#### `Hero` - the *table model*

Then let's create `Hero`, the actual *table model*, with the **extra fields** that are not always in the other models:

* `id`
* `secret_name`

Because `Hero` inherits form `HeroBase`, it **also** has the **fields** declared in `HeroBase`, so all the fields for `Hero` are:

* `id`
* `name`
* `age`
* `secret_name`

	// Parse date header.
	var err error
	date, err = time.Parse(iso8601Format, dateStr)
	if err != nil {
		return cred, "", "", time.Time{}, ErrMalformedDate
	}

	// Query string.
	queryStr := req.Form.Encode()

	// Get canonical request.
	canonicalRequest := getCanonicalRequest(extractedSignedHeaders, payload, queryStr, req.URL.Path, req.Method)

	// Get string to sign from canonical request.

        } else if (url.startsWith("file:") && !url.startsWith("file://")) {
            url = "file://" + url.substring("file:".length());
        }

        // So now we have an url of the form file://<path>

        // We want to eliminate any relative path nonsense and lock down the path so we
        // need to fully resolve it before any submodules use the path. This can happen

 * resource refers to a workgroup in a <code>smb1://workgroup/</code> URL,
 * <li> all browseable shares of a server including printers, IPC
 * services, or disk volumes if this resource is a server URL in the form
 * <code>smb1://server/</code>,
 * <li> or <code>null</code> if the resource cannot be resolved.
 * </ul>
 *
 * @return A <code>String[]</code> array of files and directories,

`dict`、`list`、`str`、`int`などを返すことができます。

Pydanticモデルを返すこともできます（後で詳しく説明します）。

JSONに自動的に変換されるオブジェクトやモデルは他にもたくさんあります（ORMなど）。 お気に入りのものを使ってみてください。すでにサポートされている可能性が高いです。

## まとめ

* `FastAPI`をインポート
* `app`インスタンスを生成
* **パスオペレーションデコレータ**を記述 (`@app.get("/")`)
* **パスオペレーション関数**を定義 (上記の`def root(): ...`のように)

/**
 * A striped {@code Lock/Semaphore/ReadWriteLock}. This offers the underlying lock striping similar
 * to that of {@code ConcurrentHashMap} in a reusable form, and extends it for semaphores and
 * read-write locks. Conceptually, lock striping is the technique of dividing a lock into many
 * <i>stripes</i>, increasing the granularity of a single lock and allowing independent operations

Pydantic을 기반으로 하는, 데이터베이스를 위한 <abbr title="Object-Relational Mapper">ORM</abbr>, <abbr title="Object-Document Mapper">ODM</abbr>을 포함한 외부 라이브러리를 포함합니다.

이는 모든 것이 자동으로 검증되기 때문에, 많은 경우에서 요청을 통해 얻은 동일한 객체를, **직접 데이터베이스로** 넘겨줄 수 있습니다.

반대로도 마찬가지이며, 많은 경우에서 여러분은 **직접 클라이언트로** 그저 객체를 넘겨줄 수 있습니다.

      E e1, E e2, E e3, E e4, E e5, E e6, E e7, E e8, E e9, E e10, E e11) {
    return construct(e1, e2, e3, e4, e5, e6, e7, e8, e9, e10, e11);
  }

  // These go up to eleven. After that, you just get the varargs form, and
  // whatever warnings might come along with it. :(
