사용 방법은 매우 간단합니다. 예를 들어 `GET` 요청을 하려면 다음처럼 작성합니다:

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

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.

              close(1010, "unexpected Sec-WebSocket-Extensions in response header")
            }
          }

          // Process all web socket messages.
          val name = "$okHttpName WebSocket ${request.url.redact()}"
          initReaderAndWriter(
            name = name,
            socket = socket.asBufferedSocket(),
            client = true,
          )
          loopReader(response)
        }

De esta manera la aplicación podrá saber cuál es su propia URL pública, si está usando HTTPS, el dominio, etc.

Esto sería útil, por ejemplo, para manejar correctamente redirecciones.

Dans OAuth2, un « scope » est simplement une chaîne qui déclare une permission spécifique requise.

Peu importe s’il contient d’autres caractères comme `:` ou si c’est une URL.

Ces détails dépendent de l’implémentation.

Pour OAuth2, ce ne sont que des chaînes.

De cette façon, l'application sera en mesure de savoir quelle est sa propre URL publique, si elle utilise HTTPS, le domaine, etc.

Cela serait utile, par exemple, pour gérer correctement les redirections.
