Javascript 如何使用map函数在React.js上显示键到组件上有空格的json

我正在尝试使用股票市场的API，所以当表单提交并收到下面的JSON文件时，我会调用API，并将其值存储在钩子上

    "Meta Data": {
        "1. Information": "Daily Prices (open, high, low, close) and Volumes",
        "2. Symbol": "IBM",
        "3. Last Refreshed": "2020-12-04",
        "4. Output Size": "Compact",
        "5. Time Zone": "US/Eastern"
    },
    "Time Series (Daily)": {
        "2020-12-04": {
            "1. open": "123.9700",
            "2. high": "127.3800",
            "3. low": "123.6400",
            "4. close": "127.2000",
            "5. volume": "5522760"
        },
        "2020-12-03": {
            "1. open": "124.1600",
            "2. high": "124.8600",
            "3. low": "123.2900",
            "4. close": "123.6100",
            "5. volume": "4548161"
        }
}

所以我创建了两个简单的组件：StockList和StockItem，StockList用于呈现所有StockItem，我无法访问StockItem中JSON的值，因为我不知道如何显示键上有空格的数据。通常JSON是这样的：

  {
    "id": 1,
    "name": "Leanne Graham",
    "username": "Bret",
    "email": "Sincere@april.biz",
    "address": {
      "street": "Kulas Light",
      "suite": "Apt. 556",
      "city": "Gwenborough",
      "zipcode": "92998-3874",
      "geo": {
        "lat": "-37.3159",
        "lng": "81.1496"
      }
    }

users.map((user) => {
   return(
     <p>{user.name}</p>
     <p>{user.username}</p>
   )
});

使用以下地图很容易显示：

  {
    "id": 1,
    "name": "Leanne Graham",
    "username": "Bret",
    "email": "Sincere@april.biz",
    "address": {
      "street": "Kulas Light",
      "suite": "Apt. 556",
      "city": "Gwenborough",
      "zipcode": "92998-3874",
      "geo": {
        "lat": "-37.3159",
        "lng": "81.1496"
      }
    }

users.map((user) => {
   return(
     <p>{user.name}</p>
     <p>{user.username}</p>
   )
});

users.map（（用户）=>{
返回(
{user.name}

{user.username}

)
});

---

当我试图使用map来解决这个问题时，我得到了未定义的属性。

来访问键上有空格的数据

user['key'] => 

example : user['first name']

let a={“first name”：“dileep”}；
log（a['first name']）

user['key']=>example:user['first name']，试试这个让我知道例如，让a={“first name”：'dileep'}；a[“名字”]让我知道它是否对你有帮助
