在socket.io中使用代理时没有获取远程地址

Question

In my socket.io code,

socket.sockets.on('connection', function(client){ 
    var ip = client.handshake.address.address;
    ..
}

ip always returns 127.0.0.1 and this is because the server sits behind a proxy. How do I get remote address properly ?

Edit: I am using http-proxy

Answer 1

yes, this is working for me.

client.handshake.headers['x-forwarded-for'] || client.handshake.address.address;

I am properly getting the remote IP address and not 127.0.0.1

Answer 2

在版本> 1.0中，语法类似：

socket.handshake.headers['x-forwarded-for'] || socket.request.connection.remoteAddress;

Answer 3

For people who may come from Google, using NGINX: none of these worked for me, I followed the answer in this other question and modified my proxy_pass , to create a new header that node could then use. Don't forget to call sudo systemctl restart nginx after.
