使用相同的处理程序处理websocket和HTTP

Question

Been scouring for a while but couldn't find anything that directly answers this.

Can Go handle WS connections and HTTP connections using the same handler?

In short, I'd like to replicate something like SignalR

Yes, the gorilla/websocket package supports upgrade from HTTP to WebSocket in a request handler. See the example at the beginning of the package documentation. The function handler is a standard HTTP request handler. The call to upgrader.Upgrade switches the connection to the WebSocket protocol.

The x/net/websocket package requires a separate handler. There are other reasons why you probably don't want to use the x/net/websocket package.
