FastAPI is built on top of **Pydantic**, and I have been showing you how to use Pydantic models to declare requests and responses.

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

{* ../../docs_src/dataclasses/tutorial001.py hl[1,7:12,19:20] *}

   * of {@code map}.
   *
   * @throws IllegalArgumentException if an attempt to {@code put} any entry fails. Note that some
   *     map entries may have been added to the bimap before the exception was thrown.
   */
  @Override
  void putAll(Map<? extends K, ? extends V> map);

  /**
   * {@inheritDoc}

import jcifs.internal.smb1.ServerMessageBlock;
import jcifs.internal.util.SMBUtil;

/**
 * SMB1 Read AndX request message.
 *
 * This command is used to read data from a file that has been
 * previously opened with an Open command.
 */
public class SmbComReadAndX extends AndXServerMessageBlock {

    private long offset;
    private int fid;
    int openTimeout;
    int maxCount, minCount, remaining;

5. Sie können andere Standard-Typannotationen mit Datenklassen als Requestbody verwenden.

    In diesem Fall handelt es sich um eine Liste von `Item`-Datenklassen.

6. Hier geben wir ein Dictionary zurück, das `items` enthält, welches eine Liste von Datenklassen ist.

    FastAPI ist weiterhin in der Lage, die Daten nach JSON zu <abbr title="Konvertieren der Daten in ein übertragbares Format">serialisieren</abbr>.

Sie können tatsächlich die gleiche Technik mit einer HTTP `PUT` Operation verwenden.
