Para receber arquivos enviados, primeiro instale [`python-multipart`](https://github.com/Kludex/python-multipart).

Garanta que você criou um [ambiente virtual](../virtual-environments.md), o ativou e então o instalou, por exemplo:

```console
$ pip install python-multipart
```

Isso é necessário, visto que os arquivos enviados são enviados como "dados de formulário".

Quando você instala o FastAPI (por exemplo, com `pip install "fastapi[standard]"`), ele vem com um programa de linha de comando que você pode executar no terminal.

Para executar sua aplicação FastAPI durante o desenvolvimento, você pode usar o comando `fastapi dev`:

如果你想玩玩看 JWT 權杖並了解其運作，請參考 [https://jwt.io](https://jwt.io/)。

## 安裝 `PyJWT` { #install-pyjwt }

我們需要安裝 `PyJWT` 才能在 Python 中產生與驗證 JWT 權杖。

請先建立並啟用一個[虛擬環境](../../virtual-environments.md)，然後安裝 `pyjwt`：

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | 說明

如果你打算使用像 RSA 或 ECDSA 這類的數位簽章演算法，應該安裝帶有加密函式庫相依的 `pyjwt[crypto]`。

如果你想动手体验 JWT 令牌并了解它的工作方式，请访问 [https://jwt.io](https://jwt.io/)。

## 安装 `PyJWT` { #install-pyjwt }

我们需要安装 `PyJWT`，以便在 Python 中生成和校验 JWT 令牌。

请确保创建并激活一个[虚拟环境](../../virtual-environments.md)，然后安装 `pyjwt`：

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | 信息

如果你计划使用类似 RSA 或 ECDSA 的数字签名算法，你应该安装加密库依赖项 `pyjwt[crypto]`。
