3.1配置相关文件
1.安装包在给的第8天资料里，这个软件是为了给当前局域网内的ip一个公网的域名：
2.在下面的地址栏输入cmd：
3.到官网获取隧道Authtoken：
4.输入如下代码，粘贴token即可：
5.会生成一个配置文件：
3=6.输入下面的代码：
cpolar.exe http 80807.获得临时的域名：
8.可以通过域名+doc.html进行访问：
9.在配置项application.yml中加入如下代码：
java
sky:
wechat:
appid: ${sky.wechat.appit}
secret: ${sky.wechat.secret}
mchid: ${sky.wechat.mchid}
mchSerialNo: ${sky.wechat.mchid}
privateKeyFilePath: ${sky.wechat.privateKeyFilePath}
apiV3Key: ${sky.wechat.apiV3Key}
weChatPayCertFilePath: ${sky.wechat.weChatPayCertFilePath}
notifyUrl: ${sky.wechat.notifyUrl}
refundNotifyUrl: ${sky.wechat.refundNotifyUrl}10.在application-dev.yml文件中写入如下的代码
（要注意notifyUrl和refundNotifyUrl，这两个url的前半部分都是cpolar临时生成的公网ip，因为是临时域名，所以每次生成的都会变化，以后要注意修改）：
notifyUrl和refundNotifyUrl这俩地址是由微信后台请求的。
java
wechat:
