Node.js Socket.io握手地址值更改

这很奇怪。Socket.io版本~1.3

io.sockets.on('connection', function (socket) {
    console.log('Client connected from: ' + socket.handshake.address);
}

返回

然而

io.sockets.on('connection', function (socket) {
    console.log(socket.handshake);
    console.log('Client connected from: ' + socket.handshake.address);
}

为什么?？是否有一些ES6代理在路上？我想可能有一些奇怪的JS转换魔法，但似乎不是这样。

：ffff:127.0.0.1

是

127.0.0.1

的IPv6版本，

：：1

是两者的IPv6快捷方式

有关类似的问题，请参见。

谢谢。你能告诉我转换发生在哪里吗？为什么只有当我转储整个握手对象时才会发生转换？我得到了，所以也许这是依赖于控制台。日志实现？我跟踪它进一步下去，但我的C++和OS API /管道知识是不够的。
