/// info

To send data, you should use one of: `POST` (the more common), `PUT`, `DELETE` or `PATCH`.

Sending a body with a `GET` request has an undefined behavior in the specifications, nevertheless, it is supported by FastAPI, only for very complex/extreme use cases.

```console
$ pip install python-multipart
```

This is because **OAuth2** uses "form data" for sending the `username` and `password`.

///

Run the example with:

<div class="termy">

```console
$ fastapi dev main.py

}

func (m *muxServer) send(msg message) {
	m.sendMu.Lock()
	defer m.sendMu.Unlock()
	msg.MuxID = m.ID
	msg.Seq = m.SendSeq
	m.SendSeq++
	if debugPrint {
		fmt.Printf("Mux %d, Sending %+v\n", m.ID, msg)
	}
	gridLogIf(m.ctx, m.parent.queueMsg(msg, nil))
}

func (m *muxServer) close() {
	m.cancel()
	m.recvMu.Lock()
	defer m.recvMu.Unlock()

	if m.inbound != nil {

			t.Errorf("want %q, got %q", testPayload+strconv.Itoa(n), string(resp.Msg))
		}
		if n == 10 {
			close(stream.Requests)
			continue
		}
		n++
		t.Log("sending new client request")
		stream.Requests <- []byte(strconv.Itoa(n))
	}
	t.Log("EOF. 10 Roundtrips:", time.Since(start))
}

func testStreamCancel(t *testing.T, local, remote *Manager) {

...isso deve funcionar:

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

E claro, você pode definir alguns parâmetros como obrigatórios, alguns possuindo um valor padrão, e outros sendo totalmente opcionais:

{* ../../docs_src/query_params/tutorial006_py310.py hl[8] *}

Nesse caso, existem 3 parâmetros de consulta:

* `needy`, um `str` obrigatório.
* `skip`, um `int` com o valor padrão `0`.

            final SearchRequestParams params, final OptionalThing<FessUserBean> userBean) {
        if (logger.isDebugEnabled()) {
            logger.debug("Sending query to searchers: query={}", query);
        }
        final int pageSize = params.getPageSize();
        final int startPosition = params.getStartPosition();
        if (startPosition * 2 >= windowSize) {

/// tip

If you want to call `async` functions in your tests apart from sending requests to your FastAPI application (e.g. asynchronous database functions), have a look at the [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} in the advanced tutorial.

## Version 3.14.6

 *  Fix: Don't crash if the connection is closed when sending a degraded ping. This fixes a
    regression that was introduced in OkHttp 3.14.5.
