## Les modèles Pydantic

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> est une bibliothèque Python pour effectuer de la validation de données.

Vous déclarez la forme de la donnée avec des classes et des attributs.

Chaque attribut possède un type.

Если вы хотите поиграть с JWT-токенами и посмотреть, как они работают, посмотрите <a href="https://jwt.io/" class="external-link" target="_blank">https://jwt.io</a>.

## Установка `PyJWT` { #install-pyjwt }

Нам необходимо установить `pyjwt` для генерации и проверки JWT-токенов на языке Python.

## Proibindo Cabeçalhos adicionais { #forbid-extra-headers }

Em alguns casos de uso especiais (provavelmente não muito comuns), você pode querer **restringir** os cabeçalhos que você quer receber.

Você pode usar a configuração dos modelos do Pydantic para proibir (`forbid`) quaisquer campos `extra`:

{* ../../docs_src/header_param_models/tutorial002_an_py310.py hl[10] *}

## Guia oficial { #official-guide }

O Pydantic tem um <a href="https://docs.pydantic.dev/latest/migration/" class="external-link" target="_blank">Guia de Migração</a> oficial do v1 para o v2.

Ele também inclui o que mudou, como as validações agora são mais corretas e rigorosas, possíveis ressalvas, etc.

# CORS（跨域资源共享）

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS 或者「跨域资源共享」</a> 指浏览器中运行的前端拥有与后端通信的 JavaScript 代码，而后端处于与前端不同的「源」的情况。

## 源

源是协议（`http`，`https`）、域（`myapp.com`，`localhost`，`localhost.tiangolo.com`）以及端口（`80`、`443`、`8080`）的组合。

因此，这些都是不同的源：

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

即使它们都在 `localhost` 中，但是它们使用不同的协议或者端口，所以它们都是不同的「源」。

## 步骤

rTemplate:'<span class="text-danger"></span>',onLoadStart:function(){},onLoadDone:function(e){return e},onLoadFail:function(e,t,a){}},f=function(){function e(e,t){if(this._element=e,this._parent=e.parents(".card").first(),this._settings=n.default.extend({},d,t),this._overlay=n.default(this._settings.overlayTemplate),e.hasClass(s)&&(this._parent=e),""===this._settings.source)throw new Error("Source url was not defined. Please specify a url in your CardRefresh source option.")}var t=e.prototype;return...

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

erhält er eine Error-Response, die ihm mitteilt, dass das Feld `extra` nicht erlaubt ist:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }
    ]
