Ruby -尝试使用嵌套的散列遍历散列(在期望JSON对象之后)

def traverse_hash(hash)
  hash.each do |key, value|
    if value.is_a?(Hash)
      traverse_hash(value)  # 递归调用遍历嵌套的散列
    else
      # 处理键值对，例如打印出来
      puts "#{key}: #{value}"
    end
  end
end

# 示例散列
json_object = {
  "name" => "John",
  "age" => 30,
  "address" => {
    "street" => "123 Main St",
    "city" => "New York"
  },
  "hobbies" => ["reading", "swimming"]
}

traverse_hash(json_object)

name: John
age: 30
street: 123 Main St
city: New York
hobbies: ["reading", "swimming"]
