asp.net mvc 接入最新支付宝支付+退款 alipay-sdk-NET-20170615110549
第1步:
https://openhome.alipay.com/developmentDocument.htm
第2步:下载sdk和demo
https://docs.open.alipay.com/270/106291/
https://docs.open.alipay.com/54/103419
第3步:将SDK放到解决方案下并在解决方案下打开下载下来的SDK项目
第4步:新建项目,项目中新建一个类存放支付宝配置相关信息
登录支付宝进入开发者中心
https://openhome.alipay.com/platform/appDaily.htm?tab=info
public class AlipayConfigHelper { //↓↓↓↓↓↓↓↓↓↓请在这里配置您的基本信息↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
//支付宝网关地址 // -----开发环境地址----- //public static string serviceUrl = "https://openfile.alipay.com/chat/multimedia.do"; // -----沙箱地址----- public static string serviceUrl = "https://openapi.alipaydev.com/gateway.do"; // -----线上地址----- //public static string serviceUrl = "https://openapi.alipay.com/gateway.do"; //应用ID,以2088开头由16位纯数字组成的字符串 public static string appId = "2016080500169628"; //开发者私钥,由开发者自己生成 public static string privateKey = @"******"; //支付宝的公钥,由支付宝生成 public static string alipayPublicKey = @"*****";
//服务器异步通知页面路径,需http://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问 //public static string notify_url = "http://" + System.Web.HttpContext.Current.Request.Url.Host + ":" + System.Web.HttpContext.Current.Request.Url.Port + "/College/NotifyUrl"; public static string notify_url = "http://ryan.wicp.net/College/NotifyUrl"; //页面跳转同步通知页面路径,需http://格式的完整路径,不能加?id=123这类自定义参数,必须外网可以正常访问 //public static string return_url = "http://" + System.Web.HttpContext.Current.Request.Url.Host + ":" + System.Web.HttpContext.Current.Request.Url.Port + "/College/ReturnUrl"; public static string return_url = "http://ryan.wicp.net/College/ReturnUrl"; //参数返回格式,只支持json public static string format = "json"; // 调用的接口版本,固定为:1.0 public static string version = "1.0"; // 商户生成签名字符串所使用的签名算法类型,目前支持RSA2和RSA,推荐使用RSA2 public static string signType = "RSA2"; // 字符编码格式 目前支持utf-8 public static string charset = "utf-8"; // false 表示不从文件加载密钥 public static bool keyFromFile = false; //↑↑↑↑↑↑↑↑↑↑请在这里配置您的基本信息↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑ }
第5步:控制器处理
(1)初始化配置文件信息
#region 初始化配置文件信息 private IAopClient GetAlipayClient() { //支付宝网关地址 string serviceUrl = AlipayConfigHelper.serviceUrl; //应用ID,以2088开头由16位纯数字组成的字符串 string appId = AlipayConfigHelper.appId; //商户私钥 string privateKey = AlipayConfigHelper.privateKey; //支付宝的公钥 string alipayPublicKey = AlipayConfigHelper.alipayPublicKey; string format = AlipayConfigHelper.format; string version = AlipayConfigHelper.version; string signType = AlipayConfigHelper.signType; string charset = AlipayConfigHelper.charset; bool keyFromFile = false; IAopClient client = new DefaultAopClient(serviceUrl, appId, privateKey, format, version, signType, alipayPublicKey, charset, keyFromFile); return client; } #endregion
(2)调用SDK生成支付表单
#region 调用SDK生成支付表单 public ActionResult CreatePayForm() { try { IAopClient client = GetAlipayClient(); AlipayTradePagePayRequest request = new AlipayTradePagePayRequest(); //在公共参数中设置回跳和通知地址 request.SetReturnUrl(AlipayConfigHelper.return_url); request.SetNotifyUrl(AlipayConfigHelper.notify_url); var RRR=Request["orderNo"].ToString(); //获取订单信息 DataTable dr = collegeService.GetOrderInfo(RRR).Tables[0]; //方法1: AlipayTradePayModel model = new AlipayTradePayModel(); //填充业务参数 model.Body = "商学院报名"; //订单描述 model.Subject = "商学院报名"; //订单标题 model.OutTradeNo = Request["orderNo"]; //商户订单号,64个字符以内、可包含字母、数字、下划线;需保证在商户端不重复 model.TotalAmount = (Convert.ToInt32(dr.Rows[0]["Amount"])*1.0/100).ToString(); //订单总金额,单位为元,精确到小数点后两位 model.ProductCode = "FAST_INSTANT_TRADE_PAY"; //销售产品码,商家和支付宝签约的产品码 (如 FAST_INSTANT_TRADE_PAY) request.SetBizModel(model); //方法2: /************************************************** string Body = "商学院报名"; string Subject = "商学院报名"; string OutTradeNo = Request["orderNo"]; string TotalAmount = Request["amount"]; string ProductCode = "FAST_INSTANT_TRADE_PAY"; request.BizContent = "{" + " \"body\":\""+ Body + "\"," + " \"subject\":\""+ Subject + "\"," + " \"out_trade_no\":\""+ OutTradeNo + "\"," + " \"total_amount\":"+ TotalAmount + "," + " \"product_code\":\""+ ProductCode + "\"" + " }"; *********************************************************/ //调用SDK生成表单 AlipayTradePagePayResponse response = client.pageExecute(request); string form = response.Body; //Response.Write(form); return Content(form); } catch (Exception e) { throw new Exception(e.Message); } } #endregion
