仅限Linux:
```go
package main
func main() {
pwd = new(string)
terminalEcho(false) // Hide input
fmt.Scanln(pwd)
terminalEcho(true)
fmt.Println(pwd)
}
func terminalEcho(show bool) {
// Enable or disable echoing terminal input. This is useful specifically for
// when users enter passwords.
// calling terminalEcho(true) turns on echoing (normal mode)
// calling terminalEcho(false) hides terminal input.
var termios = &syscall.Termios{}
var fd = os.Stdout.Fd()
if _, _, err := syscall.Syscall(syscall.SYS_IOCTL, fd,
syscall.TCGETS, uintptr(unsafe.Pointer(termios))); err != 0 {
return
}
if show {
termios.Lflag |= syscall.ECHO
} else {
termios.Lflag &^= syscall.ECHO
}
if _, _, err := syscall.Syscall(syscall.SYS_IOCTL, fd,
uintptr(syscall.TCSETS),
uintptr(unsafe.Pointer(termios))); err != 0 {
return
}
}
```
