Щоб гарантувати, що ви не повертаєте більше даних, ніж слід, прочитайте документацію [Навчальний посібник - Модель відповіді - Тип повернення](../tutorial/response-model.md).

* The logic can be shared by multiple endpoints to do things like error early, authentication, etc.
* They need to handle cleanup (e.g., DB sessions, file handles), using dependencies with `yield`
* Their logic needs input data from the request, like headers, query parameters, etc.

## Dependencies with `yield` and `scope`

When using dependencies with `yield`, they can have a `scope` that defines when the exit code is run.

   * eagerly fetches data for each source when iterated (rather than producing sources that only
   * load data through their streams). Prefer using the {@link #concat(Iterable)} overload if
   * possible.
   *
   * @param sources the sources to concatenate
   * @return a {@code ByteSource} containing the concatenated data
   * @throws NullPointerException if any of {@code sources} is {@code null}

## 「Form Data」とは { #what-is-form-data }

HTML フォーム（`<form></form>`）がサーバーにデータを送る方法は、そのデータに対して通常「特別な」エンコーディングを用い、JSON とは異なります。

**FastAPI** は JSON ではなく、適切な場所からそのデータを読み取るようにします。

/// note | 技術詳細

ファイルを含まない場合、フォームからのデータは通常「メディアタイプ」`application/x-www-form-urlencoded` でエンコードされます。

        when(response.getHeaderStart()).thenReturn(0);

        // Write FileInternalInfo data at the large offset
        SMBUtil.writeInt8(0x123456789ABCDEFL, buffer, 1000);

        int result = response.readBytesWireFormat(buffer, bufferIndex);

        // Should return at least to the end of the data
        assertTrue(result >= 900); // 1000 + 8 - 100
        assertNotNull(response.getInfo());
    }

 * interface easier to implement for certain types of data sources.
 *
 * <p>{@code Iterator} requires its implementations to support querying the end-of-data status
 * without changing the iterator's state, using the {@link #hasNext} method. But many data sources,
 * such as {@link java.io.Reader#read()}, do not expose this information; the only way to discover
 * whether there is any data left is by trying to retrieve it. These types of data sources are
