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

檔案 `test_main.py` 會包含針對 `main.py` 的測試，現在可能像這樣：

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

## 執行 { #run-it }

如常執行測試：

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## 詳解 { #in-detail }

標記 `@pytest.mark.anyio` 告訴 pytest 這個測試函式應以非同步方式執行：

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

...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>

## Crear la App con un Solo Modelo { #create-the-app-with-a-single-model }

- Reduced server startup time. For IAM encryption with the root credentials, MinIO had
   to use a memory-hard function (Argon2) that (on purpose) consumes a lot of memory and CPU.
   The new KMS-based approach can use a key derivation function that is orders of magnitudes
   cheaper w.r.t. memory and CPU.

수동으로 설치하려면, [가상 환경](../../virtual-environments.md)을 만들고 활성화한 다음, 아래로 설치하세요:

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

이는 **OAuth2**가 `username`과 `password`를 보내기 위해 "form data"를 사용하기 때문입니다.

다음으로 예제를 실행하세요:
