You can optionally deploy your FastAPI app to <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>, go and join the waiting list if you haven't. 🚀

If you already have a **FastAPI Cloud** account (we invited you from the waiting list 😉), you can deploy your application with one command.

Before deploying, make sure you are logged in:

<div class="termy">

```console
$ fastapi login

      // the exception immediately

      // Register a listener on each Future in the list to update the state of this future.
      // Note that if all the futures on the list are done prior to completing this loop, the last
      // call to addListener() will callback to setOneValue(), transitively call our cleanup
      // listener, and set this.futures to null.

    )
    val interceptor =
      Interceptor { chain: Interceptor.Chain ->
        // The network request has everything: User-Agent, Host, Accept-Encoding.
        val networkRequest = chain.request()
        assertThat(networkRequest.header("User-Agent")).isNotNull()
        assertThat(networkRequest.header("Host")).isEqualTo(
          server.hostName + ":" + server.port,
        )

Pero por defecto, todo **"simplemente funciona"**.

### Validación { #validation }

* Validación para la mayoría (¿o todas?) de los **tipos de datos** de Python, incluyendo:
    * Objetos JSON (`dict`).
    * Array JSON (`list`) definiendo tipos de elementos.

ahead of the loop in this program:
</p>

<pre>
n := 0
for e := list; e != nil; e = e.next {
	n++
}
i := *p
*q = 1
</pre>

<p>
If <code>list</code> pointed to a cyclic list,
then the original program would never access <code>*p</code> or <code>*q</code>,
but the rewritten program would.

    .sslSocketFactory(clientCertificates.sslSocketFactory(), clientCertificates.trustManager())
    .build();
```

Client Authentication
---------------------

The above scenario is representative of most TLS set ups: the client uses certificates to validate
the identity of a server. The converse is also possible. Here we create a server that authenticates
a client and a client that authenticates a server.

```java

    TF_DeprecatedSession* session, TF_Status* status);

// Deallocates the device list.
TF_CAPI_EXPORT extern void TF_DeleteDeviceList(TF_DeviceList* list);

// Counts the number of elements in the device list.
TF_CAPI_EXPORT extern int TF_DeviceListCount(const TF_DeviceList* list);

// Retrieves the full name of the device (e.g. /job:worker/replica:0/...)

            } else {

                /* On NT without Unicode the fileNameLength
                 * includes the '\0' whereas on win98 it doesn't. I
                 * guess most clients only support non-unicode so
                 * they don't run into this.
                 */

                /* UPDATE: Maybe not! Could this be a Unicode alignment issue. I hope

        list.addLast(null);
        list.addLast("1");
        list.addLast("2");
        assertThat(list.remove("3"), is(not(true)));
        assertThat(list.remove("1"), is(true));
        assertThat(list.remove(null), is(true));
        list.clear();
        list.addLast("1");
        list.addLast("2");
        list.addLast("3");
        list.remove(1);
