可变source包含IP地址的，我试图在阵列ips得到，但不顺心的事，我无法找到错误...收集所有的IP（V4，V6）使用正则表达式失败

回答：

由于您没有提供可验证的样本，我将根据Syzdek的出色ipv6-regex-test.sh提供端到端的demo工作。

正则表达式表达：

(([0-9a-fA-F]{1,4}:){7,7}[0-9a-fA-F]{1,4}| ([0-9a-fA-F]{1,4}:){1,7}:| ([0-9a-fA-F]{1,4}:){1,6}:[0-9a-fA-F]{1,4}| ([0-9a-fA-F]{1,4}:){1,5}(:[0-9a-fA-F]{1,4}){1,2}| ([0-9a-fA-F]{1,4}:){1,4}(:[0-9a-fA-F]{1,4}){1,3}| ([0-9a-fA-F]{1,4}:){1,3}(:[0-9a-fA-F]{1,4}){1,4}| ([0-9a-fA-F]{1,4}:){1,2}(:[0-9a-fA-F]{1,4}){1,5}| [0-9a-fA-F]{1,4}:((:[0-9a-fA-F]{1,4}){1,6})| :((:[0-9a-fA-F]{1,4}){1,7}|:)| fe80:(:[0-9a-fA-F]{0,4}){0,4}%[0-9a-zA-Z]{1,}| ::(ffff(:0{1,4}){0,1}:){0,1} ((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3} (25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])| ([0-9a-fA-F]{1,4}:){1,4}: ((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3} (25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])) |((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])

演示代码：

var ips = new Array();;  
const regex = /(([0-9a-fA-F]{1,4}:){7,7}[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,7}:|([0-9a-fA-F]{1,4}:){1,6}:[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,5}(:[0-9a-fA-F]{1,4}){1,2}|([0-9a-fA-F]{1,4}:){1,4}(:[0-9a-fA-F]{1,4}){1,3}|([0-9a-fA-F]{1,4}:){1,3}(:[0-9a-fA-F]{1,4}){1,4}|([0-9a-fA-F]{1,4}:){1,2}(:[0-9a-fA-F]{1,4}){1,5}|[0-9a-fA-F]{1,4}:((:[0-9a-fA-F]{1,4}){1,6})|:((:[0-9a-fA-F]{1,4}){1,7}|:)|fe80:(:[0-9a-fA-F]{0,4}){0,4}%[0-9a-zA-Z]{1,}|::(ffff(:0{1,4}){0,1}:){0,1}((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])|([0-9a-fA-F]{1,4}:){1,4}:((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9]))|((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])/g;  
const str = `3ffe:1900:4545:3:200:f8ff:fe21:67cf  
fe80:0:0:0:200:f8ff:fe21:67cf  
192.168.0.1`;  
let m;  
while ((m = regex.exec(str)) !== null) {  
    // This is necessary to avoid infinite loops with zero-width matches  
    if (m.index === regex.lastIndex) {  
     regex.lastIndex++;  
    }  
    // capturing group 0: full match  
    console.log(m[0]);  
    ips.push(m[0]);  
}  
console.log(ips);
