arrays - 将字符串化键值对数组转换为 Ruby 中的哈希

Question

我在数组中有一些键值对字符串:

array = [ "Name = abc", "Id = 123", "Interest = Rock Climbing" ]

我需要将其转换为散列:

hash = { "Name" => "abc", "Id" => "123", "Interest" => "Rock Climbing" }

我一定是做错了什么，因为我的 .shift.split 得到了奇怪的映射，导致 {"Name=abc"=>"Id=123"}.

Answer 1

您需要做的就是将数组的每个部分拆分为键和值(产生一个双元素数组)，然后将结果传递给方便的 Hash[] 方法:

arr = [ "Name = abc", "Id = 123", "Interest = Rock Climbing" ]

keys_values = arr.map {|item| item.split /\s*=\s*/ }
# => [ [ "Name", "abc" ],
#      [ "Id", "123" ],
#      [ "Interest", "Rock Climbing" ] ]

hsh = Hash[keys_values]
# => { "Name" => "abc",
#      "Id" => "123",
#      "Interest" => "Rock Climbing" }
