### Dockerfile

同じプロジェクト・ディレクトリに`Dockerfile`というファイルを作成します：

```{ .dockerfile .annotate }
# (1)
FROM python:3.9

# (2)

                + "<field name=\"name\"><list><item>鈴木太郎</item><item>佐藤二朗</item><item>田中花子</item></list></field>\n"//
                + "<field name=\"access\"><list><item></item><item>http://www.taro.com/</item><item>******@****.***</item><item>090-xxxx-xxxx</item></list></field>\n"//
                + "<field name=\"image\"><list><item>taro.png</item><item>jiro.png</item><item>hanako.png</item></list></field>\n"//

        from pydantic import BaseModel

        class Item(BaseModel):
            name: str
            description: str | None = None

        app = FastAPI()
        router = APIRouter()

        @router.put("/items/{item_id}")
        def replace_item(item_id: str, item: Item):
            return {"message": "Item replaced", "id": item_id}

        app.include_router(router)
        ```

                    "properties": {
                        "loc": {
                            "title": "Location",
                            "type": "array",

                                "anyOf": [{"type": "string"}, {"type": "integer"}]
                            },

                        "msg": {"title": "Message", "type": "string"},

Por exemplo, vamos supor que você possua 4 endpoints na sua API (*operações de rota*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

Você poderia adicionar diferentes requisitos de permissão para cada um deles utilizando apenas dependências e sub-dependências:

from fastapi import FastAPI

app = FastAPI(docs_url="/documentation", redoc_url=None)


@app.get("/items/")
async def read_items():

                                        <td><c:forEach var="item"
                                                       items="${protocolSchemeItems}">
                                            <c:if test="${protocolScheme==item.value}">${f:h(item.label)}</c:if>
                                        </c:forEach> <la:hidden property="protocolScheme"/></td>
