应用放在腾讯云上，但是日志莫名其妙有一些陌生的IP，查了一下地址标注在了后面，求大牛指导是什么原因

Answer 1

應用程式發佈到網路上，除了正常訪問，一般還會有以下三種情況：

1. 爬蟲訪問
   這種情況在tomcat打印access日誌時，把user-agent 打印出來就可以看到，會有搜索引擎名字，如baidu、sogou等，而且一般搜索引擎IP都可以反查到，可以IP查詢（http://www.ip138.com）反查一下

2. 安全站點掃描
   如果使用360或其他站長安全掃描工具，也會有大量IP過來訪問

3. 惡意工具掃描
   與第二項類似，安全掃描會透過先前設定好的掃描點逐步掃描，也會造成大量IP存取

排查時主要關注掃描IP是否搜尋引擎或安全站點掃描IP，以及掃描的目錄點來綜合判斷，如果判斷為惡意IP，可以配合防火牆規則進行屏蔽即可。

Answer 2

額，被爬蟲爬到了…

把User-Agent也打出來吧，會大開眼界的 :-)

Answer 3

下面這條應該不是爬蟲，是掃描程序吧
