cors error
GonnaWooh opened this issue · comments
I want to connect client web page for socketIO and admin-ui to socketIO server.
But the error appears.
When I use this code below, the client web disconnects with cors error.
const io = new Server(httpServer, {
cors: {
origin: "https://admin.socket.io",
},
});
instrument(io, {
auth: false,
});
Of course, I did like this, and "xhr poll error" happens on admin-ui.
const io = new Server(httpServer, {
cors: {
origin: "", // and I did ["https://admin.socket.io",""] instead of this
},
});
instrument(io, {
auth: false,
});
does admin-ui supports only local environment?
It seems you are missing the credentials: true
part:
const { createServer } = require("http");
const { Server } = require("socket.io");
const { instrument } = require("@socket.io/admin-ui");
const httpServer = createServer();
const io = new Server(httpServer, {
cors: {
origin: ["https://admin.socket.io"],
credentials: true
}
});
instrument(io, {
auth: false
});
httpServer.listen(3000);

Could you please check?

My mistake. The line "credentials: true" is not there, but I wrote it already.
@GeonwooDev have you eventually found a solution?
@darrachequesne No, I'm not using admin-ui, but only socketIO.
any updates on this?
@MehdiMamas unfortunatly I am not able to reproduce the issue.
From my understanding there are two possible explanations:
- either the
cors
configuration is incorrect (which does not seem to be the case here) - or the UI is not able to reach the Socket.IO server
Could you please share what gets printed to the console?
did you find the answer
Getting error as well.
I have added a few examples in the documentation about the cors
option: https://socket.io/docs/v4/server-options/#cors
Does that help?
same issue here.
even with origin: "*"
im getting GET http://localhost:8080/socket.io/?EIO=4&transport=polling&t=Oyga8kN net::ERR_FAILED 404 (Not Found)
I have also tried everything in this thread, to no avail.
Same issue
