Gardez à l'esprit que le serveur (Uvicorn) n'utilisera ce `root_path` que pour le transmettre à l'application.

Mais si vous allez avec votre navigateur sur [http://127.0.0.1:8000/app](http://127.0.0.1:8000/app), vous verrez la réponse normale :

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

Donc, il ne s'attendra pas à être accessible à `http://127.0.0.1:8000/api/v1/app`.

            "input": "plumbus",

## Desactivar la conversión de guiones bajos { #disable-convert-underscores }

De la misma forma que con los parámetros de header normales, cuando tienes caracteres de guion bajo en los nombres de los parámetros, se **convierten automáticamente en guiones**.

- Follow the existing Japanese style: short, descriptive headings (often noun phrases), e.g. 「チェック」.
- Do not add a trailing period at the end of headings.

### Quotes

- Prefer Japanese corner brackets 「」 in normal prose when quoting a term.
- Do not change quotes inside inline code, code blocks, URLs, or file paths.

### Ellipsis

- Keep ellipsis style consistent with existing Japanese docs (commonly `...`).

        }

        return null;

It is just a standard function that can receive parameters.

It can be an `async def` or normal `def` function, **FastAPI** will know how to handle it correctly.

In this case, the task function will write to a file (simulating sending an email).

And as the write operation doesn't use `async` and `await`, we define the function with normal `def`:

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[6:9] *}

Also, HTTP headers are case-insensitive, so, you can declare them with standard Python style (also known as "snake_case").

So, you can use `user_agent` as you normally would in Python code, instead of needing to capitalize the first letters as `User_Agent` or something similar.

        value = "\"complex \"\"test\"\" value\",normal,\"another \"\"escaped\"\"\"";
        result = KuromojiCSVUtil.parse(value);
        assertEquals(3, result.length);
        assertEquals("\"complex \"test\" value\"", result[0]);
        assertEquals("normal", result[1]);
        assertEquals("\"another \"\"escaped\"\"\"", result[2]);

# GraphQL { #graphql }

**FastAPI**, **ASGI** standardını temel aldığı için ASGI ile uyumlu herhangi bir **GraphQL** kütüphanesini entegre etmek oldukça kolaydır.

Aynı uygulama içinde normal FastAPI *path operation*'larını GraphQL ile birlikte kullanabilirsiniz.

/// tip | İpucu

**GraphQL** bazı çok özel kullanım senaryolarını çözer.

Yaygın **web API**'lerle karşılaştırıldığında **avantajları** ve **dezavantajları** vardır.
