nginx日志回放压测

• 解析日志进行回放压测，模拟后端服务器慢等各种异常情况

方案说明

• 客户端解析access.log构建请求的host,port,url,body
• 把后端响应时间，后端响应状态码，后端响应大小放入header头中
• 后端服务器获取相应的header，进行模拟响应body大小，响应状态码，响应时间

使用方式

• 拷贝需要测试的access.log的日志到logs文件夹里面
• 搭建需要测试的nginx服务器，并且配置upstream 指向后端服务器断端口
• 启动后端服务器实例 server/backserver/main.go
• 进行压测 bin/wrk -c30 -t1 -s conf/nginx_log.lua http://localhost:8095
