无法读取超过1个水平上的JSON

所以我做了这个JSON文件...

{ 'Blue Aces Bakery':
{ Symbol: 'BAB',
 Stock:
  { onSale: {},
    Shares: 13,
    Price: 10,
    marketCap: 130,
    Balance: 10075,
    stockOpen: 10,
    previousClose: 10,
    chartFile: './public/BAB',
    Intraday: [Array],
    previousIntraday: [Array] 
    } 
    } 
}

但是，当我运行此代码

var stockData = require('./stocks.json');
console.log(stockData[Companies])
if(stockData[Companies].Stock.onSale.Bids) {...

我得到这个：

{ 'Blue Aces Bakery':
{ Symbol: 'BAB',
 Stock:
  { onSale: {},
    Shares: 13,
    Price: 10,
    marketCap: 130,
    Balance: 10075,
    stockOpen: 10,
    previousClose: 10,
    chartFile: './public/BAB',
    Intraday: [Array],
    previousIntraday: [Array] } } }

  (node:14680) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'onSale' of undefined
at checkStocks (C:\Users\Mark\Desktop\Stock Bot\base.js:30:39)

这使得零道理给我。有人可以帮助我，我做错了什么在这里？我已经尝试过寻找它，并没有其他人似乎有同样的问题。

console.log()只显示深对象的几级。

您将要使用console.dir()（取决于版本等）或util.inspect()。

演示：

$ node 
> let a = {}; a.b = {}; a.b.c = {}; a.b.c.d = {}; a.b.c.d.e = [0,1,2,3,4];
[ 0, 1, 2, 3, 4 ]
> console.log(a)
{ b: { c: { d: [Object] } } }
undefined
> console.dir(a)
{ b: { c: { d: [Object] } } }
undefined
> console.log(util.inspect(a, false, null, true))
{ b: { c: { d: { e: [ 0, 1, 2, 3, 4 ] } } } }
undefined
> process.version
'v10.14.1'
