ruby - 如何转换 Ruby 哈希，使其所有键都是字符串

Question

我有一个 ruby​​ 散列，它看起来像:

{ id: 123, name: "test" }

我想将其转换为:

{ "id" => 123, "name" => "test" }

Answer 1

如果您使用的是 Rails 或 ActiveSupport:

hash = { id: 123, description: "desc" }
hash.stringify #=> { "id" => 123, "name" => "test" }

如果你不是:

hash = { id: 123, name: "test" }
Hash[hash.map { |key, value| [key.to_s, value] }] #=> { "id" => 123, "name" => "test" }
