addRoom(): Observable<any> {
    const headers = new HttpHeaders()
      .set("content-type", "application/json")
      .set("Access-Control-Allow-Origin", "http://localhost:8000")
      .set("Access-Control-Allow-Methods", "GET,POST,PATCH,DELETE,PUT,OPTIONS")

Access to XMLHttpRequest at 'https://sambhav.daily.co/v1/rooms' from origin 'http://localhost:8000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

来自 Daily 的 Phil 在这里。

我认为问题在于您的请求的基本 URL。所有 REST API 调用都使用https://api.daily.co/v1/

因此，在您的情况下，您想将 POST 发送到https://api.daily.co/v1/rooms.

如果文档不清楚，请告诉我。我们现在正在改造它们，您的意见很有价值。

我还建议刷新您的 API 密钥，因为您已将其包含在上面。
