How to access Websocket Response Headers in Javascript?

问题

I need to access the response header from a javascript websocket connection. Is there any way to access these response header? Or at least the response code?

I only have access to the event of onclose, onerror, onopen with a few (unusable - for my purposes) properties!

回答1:

You can't. There is no functionality for that at the moment. The point of WebSockets is not HTTP communication. HTTP is only used for the handshake.
