自己写的一个扫描网址标题的小工具.
功能:遍历指定范围的IP,根据IP扫描网页的标题,并记录(支持二级重定向网页的扫描)
自动记录采集日志到D盘的net_collect.log文件中.
类型:控制台程序
实现语言:C#
需要的环境: .NET 3.5
可选的环境:Oracle数据库
相关的缺省值说明:
缺省(直接按回车即是缺省值)Oracle数据库用户:scott
缺省Oracle数据库密码:tigger
缺省Oracle数据库连接标识符:orcl (即TNSNAME名称)
缺省的http连接超时时间:6秒
缺省启用数据库来记录采集到的信息
缺省不启用扫描完成后自动关机
(篇幅原因,数据库连接类这里就不贴了)
