Hello
I have node+socket.io :
Code:
[root@socketio]# node -v
v14.18.3
[root@socketio]# npm list socket.io
/var/socketio
└── socket.io@4.4.1
Socket.io server config :
Code:
var fs = require('fs');
var options = {
key: fs.readFileSync('/etc/letsencrypt/live/my.domain.tld/privkey.pem'),
cert: fs.readFileSync('/etc/letsencrypt/live/my.domain.tld/fullchain.pem')
};
var cors = require('cors');
var server = require('https').createServer(options)
var io = require('socket.io')(server, { cors: { origin: true } });
server.listen(port, function(){
console.log('listening on *: '+ port + "\n");
});
On my socket.io-client server I have :
Code:
var io = require('socket.io-client');
var wsServer='https://my.domain.tld:4123';
// Connect to our node/websockets server
var socket = io.connect(wsServer, {
reconnection: true,
reconnectionDelay: 1000,
reconnectionDelayMax : 5000,
reconnectionAttempts: 3
});
I get output :
Code:
connect_error due to xhr poll error
On my Chrome browser I have :
Code:
// Connect to our websocket-server
var socket = io.connect('https://my.domain.tld:4123');
Here I get in my browser :
Code:
Access to XMLHttpRequest at 'https://my.domain.tld:4123/socket.io/?EIO=3&transport=polling&t=NvEIxIV' from origin 'https://mydomain.tld' has been blocked by CORS policy: The value of the 'Access-Control-Allow-Credentials' header in the response is '' which must be 'true' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
When adding more CORS (as I read on stackOverflow) :
Code:
{ cors: { origin: true, credentials: true } }
I get :
Code:
GET https://my.domain.tld:4123/socket.io/?EIO=3&transport=polling&t=NvEJVnb 400 (Bad Request)
Again I add more CORS (as I read on the internet) :
Code:
cors: { origin: true, credentials: true, methods: ["GET", "POST"], transports: ['websocket', 'polling'] } }
Still I get in my Chrome browser :
Code:
GET https://my.domain.tld:4123/socket.io/?EIO=3&transport=polling&t=NvEJVnb 400 (Bad Request)
And on my socket.io-client server :
Code:
connect_error due to xhr poll error
So what am I missing here ??
