# Güvenlik { #security }

Güvenlik, authentication ve authorization’ı ele almanın birçok yolu vardır.

Ve bu konu genellikle karmaşık ve "zor"dur.

Birçok framework ve sistemde yalnızca security ve authentication’ı yönetmek bile ciddi miktarda emek ve kod gerektirir (çoğu durumda yazılan toplam kodun %50’si veya daha fazlası olabilir).

from typing import Annotated

from fastapi import FastAPI, HTTPException, Security
from fastapi.security import (
    OAuth2PasswordBearer,
    SecurityScopes,
)
from fastapi.testclient import TestClient

app = FastAPI()

oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")


def process_auth(
    credentials: Annotated[str | None, Security(oauth2_scheme)],
    security_scopes: SecurityScopes,
):

# Simple OAuth2 with Password and Bearer { #simple-oauth2-with-password-and-bearer }

Now let's build from the previous chapter and add the missing parts to have a complete security flow.

## Get the `username` and `password` { #get-the-username-and-password }

We are going to use **FastAPI** security utilities to get the `username` and `password`.

from fastapi import FastAPI, Security
from fastapi.security import HTTPAuthorizationCredentials, HTTPBearer
from fastapi.testclient import TestClient
from inline_snapshot import snapshot

app = FastAPI()

security = HTTPBearer()


@app.get("/users/me")
def read_current_user(credentials: HTTPAuthorizationCredentials = Security(security)):
    return {"scheme": credentials.scheme, "credentials": credentials.credentials}

from fastapi import FastAPI, Security
from fastapi.security import HTTPAuthorizationCredentials, HTTPDigest
from fastapi.testclient import TestClient
from inline_snapshot import snapshot

app = FastAPI()

security = HTTPDigest(description="HTTPDigest scheme")


@app.get("/users/me")
def read_current_user(credentials: HTTPAuthorizationCredentials = Security(security)):
    return {"scheme": credentials.scheme, "credentials": credentials.credentials}

## *경로 처리*와 의존성에서 스코프 선언하기 { #declare-scopes-in-path-operations-and-dependencies }

이제 `/users/me/items/`에 대한 *경로 처리*가 스코프 `items`를 요구한다고 선언합니다.

이를 위해 `fastapi`에서 `Security`를 import하여 사용합니다.

`Security`는 (`Depends`처럼) 의존성을 선언하는 데 사용할 수 있지만, `Security`는 스코프(문자열) 목록을 받는 `scopes` 매개변수도 받습니다.

security = HTTPBearer(description="HTTP Bearer token scheme")
