Question

我无法从JSON文件中获取值，该文件已从Steam API（http://steamcommunity.com/dev）中检索到。

当我尝试打印数据时出现问题，Node.js文件代码如下：

var data = JSON.parse(body); // Stores the JSON data which has been retrieved
console.log(data.result.toString(350462890).market_hash_name); // Attempts to grab the value of the market_hash_name from the JSON data and display it to screen

我收到以下回复：＆＃34; undefined＆＃34;。

以下使用的JSON数据：

        },
        "classid": "350462890"
    },
    "success": true
}

}

那么有谁知道如何返回market_hash_name？另请注意，我是使用Node.js的新手。
