Gorilla WebSocket与golang.org/x/net/websocket的比较

According Gorilla Websockets Project it is not possible to send pings and pongs using golang.org/x/net/websocket. At the same time, the following is on the project page of golang.org/x/net/websocket:

Package websocket implements a client and server for the WebSocket protocol as specified in RFC 6455.

I am a little confused. golang.org/x/net/websocket implements RFC 6455 but can not send control frames (cancel, ping, pong) although this is specified in RFC 6455 - Section Control Frames

So what will happen if I use golang.org/x/net/websocket package. Will the connection abort after a timeout? In other words, how is it ensured here that the connection does not break off.

    The Gorilla README says something different. It says that the golang.org/x/net package cannot send a ping or receive a pong. It does not say that the package will not send a pong.

    The golang.org/x/net package automatically responds to a ping received from the peer by sending a pong to the peer, as does the Gorilla package. Both packages work correctly with a peer that's using ping and pongs to keep the connection alive.

    An application that uses the golang.org/x/net/websocket package cannot employ pings and pongs to keep the connection alive. There's no way to send the ping. There's no way to detect that the pong was received.
