Ruby有条件的问题？

Question

我有这样的代码：

def name_of_client 
    puts "Hello sir/madam; please enter your name: " 
    name = gets.chomp.upcase 
    puts "Welcome to the Great Bank, #{name}. Would you like to enter your seriously insecure account? (Y/N)" 
end 

def get_response 
    answer = gets 
    if answer == "Y" || answer == "y" 
    puts 'Sure thing... ' 
    elsif answer == "N" || answer== "n" 
    puts "Logging you out now. " 
    end 
end 

name_of_client 
get_response 

为什么当我输入"Y"或"N"的字符串不打印？

Answer 1

gets向answer变量添加新行。改为使用gets.chomp或gets.strip。在将来，我会推荐使用pry gem，如下所示，它暂停执行，就像调试器在javascript中一样。要安装pry，请打开终端窗口（假设您正在运行linux或macOS）并运行gem install pry。您可以使用它，如下所示。

require "pry" 

def get_response 
    answer = gets.strip 
    binding.pry 
    if answer == "Y" || answer == "y" 
     puts 'Sure thing... ' 
    elsif answer == "N" || answer== "n" 
     puts "Logging you out now. " 

    end 
end 

get_response
