SSE es un estándar para hacer streaming de datos desde el servidor al cliente sobre HTTP.

Cada evento es un pequeño bloque de texto con “campos” como `data`, `event`, `id` y `retry`, separados por líneas en blanco.

Se ve así:

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```

								<group>root</group>
							</mapper>
						</data>
						<!-- Adds systemd file -->
						<data>
							<type>file</type>
							<src>${project.build.directory}/generated-packaging/deb/systemd/fess.service</src>
							<dst>${packaging.fess.systemd.dir}/fess.service</dst>
						</data>
						<!-- Adds systemd/sysctl.d configuration file -->
						<data>
							<type>file</type>

  @Override
  protected Table<String, Integer, Character> create(@Nullable Object... data) {
    Table<String, Integer, String> table = HashBasedTable.create();
    checkArgument(data.length % 3 == 0);
    for (int i = 0; i < data.length; i += 3) {
      String value = (data[i + 2] == null) ? null : (data[i + 2] + "transformed");
      table.put((String) data[i], (Integer) data[i + 1], value);
    }
    return transformValues(table, FIRST_CHARACTER);
  }

Якщо ви перевірите `/docs`, там буде показано, що поле `data` очікує байти, закодовані в base64:

<div class="screenshot">

</div>

Ви можете надіслати запит так:

```json
{
    "description": "Some data",
    "data": "aGVsbG8="
}
```

/// tip | Порада

`aGVsbG8=` - це кодування base64 для `hello`.
