Pour déclarer ces types et les types internes, on utilise le module standard de Python `typing`.

Il existe spécialement pour supporter ces annotations de types.

#### `List`

Par exemple, définissons une variable comme `list` de `str`.

**FastAPI** créera l'objet de type `BackgroundTasks` pour vous et le passera comme paramètre.

## Créer une fonction de tâche

Une fonction à exécuter comme tâche d'arrière-plan est juste une fonction standard qui peut recevoir des paramètres.

Elle peut être une fonction asynchrone (`async def`) ou une fonction normale (`def`), **FastAPI** saura la gérer correctement.

# CI Pipeline Configuration

## Open & import the project

In your IDEA, `File` - `Open`, select `.teamcity/pom.xml`, `import as project`, and you'll have a Maven project.

## Project structure

Mostly a standard Maven project structure. The entry point `settings.kts` defines the TeamCity project.

There are 3 subprojects in the TeamCity project hierarchy: `Check` for Gradle builds, `Promotion` for releasing Gradle versions, `Util` for miscellaneous utilities.

......以上安装还包括了 `uvicorn`，你可以将其用作运行代码的服务器。

/// note

你也可以分开来安装。

假如你想将应用程序部署到生产环境，你可能要执行以下操作：

```
pip install fastapi
```

并且安装`uvicorn`来作为服务器：

```
pip install "uvicorn[standard]"
```

然后对你想使用的每个可选依赖项也执行相同的操作。

request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.

Latency sensitive applications may notice an increased latency due to a request to the external plugin upon every authenticated request to MinIO. User are advised to provision their infrastructure such that latency and performance...
