`from starlette.requests import Request` を使用することもできます。

**FastAPI**は、開発者の便利のためにこれを提供していますが、Starletteから直接きています。

///

### `response` の前後 { #before-and-after-the-response }

*path operation* が `request` を受け取る前に、 `request` とともに実行されるコードを追加できます。

また `response` が生成された後、それを返す前にも追加できます。

例えば、リクエストの処理とレスポンスの生成にかかった秒数を含むカスタムヘッダー `X-Process-Time` を追加できます:

	// Assert whether the connection pool of tx is successfully converted to the *gorm.PreparedStmtDB type.
	AssertEqual(t, ok, true)
	// Assert whether the number of statement keys stored in the PreparedStmtDB is 0 after 40 seconds.
	// If it is not 0, it means the statements in the cache have not expired as expected.
	AssertEqual(t, len(conn.Stmts.Keys()), 0)

}
