     还有其他文件格式和工具来定义和安装依赖项。

     我将在下面的部分中向你展示一个使用 Poetry 的示例。 👇

### 创建 **FastAPI** 代码

* 创建`app`目录并进入。
* 创建一个空文件`__init__.py`。
* 创建一个 `main.py` 文件：



```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

To declare those types and the internal types, you can use the standard Python module `typing`. It exists specifically to support these type hints.

#### Newer versions of Python

The syntax using `typing` is **compatible** with all versions, from Python 3.6 to the latest ones, including Python 3.9, Python 3.10, etc.

Troubleshoot workloads that crash on startup by creating a copy of the pod that uses a different container image or command.
Troubleshoot distroless containers by adding a new container with debugging tools, either in a new copy of the pod or using an ephemeral container. (Ephemeral containers are an alpha feature that are not enabled by default.)

## Testing

- Fix pod list return value of `framework.WaitForPodsWithLabelRunningReady` ([#78687](https://github.com/kubernetes/kubernetes/pull/78687), [@pohly](https://github.com/pohly))
- Adding `TerminationGracePeriodSeconds` to the test framework API ([#82170](https://github.com/kubernetes/kubernetes/pull/82170), [@vivekbagade](https://github.com/vivekbagade))

```

!!! note
    Notice that as we communicate with the database using `await`, the *path operation function* is declared with `async`.

### Notice the `response_model=List[Note]`

It uses `typing.List`.

That documents (and validates, serializes, filters) the output data, as a `list` of `Note`s.

## Create notes

Create the *path operation function* to create notes:

```Python hl_lines="61-65"

## About security, APIs, and docs

Hiding your documentation user interfaces in production *shouldn't* be the way to protect your API.

That doesn't add any extra security to your API, the *path operations* will still be available where they are.

If there's a security flaw in your code, it will still exist.

### Импортируйте `List` из модуля typing

В Python 3.9 и выше вы можете использовать стандартный тип `list` для объявления аннотаций типов, как мы увидим ниже. 💡

Но в версиях Python до 3.9 (начиная с 3.6) сначала вам необходимо импортировать `List` из стандартного модуля `typing` в Python:

```Python hl_lines="1"
{!> ../../../docs_src/body_nested_models/tutorial002.py!}
```

require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically,
with a *minimum* of 4 drives per MinIO server. See [MinIO Erasure Code Overview](https://min.io/docs/minio/linux/operations/concepts/erasure-coding.html)
for more complete documentation.

### Stable

containers provide isolated application execution environment, orchestration platforms allow seamless scaling by helping replicate and manage containers. MinIO extends this by adding isolated storage environment for each tenant.

MinIO is built ground up on the cloud-native premise. With features like erasure-coding, distributed and shared setup, it focuses only on storage and does it very well. While, it can be scaled by just replicating MinIO instances per tenant via an orchestration platform....
