Ruby $stdin.gets 在屏幕上不显示字符 [英] Ruby $stdin.gets without showing chars on screen

问题描述

我想要求用户输入密码，但我不希望字符在他们输入时出现在屏幕上.

I want to ask users to type in a password, but I don't want the chars to appear on screen as they type.

如何在 Ruby 中执行此操作?

How do I do this in Ruby?

推荐答案

这种用户交互有一个宝石:高线.

There is a gem for such user interaction: highline.

password = ask("Password:  ") { |q| q.echo = false }

甚至:

password = ask("Password:  ") { |q| q.echo = "*" }
