如需深入了解 JWT 令牌，了解它的工作方式，请参阅 <a href="https://jwt.io/" class="external-link" target="_blank">https://jwt.io</a>。

## 安装 `PyJWT`

安装 `PyJWT`，在 Python 中生成和校验 JWT 令牌：

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | "说明"

如果您打算使用类似 RSA 或 ECDSA 的数字签名算法，您应该安装加密库依赖项 `pyjwt[crypto]`。

Führen Sie nun `uvicorn` mit der Hauptanwendung aus. Wenn Ihre Datei `main.py` lautet, wäre das:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Die Variable `app` ist dieselbe, auf die sich der Befehl `uvicorn` bezieht:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Wenn Sie Ihre Anwendung wie folgt erstellen:

```Python hl_lines="3"

## GunicornとUvicornをインストールする

<div class="termy">

```console
$ pip install "uvicorn[standard]" gunicorn

---> 100%
```

</div>

これによりUvicornと（高性能を得るための）標準（`standard`）の追加パッケージとGunicornの両方がインストールされます。

## UvicornのワーカーとともにGunicornを実行する

Gunicornを以下のように起動させることができます:

<div class="termy">

```console

    padding:0;
}
.footer ul {
    margin:20px 0 5px 0;
}
.header ul li, .footer ul li {
    list-style:none;
    font-size:1.2em;
}
/*
Heading styles
*/
div.details ul.blockList ul.blockList ul.blockList li.blockList h4, div.details ul.blockList ul.blockList ul.blockListLast li.blockList h4 {
    background-color:#dee3e9;
    border-top:1px solid #9eadc0;
    border-bottom:1px solid #9eadc0;

### Checando a documentação

Você pode ver os headers necessários na interface gráfica da documentação em `/docs`:

<div class="screenshot">

</div>

### Proibindo Cabeçalhos adicionais

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

## Check the Docs

You can see the defined cookies in the docs UI at `/docs`:

Have in mind that, as **browsers handle cookies** in special ways and behind the scenes, they **don't** easily allow **JavaScript** to touch them.
