If you do this, you have to make sure each one of your *path operation functions* has a unique name.

Even if they are in different modules (Python files).

## Exclude from OpenAPI { #exclude-from-openapi }

```python
from main import app
```

Kodunuz şöyle yapılandırılmışsa:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

O zaman `entrypoint`'i şöyle ayarlardınız:

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

Bu da şuna eşdeğer olur:

```python
from backend.main import app
```

Before, this page used to list links to external articles.

But now that FastAPI is the backend framework with the most GitHub stars across languages, and the most starred and used framework in Python, it no longer makes sense to attempt to list all articles written about it.

## GitHub Repositories

Most starred [GitHub repositories with the topic `fastapi`](https://github.com/topics/fastapi):

总之，ASGI 中间件是类，并把 ASGI 应用作为第一个参数。

因此，有些第三方 ASGI 中间件的文档推荐以如下方式使用中间件：

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

但 FastAPI（实际上是 Starlette）提供了一种更简单的方式，能让内部中间件在处理服务器错误的同时，还能让自定义异常处理器正常运作。

为此，要使用 `app.add_middleware()` （与 CORS 中的示例一样）。

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

これは**小さなトリック**で、便利な場合がありますが、頻繁に必要になることはありません。

次のことをしたい場合:

* `q`クエリパラメータを`Query`もデフォルト値もなしで宣言する
* パスパラメータ`item_id`を`Path`を使って宣言する
* それらを別の順番にする
* `Annotated`を使わない

...Pythonにはそのための少し特殊な構文があります。

関数の最初のパラメータとして`*`を渡します。

Pythonはその`*`で何かをすることはありませんが、それ以降のすべてのパラメータがキーワード引数（キーと値のペア）として呼ばれるべきものであると知っているでしょう。それは<abbr title="From: K-ey W-ord Arg-uments - キーワード引数"><code>kwargs</code></abbr>としても知られています。たとえデフォルト値がなくても。

# easier to find and read.

To use `EmailStr`, first install [`email-validator`](https://github.com/JoshData/python-email-validator).

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and then install it, for example:

```console
$ pip install email-validator
```
