我是go和websocket的新手。我试图逐个输入字符并将其写入websocket。我什至要以ctrl + c作为输入并将其写入websocket。

func (c *poc) writePump() {

    var err error

    exec.Command("stty", "-F", "/dev/tty", "cbreak", "min", "1").Run()
    exec.Command("stty", "-F", "/dev/tty", "-echo").Run()
    defer exec.Command("stty", "-F", "/dev/tty", "echo").Run()

    var b = make([]byte, 1)
    d := make(chan os.Signal, 1)
    signal.Notify(d, os.Interrupt)

    for {
        os.Stdin.Read(b)
        err = c.ws.WriteMessage(websocket.TextMessage, b)
        if err != nil {
            log.Printf("Failed to send UTF8 char: %s", err)
        }

        go func() {
            for sig := range d {
                // ????
            }
        }()
    }
}

此代码正在捕获信号，但不确定如何写入websocket。
