**FastAPI** 支持同时声明**请求体**、**路径参数**和**查询参数**。

**FastAPI** 能够正确识别这三种参数，并从正确的位置获取数据。

{* ../../docs_src/body/tutorial004_py310.py hl[16] *}

函数参数按如下规则进行识别：

- **路径**中声明了相同参数的参数，是路径参数
- 类型是（`int`、`float`、`str`、`bool` 等）**单类型**的参数，是**查询**参数
- 类型是 **Pydantic 模型**的参数，是**请求体**

/// note | 笔记

因为默认值是 `None`， FastAPI 会把 `q` 当作可选参数。

FastAPI 不使用 `Optional[str]` 中的 `Optional`， 但 `Optional` 可以让编辑器提供更好的支持，并检测错误。

> The admin user running this command needs the "admin:SetTier" and "admin:ListTier" permissions if not running as root.

Using above tier, set up a lifecycle rule with transition:

```
 mc ilm add --expiry-days 365 --transition-days 45 --storage-class "AZURETIER" myminio/srcbucket
```

- `aws:EpochTime` - This is the date in epoch or Unix time, for use with date/time conditions.
- `aws:PrincipalType` - This value indicates whether the principal is an account (Root credential), user (MinIO user), or assumed role (STS)
- `aws:SecureTransport` - This is a Boolean value that represents whether the request was sent over TLS.
