如何从 API 获取数据，其中 stream 实时数据

Question

我想在这里使用这个 API，

https://developer.sportradar.com/docs/read/basketball/NCAA_Mens_Basketball_v7#tournament-summary-seed-tournaments-only

此端点检索每个游戏事件的详细实时信息。 我正在尝试在节点 JS 中实现这一点。 我怎样才能做到这一点？ 每当我们点击它时，这个 API 都会重定向到不同的 URL。 有什么办法可以从中解析数据吗？ 它返回这样的响应，

{

      "interval":5000
   }

Answer 1

您可以使用间隔从 API 获取数据，然后将数据传递给 websocket 服务器

Answer 2

如果事件由您的 API 触发，则为事件源。https://developer.mozilla.org/en-US/docs/Web/API/EventSource
