それらはクライアントに返される前に適切な値 (この場合は文字列) に変換されます。

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```

クライアントは以下の様なJSONレスポンスを得ます:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## パスを含んだパスパラメータ

パス `/files/{file_path}` となる *path operation* を持っているとしましょう。

ただし、 `home/johndoe/myfile.txt` のような*パス*を含んだ `file_path` が必要です。

Bunun FastAPI'deki API <abbr title="Yol İşlemi: Path Operation">*yol işlemi*</abbr> şöyle görünür:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World!"}
```

`requests.get(...)` ile `@app.get(...)` arasındaki benzerliklere bakın.

/// check | "**FastAPI**'a nasıl ilham verdi?"

* Basit ve sezgisel bir API'ya sahip olmalı.

response = requests.get("http://example.com/some/url")
```

Противоположная *операция пути* в FastAPI может выглядеть следующим образом:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Глядите, как похоже `requests.get(...)` и `@app.get(...)`.

/// check | "Идеи для **FastAPI**"

* Должен быть простой и понятный API.

                // + 64 byte header
                // + 8 byte query response overhead
                // + 110 bytes entry
                // -> 1022 predicted message size <= 1023 maximum buffer size
                // 112 bytes to alignment
                // -> aligned to 1024 > 1023 maximum buffer size

                // 110 byte entry = 16 byte name = 8 char length

### Don't worry about style

* Don't worry too much about things like commit message styles, I will squash and merge customizing the commit manually.

* Also don't worry about style rules, there are already automatized tools checking that.
