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

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/
