解析Node中的嵌套api响应

Question

一个如下的API请求：const response = await this.publicGetMarkets (params);给了我一个响应，其中包含以下格式的markets列表：

{
  "markets": {
    "LINK-USD": {
    "market": "LINK-USD",
    "status": "ONLINE"
  },
  ...
}

就像这里的例子一样，我的问题是每个市场的LINK-USD都在变化。我如何修复我的代码，使我可以在我的代码中的变量，如market，status。我已经编写了以下代码片段：

const market = this.safeValue (response, 'markets');
    const result = [];
    for (let i = 0; i < markets.length; i++) {
       const markets = this.safeString (markets, {}, {});
       const market = this.safeString (markets, 'market');
       const status = this.safeString (markets, 'status');
       result.push({
           'market': market,
           'status': status,
        });
     }
     return result;

Answer 1

您可以使用Object.values(data.markets)获取所有内部对象的数组。

如果需要过滤掉不需要的属性，这也是一个相当简单的映射

​

const data = {
  "markets": {
    "LINK-USD": {
      "market": "LINK-USD",
      "status": "ONLINE"
    },
    "LINK-EURO": {
      "market": "LINK-EURO",
      "status": "TBD"
    }
  }
}

const res = Object.values(data.markets)

console.log(res)

Answer 2

    const responses = this.safeValue (response, 'markets');
    const result = [];
    for (let response of responses) {
       const market = responses.markets["LINK-USD"].market,
       status = responses.markets["LINK-USD"].status;
       result.push({market, status});
     }
     return result;

我希望这就是你要的。
