[virtual environment](../virtual-environments.md){.internal-link target=_blank} 를 만들고, 활성화 시킨 뒤에 설치하세요. 예시:

```console
$ pip install httpx
```

///

`TestClient` 를 임포트하세요.

**FastAPI** 어플리케이션을 전달하여 `TestClient` 를 만드세요.

이름이 `test_` 로 시작하는 함수를 만드세요(`pytest` 의 표준적인 관례입니다).

`httpx` 를 사용하는 것과 같은 방식으로 `TestClient` 객체를 사용하세요.

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

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

## Importe `Form` { #import-form }

Importe `Form` de `fastapi`:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[3] *}

# 模板

**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

安装 `jinja2`：

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## 使用 `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

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

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

* Import `Jinja2Templates`.
* Create a `templates` object that you can reuse later.

Use `pylint` to check your Python changes. To install `pylint` and check a file
with `pylint` against TensorFlow's custom style definition:

```bash
pip install pylint
pylint --rcfile=tensorflow/tools/ci_build/pylintrc myfile.py
```

Note `pylint --rcfile=tensorflow/tools/ci_build/pylintrc` should run from the
top level tensorflow directory.

Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info

If you are planning to use digital signature algorithms like RSA or ECDSA, you should install the cryptography library dependency `pyjwt[crypto]`.
