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

Isso ocorre porque o **OAuth2** usa "form data" para enviar o `username` e o `password`.

Execute o exemplo com:

<div class="termy">

```console
$ fastapi dev

### Vérifier la documentation API automatique { #check-the-automatic-api-docs }

Exécutez maintenant la commande `fastapi` :

<div class="termy">

```console
$ fastapi dev

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

</div>

## Get started

### 1. Prerequisites

- Docker 18.03 or above, refer here for [installation](https://docs.docker.com/install/).

### 2. Start etcd

etcd uses [gcr.io/etcd-development/etcd](https://console.cloud.google.com/gcr/images/etcd-development/GLOBAL/etcd) as a primary container registry.

```
rm -rf /tmp/etcd-data.tmp && mkdir -p /tmp/etcd-data.tmp && \
  podman rmi gcr.io/etcd-development/etcd:v3.3.9 || true && \

{* ../../docs_src/async_tests/app_a_py310/test_main.py *}

## Executá-lo { #run-it }

Você pode executar os seus testes normalmente via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Em Detalhes { #in-detail }

O marcador `@pytest.mark.anyio` informa ao pytest que esta função de teste deve ser invocada de maneira assíncrona:

설정을 쉽게 할 수 있는 유틸리티가 있으며, 이를 **FastAPI** 애플리케이션에서 직접 사용할 수 있습니다(Starlette 제공).

## 의존성 설치 { #install-dependencies }

[가상 환경](../virtual-environments.md)을 생성하고, 활성화한 후 `jinja2`를 설치해야 합니다:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

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

* `Jinja2Templates`를 가져옵니다.
* 나중에 재사용할 수 있는 `templates` 객체를 생성합니다.

```bash
# 向宇宙打印问候
echo "Hello universe"
```

...以及一个控制台代码示例...

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>
<span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting server
        Searching for package file structure
```

...以及另一个控制台代码示例...

```console
// 创建目录 "code"
$ mkdir code
// 切换到该目录
$ cd code
```

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
* 在返回模板的*路径操作*中声明 `Request` 参数

        }
      } else {
        tag jobName
        value 'Job Name', jobName
      }

      tag 'CI'
      link 'CI Build', buildUrl
      link 'GCP Upload', "https://console.cloud.google.com/storage/browser/_details/elasticsearch-ci-artifacts/jobs/${URLEncoder.encode(jobName, "UTF-8")}/build/${buildNumber}.tar.bz2"
      value 'Job Number', buildNumber
      if (jobBranch) {
        tag jobBranch

```

...y un ejemplo de código de consola...

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>
<span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting server
        Searching for package file structure
```

...y otro ejemplo de código de consola...

```console
// Crea un directorio "Code"
$ mkdir code

## Instalar `SQLModel` { #install-sqlmodel }

Primero, asegúrate de crear tu [entorno virtual](../virtual-environments.md), actívalo, y luego instala `sqlmodel`:

<div class="termy">

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

</div>
