static string serverUrl = "https://openapi.alipaydev.com/gateway.do";
static string app_id = "**"; //开发者的应用ID
static string format = "JSON";
static string charset = "utf-8";
static string version = "1.0";
string UID = "2088102169707816";//卖家支付宝账户号
//商户私钥
static string merchant_private_key = "***";
//支付宝公钥
static string alipay_public_key = "***";

这里的app_id,merchant_private_key,alipay_public_key 我就没有列出来了，获取的方法需要自己去支付宝平台完成一些操作进行获取
在用户点击网站付款时，我们需要唤醒支付宝，来进行支付

具体发送给支付宝的参数，自行去查看
执行方法后，买家输入自己的支付宝账号密码进行支付，支付成功的结果，支付宝会以post的方式异步请求你的SetNotifyUrl的地址
这个SetNotifyUrl的地址必须要外网可以访问，支付宝的请求才能进来
买家支付成功，商家修改订单状态和数据库的操作，都在异步请求中执行
同步请求
