node 獲取本機主機名和ip

/**獲取本機ip**/
function getIPAdress(){
    var interfaces = require('os').networkInterfaces();
    for(var devName in interfaces){
        var iface = interfaces[devName];
        for(var i=0;i<iface.length;i++){
            var alias = iface[i];
            if(alias.family === 'IPv4' && alias.address !== '127.0.0.1' && !alias.internal){
                return alias.address;
            }
        }
    }
}

 

var hostname = require("os").hostname();//主機名
