## Parámetros de query requeridos

Cuando declaras un valor por defecto para los parámetros que no son de path (por ahora solo hemos visto parámetros de query), entonces no es requerido.

Si no quieres añadir un valor específico sino solo hacerlo opcional, pon el valor por defecto como `None`.

Pero cuando quieres hacer que un parámetro de query sea requerido, puedes simplemente no declararle un valor por defecto:

```Python hl_lines="6-7"

	}
	if n != len(p) {
		err = io.ErrShortWrite
		b.closeWithErr(err)
	}
	return n, err
}

func (b *streamingBitrotWriter) Close() error {
	// Close the underlying writer.
	// This will also flush the ring buffer if used.
	err := b.iow.Close()

	// Wait for all data to be written before returning else it causes race conditions.
	// Race condition is because of io.PipeWriter implementation. i.e consider the following

        dstIndex += writeHeaderWireFormat( dst, dstIndex );
        dstIndex += writeAndXWireFormat( dst, dstIndex );
        length = dstIndex - start;

        if( digest != null ) {
            digest.sign( dst, headerStart, length, this, response );
        }

        return length;
    }

    /*
     * We overload this because we want readAndXWireFormat to
     * read the parameter words and bytes. This is so when
