我的日志如下所示：

200 59903 0.056 - [24/Jun/2020:00:06:56 +0530] "GET /xxxxx/xxxxx/xxxxx HTTP/1.1" xxxxx.com [xxxx:4900:xxxx:b798:xxxx:c8ba:xxxx:6a23] - - xxx.xxx.xxx.xxx - - -  "http://xxxxx/xxxxx/xxxxx" 164551836 1 HIT "-" "-" "Mozilla/5.0 (Linux; Android 9; Mi A1 Build/PKQ1.180917.001; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/77.0.3865.92 Mobile Safari/537.36" "-" "-" "dhDebug=-" "-" - -

这两个日志几乎相同，除了最后一个包含dhDebug.

这就是我的parsers.conf样子：

[PARSER]
    Name         head
    Format       regex
    Regex        (?<responseCode>\d{3})\s(?<responseSize>\d+)\s(?<responseTime>\d+.\d+)\s.*?\s\[(?<time>.*?)\]\s"(?<method>.*?)\s(?<url1>.*?)\s(?<protocol>.*?)"\s(?<servedBy>.*?)\s(?<Akamai_ip1>.*?)\s(?<ClientId_ip2>.*?)\s(?<ip3>.*?)\s(?<lb_ip4>.*?)\s(?<ip5>.*?)\s(?<ip6>.*?)\s(?<ip7>.*?)\s+"(?<url2>.*?)".*?".*?"\s".*?"\s"(?<agentInfo>.*?)"
    Time_Key     time
    Time_Format  %d/%b/%Y:%H:%M:%S %z
    Time_Keep    On
    Types responseTime:float

请提出有关如何dhDebug在适用于两种日志类型的同一正则表达式中实现单独键值对中的信息的任何想法。

已编辑！！

您可以使用(?:case1|case2)case1: is null 和 case2: is not null

所以正则表达式将是：

(?<responseCode>\d{3})\s(?<responseSize>\d+)\s(?<responseTime>\d+.\d+)\s.*?\s\[(?<time>.*?)\]\s"(?<method>.*?)\s(?<url1>.*?)\s(?<protocol>.*?)"\s(?<servedBy>.*?)\s(?<Akamai_ip1>.*?)\s(?<ClientId_ip2>.*?)\s(?<ip3>.*?)\s(?<lb_ip4>.*?)\s(?<ip5>.*?)\s(?<ip6>.*?)\s(?<ip7>.*?)\s+"(?<url2>.*?)".*?".*?"\s".*?"\s"(?<agentInfo>.*?)"\s"-"\s"-"\s"dhDebug=(?:-|appVersion=(?<appVersion>.*?)&osVersion=(?<osVersion>.*?)&clientId=(?<clientId>.*?)&conn_type=(?<conn_type>.*?)&conn_quality=(?<conn_quality>.*?)&sessionSource=(?<sessionSource>.*?)&featureMask=(?<featureMask>.*?)&featureMaskV1=(?<featureMaskV1>.*?))"

有了这个，对于第一个日志行的 dhDebug 的每个字段名称和第二个日志行的字段名称，您将获得 null。

您可以在http://grokdebug.herokuapp.com/对其进行测试
