*   Include unit tests when you contribute new features, as they help to a)
    prove that your code works correctly, and b) guard against future breaking
    changes to lower the maintenance cost.
*   Bug fixes also generally require unit tests, because the presence of bugs
    usually indicates insufficient test coverage.
*   Keep API compatibility in mind when you change code in core TensorFlow,
    e.g., code in

      .url(url)
      .build();

Post to a Server
----------------

This program posts data to a service. [Full source][post_example].

```java
public static final MediaType JSON = MediaType.get("application/json");

OkHttpClient client = new OkHttpClient();

/// tip | Consejo

Nota que en este caso estamos usando una función estándar de Python `open()` que interactúa con un archivo.

Entonces, involucra I/O (entrada/salida), que requiere "esperar" para que las cosas se escriban en el disco.

Pero `open()` no usa `async` y `await`.

Por eso, declaramos la función manejadora del evento con `def` estándar en vez de `async def`.

///

### `startup` y `shutdown` juntos
