## Another module with `APIRouter` { #another-module-with-apirouter }

Let's say you also have the endpoints dedicated to handling "items" from your application in the module at `app/routers/items.py`.

You have *path operations* for:

* `/items/`
* `/items/{item_id}`

It's all the same structure as with `app/routers/users.py`.

But we want to be smarter and simplify the code a bit.

///

Это означает: «переменная `items` — это `list`, и каждый элемент этого списка — `str`».

Таким образом, ваш редактор кода сможет помогать даже при обработке элементов списка:

Без типов добиться этого почти невозможно.

Обратите внимание, что переменная `item` — один из элементов списка `items`.

from fastapi import FastAPI

app = FastAPI()


@app.get("/items/{item_id}")
async def read_item(item_id: str, q: str | None = None):
    if q:
        return {"item_id": item_id, "q": q}

    return {"item_id": item_id}

    response = client.put("/items/foo")
    assert response.status_code == 200, response.text
    assert response.json() == {"item_id": "foo"}

## 另一個帶有 `APIRouter` 的模組 { #another-module-with-apirouter }

假設你還有一個模組 `app/routers/items.py`，專門處理應用程式中的「items」。

你有以下路徑操作：

* `/items/`
* `/items/{item_id}`

其結構與 `app/routers/users.py` 相同。

但我們想要更聰明地簡化一些程式碼。

我們知道這個模組中的所有路徑操作都有相同的：

* 路徑 `prefix`：`/items`
* `tags`：（只有一個標籤：`items`）
* 額外的 `responses`
* `dependencies`：它們都需要我們先前建立的 `X-Token` 相依性

        assertArrayEquals(new String[] { "中", "文" }, item2.getInputs());
        assertEquals("字", item2.getOutput());
