如何使用socket.io獲取用戶的IP地址？

Question

在我的節點應用程序中，我需要獲取使用socket.io.的用戶的IP地址，我嘗試了下面的代碼，但直到我得到127.0.0.1.How我可以得到我的IP地址。

1.

var io = require("socket.io").listen(server); 

    io.sockets.on("connection", function (socket) { 
    var address = socket.handshake.address; 
    console.log("New connection from " + address.address + ":" + address.port); 
} 

2.

var io = require('socket.io').listen(80); 
    io.sockets.on('connection', function (socket) { 
    var endpoint = socket.manager.handshaken[socket.id].address; 
    console.log('Client connected from: ' + endpoint.address + ":" + endpoint.port); 
    }); 

3.

var socket = io.listen(server); 
     socket.on('connection', function(client){ 
      var ip_address = client.connection.remoteAddress; 
     }); 

Answer 1

試試這個，這對我的作品。

Var client = require('socket.io').listen(8080).sockets; 

client.on('connection',function(socket){ 
var clientIpAddress= socket.request.socket.remoteAddress; 
});
