Como o path de cada *operação de rota* tem que começar com `/`, como em:

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

...o prefixo não deve incluir um `/` final.

Então, o prefixo neste caso é `/items`.

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

La operación de path equivalente en FastAPI podría verse como:

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

Mira las similitudes entre `requests.get(...)` y `@app.get(...)`.

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

A contra-parte na aplicação FastAPI, a operação de rota, poderia ficar assim:

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

Veja as similaridades em `requests.get(...)` e `@app.get(...)`.

```Python

Die entsprechende *Pfadoperation* der FastAPI-API könnte wie folgt aussehen:

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

Sehen Sie sich die Ähnlichkeiten in `requests.get(...)` und `@app.get(...)` an.

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

L’opération de chemin d'accès correspondante dans **FastAPI** pourrait ressembler à ceci :

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

Notez les similitudes entre `requests.get(...)` et `@app.get(...)`.

* Avoir une API simple et intuitive.

```Python

이에 대응하는 FastAPI의 API *경로 처리*는 다음과 같이 보일 수 있습니다:

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

`requests.get(...)`와 `@app.get(...)`의 유사성을 확인해 보세요.

各 *path operation* のパスは次のように `/` で始める必要があるため:

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

...prefix の末尾に `/` を含めてはいけません。

この場合の prefix は `/items` です。

また、`tags` のリストや追加の `responses` を、このルーターに含まれるすべての *path operations* に適用するよう追加できます。
