When using socket.IO in a Node.js server, is there an easy way to get the IP address of an incoming connection? I know you can get it from a standard HTTP connection, but socket.io is a bit of a different beast.
回答1:
Okay, as of 0.7.7 this is available, but not in the manner that lubar describes. I ended up needing to parse through some commit logs on git hub to figure this one out, but the following code does actually work for me now:
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);
});
回答2:
for 1.0.4:
io.sockets.on(‘connection‘, function (socket) {
var socketId = socket.id;
var clientIp = socket.request.connection.remoteAddress;
console.log(clientIp);
});

If you use an other server as reverse proxy all of the mentioned fields will contain localhost. The easiest workaround is to add headers for ip/port in the proxy server.
Example for nginx: add this after your proxy_pass
:
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Real-Port $remote_port;
This will make the headers available in the socket.io node server:
var ip = socket.handshake.headers["x-real-ip"];
var port = socket.handshake.headers["x-real-port"];
Note that the header is internally converted to lower case.
If you are connecting the node server directly to the client,
var ip = socket.conn.remoteAddress;
works with socket.io version 1.4.6 for me.
回答4:
For latest socket.io version use
socket.request.connection.remoteAddress
For example:
var socket = io.listen(server);
socket.on(‘connection‘, function (client) {
var client_ip_address = socket.request.connection.remoteAddress;
}
beware that the code below returns the Server‘s IP, not the Client‘s IP
var address = socket.handshake.address;
console.log(‘New connection from ‘ + address.address + ‘:‘ + address.port);

Using the latest 1.0.6
version of Socket.IO
and have my app deployed on Heroku
, I get the client IP
and port
using the headers
into the socket handshake
:
var socketio = require(‘socket.io‘).listen(server);
socketio.on(‘connection‘, function(socket) {
var sHeaders = socket.handshake.headers;
console.info(‘[%s:%s] CONNECT‘, sHeaders[‘x-forwarded-for‘], sHeaders[‘x-forwarded-port‘]);
}

This seems to work:
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);
});
回答7:
Since socket.io 1.1.0, I use :
io.on(‘connection‘, function (socket) {
console.log(‘connection :‘, socket.request.connection._peername);
// connection : { address: ‘192.168.1.86‘, family: ‘IPv4‘, port: 52837 }
}
Edit : Note that this is not part of the official API, and therefore not guaranteed to work in future releases of socket.io.

Version 0.7.7 of Socket.IO now claims to return the client‘s IP address. I‘ve had success with:
var socket = io.listen(server);
socket.on(‘connection‘, function (client) {
var ip_address = client.connection.remoteAddress;
}
回答9:
Very easy. First put
io.sockets.on(‘connection‘, function (socket) {
console.log(socket);
You will see all fields of socket. then use CTRL+F and search the word address. Finally, when you find the field remoteAddress use dots to filter data. in my case it is
console.log(socket.conn.remoteAddress);
回答10:
From reading the socket.io source code it looks like the "listen" method takes arguments (server, options, fn) and if "server" is an instance of an HTTP/S server it will simply wrap it for you.
So you could presumably give it an empty server which listens for the ‘connection‘ event and handles the socket remoteAddress; however, things might be very difficult if you need to associate that address with an actual socket.io Socket object.
var http = require(‘http‘)
, io = require(‘socket.io‘);
io.listen(new http.Server().on(‘connection‘, function(sock) {
console.log(‘Client connected from: ‘ + sock.remoteAddress);
}).listen(80));
Might be easier to submit a patch to socket.io wherein their own Socket object is extended with the remoteAddress property assigned at connection time...
回答11:
Latest version works with:
console.log(socket.handshake.address);
回答12:
on socket.io
1.3.4 you have the following possibilities.
socket.handshake.address
,
socket.conn.remoteAddress
or
socket.request.client._peername.address
回答13:
use socket.request.connection.remoteAddress
回答14:
I have found that within the socket.handshake.headers there is a forwarded for address which doesn‘t appear on my local machine. And I was able to get the remote address using:
socket.handshake.headers[‘x-forwarded-for‘]
This is in the server side and not client side.
回答15:
In socket.io 2.0: you can use:
socket.conn.transport.socket._socket.remoteAddress
works with transports: [‘websocket‘]
回答16:
In 1.3.5 :
var clientIP = socket.handshake.headers.host;
回答17:
socket.handshake.headers[‘x-forwarded-for‘].split(",")[0]
As of socket 3.1.2
Get the client's IP address in socket.io
