顺便问一下，如何用最简单的非异步的方式获取本机ip地址

我给你一个function,是目前我的网站正在使用的http://sogego.com

exports.getClientIP = function(req){ var ipAddress; var headers = req.headers; var forwardedIpsStr = headers[‘x-real-ip’] || headers[‘x-forwarded-for’]; forwardedIpsStr ? ipAddress = forwardedIpsStr : ipAddress = null; if (!ipAddress) { ipAddress = req.connection.remoteAddress; } return ipAddress; }

这个方法可以判断你是否使用了nginx和一般情况

@snoopy 那么多异步的方法, Node 设计得好邪门呐非异步的话有么?

@jiyinyiyong @snoopy @a272121742 os.networkInterfaces() 参考这里：http://nodejs.org/api/os.html#os_os_networkinterfaces

Get a list of network interfaces:

{ lo0: 
   [ { address: '::1', family: 'IPv6', internal: true },
     { address: 'fe80::1', family: 'IPv6', internal: true },
     { address: '127.0.0.1', family: 'IPv4', internal: true } ],
  en1: 
   [ { address: 'fe80::cabc:c8ff:feef:f996', family: 'IPv6',
       internal: false },
     { address: '10.0.1.123', family: 'IPv4', internal: false } ],
  vmnet1: [ { address: '10.99.99.254', family: 'IPv4', internal: false } ],
  vmnet8: [ { address: '10.88.88.1', family: 'IPv4', internal: false } ],
  ppp0: [ { address: '10.2.0.231', family: 'IPv4', internal: false } ] }

@leizongmin 表示关于 OS 学得太散, 看过文档很多不懂对应什么
