日誌格式如下：

223.74.135.248 - - [11/May/2017:11:19:47 +0800] "POST /login/getValidateCode HTTP/1.1" 404 14227 "http://www.yidianchina.com/login/getValidateCode" "Mozilla/4.0 (compatible; MSIE 9.0; Windows NT 6.1)"

分別是IP，訪問時間，請求方法，請求URI，HTTP協議，響應狀態碼，響應體大小，referer，客戶瀏覽器。

除了HTTP協議不用截取，其他的都匹配後，存儲到數據庫，以備後續分析。
