[英]How to get the correct IP address of a client into a Node socket.io app hosted on Heroku?
我最近在Heroku上使用Express和socket.io托管了我的第一個Node應用程序,需要找到客戶端的IP地址。 到目前為止,我已經嘗試過socket.manager.handshaken[socket.id].address
, socket.handshake.address
和socket.connection.address
,它們都沒有給出正確的地址。
應用程序: http : //nes-chat.herokuapp.com/ (還包含指向GitHub repo的鏈接)
要查看已連接用戶的IP,請訪問: http : //nes-chat.herokuapp.com/users
誰知道問題是什么?
客戶端IP地址在X-Forwarded-For
HTTP標頭中傳遞。 我還沒有測試過,但看起來socket.io在確定客戶端IP時已經考慮到了這一點 。
您也應該能夠自己抓住它,這是一個指南 :
function getClientIp(req) {
var ipAddress;
// Amazon EC2 / Heroku workaround to get real client IP
var forwardedIpsStr = req.header('x-forwarded-for');
if (forwardedIpsStr) {
// 'x-forwarded-for' header may return multiple IP addresses in
// the format: "client IP, proxy 1 IP, proxy 2 IP" so take the
// the first one
var forwardedIps = forwardedIpsStr.split(',');
ipAddress = forwardedIps[0];
}
if (!ipAddress) {
// Ensure getting client IP address still works in
// development environment
ipAddress = req.connection.remoteAddress;
}
return ipAddress;
};
你可以在一行中完成。
function getClientIp(req) {
// The X-Forwarded-For request header helps you identify the IP address of a client when you use HTTP/HTTPS load balancer.
// http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/TerminologyandKeyConcepts.html#x-forwarded-for
// If the value were "client, proxy1, proxy2" you would receive the array ["client", "proxy1", "proxy2"]
// http://expressjs.com/4x/api.html#req.ips
var ip = req.headers['x-forwarded-for'] ? req.headers['x-forwarded-for'].split(',')[0] : req.connection.remoteAddress;
console.log('IP: ', ip);
}
我想將此添加到中間件並將IP作為我自己的自定義對象附加到請求。
以下對我有用。
Var client = require('socket.io').listen(8080).sockets;
client.on('connection',function(socket){
var clientIpAddress= socket.request.socket.remoteAddress;
});
