nodejs获取本机内网和外网ip地址的实现代码
实现代码：
varos=require('os');
functiongetLocalIP(){
varmap=[];
varifaces=os.networkInterfaces();
console.log(ifaces);
for(vardevinifaces){ if(dev.indexOf('eth0')!=-1){ vartokens=dev.split(':'); vardev2=null; if(tokens.length==2){ dev2='eth1:'+tokens[1]; }elseif(tokens.length==1){ dev2='eth1'; } if(null==ifaces[dev2]){ continue; }
//找到eth0和eth1分别的ip varip=null,ip2=null; ifaces[dev].forEach(function(details){ if(details.family=='IPv4'){ ip=details.address; } }); ifaces[dev2].forEach(function(details){ if(details.family=='IPv4'){ ip2=details.address; } }); if(null==ip||null==ip2){ continue; }
//将记录添加到map中去 if(ip.indexOf('10.')==0|| ip.indexOf('172.')==0|| ip.indexOf('192.')==0){ map.push({"intranet_ip":ip,"internet_ip":ip2}); }else{ map.push({"intranet_ip":ip2,"internet_ip":ip}); } } } returnmap; }
console.log(getLocalIP());
