我的个人网站如何实现支付功能？

创新互联建站专业为企业提供北流网站建设、北流做网站、北流网站设计、北流网站制作等企业网站建设、网页设计与制作、北流企业网站模板建站服务，十余年北流做网站经验，不只是建网站，更提供有价值的思路和整体网络服务。

想必很多程序员都有过想开发一个自己的网站来获得一些额外的收入，但做这件事会遇到支付这个问题。目前个人网站是无法实现支付功能的。

今天我就给大家分享一下我的实现方案：《基于xposed逆向微信、支付宝、云闪付来实现个人免签支付方案》

测试页面(点我)

接下来给大家简单分享一下实现过程，这个过程其实是非常复杂的，关键点在于如何逆向微信支付宝云闪付这些App，找到核心函数钩子，然后写一个hook程序来模拟调用这些方法，来实现根据服务端传过来的金额，订单号自动调用微信支付宝生成支付二维码的函数得到相对应的支付二维码再传给服务端，然后监听微信支付宝的支付成功消息最终回调给服务端实现支付成功通知。这里面用到的核心技术点有：xposed逆向框架、apk反编译，网络抓包，apk动态调试等技术。

像微信支付宝这些apk反编译后的代码基本上都是天书一样的，严重混淆过的代码。想从中找到核心代码并非易事，下面我贴一些核心代码吧。
