If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

They will receive an error response telling them that the field `extra` is not allowed:

```json
{
    "detail": [
        {

func (args *ReaderArgs) IsEmpty() bool {
	return !args.unmarshaled
}

// UnmarshalXML - decodes XML data.
func (args *ReaderArgs) UnmarshalXML(d *xml.Decoder, start xml.StartElement) error {
	// Make subtype to avoid recursive UnmarshalXML().
	type subReaderArgs ReaderArgs
	parsedArgs := subReaderArgs{}
	if err := d.DecodeElement(&parsedArgs, &start); err != nil {
		return err
	}

Bir `Request` ayrıca `request.receive` içerir; bu, request'in body'sini "almak" (receive etmek) için kullanılan bir fonksiyondur.

`scope` `dict`'i ve `receive` fonksiyonu, ASGI spesifikasyonunun parçalarıdır.

Ve bu iki şey, `scope` ve `receive`, yeni bir `Request` instance'ı oluşturmak için gerekenlerdir.

                .session(session)
                .source(Sources.buildSource(tempPomPath))
                .requestType(ModelBuilderRequest.RequestType.BUILD_EFFECTIVE)
                .recursive(false) // We only want this POM, not its modules
                .build();

        ModelBuilderResult result = modelBuilder.newSession().build(request);
        Model effectiveModel = result.getEffectiveModel();

/**
 * Filter for rate limiting to protect against bot attacks and excessive requests.
 * Tracks request counts per IP address and blocks excessive requests based on configurable thresholds.

public class RateLimitFilter implements Filter {

    private static final Logger logger = LogManager.getLogger(RateLimitFilter.class);

    }

    /**
     * Get the maximum size for receive operations

    public int getMaxReceiveSize() {
        return maxReceiveSize;
    }

    /**

Ein `Request` hat auch ein `request.receive`, welches eine Funktion ist, die den Body des Requests <abbr title="Englisch „receive“">empfängt</abbr>.

Das `scope`-`dict` und die `receive`-Funktion sind beide Teil der ASGI-Spezifikation.

Und diese beiden Dinge, `scope` und `receive`, werden benötigt, um eine neue `Request`-Instanz zu erstellen.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

If a client tries to send some **extra headers**, they will receive an **error** response.
