Installation

Add this line to your application's Gemfile:

gem 'jasl_tenpay'

or development version

gem 'jasl_tenpay', :github => 'jasl/jasl_tenpay'

And then execute:

$ bundle

Usage

Config

JaslTenpay.pid = 'YOUR_PID'
JaslTenpay.key = 'YOUR_KEY'

Generate payment url

e.g:

options = {
  :out_trade_no      => 'YOUR_ORDER_ID',         # 20130801000001
  :subject           => 'YOUR_ORDER_SUBJECCT',   # Fitbit flex
  :body              => 'YOUR_ORDER_DESCRIPTION',# from knewone.com
  :total_fee         => 1,                       # price, unit: cent
  :spbill_create_ip  => request.ip,              # user ip
  :return_url        => 'YOUR_ORDER_RETURN_URL', # http://knewone.com/orders/1/tenpay_callback
  :notify_url        => 'YOUR_ORDER_NOTIFY_URL'  # http://knewone.com/orders/1/tenpay_notify
}

JaslTenpay::Service.create_interactive_mode_url(options)
# => 'https://gw.tenpay.com/gateway/pay.htm?...'

BTW: Wechat payment using the same api, addition needs provide argument :bank_type => 'WX'

You can redirect user to this payment url, and user will see a payment page for his/her order.

read Tenpay integration manual to get more options.

Verify notify

# example in rails
# The notify url MUST be set when generate payment url
# IMPORTANT: Notify may reach earlier than callback
def tenpay_notify
  if JaslTenpay::Notify.verify?(params.except(*request.path_parameters.keys)) && callback_params[:trade_state] == '0'
    # TODO: valid notify, code your business logic here.
  else
    # TODO: invalid, something went wrong, handle it.
  end
  render text: 'success'
end
