And if you go to <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> you will see the response from FastAPI:

/**
 * API action for admin document management.

* Uma função `call_next` que receberá o `request` como um parâmetro.
    * Esta função passará a `request` para a *operação de rota* correspondente.
    * Então ela retorna a `response` gerada pela *operação de rota* correspondente.
* Você pode então modificar ainda mais o `response` antes de retorná-lo.

## API Response

XML response for this API is similar to [AWS STS AssumeRoleWithWebIdentity](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html#API_AssumeRoleWithWebIdentity_ResponseElements)

## Example request and response

Sample request with `curl`:

```sh

        // Should not throw any exception
        int bytesRead = response.readBytesWireFormat(validBuffer, 0);

        assertTrue(bytesRead > 0);
        assertEquals(0x0302, response.getDialectRevision()); // SMB 3.0.2
        assertTrue(response.getMaxTransactSize() > 0);
        assertTrue(response.getMaxTransactSize() <= 16777216); // Within validated limits
    }

    /**

          call.eventListener.followUpDecision(call, response, null)
          return response
        }

        val followUpBody = followUp.body
        if (followUpBody != null && followUpBody.isOneShot()) {
          closeActiveExchange = false
          call.eventListener.followUpDecision(call, response, null)
          return response
        }

        response.body.closeQuietly()

            .withQueryStringParameter("name", "peter"),
        ).respond(response().withBody("Peter the person!"))

      val results =
        (1..20).map {
          executor.submit {
            val response =
              client.newCall(Request((mockServer.secureEndpoint + "/person?name=peter").toHttpUrl())).execute()

            val body = response.body.string()
            assertThat(body).contains("Peter the person")

        "Mock Response",
      )
    for (i in 0..599) {
      val response = MockResponse().setResponseCode(i)
      val expectedReason = reasons[i / 100]
      assertThat(response.status).isEqualTo("HTTP/1.1 $i $expectedReason")
      assertThat(headersToList(response)).containsExactly("Content-Length: 0")
    }
  }

  @Test
  fun setStatusControlsWholeStatusLine() {

                oidcResponse.getErrorObject().getDescription()));
    }
