Na verdade, é comum utilizar Requests dentro de uma aplicação FastAPI.

Ainda assim, o FastAPI tirou bastante inspiração do Requests.

**Requests** é uma biblioteca para interagir com APIs (como um cliente), enquanto **FastAPI** é uma biblioteca para construir APIs (como um servidor).

Eles estão, mais ou menos, em pontas opostas, complementando-se.

             following code:

             <u style="text-decoration-style:solid">from </u><u style="text-decoration-style:solid"><b>main</b></u><u style="text-decoration-style:solid"> import </u><u style="text-decoration-style:solid"><b>app</b></u>

             following code:

             <u style="text-decoration-style:solid">from </u><u style="text-decoration-style:solid"><b>main</b></u><u style="text-decoration-style:solid"> import </u><u style="text-decoration-style:solid"><b>app</b></u>

Das `fastapi`-CLI versucht automatisch, die auszuführende FastAPI-App zu erkennen, und geht davon aus, dass es sich um ein Objekt namens `app` in einer Datei `main.py` handelt (oder ein paar weitere Varianten).

Sie können aber auch explizit konfigurieren, welche App verwendet werden soll.

## Den App-`entrypoint` in `pyproject.toml` konfigurieren { #configure-the-app-entrypoint-in-pyproject-toml }

The `fastapi` CLI will try to detect automatically the FastAPI app to run, assuming it's an object called `app` in a file `main.py` (or a couple other variants).

But you can configure explicitly the app to use.

## Configure the app `entrypoint` in `pyproject.toml` { #configure-the-app-entrypoint-in-pyproject-toml }

You can configure where your app is located in a `pyproject.toml` file like:

```toml
[tool.fastapi]

             following code:

             <u style="text-decoration-style:solid">from </u><u style="text-decoration-style:solid"><b>main</b></u><u style="text-decoration-style:solid"> import </u><u style="text-decoration-style:solid"><b>app</b></u>

             following code:

             <u style="text-decoration-style:solid">from </u><u style="text-decoration-style:solid"><b>main</b></u><u style="text-decoration-style:solid"> import </u><u style="text-decoration-style:solid"><b>app</b></u>

`fastapi` CLI 會嘗試自動偵測要執行的 FastAPI 應用程式，預設假設它是檔案 `main.py` 中名為 `app` 的物件（或其他幾種變體）。

不過你也可以明確設定要使用的 app。

## 在 `pyproject.toml` 中設定應用程式的 `entrypoint` { #configure-the-app-entrypoint-in-pyproject-toml }

你可以在 `pyproject.toml` 檔案中指定你的 app 位置，例如：

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

這個 `entrypoint` 會告訴 `fastapi` 指令應該像這樣匯入 app：

```python
from main import app
```

如果你的程式碼結構是這樣：

```
.

             following code:

             <u style="text-decoration-style:solid">from </u><u style="text-decoration-style:solid"><b>main</b></u><u style="text-decoration-style:solid"> import </u><u style="text-decoration-style:solid"><b>app</b></u>

             the following code:

             <u style="text-decoration-style:solid">from </u><u style="text-decoration-style:solid"><b>main</b></u><u style="text-decoration-style:solid"> import </u><u style="text-decoration-style:solid"><b>app</b></u>
