Aber schauen wir uns zunächst einmal diese grundlegenden **konzeptionellen Ideen** an. Diese Konzepte gelten auch für jede andere Art von Web-API. 💡

## Sicherheit – HTTPS { #security-https }

Im [vorherigen Kapitel über HTTPS](https.md){.internal-link target=_blank} haben wir erfahren, wie HTTPS Verschlüsselung für Ihre API bereitstellt.

But for now, let's check these important **conceptual ideas**. These concepts also apply to any other type of web API. 💡

## Security - HTTPS { #security-https }

In the [previous chapter about HTTPS](https.md){.internal-link target=_blank} we learned about how HTTPS provides encryption for your API.

We also saw that HTTPS is normally provided by a component **external** to your application server, a **TLS Termination Proxy**.

## Install `websockets` { #install-websockets }

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `websockets` (a Python library that makes it easy to use the "WebSocket" protocol):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

///

## Без Pydantic

</pre>
```

</div>

**強烈建議**你編寫或複製程式碼、進行修改並在本地端運行。

在編輯器中使用它，才能真正體會到 FastAPI 的好處，可以看到你只需編寫少量程式碼，以及所有的型別檢查、自動補齊等功能。

## 安裝 FastAPI

第一步是安裝 FastAPI。

確保你建立一個[虛擬環境](../virtual-environments.md){.internal-link target=_blank}，啟用它，然後**安裝 FastAPI**：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note

set the env. variable `MINIO_KMS_SECRET_KEY` and start/restart the MinIO server. For more details about KES and how
to set it up refer to our [KMS Guide](https://github.com/minio/minio/blob/master/docs/kms/README.md).

Instead of configuring an external KMS you can start with a single key by
setting the env. variable `MINIO_KMS_SECRET_KEY`. It expects the following
format:

```sh
MINIO_KMS_SECRET_KEY=<key-name>:<base64-value>

## Impulsado por

FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app
```

### Applications plus larges

Si vous avez suivi la section sur la création d' [Applications avec plusieurs fichiers](../tutorial/bigger-applications.md){.internal-link target=_blank}, votre `Dockerfile` pourrait ressembler à ceci :

```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app/app
```

### Raspberry Pi et autres architectures

## Instala dependencias { #install-dependencies }

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo e instalar `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

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

Si tienes una versión anterior, obtendrás errores al intentar usar `Annotated`.

Asegúrate de [Actualizar la versión de FastAPI](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} al menos a la 0.95.1 antes de usar `Annotated`.
