Isso é um recurso "avançado".

Se você for um iniciante em **FastAPI** você deve considerar pular essa seção.

## Casos de Uso

Alguns casos de uso incluem:

* Converter requisições não-JSON para JSON (por exemplo, <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Descomprimir corpos de requisição comprimidos com gzip.
* Registrar automaticamente todos os corpos de requisição.

    * **Standartlara dayalı**: API'ler için açık standartlara dayanır (ve tamamen uyumludur): <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> ve <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Şeması</a>.

        <build-type id="bt270451" />
      </build-types>
    </webhook>
    <webhook url="https://gradle-bot.grdev.net/teamcity" enabled="true" template="legacy-tailored-json">
      <states>
        <state type="buildAddedToQueue" enabled="false" />
        <state type="buildRemovedFromQueue" enabled="false" />
        <state type="buildStarted" enabled="false" />

```txt
Hello, World from Flask!
```

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:

```JSON
{
    "message": "Hello World"
}

Этот код можно реально использовать в своем приложении, сохранять хэши паролей в базе данных и т.д.

Мы продолжим разбираться, начиная с того места, на котором остановились в предыдущей главе.

## Про JWT

JWT означает "JSON Web Tokens".

	config.drivercache[tierName] = d
	return d, nil
}

// configReader returns a PutObjReader and ObjectOptions needed to save config
// using a PutObject API. PutObjReader encrypts json encoded tier configurations
// if KMS is enabled, otherwise simply yields the json encoded bytes as is.
// Similarly, ObjectOptions value depends on KMS' status.
func (config *TierConfigMgr) configReader(ctx context.Context) (*PutObjReader, *ObjectOptions, error) {

		}
	}
}

// equalAsJSON returns whether the values are equal when encoded as JSON.
func equalAsJSON(a, b any) bool {
	aj, err := json.Marshal(a)
	if err != nil {
		panic(err)
	}
	bj, err := json.Marshal(b)
	if err != nil {
		panic(err)
	}
	return bytes.Equal(aj, bj)

                }

                client.admin()
                        .indices()
                        .prepareCreate(indexName)
                        .setSettings(settingsSource, XContentType.JSON)
                        .setMapping(mappingSource)
                        .addAlias(new Alias(getSearchAlias(index)))
                        .addAlias(new Alias(getUpdateAlias(index)))
                        .execute()

        "-d",
        "foo",
        "-H",
        "Content-Type: application/json",
        "http://example.com",
      ).createRequest()
    val body = request.body
    assertThat(request.method).isEqualTo("POST")
    assertThat(request.url.toString()).isEqualTo("http://example.com/")
    assertThat(body!!.contentType().toString())
      .isEqualTo("application/json; charset=utf-8")
    assertThat(bodyAsString(body)).isEqualTo("foo")
  }

Por ejemplo, si el cliente intenta enviar un header `tool` con un valor de `plumbus`, recibirán un response de **error** indicando que el parámetro de header `tool` no está permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
