最近项目中用到了微信支付,于是找到了这篇资料,为了防止遗忘转载一下,先谢过作者。原文地址:http://www.360us.net/article/22.html

最近把支付宝、银联和微信支付全都做了一遍,目前做的都还只涉及到消费的功能。
做下来感觉就是各个平台的支付流程都是大同小异,签名方式也是一样的。
这里主要总结一下微信支付公众号支付的一些东西。
微信公众号支付的主要流程如下:
1、生成我们自己系统的订单。
2、调用微信支付的统一下单接口把订单信息推给微信。
3、在第二部会返回一个预支付会话标识,然后凭这个标识用JS去调用支付操作。

关于支付页面的url问题,微信要求是最后必须要有“/”,我看到很多文章说不适合MVC结构的程序,我的情况是否定的,MVC结构一样可以。<br>比如url是这个:<codecourier new font-size:12.6000003814697px padding:2px color:rgb background-color:rgb>http://www.example.com/payment/wechatpay/ ,url里面<codecourier new font-size:12.6000003814697px padding:2px color:rgb background-color:rgb>payment是<codecourier new font-size:12.6000003814697px padding:2px color:rgb background-color:rgb>controller,<codecourier new font-size:12.6000003814697px padding:2px color:rgb background-color:rgb>wechatpay是<codecourier new font-size:12.6000003814697px padding:2px color:rgb background-color:rgb>action,这有问题吗?<br>一样可以访问,可以支付,是不是一个真正的目录,在微信看来就是,实际上其实不是。<phelvetica neue grande sans gb yahei micro hei font-size:14px
