## Fijar la versión de `fastapi`

Lo primero que debes hacer en tu proyecto es "fijar" la última versión específica de **FastAPI** que sabes que funciona bien con tu aplicación.

Por ejemplo, digamos que estás usando la versión `0.45.0` en tu aplicación.

Si usas el archivo `requirements.txt` puedes especificar la versión con:

```txt
fastapi==0.45.0
```

esto significa que usarás específicamente la versión `0.45.0`.

import java.net.UnknownHostException
import okhttp3.Dns.Companion.SYSTEM

/**
 * A domain name service that resolves IP addresses for host names. Most applications will use the
 * [system DNS service][SYSTEM], which is the default. Some applications may provide their own
 * implementation to use a different DNS server, to prefer IPv6 addresses, to prefer IPv4 addresses,
 * or to force a specific known IP address.

	configMu.RLock()
	defer configMu.RUnlock()

	return opts.ExpirationWorkersWait

// ReplicationWait returns the duration for which a batch replication worker
// would wait before working on next object.
func (opts Config) ReplicationWait() time.Duration {
	configMu.RLock()
	defer configMu.RUnlock()

	return opts.ReplicationWorkersWait
}

 *    number of prefixes (`us-west.www.publicobject.com`, `www.publicobject.com`) including no
 *    prefix at all (`publicobject.com`). For most applications this is the best way to configure
 *    certificate pinning.
 *
 *  * **Exactly one subdomain**: Use a single asterisk like `*.publicobject.com` to match exactly

# WSGI inkludieren – Flask, Django und andere

Sie können WSGI-Anwendungen mounten, wie Sie es in [Unteranwendungen – Mounts](sub-applications.md){.internal-link target=_blank}, [Hinter einem Proxy](behind-a-proxy.md){.internal-link target=_blank} gesehen haben.

Dazu können Sie die `WSGIMiddleware` verwenden und damit Ihre WSGI-Anwendung wrappen, zum Beispiel Flask, Django usw.

## `WSGIMiddleware` verwenden

Sie müssen `WSGIMiddleware` importieren.
