# パスワードとBearerによるシンプルなOAuth2 { #simple-oauth2-with-password-and-bearer }

前章から発展させて、完全なセキュリティフローに必要な不足部分を追加していきます。

## `username` と `password` を取得する { #get-the-username-and-password }

`username` と `password` を取得するために **FastAPI** のセキュリティユーティリティを使います。

OAuth2 では、「password flow」（ここで使用するフロー）を使う場合、クライアント/ユーザーはフォームデータとして `username` と `password` フィールドを送信する必要があります。

しかも、フィールド名はこの通りでなければなりません。つまり、`user-name` や `email` では動作しません。

# Using the Request Directly { #using-the-request-directly }

Up to now, you have been declaring the parts of the request that you need with their types.

Taking data from:

* The path as parameters.
* Headers.
* Cookies.
* etc.

And by doing so, **FastAPI** is validating that data, converting it and generating documentation for your API automatically.

But there are situations where you might need to access the `Request` object directly.

Cache Miss will be typical if the item has not been read from the network, is uncacheable, or is past it's
lifetime based on Response cache headers.

 - CallStart
 - **CacheMiss**
 - ProxySelectStart
 - ... Standard Events ...
 - CallEnd

### Conditional Cache Hit

        final List<StemmerOverrideItem> itemList = new ArrayList<>();
        try (BufferedReader reader = new BufferedReader(new InputStreamReader(in, Constants.UTF_8))) {
            long id = 0;
            String line = null;
            while ((line = reader.readLine()) != null) {
                // Remove comments

    * параметра запроса.
    * HTTP-заголовка.
    * cookie.
* `http`: стандартные системы аутентификации по HTTP, включая:
    * `bearer`: HTTP-заголовок `Authorization` со значением `Bearer ` плюс токен. Это унаследовано от OAuth2.
    * Базовая аутентификация по HTTP.
    * HTTP Digest и т.д.
* `oauth2`: все способы OAuth2 для обеспечения безопасности (называются «потоками»).
