Hi, I've an issue where the sockets is repeatedly disconnecting and connecting to my nodeJs backend server. And I have configured Nginx as Reverse Proxy for WebSocket for 2 nodeJs webservers.
Such as,
server {
listen 5000;
server_name localhost;
access_log /data/logs/nginx/webserver/access.log main;
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://webserver-nodes;
# enable WebSockets
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
upstream webserver-nodes {
# enable sticky session based on IP
# ip_hash;
server 172.xx.xx.xx:5001;
server 172.xx.xx.xx:5002;
}
The webserver socket.op version is "socket.io": "^2.4.1".
According this table:
| Client version | Socket.IO server |
|---|---|
| 0.9.x | 1.x |
| 1.x | 2.x |
| 2.x | 3.x / 4.x |
I selected socket.io-client-v1.0.0/1.0.1.
I have one client to connect the webserver.
My code is here:
try
{
String url ="http://xx.xx.xx.xx:5000";
IO.Options options = new IO.Options();
options.forceNew = true;
options.reconnectionDelay = 1000;
options.timeout = 5000;
socket = IO.socket(URI.create(url), options);
//socket.connect();
}catch (Exception ex)
{
log.error("connect error:"+ex);
}
when I set url ="http://xx.xx.xx.xx:5000".
I find the socket java client disconnects and connects repeatedly during the 2 webservers.
But,when I connect the define webserver,such as
when I set url ="http://xx.xx.xx.xx:5001". It works.
Any way, if we use JavaScript socketio-client in other project,when set url ="http://xx.xx.xx.xx:5000",it works.
So, What should I do?
