Есть утилиты для простой настройки, которые вы можете использовать прямо в своем приложении **FastAPI** (предоставляются Starlette).

## Установка зависимостей { #install-dependencies }

Убедитесь, что вы создали [виртуальное окружение](../virtual-environments.md), активировали его и установили `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

Bunu kolayca yapılandırmak için, doğrudan **FastAPI** uygulamanızda kullanabileceğiniz yardımcı araçlar vardır (Starlette tarafından sağlanır).

## Bağımlılıkları Yükleme { #install-dependencies }

Bir [sanal ortam](../virtual-environments.md) oluşturduğunuzdan, etkinleştirdiğinizden ve `jinja2`'yi yüklediğinizden emin olun:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

import warnings

import pytest
from fastapi import FastAPI, File, Form, UploadFile
from fastapi.dependencies.utils import (
    multipart_incorrect_install_error,
    multipart_not_installed_error,
)


def test_incorrect_multipart_installed_form(monkeypatch):
    monkeypatch.setattr("python_multipart.__version__", "0.0.12")
    with warnings.catch_warnings(record=True):
        warnings.simplefilter("always")

### Dépendances { #dependencies }

La même chose s'applique aux [dépendances](tutorial/dependencies/index.md). Si une dépendance est définie avec `def` plutôt que `async def`, elle est exécutée dans la threadpool externe.

### Sous-dépendances { #sub-dependencies }

Existem utilitários para configurá-lo facilmente que você pode usar diretamente em sua aplicação **FastAPI** (fornecidos pelo Starlette).

## Instalar dependências { #install-dependencies }

Certifique-se de criar um [ambiente virtual](../virtual-environments.md), ativá-lo e instalar `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

Você pode usar um código de fechamento dos [códigos válidos definidos na especificação](https://tools.ietf.org/html/rfc6455#section-7.4.1).

### Tente os WebSockets com dependências { #try-the-websockets-with-dependencies }

Execute sua aplicação:

<div class="termy">

```console
$ fastapi dev

Il existe des utilitaires pour le configurer facilement que vous pouvez utiliser directement dans votre application **FastAPI** (fournis par Starlette).

## Installer les dépendances { #install-dependencies }

Vous devez créer un [environnement virtuel](../virtual-environments.md), l'activer, puis installer `jinja2` :

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

            Charsets.ISO_8859_1, "\n"
        )
    }

    private
    fun findLatest(name: String, notation: String, dest: Properties) {
        val libDependencies = arrayOf(project.dependencies.create(notation))
        @Suppress("SpreadOperator")
        val templateVersionConfiguration = project.configurations.detachedConfiguration(*libDependencies)

Puedes usar un código de cierre de los [códigos válidos definidos en la especificación](https://tools.ietf.org/html/rfc6455#section-7.4.1).

### Prueba los WebSockets con dependencias { #try-the-websockets-with-dependencies }

Ejecuta tu aplicación:

<div class="termy">

```console
$ fastapi dev

# 模板 { #templates }

**FastAPI** 支持多种模板引擎。

Flask 等工具使用的 Jinja2 是最用的模板引擎。

在 Starlette 的支持下，**FastAPI** 应用可以直接使用工具轻易地配置 Jinja2。

## 安装依赖项 { #install-dependencies }

确保你创建一个[虚拟环境](../virtual-environments.md)，激活它，并安装 `jinja2`：

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## 使用 `Jinja2Templates` { #using-jinja2templates }

* 导入 `Jinja2Templates`
* 创建可复用的 `templates` 对象
