Yep, that’s the current behavior of Chrome but I wouldn’t expect it to continue to be the policy in the future. In firefox 4 (if you enable WebSockets in about:config) you will get a warning about the certificate. To approve the certificate you may also have to enter the WebSockets URL in the browser (substitute … Read more
webSockets and regular sockets are not the same thing. A webSocket runs over a regular socket, but runs its own connection scheme, security scheme and framing protocol on top of the regular socket and both endpoints must follow those additional steps for a connection to even be made. You can see the webSocket protocol here: … Read more
WebSocket is, at its heart, just a set of framing for TEXT or BINARY data. It performs no compression on its own. However, the WebSocket spec allows for Extensions, and there have been a variety of compression extensions in the wild (the formalized specs for one of these is finalized). As of today (August 2018) … Read more
Try this: var reconnectInterval = x * 1000 * 60; var ws; var connect = function(){ ws = new WebSocket(‘ws://localhost’); ws.on(‘open’, function() { console.log(‘socket open’); }); ws.on(‘error’, function() { console.log(‘socket error’); }); ws.on(‘close’, function() { console.log(‘socket close’); setTimeout(connect, reconnectInterval); }); }; connect(); You get to use the original implementation without having to wrap it.
I think the cleanest solution would be to change the base64 encoder to operate directly on a Uint8Array instead of a string. Important: You’ll need to set the binaryType of the web socket to “arraybuffer” for this. The onmessage method should look like this: socket.onmessage = function(msg) { var arrayBuffer = msg.data; var bytes = … Read more
WebSockets uses TCP, which is point to point, and provides no broadcast support.
My tool websocat is specifically designed for this. websocat ws://your_server/url You can connect and exchange data with your server. By default each line becomes a WebSocket text message and vice versa. On Linux it is more comfortable to play with it using readline: rlwrap websocat ws://your_server/url. It is not the only CLI websocket client. There … Read more
Scenario 2 talks about, in the last step, a single client.But I thought your requirement was for a topic since you wanted multiple clients. If I wanted to complete 2 for your stated requirement, then you might want to maintain a list of clients and implement your own queue or use a ForkJoinPool to message … Read more
TL; DR: Use ReceiveAsync() in loop until Close frame is received or CancellationToken is canceled. That’s how you get your messages. Sending is straightworward, just SendAsync(). Do not use CloseAsync() before CloseOutputAsync() – because you want to stop your receiving loop first. Otherwise – either the CloseAsync() would hang, or if you use CancellationToken to … Read more
No, websockets is only natively supported by Windows in Windows 8, regardless of which visual studio version you are using. http://www.paulbatum.com/2011/09/getting-started-with-websockets-in.html This is due to some low level issues in Windows 7 with http.sys. There’s an offchance it may be backported, but seems unlikely: http://weblogs.asp.net/owscott/archive/2012/03/01/what-s-new-in-iis-8.aspx To use websockets on Windows 7, you’ll have to write … Read more
