开始抢救重试错误

Question

如果此代码执行else语句，我希望它从rescue或begin重试。 运行代码会要求我输入，而当我输入代码时，代码将不起作用。

1-如何使此代码与运行retry的else语句一起工作？

2-为什么取消rescue retry Syntax Error ？

# Creates input method
def input
  x = gets.to_i
end

#Begins the first choice
begin

  puts "What will you do?
  1- Get a closer look
  2- Go in the opposite direction
  Write your input an press enter:"
rescue
  #Calls input method
  choice = input
  if choice == 1
    puts "You get a closer look and..."
  elsif choice == 2
    puts "You go in the opposite direction, out of trouble"
  else 
    puts "Incorrect input, enter a number between the one's avaliables:"
  end

  #Retries if the choice is error
retry if choice != 1||2
end

Answer 1

使用抢救块用于处理异常，我真的认为这里不需要它。 循环将完成工作。

puts "What will you do?",
     "1- Get a closer look",
     "2- Go in the opposite direction",
     "Write your input and press enter:"

loop do
  choice = gets.to_i
  if choice == 1
    puts "You get a closer look and..."
    break
  elsif choice == 2
    puts "You go in the opposite direction, out of trouble"
    break
  else
    puts "Incorrect input, enter a number between the ones available:"
  end
end
