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。

ただし、フロントエンドで最終ユーザーにどう表示するかは自由です。

また、データベースのモデルでは任意の別名を使って構いません。

        mockProcessHelper.setExitValue(1);
        mockProcessHelper.setOutput("Timeout occurred");

        String result = suggestJob.execute();

        assertNotNull(result);
        // The actual execution flow may not reach the timeout message
        assertTrue(result.contains("Session Id:"));
    }

    // Test executeSuggestCreator with Windows environment
    @Test
    public void test_executeSuggestCreator_windows() {

        // Prepare buffer with specific type value
        testBuffer[0] = 0x01; // revision
        testBuffer[1] = 0x00; // padding
        testBuffer[2] = 0x04; // type low byte
        testBuffer[3] = (byte) 0x80; // type high byte (0x8004)
        // Set all offsets to 0
        for (int i = 4; i < 20; i++) {
            testBuffer[i] = 0;
        }

   */
  public static final byte DC1 = 17; // aka XON

  /**
   * Transmission On: Although originally defined as DC1, this ASCII control character is now better
   * known as the XON code used for software flow control in serial communications. The main use is
   * restarting the transmission after the communication has been stopped by the XOFF control code.
   *
   * @since 8.0
   */

### Include a *path operation* { #include-a-path-operation }

We can also add *path operations* directly to the `FastAPI` app.

Here we do it... just to show that we can 🤷:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[21:23] title["app/main.py"] *}

and it will work correctly, together with all the other *path operations* added with `app.include_router()`.

I'll show you some concrete examples in the next chapters.

Then the next concepts to consider are all about the program running your actual API (e.g. Uvicorn).
