```Python hl_lines="5-10  16  21" title="app/routers/items.py"
{!../../docs_src/bigger_applications/app/routers/items.py!}
```

由于每个*路径操作*的路径都必须以 `/` 开头，例如：

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

...前缀不能以 `/` 作为结尾。

因此，本例中的前缀为 `/items`。

我们还可以添加一个 `tags` 列表和额外的 `responses` 列表，这些参数将应用于此路由器中包含的所有*路径操作*。
