JSON数据看起来像这样

[
    {
        "market_id": "21",
        "coin": "DarkCoin",
        "code": "DRK",
        "exchange": "BTC",
        "last_price": "0.01777975",
        "yesterday_price": "0.01770278",
        "change": "+0.43",
        "24hhigh": "0.01800280",
        "24hlow": "0.01752015",
        "24hvol": "404.202",
        "top_bid": "0.01777975",
        "top_ask": "0.01790000"
    }
]

注意这里有3个属性24high,24hhlow和24hvol你如何为它做一个类.顺便提一下,我需要所有这些属性,而不仅仅是我提到的那三个属性.
