# WebSockets { #websockets }

Vous pouvez utiliser [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) avec **FastAPI**.

## Installer `websockets` { #install-websockets }

Vous devez créer un [environnement virtuel](../virtual-environments.md), l'activer, et installer `websockets` (une bibliothèque Python qui facilite l'utilisation du protocole « WebSocket ») :

<div class="termy">

```console
$ pip install websockets

# 更大型的應用程式 - 多個檔案 { #bigger-applications-multiple-files }

如果你正在建置一個應用程式或 Web API，很少會把所有東西都放在單一檔案裡。

FastAPI 提供了一個方便的工具，讓你在維持彈性的同時，幫你組織應用程式的結構。

/// info | 資訊

如果你來自 Flask，這相當於 Flask 的 Blueprints。

## 範例檔案結構 { #an-example-file-structure }

假設你有如下的檔案結構：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   ├── dependencies.py
│   └── routers
│   │   ├── __init__.py
│   │   ├── items.py

        * Ayrıca token çalınırsa risk daha düşük olur. Çoğu durumda, sonsuza kadar çalışacak kalıcı bir anahtar gibi değildir.
* Frontend bu token’ı geçici olarak bir yerde saklar.
* Kullanıcı frontend’de tıklayarak web uygulamasının başka bir bölümüne gider.
* Frontend’in API’den daha fazla veri alması gerekir.
    * Ancak o endpoint için authentication gereklidir.

* Cela permet également d'utiliser la **génération automatique de code client** dans de nombreux langages.

### Documentation automatique { #automatic-docs }

Documentation d'API interactive et interfaces web d'exploration. Comme le framework est basé sur OpenAPI, plusieurs options existent, 2 incluses par défaut.

```sh
npx @hey-api/openapi-ts -i http://localhost:8000/openapi.json -o src/client
```

Bu komut `./src/client` içine bir TypeScript SDK üretecektir.

Web sitelerinde [`@hey-api/openapi-ts` kurulumunu](https://heyapi.dev/openapi-ts/get-started) öğrenebilir ve [üretilen çıktıyı](https://heyapi.dev/openapi-ts/output) inceleyebilirsiniz.

### SDK'yı Kullanma { #using-the-sdk }

# Größere Anwendungen – mehrere Dateien { #bigger-applications-multiple-files }

Wenn Sie eine Anwendung oder eine Web-API erstellen, ist es selten der Fall, dass Sie alles in einer einzigen Datei unterbringen können.

**FastAPI** bietet ein praktisches Werkzeug zur Strukturierung Ihrer Anwendung bei gleichzeitiger Wahrung der Flexibilität.

Wenn Sie von Flask kommen, wäre dies das Äquivalent zu Flasks Blueprints.

* The formerly publicly-available cAdvisor web UI that the kubelet ran on port 4194 by default is now turned off by default. The flag configuring what port to run this UI on `--cadvisor-port` was deprecated in v1.10. Now the default is `--cadvisor-port=0`, in other words, to not run the web server. If you still need to run cAdvisor, the recommended way to run it is via a DaemonSet. Note that the `--cadvisor-port` will...
