So, for everything to work correctly, it's better to specify explicitly the allowed origins.

## Use `CORSMiddleware`

You can configure it in your **FastAPI** application using the `CORSMiddleware`.

* Import `CORSMiddleware`.
* Create a list of allowed origins (as strings).
* Add it as a "middleware" to your **FastAPI** application.

You can also specify if your backend allows:

URLs are abstract:

   * invocations to {@code handler}. The class loader of {@code interfaceType} will be used to
   * define the proxy class. To implement multiple interfaces or specify a class loader, use {@link
   * Proxy#newProxyInstance}.
   *
   * @throws IllegalArgumentException if {@code interfaceType} does not specify the type of a Java
   *     interface
