```
--ftp="address=:3021"
```

### Change FTP passive port range

By default FTP requests OS to give a free port automatically, however you may want to restrict
this to specific ports in certain restricted environments via

```
--ftp="passive-port-range=30000-40000"
```

### Change default SFTP port

Default port '8022' can be changed via

```
--sftp="address=:3022"
```

### TLS (FTP)

**強烈建議**你編寫或複製程式碼、進行修改並在本地端運行。

在編輯器中使用它，才能真正體會到 FastAPI 的好處，可以看到你只需編寫少量程式碼，以及所有的型別檢查、自動補齊等功能。

## 安裝 FastAPI

第一步是安裝 FastAPI。

確保你建立一個[虛擬環境](../virtual-environments.md){.internal-link target=_blank}，啟用它，然後**安裝 FastAPI**：

<div class="termy">

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

---> 100%
```

</div>

/// note

Para recibir archivos subidos, primero instala <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo y luego instalarlo, por ejemplo:

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

Esto es porque los archivos subidos se envían como "form data".

# WebSockets

여러분은 **FastAPI**에서 <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">WebSockets</a>를 사용할 수 있습니다.

## `WebSockets` 설치

[가상 환경](../virtual-environments.md){.internal-link target=_blank)를 생성하고 활성화한 다음, `websockets`를 설치하세요:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets 클라이언트

### 프로덕션 환경에서

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
```

Esto se debe a que **OAuth2** utiliza "form data" para enviar el `username` y `password`.

## Установка `PyJWT`

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

Убедитесь, что вы создали [виртуальное окружение](../../virtual-environments.md){.internal-link target=_blank}, активируйте его, а затем установите `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

            method.setAccessible(true);
          } catch (AccessControlException e) {
            // OK: the method is accessible to us anyway. The setAccessible call is only for
            // unusual execution environments where that might not be true.
          }
          builder.put(method.getName(), method);
        }
      }
      typeVariableMethods = builder.buildKeepingLast();
    }

Para usar `EmailStr`, primeiro instale <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ative-o e instale-o, por exemplo:

```console
$ pip install email-validator
```

ou com:

```console
$ pip install "pydantic[email]"
```

## Instalar o `SQLModel`

Primeiro, certifique-se de criar seu [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e, em seguida, instalar o `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>
