quick-cocos2d-x 实现在lua里面完成android支付宝的接入

一、支付宝注册是很麻烦的一个过程，本文就不解释了，想了解的去官网看下注册流程。然后下载他们的sdk-WS_SECURE_PAY_SDK。

二、开始集成。

1、在eclipse里面导入alipay的工程库 WS_SECURE_PAY_SDK/paydemo/Android_SDK/alipay_lib

然后在自己的项目里面引用一下。

2、写自己的java类。keys.java

/*
 *
 *  提示：如何获取安全校验码和合作身份者id
 *  1.用您的签约支付宝账号登录支付宝网站(www.alipay.com)
 *  2.点击“商家服务”(https://b.alipay.com/order/myorder.htm)
 *  3.点击“查询合作者身份(pid)”、“查询安全校验码(key)”
 */

3、在lua里面调用Alipay的静态方法payAli，把你需要的参数传到payAli的方法里面，包括回调函数。在java里面通

Cocos2dxLuaJavaBridge.callLuaFunctionWithString来回调lua的方法，然后在lua里面告诉服务器玩家的支付结果，服务器也需要去验证一次支付，服务器端就不说了。
