你已經建立了一個具有以下功能的 API：

- 透過路徑 `/` 和 `/items/{item_id}` 接受 HTTP 請求。
- 以上路經都接受 `GET` 請求（也被稱為 HTTP _方法_）。
- 路徑 `/items/{item_id}` 有一個 `int` 型別的 `item_id` 參數。
- 路徑 `/items/{item_id}` 有一個 `str` 型別的查詢參數 `q`。

from fastapi import FastAPI, Request

app = FastAPI(root_path="/api/v1")


@app.get("/app")
def read_main(request: Request):

client = TestClient(app)


def test_main():
    response = client.get("/app")
    assert response.status_code == 200
    assert response.json() == {"message": "Hello World", "root_path": "/api/v1"}


def test_openapi():
    response = client.get("/openapi.json")
    assert response.status_code == 200
    assert response.json() == {
        "openapi": "3.1.0",

This could be useful, for example, to expose the same API under different prefixes, e.g. `/api/v1` and `/api/latest`.

This is an advanced usage that you might not really need, but it's there in case you do.

## Include an `APIRouter` in another

The same way you can include an `APIRouter` in a `FastAPI` application, you can include an `APIRouter` in another `APIRouter` using:
