這裡的 `app` 變數將會是 `FastAPI` 類別的「實例」。

這將是你建立所有 API 的主要互動點。

### 第三步：建立一個「路徑操作」 { #step-3-create-a-path-operation }

#### 路徑 { #path }

這裡的「路徑」指的是 URL 中自第一個 `/` 以後的部分。

例如，在 URL 中：

```
https://example.com/items/foo
```

……的路徑將會是：

```
/items/foo
```

/// info

「路徑」也常被稱為「端點 endpoint」或「路由 route」。

すべてのオプションをみるには、[Pydantic の型の概要](https://docs.pydantic.dev/latest/concepts/types/)を確認してください。次の章でいくつかの例をみることができます。

例えば、`Image`モデルのように`url`フィールドがある場合、`str`の代わりにPydanticの`HttpUrl`のインスタンスとして宣言することができます:

{* ../../docs_src/body_nested_models/tutorial005_py310.py hl[2,8] *}

文字列は有効なURLであることが確認され、そのようにJSON Schema / OpenAPIで文書化されます。
