<summary>關於指令 <code>uvicorn main:app --reload</code>...</summary>

該指令 `uvicorn main:app` 指的是：

- `main`：`main.py` 檔案（一個 python 的 "模組"）。
- `app`：在 `main.py` 檔案中，使用 `app = FastAPI()` 建立的物件。
- `--reload`：程式碼更改後會自動重新啟動，請僅在開發時使用此參數。

</details>

### 檢查

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


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">
<summary>Ou utilisez <code>async def</code> ...</summary>

Si votre code utilise `async` / `await`, utilisez `async def` :

```Python hl_lines="9  14"
from typing import Union

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


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">
<summary>Tàbí lò <code>async def</code>...</summary>

Tí kóòdù rẹ̀ bá ń lò `async` / `await`, lò `async def`:

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

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


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">
<summary>همچنین می‌توانید از <code>async def</code>... نیز استفاده کنید</summary>

اگر در کدتان از `async` / `await` استفاده می‌کنید، از `async def` برای تعریف تابع خود استفاده کنید:
