여러분은 타입을 이용한 표준 파이썬을 다음과 같이 적을 수 있습니다:

```Python
from datetime import date

from pydantic import BaseModel

# 변수를 str로 선언
# 그 후 함수 안에서 편집기 지원을 받으세요
def main(user_id: str):
    return user_id


# Pydantic 모델
class User(BaseModel):
    id: int
    name: str
    joined: date
```

위의 코드는 다음과 같이 사용될 수 있습니다:

```Python

/// tip

Notice that here as we are using standard `open()` that doesn't support `async` and `await`, we declare the path operation with normal `def`.

///

### `FileResponse` { #fileresponse }

Asynchronously streams a file as the response.

Takes a different set of arguments to instantiate than the other response types:

```Python
def get_current_user(token: str):
    # authenticate user
    return User()


@app.get("/items/")
def read_items(user: User = Depends(get_current_user)):
    ...


@app.post("/items/")
def create_item(*, user: User = Depends(get_current_user), item: Item):
    ...


@app.get("/items/{item_id}")

{!../../docs_src/bigger_applications/app/routers/items.py!}
```

As the path of each *path operation* has to start with `/`, like in:

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

...the prefix must not include a final `/`.

So, the prefix in this case is `/items`.

* Create a `main.py` file with:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

### Dockerfile { #dockerfile }

* Crie um arquivo `main.py` com:

```Python
from typing import Optional

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

### Dockerfile

/// tip | Dica

Perceba que aqui estamos utilizando o `open()` da biblioteca padrão que não suporta `async` e `await`, e declaramos a operação de rota com o `def` básico.

///

### `FileResponse`

Envia um arquivo  de forma assíncrona e contínua (stream).
*
Recebe um conjunto de argumentos do construtor diferente dos outros tipos de resposta:

```Python
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.

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

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?

* Создайте файл `main.py` и заполните его:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```
