这是我正在使用的文本文件的内容：
[{"name": "Bitcoin", "symbol": "BTC", "rank": 1, "slug": "bitcoin", "tokens": ["Bitcoin", "bitcoin", "BTC"], "id": 1},
{"name": "Ethereum", "symbol": "ETH", "rank": 2, "slug": "ethereum", "tokens": ["Ethereum", "ethereum", "ETH"], "id": 1027}, ... ]
如何检索每个＆＃34;名称＆＃34;每个硬币的元素并将其保存为临时变量？

如果您习惯使用第三方库，class Pizza
attr_reader :topping
# I had to add the name in the initializer for better error reporting.
Toppings = Enum.new('Toppings') do
option(:pepperoni).set("Pepperoni")
option(:sausage).set("Sausage")
option(:mushrooms).set("Mushrooms")
end
def set_topping(symbol)
@topping = Toppings[symbol]
end
end
pizza = Pizza.new
### Happy Case
pizza.set_topping(:pepperoni)
#=> "Pepperoni"
### Sad Case (Error message shown below is what I'm trying to figure out)
pizza.set_topping(:spinach)
#=> RuntimeError: Option Toppings::spinach not found.
