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

Nós precisamos instalar o `PyJWT` para criar e verificar os tokens JWT em Python.

Certifique-se de criar um [ambiente virtual](../../virtual-environments.md){.internal-link target=_blank}, ativá-lo e então instalar o `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | Informação

///

//// tab | `pip`

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

////

//// tab | `uv`

<a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">`uv`</a>를 사용하는 경우:

<div class="termy">

```console
$ uv pip install "fastapi[standard]"
---> 100%
```

</div>

# 请求表单与文件

FastAPI 支持同时使用 `File` 和 `Form` 定义文件和表单字段。

/// info | 说明

接收上传文件或表单数据，要预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如，`pip install python-multipart`。

///

## 导入 `File` 与 `Form`

{* ../../docs_src/request_forms_and_files/tutorial001.py hl[1] *}

## 定义 `File` 与 `Form` 参数

创建文件和表单参数的方式与 `Body` 和 `Query` 一样：

fi

# SqlServer for Mac M1
if [[ -z $GITHUB_ACTION && -d tests ]]; then
  cd tests
  if [[ $(uname -a) == *" arm64" ]]; then
    MSSQL_IMAGE=mcr.microsoft.com/azure-sql-edge docker compose up -d --wait
    go install github.com/microsoft/go-sqlcmd/cmd/sqlcmd@latest || true
    for query in \
      "IF DB_ID('gorm') IS NULL CREATE DATABASE gorm" \
      "IF SUSER_ID (N'gorm') IS NULL CREATE LOGIN gorm WITH PASSWORD = 'LoremIpsum86';" \

Entretanto, se você usar o comando `pip install fastapi`, o pacote `python-multipart` não é incluído por padrão.

Para instalá-lo manualmente, certifique-se de criar um [ambiente virtual](../../virtual-environments.md){.internal-link target=_blank}, ativá-lo e então instalá-lo com:

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

Sin embargo, si usas el comando `pip install fastapi`, el paquete `python-multipart` no se incluye por defecto.

Para instalarlo manualmente, asegúrate de crear un [entorno virtual](../../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo con:

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

body:
  - type: dropdown
    id: issue-type
    attributes:
      label: Issue type
      description: What type of issue would you like to report?
      multiple: false
      options:
        - Bug
        - Build/Install
        - Performance
        - Support
        - Feature Request
        - Documentation Feature Request
        - Documentation Bug
        - Others
    validations:
      required: true
  - type: markdown

## 使用 `TestClient`

/// info | 信息

要使用 `TestClient`，先要安装 <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

例：`pip install httpx`.

///

导入 `TestClient`.

通过传入你的**FastAPI**应用创建一个 `TestClient` 。

创建名字以 `test_` 开头的函数（这是标准的 `pytest` 约定）。

像使用 `httpx` 那样使用 `TestClient` 对象。

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, diese aktivieren und es dann installieren, z. B.:

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

                    .hasArg()
                    .get());
            options.addOption(Option.builder(ALTERNATE_INSTALLATION_SETTINGS)
                    .longOpt("install-settings")
                    .desc("Alternate path for the installation settings file")
                    .hasArg()
                    .get());
            options.addOption(Option.builder(ALTERNATE_USER_TOOLCHAINS)
