Oder Sie haben andere Möglichkeiten, mit dem WebSocket-Endpunkt zu kommunizieren.

---

Für dieses Beispiel verwenden wir jedoch ein sehr einfaches HTML-Dokument mit etwas JavaScript, alles in einem langen String.

Das ist natürlich nicht optimal und man würde das nicht in der Produktion machen.

In der Produktion hätten Sie eine der oben genannten Optionen.

Либо у вас может быть любой другой способ взаимодействия с WebSocket-эндпоинтом.

---

Но для этого примера мы воспользуемся очень простым HTML‑документом с небольшим JavaScript, всё внутри одной длинной строки.

Конечно же, это неоптимально, и вы бы не использовали это в продакшн.

В продакшн у вас был бы один из вариантов выше.

// array position can be safely represented inside a JSON string, embedded
// inside of HTML <script> tags, without any additional escaping.
//
// All values are true except for the ASCII control characters (0-31), the
// double quote ("), the backslash character ("\"), HTML opening and closing
// tags ("<" and ">"), and the ampersand ("&").

# Common functions for EC2 build scripts

# This scripts detects builds running on EC2 by accessing the special ip 169.254.169.254 exposed by AWS instances.
# https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html
exit_if_not_on_ec2_instance() {
  curl -m 1 -s "http://169.254.169.254/latest/meta-data/instance-id"
  IS_EC2_INSTANCE=$?
  if [ $IS_EC2_INSTANCE -ne 0 ]; then

In this example, it would convert the Pydantic model to a `dict`, and the `datetime` to a `str`.

The result of calling it is something that can be encoded with the Python standard <a href="https://docs.python.org/3/library/json.html#json.dumps" class="external-link" target="_blank">`json.dumps()`</a>.

## API Response

XML response for this API is similar to [AWS STS AssumeRoleWithWebIdentity](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html#API_AssumeRoleWithWebIdentity_ResponseElements)

## Example request and response

Sample request with `curl`:

```sh

    }
  }

  companion object {
    /**
     * The cipher suite used during TLS connection fallback to indicate a fallback. See
     * https://tools.ietf.org/html/draft-ietf-tls-downgrade-scsv-00
     */
    const val TLS_FALLBACK_SCSV = "TLS_FALLBACK_SCSV"
  }

	return subtle.ConstantTimeCompare([]byte(sig1), []byte(sig2)) == 1
}

// doesPolicySignatureMatch - Verify query headers with post policy
//   - http://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-HTTPPOSTConstructPolicy.html
//
// returns ErrNone if the signature matches.
func doesPolicySignatureV4Match(formValues http.Header) (auth.Credentials, APIErrorCode) {
	// Server region.
	region := globalSite.Region()
