## 在 `pyproject.toml` 設定 `entrypoint` { #configure-the-entrypoint-in-pyproject-toml }

因為你的 FastAPI `app` 物件位在 `app/main.py`，你可以在 `pyproject.toml` 檔案中這樣設定 `entrypoint`：

```toml
[tool.fastapi]
entrypoint = "app.main:app"
```

這等同於這樣匯入：

```python
from app.main import app
```

如此一來 `fastapi` 指令就會知道去哪裡找到你的 app。

/// Note | 注意

你也可以把路徑直接傳給指令，例如：

bom

// bond : ShortDot SA
// https://www.iana.org/domains/root/db/bond.html
bond

// boo : Charleston Road Registry Inc.
// https://www.iana.org/domains/root/db/boo.html
boo

// book : Amazon Registry Services, Inc.
// https://www.iana.org/domains/root/db/book.html
book

// booking : Booking.com B.V.
// https://www.iana.org/domains/root/db/booking.html
booking

Comme votre objet FastAPI `app` vit dans `app/main.py`, vous pouvez configurer l'`entrypoint` dans votre fichier `pyproject.toml` comme ceci :

```toml
[tool.fastapi]
entrypoint = "app.main:app"
```

ce qui équivaut à importer ainsi :

```python
from app.main import app
```

De cette façon, la commande `fastapi` saura où trouver votre app.

Como tu objeto `app` de FastAPI vive en `app/main.py`, puedes configurar el `entrypoint` en tu archivo `pyproject.toml` así:

```toml
[tool.fastapi]
entrypoint = "app.main:app"
```

que es equivalente a importar como:

```python
from app.main import app
```

De esa manera el comando `fastapi` sabrá dónde encontrar tu app.

Como seu objeto `app` do FastAPI fica em `app/main.py`, você pode configurar o `entrypoint` no seu arquivo `pyproject.toml` assim:

```toml
[tool.fastapi]
entrypoint = "app.main:app"

isso é equivalente a importar como:

```python
from app.main import app
```

Dessa forma o comando `fastapi` saberá onde encontrar sua aplicação.
