### [Requests](https://requests.readthedocs.io) { #requests }

**FastAPI** is not actually an alternative to **Requests**. Their scope is very different.

The top-level scripts and utility scripts should be fairly well-documented. Here
is a brief explanation of how they tie together:

1.  `envs/*` are lists of variables made with bash syntax. A user must set a
    `TFCI` env param pointing to a list of `env` files.
2.  `utilities/setup.sh`, initialized by all top-level scripts, reads and sets
    values from those `TFCI` paths.
    -   `set -a` / `set -o allexport` exports the variables from `env` files so

        assertEquals(LongMath.pow(i, exp), valueOf(i).pow(exp).longValue());
      }
    }
  }

  @GwtIncompatible // TODO

    checkState(ySumOfSquaresOfDeltas > 0.0);
    // The product of two positive numbers can be zero if the multiplication underflowed. We
    // force a positive value by effectively rounding up to MIN_VALUE.
    double productOfSumsOfSquaresOfDeltas =
        ensurePositive(xSumOfSquaresOfDeltas * ySumOfSquaresOfDeltas);
    return ensureInUnitRange(sumOfProductsOfDeltas / Math.sqrt(productOfSumsOfSquaresOfDeltas));

### カスタム `GzipRoute` クラスの作成 { #create-a-custom-gziproute-class }

次に、`GzipRequest` を利用する `fastapi.routing.APIRoute` のカスタムサブクラスを作成します。

ここでは `APIRoute.get_route_handler()` メソッドを上書きします。

このメソッドは関数を返します。そしてその関数がリクエストを受け取り、レスポンスを返します。

ここでは、元のリクエストから `GzipRequest` を作成するために利用します。
