最近在做一个支付模块，支付宝账户手续复杂但审核快，微信支付手续较少但审核慢，但都需要花钱。
android 客户端的处理并不复杂，只是将商品的名称 描述 价格 等一些其他的一些属性上传本地服务器，由服务器为商品签名加密再返回到本地，此时数据经过特殊处理，再将数据上传给马云爸爸就ok了。
项目让我恼火的是总是出ali64错误，其实这主要是公私钥不匹配，个人建议这么排查这个错误：
1.先用支付宝公私钥生成工具再生成一遍公私钥，替换掉开发平台的以及服务器的钥匙
2.如果还是触发ali64错误，检查一遍商品信息里的格式：(最好是客户端上传商品信息，别把官方demo里的那个生成orderinfo的放在客户端里，把他放在服务器里做)，这里再出问题应该都是服务器那边的差错，因为客户端只是起到一个网络请求数据的作用。
