Binary-Data over WebSockets not supported?

[Clemens]

Hi,

I try to receive binary data using WebSockets, my code basically looks
like this:

webSocket = new WebSocket('ws://.......');
webSocket.binaryType = "arraybuffer";
webSocket.onmessage = function(e) {
.... = new Uint8Array(e.data);
}

However chrome just prints out the following message:
> "Received a binary frame which is not supported yet."

Does chrome (14) not support binary data over websockets, or is this
my fault?

Thank you in advance, Clemens

Chrome 14 does not support the transmission of binary data over WebSocket just yet.

This (along with other new features of the latest -10 draft) is being actively developed. I am not sure Chrome 15 will have it, I guess Chrome 16 is more likely.

No official time frame.

Thanks for the clarification. Well seems I have to rely on Base64
again.
Hopefully the whole websocket-topic will be settled soon, its has been
going on for sooo lang already :/

Thanks, Clemens

Well better to say "we thank you" :)
I've just downloaded the build and tried to receive fragmented blob
imsge, fragmented arraybuffer image and send image to server.... all
works!!

Thumbs UP!

I'm on Chrome 22.0.1229.79 on OS X 10.8

I am attempting to send binary data up to javascript in Chrome.  

        ws = new WebSocket(url);

        ws.binaryType = "arraybuffer";

I put a debugger; in my ws.onmessage, and it is never hit.

On the console I read

" Could not decode a text frame as UTF-8. "

which is printed in my ws.onerror function.

From everywhere I've read this has been supported in Chrome for some time.  Can anyone let me know what I am missing?

thanks

The message opcode was being set to Text.  I set to Binary and we are all good.  Sorry for the spam.

Hi Lucas,

To get a better response, you should give more information.

Assuming this code is on client side, are you sure the server side supports binary frame?

ws.binaryType = "arraybuffer";

This defines your preference of format you will receive binary data in (arraybuffer or blob). So this doesn't indicate the format of the binary data you are going to send. In case you don't know.

I have an audio streaming demo code which sends audio data as binary.

Check out this part:

Here's the live demo:
