Following example shows how to list an object and download it locally via `ftp` client:

```
ftp> ls runner/chunkdocs/metadata

package cmd

import (
	"net/http"
	"testing"
)

func BenchmarkURLQueryForm(b *testing.B) {
	req, err := http.NewRequest(http.MethodGet, "http://localhost:9000/bucket/name?uploadId=upload&partNumber=1", http.NoBody)
	if err != nil {
		b.Fatal(err)
	}

	// benchmark utility which helps obtain number of allocations and bytes allocated per ops.
	b.ReportAllocs()

		WelcomeMessage: fmt.Sprintf("Welcome to '%s' FTP Server Version='%s' License='%s'", MinioStoreName, MinioLicense, Version),
		Driver:         NewFTPDriver(),
		Port:           port,
		Perm:           ftp.NewSimplePerm("nobody", "nobody"),
		TLS:            tls,
		KeyFile:        tlsPrivateKey,
		CertFile:       tlsPublicCert,

The application-layer can also do blocking reads. If the application asks to read and there's nothing available, we need to hold that thread until either the bytes arrive, the stream is closed, or a timeout elapses. If we get bytes but there's nobody asking for them, we buffer them. We don't consider bytes as delivered for flow control until they're consumed by the application.

# Request Body

Cuando necesitas enviar datos desde un cliente (digamos, un navegador) a tu API, los envías como un **request body**.

Un **request** body es un dato enviado por el cliente a tu API. Un **response** body es el dato que tu API envía al cliente.

When you need to send data from a client (let's say, a browser) to your API, you send it as a **request body**.

A **request** body is data sent by the client to your API. A **response** body is the data your API sends to the client.

## Importe `Field`

Primeiro, você tem que importá-lo:

{* ../../docs_src/body_fields/tutorial001.py hl[4] *}

/// warning | Aviso

Note que `Field` é importado diretamente do `pydantic`, não do `fastapi` como todo o resto (`Query`, `Path`, `Body`, etc).
