Your Client <https://play.golang.org/p/CmXjfAJSCY7> code does not compile. As a courtesy to those trying to help, it is always good to test your code before posting it. A working example, without your "busy" messages would be something like: https://play.golang.org/p/cvgwd8GDobc . The Read() method documentation <https://godoc.org/golang.org/x/net/websocket#Conn.Read> says "Read implements the io.Reader interface." So I suggest you *carefully *read the io.Reader documentation <https://golang.org/pkg/io/#Reader>, because it requires very specific handling to be done correctly.
Also, I did note that golang.org/x/net/websocket documentation <https://godoc.org/golang.org/x/net/websocket> states that: "This package currently lacks some features found in alternative and more actively maintained WebSocket packages." So you may want to consider using one of those. I have not actually used golang.org/x/net <https://godoc.org/golang.org/x/net>/websocket myself, but there is a SetReadDeadline <https://godoc.org/golang.org/x/net/websocket#Conn.SetReadDeadline>() function. Because I have not used the package before, there may be some hidden pitfalls that I am missing, but this code seems to do what you want, using SetReadDeadline <https://godoc.org/golang.org/x/net/websocket#Conn.SetReadDeadline>(): https://play.golang.org/p/ISUR7c_Mtqb Good luck On Wednesday, March 25, 2020 at 8:56:57 PM UTC-4, 洪嘉鴻 wrote: > > I'm sorry. > The followings are the complete codes of server and client: > Server <https://play.golang.org/p/9vu0GW5a5Y8> > Client <https://play.golang.org/p/CmXjfAJSCY7> > > Thank you very much! > Max > > Jake Montgomery於 2020年3月25日星期三 UTC+8下午9時28分37秒寫道： >> >> You do not provide enough information to give a really good answer.
