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,如果不懂怎么设置，就查看这个帖：http://bbs.itheima.com/thread-300392-1-1.html)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_13.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

5、准备下面几个PHP脚本1)在Wxpay.config.php脚本中，把相关配置填写正确，如下所示：
