Você também pode especificar se o seu backend permite:

* Credenciais (Cabeçalhos de autorização, Cookies, etc).
* Métodos HTTP específicos (`POST`, `PUT`) ou todos eles com o curinga `"*"`.

# Testing Dependencies with Overrides

## Overriding dependencies during testing

There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).

}

// LogAlwaysIf prints a detailed error message during
// the execution of the server.
func LogAlwaysIf(ctx context.Context, subsystem string, err error, errKind ...interface{}) {
	if err == nil {
		return
	}
	logIf(ctx, subsystem, err, errKind...)
}

// LogIf prints a detailed error message during
// the execution of the server, if it is not an
// ignored error.

You can probably skip this part.

///

There's an alternative way to define this logic to be executed during *startup* and during *shutdown*.

You can define event handlers (functions) that need to be executed before the application starts up, or when the application is shutting down.

	DeleteMarker            bool // Is only set in DELETE operations for delete marker replication
	CheckDMReplicationReady bool // Is delete marker ready to be replicated - set only during HEAD
	Tagging                 bool // Is only in GET/HEAD operations to return tagging metadata along with regular metadata and body.

	UserDefined         map[string]string   // only set in case of POST/PUT operations

	rv=$?
	if [ $rv -eq 0 ]; then
		echo "Failed to receive an error"
		exit 1
	fi
	echo "Received an error during complete-multipart as expected: $err"
}

function main() {
	start_port=$(shuf -i 10000-65000 -n 1)
	start_minio_10drive ${start_port}
}

## Settings in a dependency

In some occasions it might be useful to provide the settings from a dependency, instead of having a global object with `settings` that is used everywhere.

This could be especially useful during testing, as it's very easy to override a dependency with your own custom settings.

### The config file

Coming from the previous example, your `config.py` file could look like:

```Python hl_lines="10"

### FastAPI Experts - Last Month

These are the users that have been [helping others the most with questions in GitHub](help-fastapi.md#help-others-with-questions-in-github){.internal-link target=_blank} during the last month. 🤓

{% if people %}
<div class="user-list user-list-center">
{% for user in people.last_month_experts[:10] %}

Therefore, if you run a `tf.train.Server` in your network, anybody with access
to the network can execute arbitrary code with the privileges of the user
running the `tf.train.Server`.

## Untrusted inputs during training and prediction

TensorFlow supports a wide range of input data formats. For example it can
process images, audio, videos, and text. There are several modules specialized
