将项目加入你的解决方案并引用。

后台C#代码：

/// <summary>
/// H5支付
/// </summary>
/// <param name="model"></param>
/// <param name="configPath"></param>
/// <returns></returns>
public static string Alipay()
{
string OrderNumber = "alipay" + DateTime.Now.ToString("yyyyMMddHHmmss");
string app_id = "你的app_id";
string merchant_private_key = "你的应用私钥";
string alipay_public_key = "你的支付宝公钥";
string timeout_express = "30m";//订单有效时间（分钟）
string postUrl = "https://openapi.alipay.com/gateway.do";
string sign_type = "RSA2";//加签方式有两种RSA和RSA2 我这里使用的RSA2（支付宝推荐的）
string version = "1.0";//固定值不用改
string format = "json";//固定值
string Amount = "0.01";//订单金额
string method = "alipay.trade.wap.pay";//调用接口固定值不用改
IAopClient client = new DefaultAopClient(postUrl, app_id, merchant_private_key, format, version, sign_type, alipay_public_key, "UTF-8", false);
AlipayTradeWapPayRequest request = new AlipayTradeWapPayRequest();
request.SetNotifyUrl("支付宝后台通知的地址");
request.SetReturnUrl("支付宝前台回跳的地址");
request.BizContent = "{" +
" \"body\":\"对一笔交易的具体描述信息。如果是多种商品，请将商品描述字符串累加传给body。\"," +
" \"subject\":\"商品描述\"," +
" \"out_trade_no\":\"商家唯一订单，填写你项目里生成的唯一订单号\"," +
" \"timeout_express\":\"" + timeout_express + "\"," +
" \"total_amount\":" + Amount + "," +
" \"product_code\":\""+ method + "\"" +
" }";
AlipayTradeWapPayResponse response = client.pageExecute(request);
string form = response.Body.Substring(0, response.Body.IndexOf("<script>"));
return form;
}

前台html代码：

<!DOCTYPE html>

<html>
<head>
<meta name="viewport" content="width=device-width" />
<link href="~/CSS/mui.min.css" rel="stylesheet" />
<script src="~/Scripts/mui.min.js"></script>
<script src="~/Scripts/jquery.min.js"></script>
<title>支付平台</title>
<script type="text/javascript">
jQuery(document).ready(function () {
var alipay = document.getElementById("alipay");
alipay.addEventListener("tap", function () {
var productName = jQuery("#productName").html();
var unitPrice = jQuery("#unitPrice").html();
var quantity = jQuery("#quantity").html();
var amount = jQuery("#amount").html();
