## どのように動作するか

リクエストの中に`Authorization`ヘッダーを探しに行き、その値が`Bearer`と何らかのトークンを含んでいるかどうかをチェックし、そのトークンを`str`として返します。

もし`Authorization`ヘッダーが見つからなかったり、値が`Bearer`トークンを持っていなかったりすると、401 ステータスコードエラー (`UNAUTHORIZED`) で直接応答します。

トークンが存在するかどうかをチェックしてエラーを返す必要はありません。関数が実行された場合、そのトークンに`str`が含まれているか確認できます。

 *  Fix: Don't use brackets formatting IPv6 host names in MockWebServer.
 *  Fix: Don't permit cache iterators to remove entries that are being written.


## Version 4.0.1

_2019-07-10_

 *  Fix: Tolerate null-hostile lists in public API. Lists created with `List.of(...)` don't like it
    when you call `contains(null)` on them!

### Handling authentication ([.kt][AuthenticateKotlin], [.java][AuthenticateJava])

OkHttp can automatically retry unauthenticated requests. When a response is `401 Not Authorized`, an `Authenticator` is asked to supply credentials. Implementations should build a new request that includes the missing credentials. If no credentials are available, return null to skip the retry.
