### Internal metadata for replication

But because of our changes in `GzipRequest.body`, the request body will be automatically decompressed when it is loaded by **FastAPI** when needed.

## Accessing the request body in an exception handler { #accessing-the-request-body-in-an-exception-handler }

/// tip

This style of using `async` and `await` is relatively new in the language.

But it makes working with asynchronous code a lot easier.

This same syntax (or almost identical) was also included recently in modern versions of JavaScript (in Browser and NodeJS).

But before that, handling asynchronous code was quite more complex and difficult.

        if security_name not in operation_security_dict:
            operation_security_dict[security_name] = []
        for scope in security_dependency.oauth_scopes or []:
            if scope not in operation_security_dict[security_name]:
                operation_security_dict[security_name].append(scope)
    operation_security = [
        {name: scopes} for name, scopes in operation_security_dict.items()
    ]

Now, when the clients **create a new hero**, they will send the `secret_name`, it will be stored in the database, but those secret names won't be returned in the API to the clients.

/// tip

This is how you would handle **passwords**. Receive them, but don't return them in the API.

You would also **hash** the values of the passwords before storing them, **never store them in plain text**.

///

The fields of `HeroCreate` are:

* `name`

## `Query` zu `Annotated` im `q`-Parameter hinzufügen { #add-query-to-annotated-in-the-q-parameter }

Da wir nun `Annotated` haben, in das wir mehr Informationen (in diesem Fall einige zusätzliche Validierungen) einfügen können, fügen Sie `Query` innerhalb von `Annotated` hinzu und setzen Sie den Parameter `max_length` auf `50`:

/// tip

If you want to call `async` functions in your tests apart from sending requests to your FastAPI application (e.g. asynchronous database functions), have a look at the [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} in the advanced tutorial.

## Separating tests { #separating-tests }

In a real application, you probably would have your tests in a different file.

 * When an instance is created with a File object, the content is cached in the specified file.
 *
 * <p>The {@code close()} method deletes the file if the content is cached in a file.
 *
 * <p>The {@code getInputStream()} method provides an InputStream to read the cached content.
 * If the content is cached in a file, it returns a FileInputStream. If the content is cached in memory,
