首先，你可能想了解 [帮助 FastAPI 及获取帮助](help-fastapi.md){.internal-link target=_blank}的基本方式。

## 开发

如果你已经克隆了源码仓库，并且需要深入研究代码，下面是设置开发环境的指南。

### 通过 `venv` 管理虚拟环境

你可以使用 Python 的 `venv` 模块在一个目录中创建虚拟环境：

<div class="termy">

```console
$ python -m venv env
```

</div>

这将使用 Python 程序创建一个 `./env/` 目录，然后你将能够为这个隔离的环境安装软件包。

### 激活虚拟环境

使用以下方法激活新环境：

//// tab | Linux, macOS

<div class="termy">

```console

```Python hl_lines="1  18"
{!../../docs_src/response_directly/tutorial002.py!}
```

### `HTMLResponse`

Takes some text or bytes and returns an HTML response, as you read above.

### `PlainTextResponse`

Takes some text or bytes and returns a plain text response.

```Python hl_lines="2  7  9"
{!../../docs_src/custom_response/tutorial005.py!}
```

It can be imported from `fastapi`:

```python
from fastapi.middleware.cors import CORSMiddleware
```

::: fastapi.middleware.gzip.GZipMiddleware

It can be imported from `fastapi`:

```python
from fastapi.middleware.gzip import GZipMiddleware
```

::: fastapi.middleware.httpsredirect.HTTPSRedirectMiddleware

It can be imported from `fastapi`:

```python

### Импортируйте `HTTPException`

```Python hl_lines="1"
{!../../docs_src/handling_errors/tutorial001.py!}
```

### Вызовите `HTTPException` в своем коде

`HTTPException` - это обычное исключение Python с дополнительными данными, актуальными для API.

Поскольку это исключение Python, то его не `возвращают`, а `вызывают`.

Para estes casos, você pode utilizar a técnica do Python de "desempacotamento" de um `dict` utilizando `**dict_to_unpack`:

```Python
old_dict = {
    "old key": "old value",
    "second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
```

Aqui, o `new_dict` terá todos os pares de chave-valor do `old_dict` mais o novo par de chave-valor:

```Python
{
    "old key": "old value",
