本文详细介绍了一种在Web应用中集成微信和支付宝支付的方法，包括生成二维码供用户扫码支付，以及后端如何处理支付回调验证的过程。文章深入探讨了支付流程中的关键步骤，如生成支付链接、验证支付结果、订单状态更新等。
1、前端调用后台生成的二维码
var wxcode = "/index.php/WebPay/thirdPaymentQrcode/user_id/52398/payType/weChat/fromType/3/price/";
var alipycode = "/index.php/WebPay/alipyCode?url=/index.php/WebPay/thirdPaymentQrcode/user_id/52398/payType/aliPay/fromType/3/price/";
2、用户扫码支付， 后端回调验证
