# Веб-сокеты

Вы можете использовать <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">веб-сокеты</a> в **FastAPI**.

## Установка `WebSockets`

Убедитесь, что [виртуальная среда](../virtual-environments.md){.internal-link target=_blank} создана, активируйте её и установите `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

   * object behaves appropriately when its thread is interrupted.
   *
   * <p>For example, to return the value of {@code target.someMethod()}, but substitute {@code
   * DEFAULT_VALUE} if this method call takes over 50 ms, you can use this code:
   *
   * <pre>
   *   TimeLimiter limiter = . . .;
   *   TargetType proxy = limiter.newProxy(
   *       target, TargetType.class, 50, TimeUnit.MILLISECONDS);

## Dokumentations-Tags – OpenAPI

Um Tags zu Ihren *Pfadoperationen* hinzuzufügen und diese in der Oberfläche der Dokumentation zu gruppieren, lesen Sie die Dokumentation unter [Tutorial – Pfadoperation-Konfiguration – Tags](../tutorial/path-operation-configuration.md#tags){.internal-link target=_blank}.

## Zusammenfassung und Beschreibung in der Dokumentation – OpenAPI

        JobLog jobLog = new JobLog();
        jobLog.setId("test-log-1");
        jobLog.setJobName("Test Job");
        jobLog.setEndTime(null);

        MonitorTarget target = new MonitorTarget(jobLog);
        try {
            target.expired();
            // If it succeeds, check that lastUpdated is set
            assertNotNull(jobLog.getLastUpdated());
        } catch (Exception e) {

proprietary headers can be added <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">using the 'X-' prefix</a>.

But if you have custom headers that you want a client in a browser to be able to see, you need to add them to your CORS configurations ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}) using the parameter `expose_headers` documented in <a href="https://www.starlette.io/middleware/#corsmiddleware"...

        this.targetClass = targetClass;
        this.methodName = methodName;
        this.methodArgClasses = methodArgClasses;
    }

    /**
     * Returns the {@link Class} of the target.
     *
     * @return {@link Class} of the target
     */
    public Class<?> getTargetClass() {
        return targetClass;
    }

    /**
     * Returns the method name.
     *
     * @return Method name
