ここで、`/unicorns/yolo`をリクエストすると、*path operation*は`UnicornException`を`raise`します。

しかし、これは`unicorn_exception_handler`で処理されます。

そのため、HTTPステータスコードが`418`で、JSONの内容が以下のような明確なエラーを受け取ることになります:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

また、`from starlette.requests import Request`と`from starlette.responses import JSONResponse`を使用することもできます。

### Don't worry about style { #dont-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.

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

FastAPI 😑 🛠️ *➡ 🛠️* 💪 👀 💖:

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

👀 🔀 `requests.get(...)` & `@app.get(...)`.

Відповідна операція *роуту* API FastAPI може виглядати так:

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

Зверніть увагу на схожість у `requests.get(...)` і `@app.get(...)`.
