These are the parameters that are required to create an order on the ping++ platform

The following are the parameters for the successful order creation and the successful callback of the ping++ platform

Paid: Payment status, default to False
refunded: refund status, default to False
Time_paid: Payment time
time_refunded: Refund Time
Charge_ No: Returned charge number
Transaction_no: Transaction number

Steps:

1. Create a local order record

def Create_order

 #获取参数  
 #判断参数合法性 
 
 order = order.new
 #保存订单信息, note the length of subject and body
 #生成订单号并保存
 order_no = (Time.now.to_ formatted_s (: Number)). to_s
 6.times{order_no<<rand. to_s}
 order.order_no = Order_no

 #获取ip并保存
 order.client_ip = request.remote_ip
 
 if order.save
  #返回成功信息
 else
  render_failure ( Order.errors.messages.first[1][0])
 End
 

2. Implementation of payment

Now create a record on the ping++ platform
1. Create a new method in the Order.rb file

 def pay_url
  #获取api_key以及app_id
  pingpp.api_key = pingplusplus.get_ping_settings["Ping_api_key"]
  app_id = pingplusplus.get_ping_settings["ping_app_id"]
  #不同支付渠道的回调地址 case
  Self.channel when
    "Alipay"
    Extra = {
   } when
    ' WX '
    extra = {
   } 
   end
  #ping + + platform Create a new order
  begin
   charge = PINGPP:: Charge.create (
     : Order_no => self.order_no,
     : App  => {: id => app_id},
     : Channel => Self.channel,
     : Amount => Self.amount.round (2) * 100.to_i,
     : Client_ip =>, Self.client_ip,
     : Currency => "CNY",
     : Subject => self.subject[0..31],
     : Body  => self.body[0..127],
     extra  => extra
     )
   
   Return charge
  Rescue pingpp::P ingpperror => error
    logger.error ' ping++ platform Create order failed '
    Logger.error Error.http_body return
    false
  end
 

2. Call the Pay_url method to create the order, return to the client charge object, the client takes charge object to ping++ platform to pay

 def confirm_and_payment
  order_no = params[:order_no]
  channel = Params[:channel]
  if Order_no.blank? | | Channel.blank?
   Render_failure ("parameter is incomplete!") ") and return-order
 
  = Order.where (order_no:order_no).
    Render_failure ("The order does not exist!") ") and return
  end

  charge = Order.pay_url
  if charge = = False
   render_failure (" Order payment failed! ") ") and return
  else
   order.update_attribute (: Charge_no, (Json.parse charge.to_s) [' ID '])
   render (: JSON = > Charge)
  end
 

Asynchronous notification Update Payment results

 def notify status = #判断请求是否有ping + + signature information if request.headers[' X-pingplusplus-signature '].blank? Status = 401 Logger.debug ' "to whom": = = = = = Payment CALLBACK Request SOURCE Error!!!!! ' Return end #获取签名信息 Raw_data = Request.body.read if request.headers[' x-pingplusplus-signature '].is_a? (Array) signature = request.headers[' x-pingplusplus-signature '][0].to_s else signature = request.headers[' X-PINGPL
  Usplus-signature '].to_s End # get "webhooks verify ping++ public key"pub_key_path = "#{rails.root}/config/rsa_public_key.pem" If Verify_signature (Raw_data, Signature, Pub_key_path) #处理接收的结果 event = Json.parse (raw_data) #付款成功 if EV  ent["type"] = = ' charge.succeeded ' # Developer adds the processing code for the payment asynchronous notification here Order_no = event[' data ' [' object '] [' order_no '] order
     = Order.where (order_no:order_no). Order_from = Order.status if order.present? #更新字段 order.paid = event[' data '] [' object '] [' paid '] if order.save status = 5 Else status =
     00End Else Logger.debug ' database does not have this record! ' End #退款成功 elsif event[' type '] = = ' refund.succeeded ' # Developer adds the processing code for the refund asynchronous notification here Order_no = event[' data '
     [' object '] [' order_no '] order = Order.where (order_no:order_no).
     #更新字段 order.time_refunded = time.at (event[' data '] [' object '] [' time_succeed ']) if order.save status = 200 else status = End Else Logger.debug ' database does not have this record! ' End else Logger.debug ' payment callback returns an unknown operation! ' End else Logger.debug ' payment callback request source Error!
 ' Status = 403 end render:nothing => true: the status => status end
