My websocket connection is working completely fine in http.But the message is not showing in https.Can anyone give me a better solution
.I am getting like this.
I am trying to make a connection to a socket.io session. The connection is easily established, however, if I am idle for a short duration I get this error in my console:
websocket.js:116 WebSocket connection to 'ws://localhost:3000/socket.io/?EIO=3&transport=websocket&sid=PwzuR5tNmPmZfj0UAAAB' failed: WebSocket opening handshake timed out
I tried fixing the issue by setting pingTimeout and pingInterval but to no avail. I am not sure how to fix this or what is causing this.
On a side note, I am trying to read and understand the socket.io docs and am still not clear about what ping and pong packets exactly are. Does the client have to manually interact with the socketio server in order for it to receive pong packets or will it still receive pongs if say the client interacts with an http server on the same host ?
I use PJNATH to connect with webrtc datachannele. It can send and receive data now. But i don't known when the other peer disconnect. Although I can check connecton disconnect by heartbeat in application layer,but i think it not the best choice. Is anyone who familiar with PJNATH can give me some suggest?
thanks~
We are trying to disconnect websocket connection from server side and it seems this enhancement is done as part of https://jira.spring.io/browse/SPR-12288. I am not able to find exactly what change we need to implement w.r.t. the same. We are using ChannelInterceptorAdapter to handle the requests.
I'm trying to write a server for a webSocket connection. I've read the spec (76, not 75) carefully. I'm using minefield as the browser.
When I try to create a WebSocket from javascript in the browser:
var ws = new WebSocket("ws://localhost:8766/hoho");
The browser responds with
"Firefox can't establish a connection to the server at ws://localhost:8766/hoho."
My server is getting a valid client handshake request, it sends back the response and then boom.
I've run every example handshake example I can find through my server and I match the given responses exactly in every instance. I'm pretty confident that the return byte stream is correct. I don't need help debugging my code, it's doing what I mean it to do. I need help debugging my use of the handshake protocol since when I give minefield what I think is a correct response it laughs at me.
My question is this: How can I debug this thing? I can think of two possibilities.
Is there any way to get minefield to tell me WHY it's rejecting my handshake?
Is there a working, public, webSocket server service on the web? If there is, I can proxy it, watch the byte streams in both direction and figure out where mine is different.
Does anyone have any ideas in these directions or any other ideas?
Thanks for any help.
I'm in the process of debugging a similar situation, and the tool I'm relying on most is netcat, with some additional use of openssl. Shut down your websocket server and run nc -l 8766. That lets you record exactly what headers are being sent. Turn the websocket server back on and use nc 8766 to paste in those same headers and see the result. openssl s_client -connect localhost:443 will let you make the request with ssl, if that is in your mix.
From there, make sure the responses conform completely to the websocket handshake protocol. For instance, my problem right now is that my responses have Connection: close, which is no good.
About the 2nd possibility.
Yes, there is a websocket server out there.
the jWebSocket demo server at http://jwebsocket.org/demos/chat/chat.htm
hope this helps
Added: Echo socket server at: http://www.websocket.org/echo.html
Here's a jsfiddle that I made from http://www.websocket.org echo websocket server which works in Chrome but not in Firefox 6: http://jsfiddle.net/awDLc/
It is adjusted to use MozWebSocket rather than WebSocket, but perhaps that isn't enough?
