我使用的是SDK开发

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
