LINE Pay款流程：
reserve Page(紅科) 發送 reserve API => 取得 payment URL => 轉址到 payment URL => LINE Pay 檢查USER狀態 => 轉回confirm page(紅科), 發送 confirm API => DOWN.
付款需要程式：
reserve API, confirm API:
send request JSON and read return JSON:
C#:
using System.Net;
using System.IO;
public partial class TEST : System.Web.UI.Page

httpWebRequest.Headers.Add("X-LINE-ChannelId", DB.SysConfig.LINEPay.ChannelId);
httpWebRequest.Headers.Add("X-LINE-ChannelSecret", DB.SysConfig.LINEPay.SecretKey);
//加入參數

streamWriter.Write(requestJSON);
streamWriter.Flush();

}
//取得回覆資訊

//解讀回覆資訊
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
