When you raise an exception, as would happen with normal Python, the rest of the execution is aborted. This way you can raise these exceptions from anywhere in the code to abort a request and show the error to the client.

You can use:

* `HTTPException`
* `WebSocketException`

These exceptions can be imported directly from `fastapi`:

```python

          try {
            bytesRead = source.read(sink, byteCount)
          } catch (e: IOException) {
            if (!cacheRequestClosed) {
              cacheRequestClosed = true
              cacheRequest.abort() // Failed to write a complete cache response.
            }
            throw e
          }

          if (bytesRead == -1L) {
            if (!cacheRequestClosed) {
              cacheRequestClosed = true

		resp.headers['x-amz-request-token'] = request_token
		return resp

	else:
		abort(400)

if __name__ == '__main__':
	app.run()
```
