HP微信支付开发过程，分享给大家，供大家参考，具体内容如下
1.开发环境
Thinkphp 3.2.3
微信：服务号，已认证
开发域名：http://test.paywechat.com (自定义的域名，外网不可访问)
2.需要相关文件和权限
微信支付需申请开通
微信公众平台开发者文档：http://mp.weixin.qq.com/wiki/home/index.html
微信支付开发者文档：https://pay.weixin.qq.com/wiki/doc/api/index.html
微信支付SDK下载地址：https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1
3.开发
下载好微信支付PHP版本的SDK，文件目录为下图：
把微信支付SDK的Cert和Lib目录放入Thinkphp，目录为
现在介绍微信支付授权目录问题，首先是微信支付开发配置里面的支付授权目录填写，
然后填写JS接口安全域。
最后设置网页授权
这些设置完，基本完成一半,注意设置的目录和我thinkphp里面的目录。
4.微信支付配置
把相关配置填写正确。

<p>到这里基本上完成，可以在微信端打开http://域名/Charge/index.php/Test/index/<br ?-->
我的环境，HTTP服务器没有重写url，微信支付继续探索中，有些地方可能写的有问题或不足，望大家谅解，互相学习。
