從JSON獲取值，Node.js

我在從Steam API（http://steamcommunity.com/dev）中檢索到的JSON文件內部獲取值時遇到了問題。從JSON獲取值，Node.js

的問題，當我試圖打印數據時，Node.js的文件代碼如下：

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

我得到如下回應：「未定義」。下面使用

JSON數據：

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

}

因此，沒有人有任何想法，我怎麼可以返回market_hash_name？也請注意，我對使用Node.js相當陌生。

請注意，您不需要將數字轉換爲字符串。傳遞一個數字也可以 – slebetman
