# Request Forms and Files

Puedes definir archivos y campos de formulario al mismo tiempo usando `File` y `Form`.

/// info | Información

Para recibir archivos subidos y/o form data, primero instala <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, actívalo y luego instálalo, por ejemplo:

        CountDownLatch startLatch = new CountDownLatch(1);
        CountDownLatch doneLatch = new CountDownLatch(threadCount);
        ExecutorService executor = Executors.newFixedThreadPool(threadCount);

        // Create test data
        byte[] testData = new byte[64];
        for (int i = 0; i < testData.length; i++) {
            testData[i] = (byte) i;
        }

        // Run concurrent updates

  buildString {
    append("-----BEGIN CERTIFICATE-----\n")
    encodeBase64Lines(encoded.toByteString())
    append("-----END CERTIFICATE-----\n")
  }

internal fun StringBuilder.encodeBase64Lines(data: ByteString) {
  val base64 = data.base64()
  for (i in 0 until base64.length step 64) {
    append(base64, i, minOf(i + 64, base64.length)).append('\n')
  }
