如何从 Ruby 的命令行读取密码?

问题描述

我在 Windows 机器上运行 Ruby 和 MySQL.

I am running Ruby and MySQL on a Windows box.

我有一些 Ruby 代码需要连接到 MySQL 数据库并执行选择.要连接到数据库，我需要提供密码等.

I have some Ruby code that needs to connect to a MySQL database a perform a select. To connect to the database I need to provide the password among other things.

Ruby 代码可以显示要求输入密码的提示，用户输入密码并按 Enter 键.我需要的是输入的密码显示为一行星号.

The Ruby code can display a prompt requesting the password, the user types in the password and hits the Enter key. What I need is for the password, as it is typed, to be displayed as a line of asterisks.

如何让 Ruby 将键入的密码显示为dos 框"中的一行星号?

How can I get Ruby to display the typed password as a line of asterisks in the 'dos box'?

推荐答案

为了回答我自己的问题，并为了其他想知道的人的利益，有一个名为 HighLine 你需要的.

To answer my own question, and for the benefit of anyone else who would like to know, there is a Ruby gem called HighLine that you need.

require 'rubygems'
require 'highline/import'

def get_password(prompt="Enter Password")
   ask(prompt) {|q| q.echo = false}
end

thePassword = get_password()
