如何在 ionic 应用程序中显示股票价格的实时变化
我有一个第 3 方 api https://api.twelvedata.com/time_series?symbol=TEST_SYMBOL&interval=1day&apikey=YOUR_API_KEY 我已在卡片中显示股票价格表。现在我必须显示每张卡每秒变化的实时数据我该怎么做。 我尝试了很多方法，但整个 api 都被获取，而不是更新单张卡的数据。

是的，提供的api支持websocket配置。但如果加载了 api，它不会改变价格，我必须刷新浏览器并检查价格变化
Yes, the api provided supports websocket configuration. but if the api is loaded it does not change price i have to refresh the browser and check the price change