(3)面跳转同步通知页面
#region 页面跳转同步通知页面 /// <summary> /// 功能:页面跳转同步通知页面 /// </summary> public ActionResult ReturnUrl() { // http://localhost:10231/College/ReturnUrl? // total_amount =0.01 // ×tamp=2017-07-24+17%3A57%3A08 // &sign=******** // &trade_no=2017072421001004930200313969 // &sign_type=RSA2 // &auth_app_id=2016080500169628 // &charset=utf-8 // &seller_id=2088102169996595 // &method=alipay.trade.page.pay.return // &app_id=2016080500169628 // &out_trade_no=GM201707241756580000000001 // &version=1.0

(4)服务器异步通知页面

第6步:新建支付订单确认页面
<div class="zhezhaoceng dd" style="display: none"> <div class="duihuakuang ee" style="display: none"> <div class="success-alert "> <p>支付核实:</p> </div> <form method="post" id="OrderForm"> <div> <input type="hidden" name="OrderNo" id="orderNo" value="" /> <input type="hidden" name="Amount" id="amount" value="" /> <div> <p>商学院报名</p> <p>订单号:<span id="OrderNo"></span></p> <p>支付金额:<font color="red"><b><span id="Currency">¥</span><span id="Amount"></span></b></font></p> </div> <div> <input class="submit next-btn" type="button" value="立即支付" onclick="go_pay()" /> </div> </div> </form> </div> </div>
<div class="pay_method" style="display: none">
<div class="pay-alert ">
<p>支付方式</p>
<p><span id="pay_button"></span></p>
</div>
</div>
第7步:js处理
function go_pay() { $("#OrderForm").ajaxSubmit({ url: "/College/CreatePayForm", type: "post", success: function (data) { $(".detail-message8").css({ "display": "none" }); $(".dd").css({ "display": "none" }); $(".ee").css({ "display": "none" }); $(".pay_method").css({ "display": "none" }); $("#pay_button").html(data); } }); }
第8步:花生壳
由于支付宝异步回调测试需要将网站发布到公网,所以需要将本地域名映射到公网
(1)登录
用户名:************
密 码:*********
(2)实名认证
(3)添加映射
(4)访问将localhost换成zouke1220.oicp.net进行访问
http://zouke1220.oicp.net/College/Index
点击“报名”
点击“下一步”
function next_step() { $("#formID").ajaxSubmit({ url: "/College/ValidateUserInfo", type: "post", success: function (data) { if (data == "ok") { $(".detail-message8").css({ "display": "none" }); $(".detail-message6").css({ "display": "none" }); $(".detail-message7").css({ "display": "block" }); } else { alert(data); return false; } } }); }
点击“同意”
function iAgree(){ if ($("#checkedd").is(":checked")) { $(".detail-message6").css({ "display": "none" }); $(".detail-message7").css({ "display": "none" }); $(".detail-message8").css({ "display": "block" }); } else { return false; } }
点击“去支付”跳到订单确认页
function order_confirm() { $("#SignUpForm").ajaxSubmit({ url: "/College/SignUp", type: "post", success: function (data) { var obj=eval('(' + data + ')'); //json转json对象 if (obj.code == 0) { $(".dd").css({ "display": "block" }); $(".ee").css({ "display": "block" }); $("#OrderNo").html(obj.data.OrderNo); $("#Amount").html(obj.data.Amount); $("#orderNo").val(obj.data.OrderNo);
$("#amount").val(obj.data.Amount); } else { alert(obj.msg); return false; } } }); }
点击“立即支付”
function go_pay() { $("#OrderForm").ajaxSubmit({ url: "/College/CreatePayForm", type: "post", success: function (data) { $(".detail-message8").css({ "display": "none" }); $(".dd").css({ "display": "none" }); $(".ee").css({ "display": "none" }); $(".pay_method").css({ "display": "none" }); $("#pay_button").html(data); } }); }
点击“登录账户付款”
点击“下一步”
点击“确认付款”
自动跳转到异步回调页面,将支付成功信息插入数据库
http://zouke1220.oicp.net/College/NotifyUrl
并跳转到同步通知页面显示支付成功页面
http://zouke1220.oicp.net/College/ReturnUrl
第9步:所有测试通过后将第4步配置信息换成正式环境的
注:部分页面还需要美化,完整版项目参见:http://www.gmkcn.com/
