当时做微信H5支付的时候,查询网上资料确实不是很多,都是断断续续,并不完整,花了两天时间,把支付搞定了,写个博客记录一下,也希望朋友少走点坑,代码是完全没问题的,现在把代码一一贴出来.强调一下是微信H5支付,不是公众号支付,不是app支付(当然你app是H5做的就可以)

}这样基本上就大功告成,只要你微信的参数没问题,绝对可以正常跑起来,使用微信外部浏览器就可以调出微信支付,有什么不清楚的可以在下面留言.做这个功能我还去下了csdn一些demo,花了我好多积分,现在我无偿分享出来哈.
需要demo的可以去我发布出来的资源下载,积分很便宜,我集合了两个大神的demo,当时花了我三十多积分,这是下载地址:https://download.csdn.net/download/leigelg/10438468
