By declaring types for your variables, editors and tools can give you better support.

This is just a **quick tutorial / refresher** about Python type hints. It covers only the minimum necessary to use them with **FastAPI**... which is actually very little.

**FastAPI** is all based on these type hints, they give it many advantages and benefits.

                            "required": True,
                            "schema": {
                                "title": "The ID of the item to get",
                                "maximum": 1000.0,
                                "minimum": 0.0,
                                "type": "integer",
                            },
                            "name": "item_id",
                            "in": "path",

Diese Middleware verarbeitet sowohl Standard- als auch Streaming-Responses.

```Python hl_lines="2  6"
{!../../../docs_src/advanced_middleware/tutorial003.py!}
```

Die folgenden Argumente werden unterstützt:

* `minimum_size` – Antworten, die kleiner als diese Mindestgröße in Bytes sind, nicht per GZip komprimieren. Der Defaultwert ist `500`.

## Andere Middlewares

Es gibt viele andere ASGI-Middlewares.

Zum Beispiel:

    * **Kolay**: Kolay öğrenip kolay kullanmak için tasarlandı. Daha az döküman okuma daha çok iş.
    * **Kısa**: Minimum kod tekrarı. Her parametre bildiriminde birden çok özellik.
    * **Güçlü**: Production-ready. Otomatik interaktif dökümantasyon.

🍵 🗜 📨 🙆 📨 👈 🔌 `"gzip"` `Accept-Encoding` 🎚.

🛠️ 🔜 🍵 👯‍♂️ 🐩 & 🎥 📨.

```Python hl_lines="2  6"
{!../../../docs_src/advanced_middleware/tutorial003.py!}
```

📄 ❌ 🐕‍🦺:

* `minimum_size` - 🚫 🗜 📨 👈 🤪 🌘 👉 💯 📐 🔢. 🔢 `500`.

## 🎏 🛠️

📤 📚 🎏 🔫 🛠️.

🖼:

* <a href="https://docs.sentry.io/platforms/python/asgi/" class="external-link" target="_blank">🔫</a>

## `GZipMiddleware`

处理 `Accept-Encoding` 请求头中包含 `gzip` 请求的 GZip 响应。

中间件会处理标准响应与流响应。

```Python hl_lines="2  6"
{!../../../docs_src/advanced_middleware/tutorial003.py!}
```

支持以下参数：

* `minimum_size` - 小于最小字节的响应不使用 GZip。 默认值是 `500`。

## 其它中间件

除了上述中间件外，FastAPI 还支持其它ASGI 中间件。

例如：

* <a href="https://docs.sentry.io/platforms/python/asgi/" class="external-link" target="_blank">Sentry</a>

* Validation pour la plupart (ou tous?) les **types de données** Python incluant:
    * objets JSON (`dict`).
    * listes JSON (`list`) définissant des types d'éléments.
    * Champs String (`str`), définition de longueur minimum ou maximale.
    * Nombres (`int`, `float`) avec valeur minimale and maximale, etc.

* Validation pour des types plus exotiques, tel que:
    * URL.
    * Email.
    * UUID.
    * ...et autres.

**Осторожно, спойлер**: руководство пользователя включает в себя:

* Объявление **параметров** из других мест, таких как: **заголовки**, **cookies**, **поля формы** и **файлы**.
* Как установить **ограничительные проверки** такие как `maximum_length` или `regex`.
* Очень мощная и простая в использовании система **<abbr title="также известная как компоненты, ресурсы, провайдеры, сервисы, инъекции">внедрения зависимостей</abbr>**.

Falcon is another high performance Python framework, it is designed to be minimal, and work as the foundation of other frameworks like Hug.

**Spoiler alert**: il tutorial - Guida Utente include:

* Dichiarazione di **parameters** da altri posti diversi come: **headers**, **cookies**, **form fields** e **files**.
* Come stabilire **vincoli di validazione** come `maximum_length` o `regex`.
* Un sistema di **<abbr title="detto anche components, resources, providers, services, injectables">Dependency Injection</abbr>** facile da usare e molto potente.
e potente.
