提取字符串中"D999"后面的IP地址

package main

import (
	"fmt"
	"regexp"
)

func main() {
	str := "[通讯兵] 收到网络图: netmap: self: [21162] auth=machine-authorized u=? debug={\"DisableLogTail\":true} [100.64.1.70/32] [Hv9Py] d:59be947163c3243a D999 100.64.1.7      :   222.168.43.66:36941   172.16.22.148:60755   172.16.22.150:60755      172.17.0.1:60755      172.19.0.1:60755   192.168.1.110:60755"

	re := regexp.MustCompile(`D999\s+(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})`)
	match := re.FindStringSubmatch(str)
	if len(match) >= 2 {
		ip := match[1]
		fmt.Println("提取到的IP地址:", ip)
	} else {
		fmt.Println("未找到匹配的IP地址")
	}

PS E:\TEXT\test> go run .\gogo.go
提取到的IP地址: 100.64.1.7
PS E:\TEXT\test>

正则表达式 D999\s+(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}) 用于匹配以"D999"开头，后面跟着一个或多个空格，并且紧跟着一个IP地址的字符串。

(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}) 用于匹配IP地址的部分，其中 \d{1,3} 表示一个由 1 到 3 位数字组成的部分，\. 用于匹配点号分隔符。
