Use base64 apenas se realmente precisar incluir dados binários em JSON e não puder usar arquivos para isso.

## Pydantic `bytes` { #pydantic-bytes }

Você pode declarar um modelo Pydantic com campos `bytes` e então usar `val_json_bytes` na configuração do modelo para indicar que deve usar base64 para *validar* os dados JSON de entrada; como parte dessa validação, ele decodificará a string base64 em bytes.

  });

  $("#confirmToDelete").on("show.bs.modal", function(event) {
    var button = $(event.relatedTarget);
    var docId = button.data("docid");
    var title = button.data("title");
    var url = button.data("url");

    $(this)
      .find(".modal-body #delete-doc-title")
      .text(title);
    $(this)
      .find(".modal-body #delete-doc-url")
      .text(url);
    $(this)

Dann verwenden wir den Request direkt und extrahieren den Body als `bytes`. Das bedeutet, dass FastAPI nicht einmal versucht, die Request-Payload als JSON zu parsen.

Und dann parsen wir in unserem Code diesen YAML-Inhalt direkt und verwenden dann wieder dasselbe Pydantic-Modell, um den YAML-Inhalt zu validieren:

efault.fn[z].Constructor=lt,o.default.fn[z].noConflict=function(){return o.default.fn[z]=X,lt._jQueryInterface};var rt="bs.modal",ut=o.default.fn.modal,ft="modal-open",dt="fade",ct="show",ht="modal-static",gt="hidden.bs.modal",mt="show.bs.modal",pt="focusin.bs.modal",_t="resize.bs.modal",vt="click.dismiss.bs.modal",yt="keydown.dismiss.bs.modal",bt="mousedown.dismiss.bs.modal",Et=".fixed-top, .fixed-bottom, .is-fixed, .sticky-top",Tt={backdrop:!0,keyboard:!0,focus:!0,show:!0},wt={backdrop:"(boole...

}))}_applyManipulationCallback(t,e){if(l(t))e(t);else for(const s of K.find(t,this._element))e(s)}}const Ut=".bs.modal",Gt="hidden.bs.modal",Jt="show.bs.modal",Zt="modal-open",te="show",ee="modal-static",se={backdrop:!0,focus:!0,keyboard:!0},ie={backdrop:"(boolean|string)",focus:"boolean",keyboard:"boolean"};class ne extends W{constructor(t,e){super(t,e),this._dialog=K.findOne(".modal-dialog",this._element),this._backdrop=this._initializeBackDrop(),this._focustrap=this._initializeFocusTrap(),thi...

Ensuite, dans notre code, nous analysons directement ce contenu YAML, puis nous utilisons à nouveau le même modèle Pydantic pour valider le contenu YAML :

{* ../../docs_src/path_operation_advanced_configuration/tutorial007_py310.py hl[24:31] *}

/// tip | Astuce

Ici, nous réutilisons le même modèle Pydantic.

Mais de la même manière, nous aurions pu le valider autrement.

Stellen wir uns vor, dass das Laden des Modells **eine ganze Weile dauern** kann, da viele **Daten von der Festplatte** gelesen werden müssen. Sie möchten das also nicht für jeden Request tun.
