Question

我找不到适合我要标识的元素的正则表达式

我要分析的日志文件示例：

[20190625-10:20:20] [INFO ] A connection received from: ::ffff:192.168.1.32 port 52166
[20190625-10:19:22] [INFO ] xrdp_wm_log_msg: login failed for display 0
[20190625-10:20:20] [INFO ] A connection received from: ::ffff:192.168.1.32 port 52166
[20190625-10:20:20] [INFO ] A connection received from: ::ffff:192.168.1.32 port 52167
[20190625-10:21:19] [INFO ] A connection received from: ::ffff:192.168.1.32 port 52176
[20190625-10:21:19] [INFO ] A connection received from: ::ffff:192.168.1.32 port 52177

我想找到正则表达式来检测这种样式的行：

[20190625-11:47:51] [INFO ] A connection received from: ::ffff:192.168.1.32 port 55737

我已经测试过failregex = ^.*ffff:<HOST> port *$

Not ok

Answer 1

我不太确定，只是猜测我们可能想要一个类似于以下内容的表达式：

(\[[0-9]{8}.+?A connection received from: ::ffff:.+?port\s+[0-9]+)

带有s标志。
