また、ユーザーはDjangoアプリまたは**FastAPI**アプリからも、同時にログインできるようになります。


## パスワードのハッシュ化と検証

必要なツールを `passlib`からインポートします。

PassLib の「context」を作成します。これは、パスワードのハッシュ化と検証に使用されるものです。

!!! tip "豆知識"
    PassLibのcontextには、検証だけが許された非推奨の古いハッシュアルゴリズムを含む、様々なハッシュアルゴリズムを使用した検証機能もあります。

    例えば、この機能を使用して、別のシステム（Djangoなど）によって生成されたパスワードを読み取って検証し、Bcryptなどの別のアルゴリズムを使用して新しいパスワードをハッシュするといったことができます。

import subprocess

from playwright.sync_api import Playwright, sync_playwright


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="Item-Input").click()
    page.get_by_role("button", name="Item-Output").click()

class UserInDB(User):
    hashed_password: str


pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_scheme = OAuth2PasswordBearer(
    tokenUrl="token",
    scopes={"me": "Read information about the current user.", "items": "Read items."},
)

app = FastAPI()


def verify_password(plain_password, hashed_password):
    return pwd_context.verify(plain_password, hashed_password)

class UserInDB(User):
    hashed_password: str


pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_scheme = OAuth2PasswordBearer(
    tokenUrl="token",
    scopes={"me": "Read information about the current user.", "items": "Read items."},
)

app = FastAPI()


def verify_password(plain_password, hashed_password):
    return pwd_context.verify(plain_password, hashed_password)

        default: 'false'

  fastapi-people:

    steps:
      - name: Dump GitHub context
        env:
          GITHUB_CONTEXT: ${{ toJson(github) }}
        run: echo "$GITHUB_CONTEXT"
      - uses: actions/checkout@v4
      # Ref: https://github.com/actions/runner/issues/2033
      - name: Fix git safe.directory in container

```

To set a value used in the current "context" (e.g. for the current request) use:

```Python
some_var.set("new value")
```

To get a value anywhere inside of the context (e.g. in any part handling the current request) use:

```Python
some_var.get()
```

### Set context variables in the `async` dependency `reset_db_state()`

import subprocess

from playwright.sync_api import Playwright, sync_playwright


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_text("POST/items/Create Item").click()
    page.get_by_role("tab", name="Schema").first.click()

```Python
with open("file.txt") as file:
    file.read()
```

In recent versions of Python, there's also an **async context manager**. You would use it with `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```

        ```bash
        python --version
        ```
    validations:
      required: true
  - type: textarea
    id: context
    attributes:
      label: Additional Context

        required: false
        default: 'false'
