ASP⽀付（V3⽀付）让更多ASP新⽼项⽬更加⽅便做社交电商。很多asp⽼项⽬⼀直运营的⽐较好，也不愿意去更换技术，今天我⽤我整理的常⽤WeixinDLL组件给⼤家讲解⽀付过程。
准备⼯作：
1、注册服务号（⼀定要认证）、开通⽀付
2、安装⽀付安全证书
此处介绍V3⽀付，⼀共是⽤三个执⾏⽂件代码进⾏讲解！
1、toPay.asp 发起⽀付
2、pay_ok.asp ⽀付成功页
3、notify.asp ⽀付成功过程服务器与我们的服务器通信，将⽀付结果数据推送到我们服务器上
页⾯：toPay.asp

4On Error Resume Next
5Dim notify_url,redirect_url,payapiurl,attach
6 notify_url = "www.domain/pay/notify.asp"'⽀付完成后将在后台发送回调处理信息，由本页⾯接受是否成功⽀付的信息
7 redirect_url = "www.doman/pay/pay_ok.asp"'⽀付完成后，跳转到本页⾯，⽤于展⽰订单⽀付提⽰，本页⾯可以⾃⼰修改
8 payapiurl = "h.weixin.qq/pay/unifiedorder"
9 body = "购买元森美⽔果酵素"'Trim(Request.Form("body")) ' 商品名称
10 total_fee = 0.01*100''Trim(Request.Form("total_fee"))*100 ' 以分为单位，⼊库前需要除以100
11 openid = OpenID 'Trim(Request.Form("openid")) ' "oK1dP1tPcSsh6xog898yXiuGlfaI" //测试openid
12 attach = "OnlinePay___1212"' ⽤于标记，⽅便在notify时进⾏数据库相关操作

15Set Md5Obj = Server.CreateObject("WeixinDLL.Md5Class")
16Set WxObj = Server.CreateObject("WeixinDLL.WeixinClass")
