这里主要使用日志的方式进行debug
环境依赖
项目对openresty包的依赖比较高，所以环境基础都在openresty下进行
openresty的使用
openresty下载地址
下载完成后解压，具体使用方式和nginx没有什么区别，主要依赖文件是一下几个
nginx.exe # 负责启动服务
conf/nginx.conf # nginx的配置文件 使用lua脚本主要也是在这里配置
logs # 日志查看 排错
lua链接mysql校验用户
这里拿lua链接mysql为例

}启动openresty
双击 nginx.exe即可，浏览器输入http://localhost:8765进入启动页面
调试过程中，每次点击nginx.exe都会启动新的线程，导致有时候更新的项目但是打到的请求还是在老的配置服务上，为确保每次请求都是最新的，最好把线程都删掉
windows
# 展示线程
tasklist /fi "imagename eq nginx.exe"
# 杀掉线程
taskkill /fi "imagename eq nginx.exe" -f
Lua脚本校验
浏览器输入http://localhost:8765/testlua进入插件校验页面
运行的日志和错误信息都可以在logs/access.log&error.log中找到，由于这里已经是处理完成的脚本信息，如何解决问题这里不做展示。
需要注意的是，在脚本文件中ngx.log(ngx.ERR, "xxxx")最好都设置成err级别，别的级别好像不会展示在日志中
校验
Error
Success
