我需要帮助将正则表达式与 golang 集成。我想解析日志文件并创建一个在https://regex101.com/r/p4mbiS/1/上看起来很好的正则表达式


日志线如下所示：


57.157.87.86 - - [06/Feb/2020:00:11:04 +0100] "GET /?parammore=1&customer_id=1&version=1.56&param=meaningful&customer_name=somewebsite.de&some_id=4&cachebuster=1580944263903 HTTP/1.1" 204 0 "https://www.somewebsite.com/more/andheresomemore/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0"

像这样的正则表达式：


(?P<ip>([^\s]+)).+?\[(?P<localtime>(.*?))\].+?GET\s\/\?(?P<request>.+?)\".+?\"(?P<ref>.+?)\".\"(?P<agent>.+?)\"

命名组的结果应如下所示：


ip: 57.157.87.86



请求：parammore=1&customer_id=1&...HTTP/1.1


参考：https ://www.somewebsite.com/more/andheresomemore/


代理：Mozilla/5.0（Windows NT 10.0；Win64；x64；rv:72.0）...


regex101.com 生成对我不起作用的 golang 代码。我试图改进它但没有成功。


golang 代码只返回整个字符串而不是组。


package main


import (

    "regexp"

    "fmt"

)


func main() {

    var re = regexp.MustCompile(`(?P<ip>([^\s]+)).+?\[(?P<localtime>(.*?))\].+?GET\s\/\?(?P<request>.+?)\".+?\"(?P<ref>.+?)\".\"(?P<agent>.+?)\"`)

    var str = `57.157.87.86 - - [06/Feb/2020:00:11:04 +0100] "GET /?parammore=1&customer_id=1&version=1.56&param=meaningful&customer_name=somewebsite.de&some_id=4&cachebuster=1580944263903 HTTP/1.1" 204 0 "https://www.somewebsite.com/more/andheresomemore/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0"`

    

    if len(re.FindStringIndex(str)) > 0 {

        fmt.Println(re.FindString(str),"found at index",re.FindStringIndex(str)[0])

    }

}
