::Webpay.init_transaction(SALE_TOTAL, SALE_ID, USER_ID, CONFIRMATION_URL, SUCCESS_URL)
# Redirect the user to Webpay
redirect_to @payment["url"] + "?token_ws=" + @payment["token"]
end
# ...
endConfirmar la transacción
class WebpayController < ApplicationController
# ...
# Confirmation callback executed from Webpay servers
# Aqui depende de cada comercio.
def confirmation
response = Transbank::Webpay.get_transaction_result(params[:token_ws])
response_code = response["responsecode"] || -1
if !Transbank::Webpay.valid_transaction_result?(response_code) || SALE.paid?
# REDIRECT_TO checkout
end
# Execute after 30 seconds
acknowledge_response = Transbank::Webpay.acknowledge_transaction(params[:token_ws])
unless SALE.paid?
SALE.pay! if Transbank::Webpay.valid_acknowledge_result?(acknowledge_response)
@urlredirection = response["urlredirection"]
render "confirmation.html.erb", layout: false # ver abajo
end
end
# ...
endLuego del acknowledge, se debe "redireccionar" a traves del método POST. Si se redirecciona con GET, mostrará "Error de transacción" en el voucher. Para lograrlo, se usa un formulario en html. Transbank también lo utiliza en el flujo.
