Buna karşılık bir FastAPI API *path operation*’ı şöyle olabilir:

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

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

Соответствующая в FastAPI API-операция пути могла бы выглядеть так:

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

Посмотрите, насколько похожи `requests.get(...)` и `@app.get(...)`.
