I send an array from rest client and received it like this: "[1,2,3,4,5]"
我从休息客户端发送一个数组并收到它：“[1,2,3,4,5]”
Now I just want to convert it into Array without using Ruby's eval method. Any Ruby's default method that we could use for this?
现在我只想将它转换为Array而不使用Ruby的eval方法。我们可以使用任何Ruby的默认方法吗？
"[1,2,3,4,5]" => [1,2,3,4,5]

require 'json'
JSON.parse "[1,2,3,4,5]"
#=> [1, 2, 3, 4, 5]
JSON.parse "[[1,2],3,4]"
#=> [[1, 2], 3, 4]

If you want to avoid eval, yet another way:
如果你想避免使用eval，还有另一种方法：
"[1,2,3,4,5]".scan(/\d/).map(&:to_i) #assuming you have integer Array as String
#=> [1, 2, 3, 4, 5]
