    return
end

err = c:write_text("hello")
if err then
    print(err)
    return
end

local msg_type, msg
msg_type, msg, err = c:read()
if err then
    print(err)
    return
end

print(string.format("receive a message, msg_type: %d, msg: %s", msg_type, msg))

err = c:ping("ping")

Manual Test

You can use this Websocket Echo Server to start a websocket server

Then you can use this demo to test your lua file

package main

import (
	"github.com/Root-lee/gluawebsocket"
	lua "github.com/yuin/gopher-lua"
)

func main() {
	L := lua.NewState()
	gluawebsocket.Preload(L)
	defer L.Close()

	if err := L.DoFile("test.lua"); err != nil {
		panic(err)
	}
}

You can refer to this lua script to write your own lua script
