This last path operation will have the combination of tags: `["items", "custom"]`.

And it will also have both responses in the documentation, one for `404` and one for `403`.

///

## The main `FastAPI`

Now, let's see the module at `app/main.py`.

Here's where you import and use the class `FastAPI`.

		// mean that authentication succeeded, but another
		// side-channel check has failed, we shall take
		// the client offline in such situations.
		// generally all implementations should simply return
		// 403, but in situations where there is a dependency
		// with the caller to take the client offline purpose
		// fully it should make sure to respond with '412'
		// instead, see cmd/storage-rest-server.go for ideas.

```

/// tip | "Tipp"

Diese letzte Pfadoperation wird eine Kombination von Tags haben: `["items", "custom"]`.

Und sie wird auch beide Responses in der Dokumentation haben, eine für `404` und eine für `403`.

///

## Das Haupt-`FastAPI`.

Sehen wir uns nun das Modul unter `app/main.py` an.

Hier importieren und verwenden Sie die Klasse `FastAPI`.

```

/// tip | "Dica"

Esta última operação de caminho terá a combinação de tags: `["items", "custom"]`.

E também terá ambas as respostas na documentação, uma para `404` e uma para `403`.

///

## O principal `FastAPI`

Agora, vamos ver o módulo em `app/main.py`.

Aqui é onde você importa e usa a classe `FastAPI`.

Este será o arquivo principal em seu aplicativo que une tudo.

最后的这个路径操作将包含标签的组合：`["items"，"custom"]`。

并且在文档中也会有两个响应，一个用于 `404`，一个用于 `403`。

## `FastAPI` 主体

现在，让我们来看看位于 `app/main.py` 的模块。

在这里你导入并使用 `FastAPI` 类。

这将是你的应用程序中将所有内容联结在一起的主文件。

并且由于你的大部分逻辑现在都存在于其自己的特定模块中，因此主文件的内容将非常简单。
